  10. ESC110 Chapter One Understanding our Environment Principles of Environmental Science - Inquiry and Applications, 2nd Edition by William and Mary Ann Cunningham

  11. Chapter One Some Key TermsMcGraw-Hill Course Glossary • logical thinking • paradigms  positivism •  reflective thinking •  remediation •  restoration ecology •  scientific theory •  sustainability •  sustainable development •  analytical thinking •  creative thinking •  critical thinking •  deductive reasoning •  environment •  environmental science • global environmentalism • hypothesis •  inductive reasoning

  12. Chapter 1 • Understanding Our Environment; • Science as a Way of Knowing; • Thinking About Thinking; • A Brief History of Conservation and Environmentalism; and • Human Dimensions of Environmental Science.

  13. Understanding Our Environment The Planet Earth • Unique in the universe (?); • Mild, relatively constant temperatures; • Biogeochemical cycles; • Millions of species; and • Diverse, self-sustaining communities.

  14. What is Environmental Science?? • The Natural World – plants, animals, soils, air, water • Humans – social institutions and their artifacts (eg, political orgs, science, technology, etc) • Integrating these two can affect the environment • Negatively?? so the more we learn about the environment the better we can develop solutions • Environmental Science

  15. Environmental Science • Environment is the circumstances and conditions that surround an organism or a group of organisms as well as the complex of social & cultural conditions that affect an individual or community; • Environmental science is the systematic study of our environment and our place in it.

  16. What's Happening to the Frogs? In some places, up to sixty-percent of frogs and salamanders have abnormal limbs, digits, eyes, or internal organs. Environmental science allows us to explore the possible causes of such problems. (observational &/or experimental)

  17. Science as a Way of Knowing • Modern science has its roots in antiquity; • Greek philosophers; • Arabic mathematicians and astronomers; and • Chinese naturalists.

  18. Scientific Investigation • Deductive vs. inductive reasoning; • Hypothesis - a conditional explanation that can be verified or falsified; and • Scientific theory - an explanation that is supported by an overwhelming body of data and experience

  19. Models and Natural Experiments Models • Simulate real environmental systems; • Can be physical or mathematical; • Provideheuristic information (suggestions of how things MIGHT be); and • Are influenced by researchers' assumptions. Natural Experiments • Gathering of historic evidence; and • Conducted by scientists who can't test their hypotheses directly.

  20. Probability and Statistics Quantitative data • Precise and easily compared; and • Good benchmarks for measuring change. Probability • Measure of how likely something is; and • High degree of scientific certainty: 95% probability. Statistics • Important tool in both planning and evaluating scientific studies; and • Sample size, number of replications important.

  21. Applied Science Many environmental scientists want to use their knowledge to repair ecological systems that have been damaged by humans.

  22. Restoration Ecology Restoration - the re-creation of species composition and ecosystem functions in areas disrupted by human actions The Kissimmee River - the focus of an ambitious $8 billion restoration project.

  23. Restoration Tools • Labor-intensive horticultural or animal control methods • Removal of exotic species

  24. Restoration Issues • Natural disturbance (fires, hurricanes, etc.) • Multiple historic states • Climate changes and evolution • How do we distinguish between desirable and undesirable change?

  25. Artificial Ecosystems • Example: human-designed wetlands can be used to treat sewage effluent

  26. Thinking About Thinking
