Use and Abuse of Earth’s Resources

1. Use and Abuse of Earth’s Resources By: Brianna Shields March 9, 2005

2. DO NOW • 1. How is renewable resource defined? • 2. Name one problem with the use of fossil fuels • 3. What is one problem with using hydrogen as a source of energy?

3. GOAL • To distinguish between renewable and nonrenewable resources

4. Overuse of resources Fossil Fuels Minerals Water Land Animal Products How do human affect the Earth’s resources?

5. Pollution The release of substances into the environment, that change it for the worse How do human affect the Earth’s resources?

6. Land Pollution A. Fossil Fuel Removal Scars land, strips soil, mining chemicals seep into ground How do human affect the Earth’s resources?

8. Land Pollution B. Improper storage of factory wastes How do human affect the Earth’s resources?

9. Land Pollution C. Radioactive waste storage How do human affect the Earth’s resources?

10. Land Pollution D. Solid waste- garbage from homes and industries Dumped in landfills Methane gas released Chemicals seep into ground How do human affect the Earth’s resources?

11. Air Pollution A. Burning of fossil fuels due to industry and cars How do human affect the Earth’s resources?

12. Types of Air Pollution B. Smog- thick haze created when air pollutants react with sunlight Eye, respiratory problems How do human affect the Earth’s resources?

13. Types of Air Pollution C. Acid Rain- air pollution combines with water droplets Kills aquatic life Damages forests Wears away buildings How do human affect the Earth’s resources?

15. Types of Air Pollution D. Indoor air pollution Wood, coal, gas stoves Air fresheners Disinfectants, cleaners Smoking How do human affect the Earth’s resources?

18. 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 sun’s heat How do human affect the Earth’s resources?

19. Greenhouse Effect Diagrams

20. Greenhouse Effect Diagram

21. Problems created by Air Pollution OZONE DEPLETION Use of polluting CFC’s breaks ozone down allowing sun’s harmful rays to pass through Increases incidence of skin cancer How do human affect the Earth’s resources?

22. Ozone Layer Diagram

23. Ozone Depletion Diagram

24. Ozone Depletion Diagram

25. Water Pollution 1. Acid Rain Kills aquatic life Pollutes drinking water Ruins beaches How do human affect the Earth’s resources?

27. Water Pollution 2. Mining chemicals leak into water supply How do human affect the Earth’s resources?

28. Water Pollution 3. Oil drilling and transportation accidents Exxon Valdez Oil Spill How do human affect the Earth’s resources?

31. Water Pollution 4. Hot water from nuclear power plants dumped back into water How do human affect the Earth’s resources?

32. Water Pollution 5. Buried hazardous waste leaks How do human affect the Earth’s resources?

33. Water Pollution 6. Sewage draining into rivers/streams How do human affect the Earth’s resources?

34. Water Pollution 7. Fertilizer and animal waste runoff from farmland How do human affect the Earth’s resources?

35. Water Pollution Two types A. Point source= water pollution discharged through sewers, pipes How do human affect the Earth’s resources?

36. Water Pollution Two types B. Non-Point source= water pollution resulting from landfills, runoff, etc. How do human affect the Earth’s resources?

39. 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

47. Every American Born Will Need…….. • Look at the “Every American Born Will Need” Handout • How many resources does each U.S. citizen use during his lifetime?
