16. 1963, Clean Air Act: The EPA (environmental protection agency) set out standards for what was to be considered “ criteria pollutants”. Several of these original pollutants were Carbon Monoxide, Sulfur Dioxide, lead, etc. As of 1970's there were two types of quality air standards set out by the EPA: primary standards: meant to protect human health secondary standards: aimed to protect welfare like crops, livestock, visibility, etc.

17. EPA discouraged Smoke Stacks as the stacks were spreading the smoke and causing acid rain. -acid rain is caused from sulfur dioxide reacting with water molecules and elevating hydrogen ion levels. -negative effects of plants and animals -diminishes the nutrient content in soil which results in less vegetation; affecting live stock -you may suffer asthma and lung problems over time. -Chicago's level of sulfer oxide is .015 parts per million, -highest rated city, Pittsburgh, which has near .025 ppm of sulfer oxide .

19. Chinese Ministry of Health says lung cancer is a leading cause of death due to air pollution from factories -Much of the pollution over Los Angeles originates in China, according to the Journal of Geophysical Research.

20. -U.S. vehicle emissions contribute 45% to global warming -Vehicle exhaust contributes to: -60% of carbon monoxide emissions(US) -95% in large cities -Every year 335,000 Americans die of lung cancer, which is a direct result of air pollution. Ways to cut down emissions: -Don ’t buy products that come in aerosol spray cans -Carpool with friends and coworkers -Don ’t smoke
