7. LBJ continued Clean Air Act Amendments (1965) Established exhaust emission standards for cars Air Quality Act (1967) Set guidelines on air pollution & increased federal gov’ts power to enforce clean air standards

8. Nixon’s Policies R. Nixon Silent Spring (1962) Rachel Carson published; warned of the harmful effects of chemicals on the natural world Led to Earth Day demonstrations Clean Air Act (1970) Regulated levels of air pollution EPA established (1970)

9. Environmental Protection Agency The White House and Congress established the EPA in response to the growing public demand for cleaner water, air and land. Task of the EPA: Repair the damage already done to the natural environment Establish new criteria to guide Americans in making a cleaner environment a reality.

10. EPA continued… EPA leads the nation's environmental science, research, education and assessment efforts The mission of the EPA is to protect human health and the environment.

11. Carter’s Policies J. Carter Alaska National Interest Lands Conservation Act Protected more than 100 million acres of land & doubled the size of the nation’s park & wildlife refuge system

12. Carter continued… 3-Mile Island Love Canal, NY Environmental disaster Long-buried chemicals began seeping up through the ground Exposure was linked to high rates of birth defects

13. To Do: In your opinion, which president did the most for the environment? Justify/defend your answer. Consider: Theodore Roosevelt, Lyndon B. Johnson, Richard Nixon, or Jimmy Carter

14. IPCC The U.N. formed a group of scientists called the International Panel on Climate Change, or IPCC. The IPCC meets every few years to review the latest scientific findings & write a report summarizing all that is known about global warming. Each report represents a consensus, or agreement, among hundreds of leading scientists. To Do: Why is it important that an international group of scientists meet to discuss environmental issues? Explain.

15. Environmental Issues Climate change Global warming Global dimming Fossil fuels Sea level rise Greenhouse gas Ocean acidification Conservation Species extinction Pollinator decline Coral bleaching Poaching Endangered species Energy Energy conservation Renewable energy Efficient energy use Environmental Degradation Habitat destruction To Do: Of the 4 environmental issues listed, which one do you think we should be most concerned with & why?

16. Issues continued… Genetic engineering Genetic pollution Genetically modified food controversies Intensive farming Overgrazing Irrigation Environmental effects of meat production Overpopulation Burial Land degradation Desertification Soil, Soil conservation, Soil Erosion, Soil Contamination, Soil salinization Land use Urban sprawl Habitat fragmentation Habitat destruction Nuclear Issues Nuclear power Radioactive waste To Do: Of these 6 issues, which one do you think is most concerning & why?

17. Issues continued… Ozone Depletion Pollution Water pollution Acid Rain Marine pollution Ocean dumping Oil spills Ocean acidification Wastewater Air pollution Smog Indoor air quality Resource Depletion Exploitation of natural resources (over- consumerism) Fishing; Bottom trawling; Illegal & unregulated fishing; Shark finning; Whaling Logging / Clearcutting / Deforestation Mining Toxins Chlorofluorocarbons DDT Dioxin Heavy metals Herbicides Pesticides Toxic waste

18. GROUP PROJECT In assigned groups, you will research one of the following topics. Acid Rain Air Pollution Global Warming Animal/Species Extinction Deforestation Ozone Depletion Ocean Issues (pick 1 issue or all 3) sea water rising, oil spills, wastewater, & pollution
