5. Tackling the Problems Why are Environmental problems so complicated? difficult to see direct cause and effect relationships between individual human activities and specific environmental damage. difficult to see direct cause and effect relationships between individual human activities and specific environmental damage. The problems seem enormous. The problems seem enormous. Preventing pollution is expensive, and cleaning up problems after the fact is even more expensive.

6. Tackling the Problems (Success Stories) 1. Clean up of Lake Erie (since the 1970’s). 2. Peregrine falcons nesting near the Bay of Fundy despite their dramatic decline due to the rampant use of the pesticide DDT. 3. Electrical utilities now promote energy conservation. 4. Emission controls and catalytic converters.

7. Our Main Environmental Problems Main threats to the global environment: Overpopulation Overpopulation Resource depletion Resource depletion Pollution (air, water and soil), global warming, ozone depletion and acid rain Pollution (air, water and soil), global warming, ozone depletion and acid rain Reduction in biodiversity and extinction Reduction in biodiversity and extinction

8. Our Main Environmental Problems— Overpopulation Any increase in population directly affects the environment. Any increase in population directly affects the environment. The pollution of natural environments, declining energy reserves, reduced biodiversity and wildlife extinctions are all problems related to human population growth The pollution of natural environments, declining energy reserves, reduced biodiversity and wildlife extinctions are all problems related to human population growth
