Environmental Ecology- Air Pollution

Air quality issues causes... 3 million deaths per year
1970 Clean Air Act Mandated EPA establish and enforce 6 Ambient Air Quality standards and established 188 Hazardous Air Pollutants (HAPs)
Ambient Air Quality Standards 1. Carbon Monoxide (CO) 2. Nitrogen Oxide (NO2) 3. Sulfur Dioxide (SO2) 4. SPM (Suspended Particulate Matter) 5. Photochemical Ozone (O3+Chemicals-->bad ozone) 6. Lead (PB)
New cars... Produce 75% less air pollution due to catalytic converters
Greatest Air Pollution ...Occurs in the home 2-5x more air pollution
Global Warming Should be looked at in different regions, not on global scale. Is a scientific consensus, not scientific proof
Natural Greenhouse Gasses 1. O2 2. H2O 3. CH4 (Methane) 4. N20 (Nitrous Oxide) Natural sources that control temp by trapping heat
Human Sources 1. Ag 2. Deforestation 3. Fossil fuels
Harmful Effects of Atmospheric Warming 1. Snow & Ice Melt 2. Oceans Rising 3. Disruption of Ocean Currents 4. Extreme Weather 5. Biodiversity Changes 6. Crop Growth locations shifted 7. Health Effects/Diseases 8. Permafrost Melt 9. Reduced Food Productivity-drought
