How do human affect the Earths resources?

• Problems created by Air Pollution

• GLOBAL WARMING
• Increase in yearly, global temperature
• Caused by greenhouse effect
• CO2 from burning fossil fuels, blankets Earth
  trapping in suns heat

How do human affect the Earths resources?

• Problems created by Air Pollution

• OZONE DEPLETION
• Use of polluting CFCs breaks ozone down allowing
  suns harmful rays to pass through
• Increases incidence of skin cancer

Assessment

• Work with your partner to create a flow chart of
  a can of soda from its creation to its disposal
  to demonstrate how it pollutes the environment

40
Aluminum Can Pollution

• 1. Aluminum dug out of ground (land pollution,
  scars land, uses minerals up)

41
Aluminum Can Pollution

• 2. Impurities washed from aluminum (water
  pollution)

42
Aluminum Can Pollution

• 3. Aluminum transported to can plant (need
  fossil fuels for car, burning creates air
  pollution)

43
Aluminum Can Pollution

• 4. Plant makes can (energy needed)

44
Aluminum Can Pollution

• 5. Cans transported to market (uses up fossil
  fuels, creates air pollution)

45
Aluminum Can Pollution

• 6. Person buys soda, drinks it, puts in garbage
  (land pollution- landfill)

46
Assessment

• Write the following assignment into your agenda
• Natural Resource Review Questions
• When finished, use the rest of the period to work
  on your pamphlet project

Every American Born Will Need..

• Look at the Every American Born Will Need
  Handout
