• Youve 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.

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

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
