  1. Environmental Problems/Solutions By: Mr. Hunter

  2. 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.

  3. Environmental Problems • Pollution • Resource Depletion • Human Population Growth • Habitat Destruction

  4. Pollution • What do you think of when you think of pollution? Which type of pollution do you think is worse?

  5. Types of Pollution • Solid Wastes • Chemicals • Radioactive Wastes • Gases

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

  7. Chemicals • Compare/contrast CFCs PCBs

  8. Nonrenewable/Renewable Resources • Renewable Resource: a natural resource that can be replaced at the same rate at which the resource is consumed • Nonrenewable Resource: a resource that forms at a rate that is much slower than the rate at which it is consumed

  9. Renewable or Nonrenewable? • Sunlight • Wind • Natural Gas • Coal • Iron • Fresh water • Trees

  10. Renewable • Sunlight • Wind • Fresh water • trees

  11. Nonrenewable • Natural gas • Coal • Iron

  12. Renewable vs. Nonrenewable • Are there any items on the renewable list that could become nonrenewable?

  13. Renewable • Many renewable resources could become so polluted or overused that they would no longer be valuable.

  14. Human Population Growth • 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.

  15. biodiversity • Deforestation, point-source, non-point sources

  16. Your Community • 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

  17. Prevention of Environmental Problems • REDUCE • REUSE • RECYCLE
