7. Ozone Ozone is good in the stratosphere but bad in the troposphere. Human activities affect both types. http://airnow.gov/index.cfm?action=goodup.page1 http://air-purifier-review.toptenreviews.com/air-purifier-vs.-ozone-generator.html

8. Textbook Resources McDougall, p.A32 Human activities produce chemicals that destroy the ozone layer. CFCs Some natural processes put chlorine into the stratosphere, but about 85 percent of the chlorine there comes from human activity. Chemicals called chlorofluorocarbons (KLAWR-oh-FLUR-oh- KAHR-buhnz) have been manufactured for use in cooling systems, spray cans, and foam for packaging. These chemicals break down in the stratosphere and release chlorine and other ozone-destroying chemicals.

9. Human Activities affect the atmosphere Create a 6-sided brochure about air pollution. Due by Tuesday at the beginning of class.
