3. 3 How nature works. How the environment effects us. How we effect the environment. How we can live more sustainably without degrading our life-support system.

4. 4 Human Population The human race plays a key role in important issues we will be discussing the whole year  Population growth  Poverty  Loss of biological diversity  Pollution  Global climate change  Resource use

5. 5 Fig. 1-1, p. 6 Industrial Revolution ? Agricultural revolution Hunting and Gathering Billions of people Time Black Death—the Plague The Population Dilemma – exponential growth

6. 6 50% of people still trying to survive off < $3/day deplete and degrade environment Wealth is becoming increasingly concentrated

7. 7 Premature extinction of species Why is losing biodiversity so critical?

8. 8 Pollution- Natural occurrences Biogenic Human activities Anthropogenic

9. 9 Occurs more in urban areas Can contaminate area where produced or be carried away by wind or water Factors that determine the damage a pollutant can cause: Concentration Persistence Chemical nature Rate of degradation

10. 10 Population growth, resource use, poverty, and loss of biological diversity contribute to climate change Global warming

11. 11 Natural capital- Earth’s resources and ecological services Air Water Soil Forests Fishery Minerals Natural water and air purification

17. 17 Never leave it worse than you found it Take only what you need Sustain diverse living organisms Maintains Earth’s capacity for self- repair Decrease waste Decrease pollution Decrease population

18. 18 A measure of human demand on earth’s ecosystems Looks at consumption of: Energy Food Building material Water Other resources
