  1. Part 1: Environment The Science Behind the Stories www.aw-bc.com/Withgott

  2. Chapter 1: Introduction to Environmental Science • Environmental Science is the study of how the natural world works, how our acts affect its condition and viceversa. • Use of renewable and nonrenewable sources • Human population growth • Malthus: Human population growth needs to be controlled or the resources won't be enough; Easter island case • Social and environmental impact • ecological footprint: lobster overfishing

  3. The Nature Of Environmental Science www.aw-bc.com/Withgottt

  4. Perception depends on: • age • gender • social class • home location • educational background

  5. Nature of Science • Scientific Method • observation • question(s) • hypothesis • testing • experiment • results • statistical analysis • conclusions

  6. Testing Hypothesis • manipulative and natural experiments • manipulative experiments • paleontology: too old/few to experiment • cosmology: too large/far away to experiment • natural experiments • experiments can be conducted naturally without manipulation • Ecology is a mixture of both types of experiments

  7. Scientific process • scientific method • peer review • conference presentations • grants & funding for the study • repetitions • Theory is produced • paradigm: the theory can shift with time

  8. Sustainability • population + consumption = environmental impact • What do you think of the footprints of different societies? • Do countries with bigger footprints have an obligation to reduce it? • Do third world countries, have the obligation to retain the low footprint they already have before developing economically and industrially?

  9. Sustainable Development • environmental protection • economic welfare • social equality • The End www.aw-bc.com/Withgottt
