2. ENVIRONMENTAL PROBLEMS/SOLUTIONS Energy

3.  You’ve just been to Wal-Mart. Rather than throw away your bag, you decide to reuse it.  Brainstorm a list of ways to reuse the bag.

4. Environmental Problems  Pollution  Resource Depletion  Human Population Growth  Habitat Destruction

5. Pollution  What do you think of when you think of pollution? Which type of pollution do you think is worse?

6. Types of Pollution  Solid Wastes – (trash/ think of a landfill)  Chemicals – CFC’s and PCB’s (chlorofluorocarbons and polychlorinated biphenyl)  Radioactive Wastes (Nuclear power plants)  Gases – (Carbon Dioxide)

7. Solid Wastes Hazardous Wastes Waste that can catch fire, wear through metal, explode or make people sick

8. Chemicals – CFC’s and PCB’s  CFC – destroys the ozone  used in aerosols, refrigerators, and plastics.  (today, the use of CFC’s are banned but are still found in the atmosphere).  PCB’s – are poisonous.  Used in paints and appliances.  Cause cancer.  Banned but are still found in even the most remote areas on Earth.

9. Human Population Growth (Overpopulation)  The human population exhibits exponential growth.  As more people move around, more natural resourced are needed.  Eventually, the resources may become depleted and pollution level may rise.

10. biodiversity  Deforestation, point-source (marine habitat), non- point sources (water pollution)

11. Your Community Due the next day.  Draw a picture of what your commmunity might look like in the year 2100 if pollution and habitat destruction continue at a rapid rate.  Draw a picture on the other side showing what it looks like if the environmental problems are prevented

12. Prevention of Environmental Problems  REDUCE  REUSE  RECYCLE
