ver the past 40 years, environmental educators throughout the world have been aiming to motivate and empower students to work toward a sustainable future, but we are far from having achieved this goal. Urgency is evident in the warning issued by more than 15,000 scientists from 184 countries: “to prevent widespread misery and catastrophic biodiversity loss, humanity must practice a more environmentally sustainable alternative to business as usual… Soon it will be too late to shift course away from our failing trajectory, and time is running out. We must recognize, in our day-to-day lives and in our governing institutions, that Earth with all its life is our only home” (Ripple et al. 2017).
In this tumultuous era of ecocatastrophes, we need every child to grow up caring deeply about how to live sustainably on our planet. We need some to become leaders and all to become environmentally minded citizens and informed voters. Going beyond buying greener products and aiming for energy efficiency, we must find ways to balance human well-being, economic prosperity, and environmental quality. These three overlapping goals form the “triple bottom line,” aiming to protect the natural environment while ensuring economic vitality and the health of human communities. This is the basis for sustainable development, defined by the United Nations as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” (WCED 1987). Strong economies of course are vital, but they cannot endure at the expense of vibrant human societies and a healthy environment.
Within the formal K–12 setting, a primary hurdle in teaching for sustainability is the need to meaningfully address environmental issues within the constraints of established courses and curricular mandates. In the United States, for example, the Next Generation Science Standards designate science learning outcomes for grades K–12 (NGSS 2013). These standards misrepresent sustainability challenges by portraying them as affecting all humans equally, overlooking the substantial environmental justice issues evident within the United States and throughout the world. Another oversight is that these standards portray environmental issues as solvable through the application of science and technology, neglecting the potential roles of other sources of knowledge (Feinstein and Kirchgasler 2015).
One might argue that K–12 students are too young to tackle looming environmental issues. However, they are proving up to the challenge, such as through project-based learning in which they explore issues and pose potential solutions. This may involve designing and conducting scientific investigations, with the possibility of participating in citizen science. Case-study research into teen involvement in community-based citizen science both in and out of school settings revealed that the participants developed various degrees of environmental science agency. Reaching beyond understanding of environmental science and inquiry practices, this term’s definition also includes confidence in one’s ability to take positive stewardship actions (Ballard et al. 2017). The study concluded that the development of environmental science agency depended on involving teens in projects that included these three factors: investigating complex social–ecological systems with human dimensions, ensuring rigorous data collection, and disseminating scientific findings to authentic external audiences. Educators interested in undertaking such endeavors can make use of free resources, including an ever-growing compendium of lesson plans for use with citizen-science projects (SciStarter 2018) and a downloadable curriculum that leads students through the processes of designing and conducting their own investigations, especially those inspired by outdoor observations and participation in citizen science (Fee 2015).
We need to provide opportunities for students to investigate environmental issues, collect and analyze data, and understand the role of science in making informed decisions. But sustainability challenges will not be resolved through scientific approaches alone. Students also need opportunities to connect deeply with people from drastically different cultures and think deeply about their own lifestyles, goals, and assumptions. As faculty members of the Educator Academy in the Amazon Rainforest, we have had the privilege of accompanying groups of US teachers through 10-day expeditions in the Peruvian Amazon. Last summer, we asked Sebastián Ríos Ochoa, leader of a small indigenous group living deep in the rainforest, for his view of sustainability. Sebastián responded that he and his community are one with the forest—it is their mother, providing life and wholeness. Reflecting on the changes occurring at an accelerating rate even in remote rainforest communities, Sebastián went on to state that his greatest wish is for his descendants to forever have the opportunity to continue living at one with their natural surroundings (Sebastián Ríos Ochoa, Maijuna Community Leader, Sucusari, Peru, personal communication, 18 July 2017). After decades of struggle during which their rainforest resources were devastated by outside loggers and hunters (Gilmore 2010), this indigenous group has regained control over their ancestral lands and the power to enact community-based conservation practices. Their efforts provide compelling examples of how people (no matter how few in number and how marginalized) can effect positive change.
In collaboration with leaders of Sebastián’s remote Peruvian community and a nongovernmental organization with a long history of working in the area, US educators are creating educational resources designed to instill this same sense of responsibility in children growing up without such direct connections to nature. Rather than developing a sense of entitlement to ecologically unsustainable ways of life, we need children to build close relationships with the natural world, empathy for people with different ways of life, and a sense of responsibility to build a better tomorrow. Although the Amazon rainforest is a common topic in K–12 and undergraduate curricula, typically it is addressed through textbook readings. Instead, we are working to engage students in grappling with complex real-world issues related to resource use, human rights, and conservation needs. This is accomplished through exploration of questions such as the following: (a) How do indigenous cultures view, interact with, and perceive their role in the natural world, and what can we learn from them? (b) How do our lives influence the sustainability of the rainforest and the livelihoods of the people who live there? (c) Why is the Amazon important to us, no matter where we live? (d) How does this relate to the triple-bottom-line goal of balancing social well-being, economic prosperity, and environmental protection?
Investigating the Amazon’s impacts on global weather patterns, water cycling, carbon sequestration, and biodiversity leads students to see that the triple bottom line transcends cultures and speaks to our global need for a sustainable future for humans and the environment throughout the world. Tracing the origin of popular products such as cocoa and palm oil, they investigate ways to participate in conservation initiatives aiming for ecological sustainability both at home and in the Amazon.
Another way to address global issues is to have students calculate the ecological footprint attributable to their lifestyles, leading into consideration of humankind vastly overshooting Earth’s ability to regenerate the resources and services on which our lives depend. In 2017, August 2 was determined to be the date on which humanity had overshot Earth’s regenerative capacity for the year because of unsustainable levels of fishing, deforestation, and carbon dioxide emissions (Earth Overshoot Day 2017). The fact that this occurs earlier each year is a stark reminder of our ever-diminishing ability to sustain current lifestyles. And as is continually illustrated in news of climate disasters, human societies with small ecological footprints can be tragically vulnerable to such calamities (e.g., Kristof 2018).
Engaged in such activities, students in affluent settings may end up deriving solutions that shake the very tenet of the neoliberal capitalistic societies in which they live. To what extent should students be encouraged to challenge the injustices and entitlements on which world economies currently are based, such as by seeking ways to transform the incentive structures under which business and government decisions currently are made? Should they be asked to envision ways of overturning the unsustainable ways in which modern societies deplete resources, emit carbon dioxide, and destroy the habitats needed to support diverse forms of life on Earth?
Anyone who gives serious consideration to the environmental degradation and social-injustice issues in today’s world faces the risk of sinking into depression at the thought of a hopeless future. What can we possibly accomplish that will not simply be too little, too late? Reflecting on this inherent tension, Jon Foley (2016) stated, “If you’re awake and alive in the twenty-first century, with even an ounce of empathy, your heart and mind are going to be torn asunder. I’m sorry about that, but it’s unavoidable — unless you simply shut down and turn your back on the world. For me, the only solution is found in the space between awe and anguish, and between joy and despair. There, in the tension between two worlds, lies the place we just might find ourselves and our life’s work.”
Education for sustainability must build on this creative tension, capturing students’ attention while inspiring them to become forces for positive change.
Collaboration with the Maijuna is made possible through work of the OnePlanet nonprofit organization (https://www.oneplanet-ngo.org) and Amazon Rainforest Workshops (http://amazonworkshops.com).
Nancy Trautmann was supported through a fellowship with the Rachel Carson Center for Environment and Society in Munich, Germany, to develop curricular resources that highlight the Maijuna to inspire U.S. youth to care about conservation issues at home and abroad.

Is Science Communication? Can students, moving around and talking, do science?
by Jim Martin
CLEARING Associate Editor
You’re trying to answer a question. Student work groups have designed their own investigations to understand the question, develop inquiries to investigate what they have found and thought about, then present their findings to the other work groups in a symposium. There are many processes going on here. Let’s look at a few as they engage them to see what emerges in addition to discovering and testing possible answers to the original question.
Start small. In groups, you help students learn to communicate effectively. How to say, “Here’s what I think, and why;” and to listen and respond when other group members do the same. This is very basic to developing effective work groups. You have them keep notes on these conversations, and use them to elicit concepts, plan work, etc. (Basic, but essential. They need to know why they think what they do, and make what they think and why clear to others. And to learn to be advised or informed by others in their group.)
When your groups are communicating effectively, you observe for outcomes of their collaborative discussions. Do they understand their data, its patterns, its shape in graphs, etc. Are they showing signs of being able to relate data patterns to their question: Is it answered? What is the convincing evidence? What if the evidence doesn’t support their guesses about the answer to question? Or, does their question itself come into question? Are they becoming less mechanical and more purposeful in their work?
Further questions can move the groups along the learning curve by developing their critical thinking capacities: Are their interpretations of data supported by evidence? How confident are they of their data? Can they explain or justify data interpretations they have made, and their validity? What do their interpretations say about possible next steps?
You can continue to build on this conceptual foundation, each step easier because the foundation is becoming broad and more stable. You have them assess the design of their investigation and interpretations of data: How certain are they that they got the right data and used the best techniques of data acquisition? How certain are they that their data do, in fact, tell them what they need to know? Has their knowledge and expertise increased during this process? How much do they really know? Questions like these will tend to focus their thoughts on how they are learning and doing. Metacognition. Students who know how to learn know how to learn. Communication within effective work groups helps generate this capacity.
When they are ready, you have the groups report in a symposium. This is where their communication skills will be called upon to build conceptual understandings. How familiar are they with their evidence and its interpretation? How well do they comprehend other groups’ data and interpretations? How well do they generalize what they’ve learned and developed about collaborative communication within their work groups? Do they move it outward to carry on effective discussion with all of the work groups in the class? When an entire class develops the capacity to engage in substantive conversation about what they are learning, they’ll learn and nail down more than you could ever teach them using the publishers’ prepared materials and recommendations in the Teachers’ Editions.
Learning about science, but not doing science, does not develop the capacities described here. By only collecting and reporting data, students don’t engage the critical thinking capacities of their brain. I’ve observed science classes in which students looked up the boiling point of a liquid, say water, boiled the liquid and noted that it did boil at that temperature. What do they communicate amongst themselves? Is communication actually involved here? Or, are they simply engaging a perfunctory ritual? Might they have learned more if they had heated 3 or 4 liquids, noted their boiling points (or figured out how they’d know the boiling points, then test that), then looked up boiling points and made a guess about what their liquids were?)
Nor do they develop their capacity for conceptual learning when they simply learn about science, and commit science facts to memory. When students do engage in self-directed inquiries, examine the relevance of their collected data, critique it and the process of collecting it, and formulate interpretations they agree upon, they become involved and invested in the work, and empowered as persons. Engaging life. Engaged students are learning students. What our schools need today.
There’s not a lot of information out there on how to engage this part of teaching. There should be. This kind of work supports critical thinking, so it is of value. Critical thinking uses a part of the cortex that is especially well-organized for conceptual learning. That’s the prefrontal cortex, where relevant information from associative memories throughout the brain are brought together in working memory to nail down this new learning, then send it back out to associative memory; not as a fact to memorize for a test then forget, but as something more akin to common sense – something integrated into associative memory that you ‘just know.’
This critical thinking system turns on when you ask a question that is meaningful to you, and seek an answer to it. Science inquiry is a perfect complement and extension of this cortical learning system. In contrast, learning simply to prepare for a test won’t, of itself, entrain critical thinking. Instead, because of its aversive nature, learning content in order to answer test questions is accompanied by some level of anxiety, and entrains the limbic system, which isn’t good at engaging critical thinking. At least in this context, learning facilitated by anxiety about passing a test.
As the Common Core State Standards (CCSS) and Next Generation Science Standards (NGSS) continue to influence teachers’ and students’ experience in school, they present some level of anxiety to many, whether from an unfamiliar expectation for performance, change from structured, curriculum-directed teaching and learning to a more open-ended, active learning model, or from increased paperwork and accounting with no accommodating increase in free time for such work. Anxiety is processed through the limbic system, which impacts how the brain learns; which of its resources are freed for the task. As student and teacher stress levels increase, it becomes increasingly difficult to engage critical thinking. Instead, the limbic system, busy processing anxiety, increasingly limits communication with the prefrontal cortex, where critical thinking does its work. Instead, learning is limited to simple thoughts, which remain connected solely to the need to pass questions on a test, with little or no integration into associative memory, as occurs in critical thinking.
On the other hand, when students and teachers are free to explore new learnings (which the CCSS and NGSS seem to be interested in), to ask questions and seek answers to them, the limbic system supports this work with a heightened sense of pleasure and excitement, and feelings of well-being and inquisitiveness. And by assuring the doors to the prefrontal cortex are open.The different limbic involvements in learning are entrained by the properties of the learning environment. As they were when our brain evolved in the savannah during the Pleistocene. Might we use that history to revisit how we teach? How we organize student-student interactions while they learn? In the classroom and on-site in the natural world? In these cases, the limbic supports the work of the cortex, especially the prefrontal cortex, where working memory resides, and the brain’s conscious executive functions do their work. Work in which goals direct effort, reasoning and abstract thought are supported, and critical thinking takes place. Where we actively construct knowledge and commit it to long-term associative memory; ask questions, design investigations, develop needs-to-know which drive us into the information we seek, desire to complete and communicate our work.
When we are driven only by anxiety about not being able to answer questions on tests, this wonderful part of our brain is lost to us. The limbic system limits its use, and we simply memorize disconnected bits of information long enough to use them on a test, then forget. Are we teaching for fight or flight, or for higher-order critical thinking?
Used knowledgably, communication as practiced in doing science has the capacity to produce a foundation for critical thinking. By the information it generates, the testing of the information, and its processing and communication, it involves and invests students in critical thinking; in using their prefrontal cortex, its executive and working memory functions. The key feature is that the students, not the teacher, are involved in constructing knowledge. The teacher, while responsible for producing an environment where a constructivist approach to learning will probably happen, becomes a facilitator of their work. A difficult transition for many of us to make. I went into it willingly, but once committed, sorely missed lecturing and wowing students with the wondrous things I could show them in the lab. In spite of this, when I would pull out my old lesson plans, it would be immediately clear to me that this constructivist model was much, much more effective and empowering. And I eventually discovered this was because it used those sites and connections in the brain which were organized to engage conceptual learning. Something my pre-service and graduate education in teaching never addressed. It should have. Had it, and we learned as our brain is organized to learn, we just might have learned well.
Communication, when it is substantive, has the capacity to facilitate critical thinking. It does this by requiring us to consider what we are saying and doing, which is a readily useable road to the prefrontal cortex and working memory. Sort of like working in a shared workspace, a place with all the resources and facilities you need to focus on what you are learning, and the executive capacity to follow up on what you have learned.
This is a regular feature by CLEARING “master teacher” Jim Martin that explores how environmental educators can help classroom teachers get away from the pressure to teach to the standardized tests,and how teachers can gain the confidence to go into the world outside of their classrooms for a substantial piece of their curricula.

It Takes a Community to Raise a Scientist:
A Case for Community-Inspired Research and Science Education in an Alaskan Native Community
By Nievita Bueno Watts and Wendy F. Smythe
The quote, “lt takes a village to raise a child,” is attributed to African tradition and carries over to Alaskan Native communities as well (Hall, 2000). Without the support of their community and outside resources, Alaska Native children have a difficult time entering the world of science. Yet increasing the awareness of science, as a tool to help a tribal community monitor and maintain the health of their environment, introduces conflicts and misconceptions in context of traditional cultural practices. Rural communities depend upon traditional food harvested from the environment such as fish, wild game, roots, and berries. In many Native Alaskan villages the health of the environment equals the health of the people (Garza, 2001) . Integrating science with culture in pre-college education is a challenge that requires sensitivity and persistence.
The Center for Coastal Margin Observation and Prediction (CMOP) is a multi-institutional, National Science Foundation (NSF) Science and Technology Center that takes an interdisciplinary approach to studying the region where the Columbia River empties into the Pacific Ocean. Two of CMOP’s focus areas are biogeochemical changes affecting the health of the coastal margin ecosystem, and socio-economic changes that might affect the lives of people who harvest and consume fish and shellfish.
The Columbia River waters touch the lives and livelihoods of many people, among them a large number of Pacific Northwest lndian tribes. These people depend on the natural and economic resources provided by the Columbia River. Native peoples from California through Alaska also depend on resources from their local rivers, and, currently, many tribes are developing-a workforce trained with scientific skills to manage their own natural resources in a way that is consistent with their traditional way of life. The relationship between Traditional Knowledge (TK) and practices, which are informed by centuries of observation, experimentation and carefully preserved oral records, and Western Science, which is deeply rooted in the philosophies and institutions of Europe, is often an uneasy one.
National progress is being made to open pathways for individuals from Native communities to Western Science higher education programs and back to the communities, where tribal members are empowered to evaluate and monitor the health of their environment. CMOP is part of this national movement. CMOP science is developing tools and techniques to observe and predict changes in the river to ocean system. CMOP education, an essential element of CMOB supports American lndian/Alaska Native students in pursuing academic and career pathways focusing on coastal margin sciences (Creen et al., 2013). One of CMOP’s initiatives is the CMOP- School Collaboratories (CSC) program.
The CMOP-school Collaboratories (CSC) program is based on the idea that Science, Technology, Engineering, and Mathematics (STEM) pathway development requires an intensive and sustained effort to build relationships among science educators, students, school personnel, and the tribal community. The over-arching goal is to broaden participation in STEM disciplines. CMOP educators developed the CSC model that includes integration strategies for a community, development of appropriate lessons and field experiences and student action projects that connect local and traditional knowledge with science. Educational experiences are place- based, multi-disciplinary and culturally relevant. The objective is to open students’ minds to the reality of the need for scientists with many different world views and skill sets working together to address our planet’s pressing problems in a holistic manner. CMOP seeks to encourage these students to be part of that solution using both Traditional Knowledge and STEM disciplines.
The program encourages STEM education and promotes college preparatory awareness. This CSC program has three unique characteristics: it introduces coastal margin science as a relevant and viable field of employment; it integrates STEM learning with Traditional Knowledge; and, it invites family and community members to share science experiences. The example presented in this article describes a four-year program implemented in a small village in Southeast Alaska, 200 miles from the capital city of Juneau.
Figure 1: Students, scientists, a cultural expert. and a teacher with scientific equipment used to collect data from the river.
ALASKA NATIVE VILLAGE CASE STUDY
Wendy Smythe, a CMOP doctoral candidate and principal investigator for an NSF Enhancing Diversity in the Geosciences (OEDC) award, is an Alaska Native Haida. As she advanced in her own education, she wanted to share what she had learned with the youth of her tribal community, striving to do so with the blessing of the tribal Elders, and in a way that respected the Traditional Knowledge of the Elders. Dr Bueno Watts is a mentor and expert on broadening participation. She acts in an advisory capacity on this project.
The village school consists of l5 staff members and 50 K-l2 students, with the school experiencing high administration turnover rates. ln the first two years of the program we recruited non-native graduate students to participate in the CSC program. This effort provided them experience working in Native communities. ln the last two years we recruited Native American undergraduate interns to teach lessons, assist with field activities and provide students with the opportunity to become familiar with Native scientists [Figure 1]. lnterns formed part of the science team.
STEPS TO GAIN ENTREE TO A VILLAGE
The community must support the concept to integrate science education with traditional practices. Even for this Alaska Native (Smythe), the process of building consensus from the tribe and gaining approval from the Elders and school district for the program was a lengthy one. The first step required letters of support from school district and tribal leaders. The difference in geographical locations proved difficult until Smythe was able to secure an advocate in the tribe who spoke for her at tribal meetings. Face-to-face communications were more successful than distance communications. Persistence proved to be the key to achieving success at getting the consensus of community leaders and school officials’ support. This was the top lesson of l0 learned from this project (Table l).
Traveling to the school to set up the program is no small feat and requires extensive coordination of transportation and supplies. A typical trip requires a day-long plane ride, overnight stay in a nearby town to prepare and gather supplies, a three-hour ferry ride, acquisition of a rental truck and a one-hour drive. Accommodations must be made to board with community members.
The development of appropriate lessons for the curriculum engaged discussions with tribal Elders and community Ieaders on an individual basis. Elders agreed to provide videoed interviews and were given honoraria as a thank you for their participation. Smythe asked the Elders what scientists could do to help the community, what stories can be used, where students and educators could work in the community to avoid intruding on sacred sites, and what information should not be made public. Once Elders agreed to provide interviews and share stories, other community members began to speak about their lives and concerns. This included influence of boarding schools, Iife as it was in the past, and changes they would like to see within the community. This was a significant breakthrough.
Table l . Lessons Learned: ten things to consider when developing a science program with Native communities
1. Persistence is key.
2. Face to-face communication is vital and Lakes time.
3. A community advocate with influence and respect in the community is critical.
4. Consult with the Elders first. They have their finger on the pulse of the community and are the center “of the communication network. Nothing happens without their approval. Find out what it is okay to talk about and where your boundaries are and abide by them. lnclude funds for honorariums in your proposal. Elders’ time and knowledge is valuable and they should be compensated as experts.
5. Partner with individuals or groups, such as the Department of Natural Resources.
6. Find a relevant topic. Be flexible with your curriculum choice. It must reflect the needs and interests of the community and the abilities of the teacher you are working with.
7 . Be prepared, bring supplies with you. Ship items in advance if going to a remote location
8. Have the ability to provide individual instruction for students who need it to prepare projects and practice giving presentations.
9. lnvolve the community. Hold events in a community center to encourage everyone to attend.
10. View your involvement as a long-term investment in a committed community relationship.
ln addition to the Elders, support was needed from a natural resources representative who functioned as a liaison between our group and the community members. This person’s role is found in most villages and could be the head of the Department of Natural Resources or a similar tribal agency that oversees fish, wildlife, and natural resources. This person provides a critical link between the natural environment and the community. The next step is to go in the field with the natural resources representative, science teachers, EIders, and interested students to identify a meaningful focus for the community. lnitially we focused the project with a scientist’s view of teaching microbiology and geology of mineral deposition in a river ecosystem. However, the team found community interest low and no enthusiasm for this project.
Upon our return to the village, the team and CMOP educators found the focus, almost by accident. We were intrigued by “boil water” notices posted both at the home in which we were staying and on the drinking fountains at the school: The students were all talking about water, as were the Elders. It was clear that the community cared about their water quality. The resulting community-inspired research educational plan was based on using aquatic invertebrate bioindicators as predictors of water quality (Adams, Vaughan & Hoffman Black, 2003). This student project combined science with community needs (Bueno Watts, 2011).
The first classroom lessons addressed water cycle and watershed concepts (Wolftree, 2OO4), which were followed by a field lesson on aquatic invertebrates. Students sampled different locations in an effort to determine biodiversity and quantity of macroinvertebrates. While students were sitting at the river’s edge, the site was described in the students’ Alaska Native tongue by a cultural expert, and then an English translation was provided. This introduced the combination of culture and language into the science lesson.
Figure 2: Students use data loggers to collect data on temperature, pH, and location.
The village water supply comes from a river that runs through the heart of the community. Thus, this river was our primary field site from which students collected water for chemical sampling and aquatic invertebrates using D-loop nets. Physical and chemical parameters of the river were collected using Vernier LabQuest hand-held data loggers. Students recorded data on turbidity, flow rate, temperature, pH, and pinpointed locations using CPS coordinates (Figure 2].
Aquatic invertebrate samples were sorted, classified, counted, recorded, and examined through stereoscopes back in the classroom. Water chemistry was determined by kits that measured concentrations of alkalinity, dissolved oxygen, iron, nitrate/nitrite, dissolved carbon dioxide, and phosphate.
Microbiology assessments were conducted in an effort to detect fecal coliform (using m_FC Agar plates). Students tested water from an estuary, river, drinking fountain, and toilet. Results from estuarine waters showed a high number of fecal coliform, indicating that a more thorough investigation was warranted While fecal coliform are non-disease causing microorganisms, they originate in the intestinal tract, the same place as disease causing bacteria, and so their presence is a bioindicator of the presence of human or animal wastes (Figure 3).
Students learned that the “dirty water” they observed in the river was actually the result of a natural process of acidic muskeg fluids dissolving iron minerals in the bedrock, no health danger. The real health threat was in the estuarine shellfish waters. Students shared all of their results with their families, after which community members began to approach the CMOP science team with questions about the quality of their drinking water. The community was relieved to find that the combined results of aquatic invertebrate counts and water chemistry indicated that the water flowing through their town was healthy. However they were concerned about the potential contamination as indicated by fecal coliform counts in the local estuary where shellfish were traditionally harvested.
ln the second year, a curriculum on oceanography developed by another STC, the Center for Microbial Oceanography: Research and Education (C-MORE) was introduced (Bruno, Wiener, Kimura & Kimura, 2011). Oceanography lessons focused on water density as a function of salinity and temperature, ocean currents, phytoplankton, and ocean acidification, all areas of research at CMOP. Additional lessons used local shipworms, a burrowing mollusk known to the community, as a marine bioindicator (CMOP Education, 2013). Students continued to conduct bioassessments of local rivers and coastal marine waters.
Figure 3: Students sort and count aquatic invertebrates as a bioindicator of river health.
Students used teleconferencing technology to participate in scanning electron microscope (SEM) session with a scientist in Oregon who had their samples of aquatic invertebrates. Students showcased their experiments during parent day. Five students (l0%) had parents and/or siblings who attended the event.
As a reward for participation in the science program, two students were chosen to attend the American lndian Science and Engineering Society (AISES) 2009 conference in Oregon. Travel expenses were shared between the school, CSC program, and the tribe. ln the following three years an additional ten students attended the AISES conference and presented seven science research posters in New Mexico. Minnesota and Alaska. ln 2012, one student won 3rd place for her shipworm poster presentation (Figure 5). These conference presentations enabled some students to take their first trip out of Alaska.
ln May 20ll the first Science Symposium for grades K-12 allowed students to share their science projects with parents, Elders, and tribal community members. Both students and teachers were prepared on how to do a science fair project. Work with students had to be accomplished on a one-on-one basis, and members of the team were paired with students to assist with completing projects and polishing presentations. Students were not accustomed to speaking publicly, so this practice was a critical step.
The event was held at the local community center, which encouraged Elders and other community members to attend.
Elders requested a public education opportunity to teach the community about watersheds and the effects of logging. Our team incorporated this request into the science symposium. Students led this project by constructing a 5D model of the watershed for display. People could simulate rainfall, see how land use affects runoff and make runoff to river estuary connections. Scientists conducted hands-on demonstrations related to shipworms, local geology, ocean acidification and deepsea research. Language and culture booths were also included. During the symposium, a video of one of the interviews we had conducted with an Elder was shown as a memorial to his passing. The symposium was considered a huge success and was attended by 35 students and 50 community members.
The CSC program garnered results that could not have been predicted at the outset. For example, the tribe requested our input when deciding which students should attend a tribal leadership conference and summer camp. Three student interns participated in a collaborative project with the tribe to conduct bio-assessment studies of local rivers and a key sockeye breeding lake. lnterns operated a remotely operated underwater vehicle (ROV) for data collection, resulting in video documentation of the salmon habitat. ln addition to the bio-assessment, the interns conducted interviews with Elders about the rivers in the monitoring project. The results of this study were used to stop logging around sockeye spawning habitat and to ban the harvest of shellfish from contaminated parts of the estuary. Now the tribe is monitoring rivers on its own. ln the near future CMOP plans to install a sensor that can be monitored remotely, and to train people to read and interpret the data.
Community-inspired research often produces a ripple effect of unforeseen results. ln this case, inclusion of Elders in the design and implementation of the project produced large scale buy-in from community members at all age levels. Consequently, in a village where traditionally students did not think about education beyond high school, we have had two students attend college, two students attend trade school, five students receive scholarships, and eight Native interns conducting science or science education in the community. And, given the low numbers of Alaska Natives pursuing careers in science, we find those numbers to be remarkable.

No Fooling: Exploring the Nature of Responsibility, Progress, Success, and Good Work
How we answer a challenge raised over half a century ago regarding the way we handle the blessings of nature will go a long way towards determining our future.
by Peter Hayes
In the roughly 10,000 years since members of our species first began to call the Pacific Northwest home, many good questions have been asked. Of all that have been posed, one continues to stand out as the most important. In 1938 during a noontime luncheon address to a group of prosperous citizens in Portland, Oregon, the thoughtful, worldly generalist, Lewis Mumford asked this question: “I have seen a lot of scenery in my life, but I have seen nothing so tempting as a home for man than this Oregon country… You have the basis here for civilization on its highest scale and I am going to ask you a question which you may not like… Have you enough intelligence, imagination, and cooperation among you to make the best use of these opportunities?”
Though he spoke to one group of people in reference to the future of one region, the question applies equally well to our entire species and our total habitat — this planet — “do we have the qualities necessary to successfully live here for the long haul?” That is the most important question in the world. The only answers which matter are those expressed through actions, not words. And what do the consequences of actions taken since Mumford’s 1938 question say about our success? There is certainly good news in the form of the development of a more crash resistant economy, a country and world which may have made progress toward the challenge of judging people by the quality of their character instead of the color of their skin, and the imagination, endorsement, and enforcement of laws which help the powers of care, cooperation, and foresightfulness get the upper hand on the powers of selfish, shortsighted greed trying to turn our commonwealth into their personal wealth.
But overall the evidence of actions taken, and not taken, since 1938 indicate that our answer to Mumford’s question is: “no, we don’t yet have the qualities necessary to successfully live here. Our perceptive abilities, values, and ethics have not yet evolved in the ways that they must in order to develop and use those qualities”.
If meeting the challenge is a matter of fundamental survival, why haven’t we done it? If we are clever enough to pull off such feats as walking on the moon, splitting atoms, and cloning creatures, why not attend to our most basic survival? The answer is that we choose to fool ourselves. Fueled by the powerful forces, including the omnipresent media and our systems of schooling, we fool ourselves in four main ways. Progress toward meeting Mumford’s challenge — our most basic responsibility — depends on recognizing and correcting the ways that we’ve been fooled and continue to fool our children.
The fooling happens in how too many of us answer these four questions: 1) What is success?, 2) What is our greatest challenge?, 3) What is the basis for our decision making?, and 4) What are schools for?
What is Success?
One major reason for our continuing failure to meet — or even acknowledge — Mumford’s challenge is that for the majority of our species the challenge is not seen to be important enough to even pay attention to; for many, there is no connection between our personal yardstick of what it means to be a successful person and progress toward the challenge. Our systems and competitive instincts program us to be amused and preoccupied by other challenges and measures of success — accumulating more money than we need, proving that we are better than other people — whether on the sports field, in the classroom, boardroom, stock exchange floor, or battlefield, and basing our identities and sense of success on the acquisition of power, prestige, and comfort — on what we can take instead of what we choose to give. So, much like the highly capable student who flunks a course because she just didn’t choose to try, the first reason we continue to not meet Mumford’s challenge is that too many of us continue to be fooled into believing that success is measured by actions which take us further from meeting the challenge instead of toward it. Tellingly, Mumford prefaced his question to Portland’s City Club with the caveat that he had a question which his audience probably would not like. Wasn’t this because it presented — to people who already saw themselves as successful — an alternative, ultimately more important, measure of success, which if recognized, stood to threaten and/or limit their accepted notions of success?
What is the Challenge?
As a teacher, I owe thanks to my students for helping me recognize the second way that we fool ourselves. Year after year class discussions devolve into a familiar debate over which of the challenges on humanity’s plate is most important and deserving of our attention and energies. Here is a sampler of predictable excerpts: “Yes, I know that all of the problems with the environment, such as saving the salmon, are important, but you’ve got to realize that we have to look out for the well being of our own species first; people are starving and that must be our top priority.” Or “These efforts to help people learn to treat each other well, and to solve environmental problems like global warming are important, but we have to be sure to do nothing which might threaten quarterly profits and harm the economy; if we don’t have a strong economy, things will fall apart”. They have learned what they have been taught — and been fooled, just as I was fooled. We have inherited a flawed conceptual model which is based on the assumption that our species faces three, competing challenges: the challenge of people learning and choosing to successfully live with one another, the challenge of humans learning and choosing to live within the limits of what the land can provide, and the challenge of learning and choosing to develop an economic system which can endure over time. I fell for it; conclusions such as Aldo Leopold’s: “We end, I think, at what might be called the standard paradox of the twentieth century: our tools are better than we are, and grow better faster than we do. They suffice to crack the atom, to command the tides. But they do not suffice for the oldest task in human history: to live on a piece of land without spoiling it.” fooled me into the mistaken belief that one of the three competing challenge was paramount. I now see that from birth my culture conditioned me to see myself as positioned in the center of a triangle, with compelling, competing, and insistent voices from each corner vying for my attention. Across from Aldo’s siren call come the words of Martin Luther King Jr. and others, such as “We must either learn to live together as brothers or die together as fools.” And from the third corner come the powerful economic cautions of Alan Greenspan, Wall Street, and the WTO advising that without a functioning economy we have nothing. After investing twenty five years of my working life in the wholehearted, and often zealous, service of one of the three challenges — helping people learn and choose to live within the limits of what the land can provide – I have come to see that I was wrong because my work has been based on a flawed conceptual model of the real nature of the challenges. Aldo was right, but he was also wrong; King was right, but he was wrong; Greenspan is right, but he is wrong.
While each is essential, none is in itself sufficient. An economy dependent on the degradation of land or people will never succeed; a healthy land community depends on a functional economy and healthy human community; and humans cannot resolve their differences as long as the ecosystems and economies on which they depend are in disarray. As Jared Diamond described in a post September 11th letter to the Washington Post: “If a dozen years ago you had asked an ecologist uninterested in politics to name the countries with the most fragile environments, the most urgent public health problems, and the most severe overpopulation, the answer would have included Afghanistan, Burundi, Haiti, Iraq, Nepal, Rwanda, Somalia, Yugoslavia, and Zimbabwe. The close match between that list and the list of the world’s political hot spots today is no accident.” Though the world around us continues to do its best to fool us into seeing three competing challenges, the evidence from a careful look at how the world really works convinces me that these are not three challenges, but one — building communities which can survive and thrive indefinitely. For me, the competitive triangle model has been replaced by an interdependent, cooperative circular model of three links of chain. Healthy communities depend on meeting the challenges represented by each link, and our success is only as strong as the weakest link.
Progress depends on each of us learning to let go of our drive to see our highest priority corner or link prevail over the other three (think Earth First, WTO), and instead develop a higher commitment to the whole of being a citizen and community member than to any one of the links. Ironically it seems that the longer and harder we continue to push on our chosen corner of the competitive triangle model — as well meaning as we may be — the less likely we are to make progress toward any of the challenges. Success depends on turning all of our environmentalists, human rights activists, and economic development enthusiasts into just plain citizens — knowledgeable about and committed to all three links of the chain. These people fit into Wallace Stegner’s notion of choosing to be “stickers” instead of “boomers”, and follow the advice of Gary Snyder and others that one of the most radical — an useful – things we can do is to stay put.
What is the Basis of Our Decisions?
The third way that many of us continue to fool ourselves is pretending that the basis of our decisions can reasonably shift if distanced by time and/or space. When reduced to the most local scale, our moral evolution, as a species, has progressed toward basing an increasingly percentage of our actions on what is right to do as opposed to what we have the power to do.
Even if I am bigger and tougher than my two eating mates, I don’t eat more than my third of the pizza because that is the right thing to do; sharing a common pasture with other farming families, I choose to graze only as many cattle on it as the land can provide for, because that is the right thing to do; even if certain investments could be unusually lucrative, I choose not to invest in them because they are bad for the community. Each of these represents a choice to base decisions on ethics instead of power. In contrast to the progress we have made in what might be called moral evolution, we continue to fool ourselves with arbitrary blinders and barriers in terms of what we consider to be the domain of ethics and what is the domain of power.
Curiously something which is based on ethics when close to us in space or time, can slip back to being based on power when removed to greater distance. An example is the land use choices of forest products companies based in the Pacific Northwest. When operating within the United States the company uses a set of land use practices which their full page newspaper ads tell us are shaped not by laws, but by an abiding, ethically based commitment to land stewardship. Yet when the same companies transfer capital from domestic investments to forestry in other countries, their treatment of land is much less careful and, in the absence of land use laws in places like Russia, the basis for company decision making apparently shifts from ethics to what they have the power to do. Similarly, though I might buy a shirt made using child labor paid at unreasonably low rates — if it came from a very distant place, I would refuse, on ethical grounds, to eat at a local restaurant whose existence and profits depended on similar human abuse. Though a fisher would choose for ethical reasons not to steal fish from the hold of a fellow fisher’s boat moored alongside of his, he sees no ethical problem with overfishing a species, such as Atlantic Cod, to commercial extinction, which is effectively stealing fish from the holds of the fish boats of his children and grand children. Why do so many of us continue to fool ourselves into believing that our responsibility for ethical decision making decreases in proportion to how distant and anonymous the consequences become in space and/or time? Isn’t a consequence a consequence, no matter where and when they happen?
The Work of Schools
Mumford’s question — do we have the characteristics necessary to successfully live here — begs a preceding question: what characteristics are most important to us as we seek to meet the challenge?
Though he suggested intelligence, imagination, and cooperation, what would be your top ten essential attitudes, skills, and habits? What letter grade would you give the success of the five schools closest to your home at developing these characteristics in their students? What limits their success in doing this? The schools in my community are failing in this most important responsibility because they don’t recognize it as being their responsibility and are never held accountable for success. Instead, their missions, parental pressure, and deadening effect of school reform standards focus their attention and resources on maintaining and increasing students’ upward mobility — or put more bluntly – using the fair winds of competitive instinct to train good predators. Because of this, the final of the four barrier between us and rising to meet Mumford’s challenge is that too many of us fool ourselves into believing that our schools can be considered to be successful when they continue to put a disproportionate emphasis on preparing students to take/pursue personal gain — instead of developing in students the readiness to give in proportion to what they take, which is the measure of responsible citizenship. This status quo of schooling is a road toward diminishing returns because the pursuit of individual gain at the expense of our commonwealth leaves a dwindling world to be upwardly mobile in. We will know that this barrier is behind us when our schools are as, or more, effective at encouraging moral evolution and developing the characteristics of citizenship as they are in preparing students for upward mobility.
I was born into a world where the imbalance between what people asked of our communities and what those communities had the capacity to provide led to progressive erosion of community health and vitality. Though the decline continues, I am optimistic that within my lifetime it is possible for us to turn the corner by reconciling what our species demands with what the systems can sustainably provide. Every day I become increasingly convinced that the key to success is waking up to the four crucial ways that we fool ourselves and continue to fool each succeeding generation. What makes me hopeful is that when you look closely, in the right spots, it is easy to find, learn from, and be inspired by many remarkable examples of work that are successfully beginning to rebuild community vitality. Their success is the result of choosing to end the foolishness by redefining progress and success, re-envisioning three competing community challenges as one challenge, expanding the universe of ethical responsibility, and reshaping schooling to acknowledge that educating for responsible citizenship is our highest responsibility.
Among all of the candidates proposed as yardsticks for a successful life – educational pedigree, net worth, level of influence — is not the ultimate measure of our value and good work the degree to which we help equip our culture and its children to answer “yes” to Mumford’s challenge?

Can School Gardening Help Save Civilization?
(An Essay in Four Parts)
by Carter D. Latendresse
The Catlin Gabel School
This paper is an argument for gardening in schools, focusing on two months of integrated English-history sixth grade curriculum that explores the relationships between a number of current environmental problems—notably hunger, water scarcity, topsoil loss, and global warming—and the land-use practices that led to the downfall of ancient Mesopotamia. This paper suggests that world leaders today are repeating some of the same mistakes that caused desertification to topple the Sumerian empire. It then explains how our sixth grade class explores solutions to the existing emergencies by studying Mesopotamia, ancient myth, gardening, and contemporary dystopian fiction. Finally, this paper posits a new cosmology that might help to remake western civilization, saving it from the threat of present-day ecological crises.
Part I: Four Enduring Understandings
Part II: Nine Reasons for a Garden
When we present the following nine reasons for our study of Mesopotamia in the garden, we do so in the problem-solution format so that our eleven and twelve year-olds do not feel overwhelmed by the quandaries of history, society, and science, and so that they might exercise their innovation and collaboration during their civilization-creation group work, thereby feeling efficacious while creating solutions for what ails us today. I will therefore present the nine reasons here in that same problem-solution fashion.
The Water reason
Problem: In his landmark book When the Rivers Run Dry, Fred Pearce (2006) tells the story of the Sumerians in the Fertile Crescent 7500 years ago, how they build the first giant irrigation systems using river water from the Tigris and Euphrates. They dug large canals and erected gigantic levees to protect themselves from the spring floods. However, the world’s first writing, cuneiform, done on clay tablets, notes that 3800 years ago their once great farm system was failing, the southern Mesopotamian “black fields becoming white” and “plants choked with salt” (Pearce, 2006, p. 186). The empire had to switch from wheat to barley, which is more tolerant of salt than its predecessor. The barley eventually failed as well, as “the salt chased civilization through Mesopotamia as mercilessly as any barbarian horde” (Pearce, 2006, p. 187). Pearce goes on to compare Mesopotamia to Angkor Wat in Cambodia, noting that great ancient civilizations emerged in environments where controlling the water was the highest priority. These ancient worlds, sometimes referred to as hydraulic civilizations in class, are unlike the more modest and oldest continually settled city of Jericho in Palestine, which has sustained farming on a smaller scale for 9000 years due to a spring producing 20 gallons a second (Pearce, 2006, p. 185). The grander cities of Mesopotamia were vulnerable to desertification, climate change, and silt built up in their waterways. Jericho, on the other hand, supplies a sustainable, if less impressive because less massive example for future generations.
What do the water problems of Mesopotamia, the students want to know, have to do with us today in Portland, Oregon, where it seems to rain for eight straight months every year? According to Maude Barlow, co-founder of Blue Planet Project, the National Resources Defense Council (NRDC) has published the alarming statistic that forty U.S. states are currently threatened by water scarcity. Not only are we vulnerable nationally to water shortage, but worldwide, lack of clean water is the leading cause of childhood death (Barlow). When pondering these threats, one begins to see that the misuse of water has continued unabated from the ancient world to present day. Take, for example, the wastefulness of the typical meat-based diet. “To produce just one pound of beef takes thousands of gallons of water. . . and this is [in] a world in which two-thirds of all people are expected to face water shortage in less than a generation” (Lappé & Lappé, 2002, p. 15).
Solution: The Sierra Club (2012) has a website on water conservation that we share with our students, asking them to think about using some of the strategies presented there in their own homes. Strategies include installing a low-flow showerhead, replacing the lawn with drought resistant plants, using drip irrigation in gardens rather than sprinklers, and watering with saved gray water. (Top Tips section, para. 13, 20, 22, and 26; and Other Considerations section, para. 2).
Here on campus, we have installed drip irrigation in our raised beds in order to reduce water evaporation. We have also installed an instructional rain barrel off of our cob oven roof in the garden that waters a tulip and lily bed so that students can see a water reclamation project in action.
The Dirt reason
Problem: In his article “Our Good Earth,” Mann notes that “today more than six billion people rely on food grown on just 11 percent of the global land surface,” while just “a scant 3 percent of the Earth’s surface [is] inherently fertile soil” (2008, p. 92). Clearly, in order for the world to feed itself, it has to conserve the living, fecund, very thin skin of this planet.
In the first and still most thorough study of global soil misuse, scientists in the Netherlands at the International Soil Reference and Information Centre (ISRIC) estimated in 1991 that humans have degraded, in ways described in Part I of this essay, 7.5 million square miles of land, an area that equals the U.S. and Canada combined (Mann, 2008, p. 90). Food riots have broken out every year over the globe for the past decade, due mainly to this degradation of the world’s soil.
Not all hope is lost, however. Rattan Lal, a soil scientist at Ohio State University, says that amending the world’s damaged soils with vast amounts of carbon can address several issues simultaneously. “Political stability, environmental quality, hunger, and poverty all have the same root. In the long run, the solution to each is restoring the most basic of all resources, the soil” (Mann, 2008, p. 90). Save the soil, put the people back to work, and allow them to feed their families—these are the recommendations of the ISRIC.
Solution: To preserve soil, water, and to reduce global warming, Bill Benenson’s (2009) movie Dirt, in a more prescriptive way than the ISRIC,recommends the following: Farm a variety of crops organically rather than monocropping with herbicides and pesticides, which is typically done in conventional agriculture. Further, we should fertilize with cow dung and compost rather than with nitrogen-heavy chemical fertilizers. The film also recommends collecting and trading seeds, planting trees, employing people to green urban spaces, joining a CSA for vegetables, and shopping for local seasonal produce at farmer’s markets when possible.
Here on campus, we show our students the film, and we harvest organic vegetables from our garden for our lunch salad bar, later composting back into our garden. The circularity of this system allows us to preserve the health of our soil and to teach invaluable lessons on soil conservation.
The Bee reason
Problem: During an interview on You Tube with the director Jon Betz and producer Taggart Siegel (2010) of the movie Queen of the Sun, Jonathan Kim (2011), the interviewer, points out that Colony Collapse Disorder (CCD) sweeping the bee world over the last five years has profound consequences for humans, as 70% of human food comes from pollination by honey bees, including broccoli, apples, soybeans, citrus, and grapes (Kim, 2011). Queen of the Sun suggests several factors for the cause of CCD, from viruses to funguses to pesticides to mites to monocropping to giving the bees antibiotics. Scientists do not have a consensus; however, early data suggests that trucking bees to pollinate monocultures, such as almond orchards in California and apple orchards in Oregon, weakens bee hives because orchards lacking biodiversity draw an inordinate level of pests, which prompts the orchardists to spray immense amounts of pesticides, which the bees ingest, and which weakens to bees’ immune systems. Michael Pollan states in the film that this industrialized farm system eventually degrades into monocrop deserts, contributing to CCD.
Solution: We need to keep bees on biodiverse gardens, farms, orchards, and campuses across the country, to normalize the presence of honeybees and to help children to distinguish between the honey bee and the much more aggressive wasp or yellow jacket, which are drawn to our picnics and our lunch meats.
The sixth grade team has been working with a Portland-based beekeeper to keep two hives in the Catlin Gabel School apple orchard to pollinate the trees on campus and to raise honey for our cafeteria. Learning about bees by interacting with them on a biodiverse campus is an important way for students to mitigate CCD and to ensure the continuance of pollination by honeybees.
The Population reason
Problem: There were 36 million people in Europe in 1000; 45 million in 1100; 60 million in 1200; and 80 million in 1300. In three hundred years, the population of Europe more than doubled, which required more land to be cleared for food production. This was made possible by a relatively warm climate across Europe from 800 to 1200. Forests originally covered 95% of western and central Europe, but the need to feed the burgeoning population reduced the forests to about 20% (Ponting, 1991, p. 121).
World population first reached one billion in about 1825, and it had taken 2,000,000 years to do so. That population reached two billion by about 1925. The third billion only took 35 years, in 1960. The fourth was added by 1975. The jump from 4 to 5 billion only took another 12 years (Ponting, 1991, p. 240). If one looks at a graph of world population from 1700-2000, one is immediately struck by the fact that it resembles, in an eerie but understandable way, the dramatic spike in Earth’s surface temperature during that same historical period. The fact of modern global warming was first brought to the world’s attention by Houghton et al. (2001) with the publication of their Intergovernmental Panel on Climate Change’s (IPCC) Third Report entitled Climate Change 2001—Scientific Basis. Most people remember Michael Mann’s “hockey stick” graph of 20th century climate change from Al Gore’s (2006) documentary film An Inconvenient Truth (Bender, Burns, and David), showing how the 1990s were the warmest decade on Earth in one thousand years. Mann’s graph was peer reviewed by the IPCC and used as a basis for Figure 1, “Variations of the Earth’s Surface Temperature over the Last 140 Years and the last millennium” in the 2001 report (Houghton et al., 2001, Summary for Policy Makers section).
What, one might wonder, does population have to do with global warming? The common denominator here is oil, which was first drilled in the U.S. in 1859 in Pennsylvania. Oil helped the human species to triple in one century from two to six billion. Over a billion acres of land across the globe was brought into food production between 1920 and 1980 (Ponting, 1991, p. 244). Once the land was planted and harvested, the international food trade blossomed with two oil-backed innovations: the first being ocean and railway transport, the second being refrigeration. “The nineteenth century marked the end of several thousand years of largely self-sufficient agriculture . . . and the transition to an era where much of the food consumed in the industrialised (sic) countries was imported” (Ponting, 1991, p. 245). At the same time, greater mechanization of tilling, harvesting, storage, and transport led to a sharp decline in the number of farms. In the U.S. alone, farm numbers fell from 7 million in 1930 to 3 million in 1980, while over half of the produce was produce grown and distributed by just 5% of the total number of farms (Ponting, 1991, p. 246). The lesson here is that with the sharp increase in world population came a correspondingly steep rise in the fossil fuels used to feed that population as well as an absurdly precipitous decrease in the number of people farming sustainably in a biodiverse way for subsistence. Every year we add approximately 70 million more people to Earth, which requires, given our industrial food economy, greater inputs from machines, fertilizers, and pesticides—all oil-based, all contributing to land, air, and water degradation and global warming (Elbel & Stallings, 2009).
Solution: The challenge remains to feed a ballooning world population without polluting the world that needs to feed that population. There isn’t one answer here. Intersecting solutions, as proposed by the National Geographic Society’s (2012) Eye in the Sky project, include the following: One, preserve the soil by rotating crops and farming organically with a variety of crops on each farm, which can reduce the need to clear more woodland for agriculture. Two, contour plow, which reduces water-polluting runoff. Three, governments should limit or ban the use of DDT as an insecticide because of its spread through food chains. Four, affluent nations should eat less meat so that the grain and water that are given to cows can be redirected to humans who are hungry and thirsty.
Here at school, in addition to sustainability, another one of our mission objectives is global education. To that end, the fifth grade teachers teach the book What the World Eats, by Faith D’Aluisio and Peter Menzel (2008). Their photo-documentary allows students to compare and contrast the food that twenty-five families in twenty-one countries purchase and eat in one week. The text and teachers highlight the connections between family income, family size, geography, food availability, and diversity in diet. As a result of this study, students begin to internalize the connections between their families and the families of a billion others across the globe.
The Climate change reason
Problem: The United Nations Intergovernmental Panel on Climate Change (IPCC) has been telling us for twenty years that climate change is real, that the planet is getting hotter, that this warming causes extreme weather events, and that global warming, especially in the last hundred years, is human-induced (Henson, 2006, p. 273). Though there had been some spurious anti-scientific debate over global warming ten years ago, in their 2007 IPCC report, editors Pachauri and Reisinger confirmed, through further research, that this century’s precipitous spike in global warming is due to human greenhouse gas emissions (Summary for Policymakers Section; Subsection 2: Causes of Change).
Last winter, PBS News Hour (2011) released a slideshow online entitled “Weather’s Dozen,” which presented photographs of twelve extreme weather events in the U.S. during 2011, including tornadoes, heat waves, droughts, and floods. Each of the disasters exceeded a cost of one billion dollars in damages. The slideshow also presented a bar graph comparing financial costs of these disasters from each year over the last three decades. One sees that on this last slide, the National Oceanic and Atmospheric Administration (NOAA) reported that 2011 was the costliest year ever recorded for extreme weather damage (PBS Newshour, 2011, slide 13).
The planet’s climate has changed, and each year floods, tornadoes, and heat waves strike more and more people, which also, in a cruel irony, ravage the world’s nonrenewable fossil fuel energy sources. In the last two years, weather, plate tectonics, and geography have conspired to join forces in disasters involving our three main energy sources: the BP oil spill of 2010, the Upper Big Branch Coal Mine in West Virginia in 2010, and the Fukushima Daiishi Nuclear Power Plant in 2011. Scholars note that as long as people seek nonrenewable energy sources in hard-to-get-to places, given the unpredictable and increasing nature of extreme weather events, that more disasters like these are inevitable. Today, oil companies have to tread into environments, like the Gulf of Mexico or the Arctic Circle, that are unstable since they are in regions that host either hurricanes or drifting ice sheets. Acknowledging the risks, some analysts have called this energy policy “Energy Extremism,” since more disasters like the BP oil spill will inexorably follow with energy strategies that require drilling in environmentally unstable regions (Klare, 2010, p. 30-31). The world’s fossil fuel markets and the governments that court those markets seem oblivious to science and history—lessons that teachers and middle school students find mind-boggling.
Solution: I present Tim Flannery’s (2005) book We Are the Weather Makers for my students because it lays out both the threats and a wide variety of solutions to global warming that our students and school community might follow. Our goal as sixth grade teachers is to move our students from ignorance to knowledge, from hopelessness to compassionate action. Some of Flannery’s extensive suggestions include the following: buy a hybrid car or take public transportation; buy Energy Star appliances; install solar panels on roofs; insulate homes well; change all light bulbs to compact fluorescent light bulbs; plug all electrical devices into power strips, and then turn off the power strips at night; switch plans with power companies to draw from renewable energy sources; recycle; don’t use plastic bags; resist buying products made with petrochemicals; eat locally, seasonally, and organically; turn off the tap when brushing teeth; use recycled paper; and cancel junk mail.
Here at Catlin Gabel School, our Facilities Director sends out monthly “Energy, Waste, and Water Reports” that detail electricity use, gas use, and water use, along with landfill by weight, recycling by weight, and compost by weight for the buildings on campus. We teachers and students are therefore able to chart our contributions to global warming throughout the year, and we are all aiming for zero waste and reduced carbon footprints.
The Nutrition reason
Problem: The book Forks Over Knives alerts us to the fact that“two thirds of adults [in the U.S.] are either overweight or obese, and obesity rates for children have doubled over the last thirty years” (Stone, 2011, p. 4). Obesity, therefore, has been rightly identified as a national health crisis, but what is perhaps less well known is that certain populations are at greater risk than others. The obesity epidemic is complicated, but the inner-urban neighborhood eyeball test can be as instructive as the arcane spreadsheet of a distant PhD when analyzing this issue.
What we see when visiting inner city neighborhoods in Portland is corner alcohol stores and fast food chains, not grocery stores offering nutritious fruits, vegetables, and whole grains. What is more, the poor don’t have places to play—very few parks or community centers. Further, in the inner city schools, PE is being cut, while the stories of unhealthy food in the public schools are ubiquitous. How exactly does childhood obesity connect to poverty and to ethnic background?
Poverty is racial, as a 2011 study of poverty by race and ethnicity in Portland showed. A staggering 52% of African American children live in poverty in our city, followed by 34% of Hispanic American children, 15% of Asian American children, and 10% of White children (Castillo & Wiewel, 2011). Noting that many of these children living in poverty also live in neighborhoods without farmer’s markets and grocery stores, one can also easily surmise that nutritional food and healthy diets are not as accessible to non-white Portland children. For our purposes of looking at food and gardening, we can conclude that not only is poverty racial, so is childhood obesity (Boak, 2007). Recent studies that take into consideration ethnic background in the U.S. find that Hispanic, Native American, and African American populations have higher rates of childhood obesity than Asian Americans and those self describing as White (Caldwell, 2009, para. 1-2).
Clearly, when we start looking at nutrition in our classrooms, our lenses have to expand to include ethnicity, income, demographics, and neighborhoods. That said, the fact also remains that all American children, regardless of ethnic background, street address, or family income level, are at risk of obesity and type II diabetes. There is something in our culture that is funneling our children toward these unhealthy ends.
Solution: The authors of Forks Over Knives tie together nutrition, cooking, the ethical treatment of animals, and greenhouse gas reduction strategies, and they have a simple message for improving our nutrition: eat a vegan diet that is plant-based and consisting of whole-foods. The closer the plant is to its original state in nature, the better. Their vegan diet, they claim, will erase obesity without compromising daily caloric, nutrient, or protein requirements. What is more, a transition to a vegetarian diet free of all meat, fish, dairy, and eggs will help to heal the soil, water, and climate ills facing our world. The authors point out that, at the current rate of population increase, Earth will hold nine billion people by 2050. The majority of those people will be born in China, India, and Africa, and as their incomes rise, they will eat more meat, cheese, and milk products. “The United Nations’ Food and Agriculture Organization (FAO) predicts that meat consumption will more than double by 2050, and milk consumption will grow by 80 percent during that period” (Stone, 2011, p. 35). While advocates of animal-based proteins argue that these increases are logical and beneficial for people’s health, the fact also remains that eating a variety of vegetables, legumes, unrefined grains, seeds, and nuts can supply a person’s daily protein requirements (Mangels, 1999). Another more obvious argument against eating more meat and drinking more milk in an ever-enlarging factory farm model are the deleterious effects upon soil, water, and climate.
The United Nations has found that farm animals create 20% of all human-induced greenhouse gases (carbon dioxide, methane, and nitrous oxide). However, “if every American simply reduced chicken consumption by one meal per week, the carbon dioxide savings would be equivalent to removing 500,000 cars from the road” (Stone, 2011, p. 40). People can also help to conserve water by eating less meat. The April, 2010, National Geographic magazine special issue on water has created a poster entitled “Hidden Water” that shows that “a human diet that regularly includes meat requires 60 percent more water than a diet that’s predominantly vegetarian” (McNaughton et al., 2010). In addition to water use, raising animals for food also “accounts for about 55 percent of soil erosion” (Stone, 2011, p. 39). To recap: we could reduce obesity and greenhouse gas emissions, while also preserving topsoil and water resources, if we ate less meat and animal products. What is stopping us?
On campus, our Director of Food Services regularly comes into our sixth grade classroom to teach lessons on growing, purchasing, and cooking with local produce. These classes are favorites among our students, as they get to do what all sixth graders want to do in school: eat! The sixth grade is also a leader class on campus for growing organic fruits and vegetables for our daily salad bar, enacting the principles of good nutrition, topsoil preservations, and water conservation.
The Globalization of food reason
Problem: The opening words of the movie Food, Inc. (2008) sum up the current industrial food system this way: “The way we eat has changed more in the past 50 years than in the previous 10,000, but the image that’s used to sell the food is still the imagery of agrarian America” (Kenner & Pearlstein).There are 47,000 products in modern average American supermarkets, which offer food out of season from all over the globe, encouraging the delusion that the world does not have seasons, that food is not tied to the earth, the weather, or to the seasons (Kenner & Pearlstein).The reality is that our current industrial food system is a factory, not a farm, with a small handful of multinational corporations controlling food from seed to plate. When the global food system is scrutinized in terms of global warming, it is unmasked as a main polluter: “Our food production—our fossil-fuel driven industrial model—[is] one of the biggest culprits, responsible for about one-fifth of human-caused greenhouse-has emissions” (Lappé & Lappé, 2002, p. 19-20).
Let’s look at the situation with chickens. Three or four companies control the beef, chicken, and pork in the U.S., and their goal is the same product every time. The chicken conglomerates today house chickens cheek to beak in giant feedlot barns without light, where they are unable to move around, and they are given antibiotics to stave off the eventual sicknesses that come from poor diet, nonexistent physical activity, and standing in their own feces. All that said, the chickens are bigger now in less time than they were 50 years ago (Kenner & Pearlstein). The same scenario outlined here could describe the life of most cows and pigs in the U.S. The meat we are eating from these factory farms is of inferior quality, and the lives of the animals are not being honored in even this most basic of humane ways.
Other companies, such as Monsanto, are busily engaged in seeking to gain control of the world’s food sources via genetically modified seeds. It is true that Monsanto’s genetically modified (GM) seeds helped millions avoid starvation in the 1970s, especially in India, during the so called “Green Revolution,” when high-yielding varieties of rice and wheat, along with tons of NPK chemical fertilizers, gave a few decades of bumper crops. Those same GM seeds and fertilization practices, however, have stripped micronutrients from Indian soil, as the high-yielding varieties were also ravenous, drawing up zinc, manganese, iron, and other micronutrients that healthy soil need to support crops. What is more, decades of dumping chemical fertilizers and overwatering have also poisoned the soil with toxic levels of fluorine, aluminum, boron, iron, molybdenum, and selenium (Shiva, 2008, p. 102). Monsanto and other GM companies are responding by increasing their lab technicians’ time to come up with new seeds and fertilizers that they believe will feed Earth’s swelling population in the 21st century.
The promise established during the early years of the Green Revolution has faded into a bizarre world of the global food economy, where companies that make herbicides are selling us food seeds, and where we are industrializing the food at the cellular, genetic level. Let’s go back and trace the history to figure out an alternate path.
In 1970, Monsanto created Roundup. In 1980, the U.S. Supreme Court extended patent law to cover “a live human-made microorganism” (Barlett & Steele, 2008, p. 158). From 1980, when there were zero genetically modified crops being grown in the U.S., to 2007, the amount of land planted with G.M seeds rose to 142 million acres planted in the U.S. and 282 million acres across Earth (Barlett & Steele, 2008, p. 160). In addition, during the 1980s, Monsanto began buying seed companies. Today, Monsanto is the largest seed company in the world (Barlett & Steele, 2008, p. 160). In the 1990s, Monsanto seized upon the opportunities opened by the 1980 Supreme Court case and began patenting life. The Green Revolution turned into the Gene Revolution. Today Monsanto owns 11,000 patents (Butler & Garcia, 2004). Deborah Koons Garcia (2004), director of the movie The Future of Food, believes that the company knows that whoever controls the seeds, controls the food. She speculates that Monsanto does not want biodiversity or food diversity; rather, she says, it wants to buy then patent all the seeds, then take those seeds off the market. Then they will produce only their Monsanto Roundup Ready seeds. Other analysts have come to the similar conclusions about this company, though we as teachers present these conclusions as theory while withholding the company name to protect community members who might work there.
From our perspective in the sixth grade, we are less interested in eviscerating certain companies than discussing farming practices as they relate to Mesopotamia. Therefore, we point out that “farmers who buy Monsanto’s Roundup Ready seeds [again, we withhold the company name] are required to sign an agreement promising not to save the seed produced after each harvest for replanting, or to sell the seed to other farmers. This means that farmers must buy new seed every year” (Barlett & Steele, 2008, p. 158). Such a practice of agreeing to deliberately let seeds go to waste reverses food growing practices since the founding of the first towns in the Fertile Crescent 9,000 years ago.
The connections between Monsanto, biodiversity loss, dying local economies, and poor nutrition are also becoming more evident, especially upon acknowledging that 70% of processed food—with its high salt, fat, and high fructose corn syrup levels—has a GMO in it. Perhaps not surprisingly, given the army of lobbyists that agribusiness has on Capitol Hill, it’s also against the law to label GMO foods in the U.S. (Kenner & Pearlstein, 2008).
Solution: Knowing that the leading manufacturers of carbon dioxide emissions come from transportation and coal-burning power plants for electricity generation (Flannery, 2005, p. 23 and 62), Vandana Shiva’s indictment of the global food industry that ships temperature controlled vessels around the world is rigorously logical. The solution we tell our students is to eat whole foods, not processed foods; local foods, not food from thousands of miles away; organic foods, not GMO food products; seasonal foods from the Northwest, not bananas from Ecuador in the wintertime. We realize that the children do not purchase the food that their families eat, but if they were to enact these practices, not only would they be allowing farmers to return to more healthy food production methods, they would also be encouraging millions of farmers across the world to save seeds and feed their families and communities with locally grown, organic, healthy food.
In their book Animal, Vegetable, Miracle, Barbara Kingsolver and her family (2008) recount a year of living in Kentucky eating in this way, which necessitated learning to can and pickle, eat more roots in winter time, and reach out to trade with neighbors who raised the apples, beef, and lamb that her own family could not. Farmers and writers like Wendell Berry have been modeling this practice for years, and we encourage our students to return to it, whenever possible.
On campus we teach a Sweetness of Apples lesson (Reed & Stein, 2009) from the PBS series The Botany of Desire, based upon the book by Michael Pollan (2002). We harvest apples from our own orchard, and then purchase some other organic northwest varieties from a local market, New Seasons, which lists, on their produce bins, the grower name and orchard location. Students not only connect their diet to their campus, they can easily calculate the food miles accrued for the morning lesson.
The Oil reason
Problem: As sixth grade teachers, we recognize the urgency and our responsibility toward our students. One of my objectives during the Mesopotamia unit is explore two closely aligned myths: 1. Our world can support consistent and unlimited economic growth, even when China and India begin using the same amount of energy, per capita, as the U.S.; and 2. Oil, coal, and natural gas use can continue in the same way.
In order to assist the deconstruction of the myth of unlimited economic growth, I show Paul Gilding’s (2012) TED talk entitled “The Earth Is Full.” Gilding points out that we would need one-and-one-half earths to provide us with the available fossil fuels to maintain our energy usage for our current global economy.
The second myth is trickier to tease apart, as our daily lives seem to argue for its validity. I woke up in my heated house, had a toasted bagel baked across town, took a hot shower, and then drove my heated car on well-lit streets to a heated, well-lit school. Where is the fossil fuel shortage?
I tell my students that many scientists and journalists, like Kenneth Deffeyes (2005) and Tim Appenzeller (2004), believe that “peak oil,” first predicted by M. King Hubbert (1969, p. 196), is upon us. I explain to my students that since oil is a non-renewable, finite resource, there is day called “peak oil day” when oil producers reach their maximum amount in history they can extract from the ground and refine. That day is peak oil day, and every day after begins the decline of oil on this planet until its eventual depletion. The International Energy Agency in Vienna, Austria, notes that 2006 marked the all-time high of 70 million barrels a day of oil using conventional crude oil production methods (Inman, 2010, para. 2-4).
Other writers, such as James Kunstler (2005), draw far-reaching conclusions from this concept: “The oil peak phenomenon essentially cancels out further industrial growth of the kind we are used to” (p. 28). What Kunstler means is that because our global economy is predicated upon the reliable supply and use of oil and gas, and because that supply will begin decreasing until it is gone in the near future, our global economy as we know it is, at best, destined to have to change, and, at worst, doomed. Kunstler goes on to show how the billions of people in the recently developed nations who now seek the automobiles, electricity, and materials goods that the EU and USA have had for the last forty years will push global warming, biodiversity loss, and biosphere pollution to their breaking points.
We’re smart, though, many argue. Scientists will figure out how to solve these problems. Again, Kunstler doesn’t think so. There will be no one technological fix, he says, to the intersecting problems of overpopulation, global warming, and the end of peak oil. Even with the combination of compatible technologies such as carbon sequestration, solar power, wind power, geothermal power, and hydroelectric power, the net energy output cannot match our current needs in the U.S., to say nothing of the energy needs of the rest of the world. He takes nuclear power off the table as foolhardy and unsustainable, and given the events of last spring in Japan as chronicled by BBC News online (2012), his omission seems wise (Kunstler, 2005, chap. 4). Noting the irony that non-fossil fuel energy systems, such as wind turbines, require burning more fossil fuels to produce and maintain the so-called green energy systems, Kunstler nonetheless urges us to move toward clean energy sources, regional economies, and lifestyles that are congruous with the planet’s diminishing energy resources.
While more politically moderate studies suggest that the global economy might slow down but rebound with new technological advances, the fact remains that we have already crested Hubbert’s Peak in the past five years (Deffeyes, 2005, p. 3). Furthermore, it is essential to remember that the remaining oil and natural gas under Canadian tar sands or oil shale in the western U.S. “could provide as much oil as the world’s current reserves, but the current methods of extraction are hugely greenhouse-intensive and environmentally problematic—not to mention expensive” (Henson, 2006, p. 289). Simply put, the world’s cheap, easily harvested oil is gone—and with it, the days of the global industrial food system are numbered as well.
Solution: At Catlin Gabel school, we not only teach Peak Oil and alternative energy in our studies of economics, science, history, and literature, we enact it with our symbolic “Empty the Lot Day,” which is a day that faculty, staff, students, and parents seek to reduce our school’s carbon footprint and do our part to keep the air clean for everyone. We encourage people to bike, walk, carpool, and take public transportation to work, charting the progress year to year, and incentivizing the process throughout the year by providing lunch tokens to teachers who carpool, bike, walk, or take public transportation to campus.
The Hunger reason
Problem: One in six Americans will struggle with hunger today (Levy, Mueller, Cochran, Hand, & Two Bulls, 2012, para. 1). This is a disquieting statistic, made even starker by the reminder that adults who struggle to feed themselves cannot often feed their children. In fact, “according to the USDA [U.S. Department of Agriculture], over 16 million children lived in food insecure (low food security and very low food security) households in 2010” (Feeding America, 2012). One’s heart fills with grief wondering, Is there simply not enough food to go around?
Frances Moore and Anna Lappé (2002) counter this question, though: “For every human being on the planet, the world produces two pounds of grain per day—roughly 3,000 calories, and that’s without even counting all the beans, potatoes, nuts, fruits, and vegetables we eat, too. This is clearly enough for all of us to thrive; yet nearly one in six of us still goes hungry” (p. 15). What then, is the cause of all this hunger?
Joel Bourne, Jr. (2009) notes that global population is booming, but so is global warming and deforestation of land for more production zones. We know how this pattern goes, if we follow Diamond (2005) and Ponting (1991). Acting as mitigates on grain production across the globe, are three other factors: one, global warming is sharply curbing harvests of rice, corn, wheat, sorghum, cassava, and sugar cane across the world; two, staple crops such as corn and soybeans are being fed to livestock as the desire for meat and milk products skyrockets among the millions of new middle class citizens; and three, more and more trees are being cleared to make way for fields that are being converted to biofuels in a well-intentioned response to global warming, which is, in a grimly ironic catch-22, causing erosion, topsoil loss, and desertification, thereby creating more hunger (Bourne, 2009). This is exemplar of the vicious circle involving the triad of hunger-overpopulation-global warming, I tell my students, and it will be the greatest challenge of their lives when they get older.
Solution: Our 5th grade teachers are tackling these issues head-on, teaching the children about local food systems as an antidote to the global food supply chain that is bad for the climate, the land, and the people. In 5th grade, they have the students research CSAs, farmers markets, farm to school programs, the 100 Mile Diet, and the Low Carbon Diet. They use Chew on This (Schlosser & Wilson, 2007), The Omnivore’s Dilemma: Young Reader’s Edition (Pollan, 2009), and What the World Eats (D’Aluisio & Menzel, 2008)to teach local food systems, biodiverse farming practices, sustainable agriculture, and nutritious eating with a low carbon footprint.
In the middle school, including the sixth grade, we continue the work of our lower school colleagues by doing monthly service projects with Portland based community groups, such as The Blanchet House, Urban Gleaners, and the Oregon Food Bank, who are all working to end hunger in Oregon.
I also advocate, in my classroom and in the garden, a turn away from grain for livestock, and land for monocrops or biofuels, and instead a return to the practice of smaller, biodiverse farms that feed families and communities. Biodiverse, organic fields have healthier soils than those used for conventionally farmed monocrops, and organic, biodynamic farmers cause far less erosion and topsoil loss, use far less water, and do not causes long-term soil toxicity as farmers using conventional chemical farming practices do. Looked at in the short-term, organic, biodiverse farms may appear less productive than the larger, conventional chemical monocrop farms, as the former are smaller and seemingly less bountiful. However, looked at in the long-term, the organic biodiverse farms actually do more to address hunger and environmental stability in the world, as their practices preserve soil, do not contaminate drinking water, and do less to add to global warming. Connecting hunger and global warming, I also share with my students Vandana Shiva’s (2009) research, which “has shown that using compost instead of natural-gas-derived fertilizer increases organic matter in the soil, sequestering carbon and holding moisture—two key advantages for farmers facing climate change” (p. 56). When we talk with our students about hunger, we do not simply talk about access to food, although access certainly is a factor; we also talk about climate change, population, geography, vegetarian vs. omnivore diets, local vs. global food supply, short-term bumper crop vs. long-term sustainability, and chemical vs. organic farming. All of these issues are relevant, obviously.
 Berry is a national treasure. Some of his many books include Bringing It to the Table (with Michael Pollan), The Unsettling of America, and What Are People For?
 Other writers also point out that the U.S. has evoked some antagonism around the world from its political support of the despotic Saudi regime in exchange for continued, cheap access to the bulk of the world’s crude oil reserves. See Chapter 11 of Rachel Bronson’s Thicker Than Oil. Still others suggest that both U.S. military strategy during foreign wars and the decisions to maintain hundreds of overseas bases are both predicated upon securing that access to oil. See Chapter 3 of Kevin Phillips’s American Theocracy and Chapter 4 of Chalmers Johnson’s Nemesis. Whatever one’s conclusions, it’s clear that both fossil fuel use and fossil fuel access come at great environmental and political costs.
