1 Understanding Our Environment Frameworks for Understanding: Science, Systems, and Ethics Matter, Energy, and Life Environmental Science 2

2 Important Definitions Environment: the living and non- living surroundings throughout Earth. Environment: the living and non- living surroundings throughout Earth. Environmental Science: the study of our environment and our place in it. Environmental Science: the study of our environment and our place in it.

3 Some Origins of Interest 1. Resource conservation 2. Moral/aesthetic preservation 3. Concerns about human health and ecological damage 4. Global environmental citizenship

4 U.S.A. History of Environmentalism through Conservation, and Preservation Conservation: Conservation: Teddy Roosevelt – Progressive Movement, Presidency, and National Forest EstablisherTeddy Roosevelt – Progressive Movement, Presidency, and National Forest Establisher Gifford Pinchot – Forester, Presidential Advisor, National Forest Establishment LeaderGifford Pinchot – Forester, Presidential Advisor, National Forest Establishment Leader Preservation: Preservation: John Muir – Naturalist, Activist, Resource Management Specialist, Sierra Club President, California National Park EstablisherJohn Muir – Naturalist, Activist, Resource Management Specialist, Sierra Club President, California National Park Establisher Aldo Leopold – Botanist, Author, Wilderness Society FounderAldo Leopold – Botanist, Author, Wilderness Society Founder

5 Concerns via Modern Science, Organizations, and Media Concerns via Modern Science, Organizations, and Media Rachel Carson – Biologist, Author, ActivistRachel Carson – Biologist, Author, Activist David Brower – Director of Sierra Club, Friends of the Earth, Earth Island InstituteDavid Brower – Director of Sierra Club, Friends of the Earth, Earth Island Institute Barry Commoner – Scientist, Researcher, ActivistBarry Commoner – Scientist, Researcher, Activist Global Eco/Socio-Cultural Citizenship Global Eco/Socio-Cultural Citizenship Dr. Wangari Maathai – Green Belt Movement, Grassroots Feminist, Governance in Ministry (Kenya), Nobel Peace Prize RecipientDr. Wangari Maathai – Green Belt Movement, Grassroots Feminist, Governance in Ministry (Kenya), Nobel Peace Prize Recipient U.S.A.

7 Globalization The exchange of people, information, and things… all over the planet. The exchange of people, information, and things… all over the planet. The Good: human migration and interaction, advancements in education and healthcare, better standards of living, diversity and freedom…The Good: human migration and interaction, advancements in education and healthcare, better standards of living, diversity and freedom… The Bad: rural resource extraction, international trade of goods away from suffering native populations, industrial operations resulting in pollution, global warming…The Bad: rural resource extraction, international trade of goods away from suffering native populations, industrial operations resulting in pollution, global warming… The Ugly:The Ugly:

8 Sustainability: the path to The Good Living within the bounds of nature based on renewable resources used in ways that dont deplete nonrenewable resources, harm essential ecological services, or limit the ability of future generations to meet their own needs. Living within the bounds of nature based on renewable resources used in ways that dont deplete nonrenewable resources, harm essential ecological services, or limit the ability of future generations to meet their own needs.

9 Science: knowledge production through logical processes Related terms: Related terms: accuracy, reproducibility, reasoning, hypothesis, and theoryaccuracy, reproducibility, reasoning, hypothesis, and theory Scientific method Scientific method 1.Question/purpose 2.Hypothesis/educated guess 3.Data collection/experimentation 4.Results analysis/answer 5.Report theory/review 6.Publish findings/implement

10 Consensus and Conflict Agreement vs. Dissent Agreement vs. Dissent Paradigm: a model that provides a framework for interpreting observations. Paradigm: a model that provides a framework for interpreting observations. Paradigm shift: the adoption of an innovative understanding of some phenomena and/or processes, based on updated scientific research and new conclusions embraced by the scientific majority.

11 Environmental Ethics Value Value Intrinsic vs. Extrinsic

12 Environmental Justice (Progressive Worldviews) Civil Rights + Environmental Protection = A Safe, Healthy, Life-giving Environment for Everyone Civil Rights + Environmental Protection = A Safe, Healthy, Life-giving Environment for Everyone Diversity, Tolerance, Equity Diversity, Tolerance, Equity People/Places Benefiting: People/Places Benefiting: Americans (U.S.A), Australians (Australia), South Africans (South Africa)…Americans (U.S.A), Australians (Australia), South Africans (South Africa)… People/Places In Need: People/Places In Need: Sudanese (Sudan), Korean (North Korea), Iranian (Iran)…Sudanese (Sudan), Korean (North Korea), Iranian (Iran)…

13 Connections When one tugs at a single thing in nature, he finds it attached to the rest of the world. - John Muir Interrelationships: Interrelationships: MatterMatter EnergyEnergy LifeLife

14 Definitions Matter: everything that takes up space and has mass (weight). Matter: everything that takes up space and has mass (weight). Energy: the ability to do work (movements, transfers, and so on). Energy: the ability to do work (movements, transfers, and so on).
