  2. Key Concepts • Growth and Sustainability • Resources and Resource Use • Pollution • Causes of Environmental Problems

  3. Living More Sustainably • Ecology (Biologists) • Environmental Science (Natural and social scientists study the earth, our interactions with it, and how to deal with problems. • Sustainable Society • Living off interest vs. capital • Carrying capacity

  4. Population Growth Fig. 1-2 p. 4 • ExponentialGrowth • Doubling Time/Rule of 70

  5. World Population Fig. 1-1 p. 2

  6. Economic Growth • Gross National Product (GNP) (Our Total) • Gross Domestic Product (GDP) (Our Inside Part) • Gross World Product (GWP) (World Total) • Per Capita GNP (Average)

  7. Economic Development • Developed Countries (US, Canada, Japan, Australia, NZ, Europe) • Developing Countries • Positive Aspects (Life expectancy doubled, food production outpaces population growth, SDW increase, more goods/less materials, pollution decline in developed countries) • Negative Aspects (Life expectancy and pollution control lag in developing countries, unsustainable natural resource use, population competing with wildlife habitats, self-inflict climate changes)

  8. Globalization Economic (Trade) Information and Communication (Internet) Environmental Effects (Transport of species/disease)

  9. Resources • Perpetual • Renewable • Non-renewable Fig. 1-6 p. 9

  10. Renewable Resources • Sustainable Yield • Environmental Degradation (exceeding sustainable yield) • Tragedy of the Commons

  11. Non-Renewable Resources Economic Depletion Fig. 1-7 p. 10 • Energy Resources • Metallic Resources • Non-MetallicResources • Reuse • Recycle

  12. Ecological Footprint Fig. 1-8 p. 10

  13. Pollution • What is pollution? (Anthropogenic vs. natural) • Effects of Pollution Sources • Point • Nonpoint

  14. Dealing With Pollution • Prevention (Input Control) • Cleanup (Output Control)

  15. Environmental and Resource Problems Fig. 1-10 p. 12 • Major Problems(See Fig. 1-9 p. 12) • Five Root Causes

  16. Environmental Impact Fig. 1-11 p. 13

  17. Environmental Interactions Fig. 1-12 p. 14

  18. Environmental Worldviews • Planetary Management • We’re in charge, • There’s always more, • All economic growth is good, • Success depends on understanding, controlling, and managing the earth for our benefit. • Environmental Wisdom • Nature’s in charge, • Some things are limited, • Technology and economic growth can be bad, • Success depends on learning how the earth adapts and integrating how nature acts in to how we act.
