  1. Chapter 14 Resource Issues

  2. What is a Resource? Animals live in harmony with the environment, humans do not. How come? • Two major misuses of resources: • Depleting scarce resources • Destroy resources through pollution

  3. Why are Resources Being Depleted? • WHY ARE RESOURCES BEING DEPLETED • Energy resources • MDCs vs. LDCs • Animate power vs. Inanimate power • Biomass fuel • Fossil Fuel • Fossil fuels are fininte • Fossil fuels are distributed unevenly

  4. Why are Resources Being Depleted? • Finiteness of Fossil Fuels • Renewable vs. Nonrenewable energy • Remaining Supply of Fossil Fuel • Proven reserves • Potential reserve • Expanding Production • Coal mining • Oil shale

  5. Why are Resources Being Depleted? • Uneven Distribution of Fossil Fuels • Location of Reserves • Where’s the coal? • Where’s the oil? • Consumption of Fossil Fuels • LDCs vs. MDCs

  6. Why are Resources Being Depleted? • Control of World Petroleum • OPEC • Politics and OPEC • Changing Supply and Demand • Making Cars • Dwindling reserves

  7. Why are Resources Being Depleted? • Nonrenewable Substitutes for Petroleum • Natural Gas • Coal

  8. Why are Resources Being Depleted? • Nonrenewable Substitutes for Petroleum • Nuclear Energy • Potential accidents from Nuclear • Fission • Radio active waste from Nuclear • Bomb Material from Nuclear • Limited Uranium Reserves • High Cost of Nuclear Power

  9. Why are Resources Being Depleted? • MINERAL RESOURCES • 92 natural elements on Earth • Only 8 are on the Earth’s crust • Metallic or Nonmetallic Minerals

  10. Why are Resources Being Depleted? • Nonmetallic minerals • Phosphorus • Potassium • Calcium • Sulfur

  11. Why are Resources Being Depleted? • Metallic Minerals • Ferrous Metals • Iron • Manganese • Chromium • Titanium • Magnesium • Molybdenum

  12. Why are Resources Being Depleted? • Alloying elements • Nickel • Tin • Tungsten

  13. Why are Resources Being Depleted? • Nonferrous Metals • Aluminum • Copper • Lead • Zinc • Precious metals • Silver • Gold • Platinum

  14. Why are Resources Being Polluted? • AIR POLLUTION • Pollution • Global-scale Air Pollution • Global Warming • Greenhouse Effect • Global-Scale Ozone Damage • Ozone • Chlorofluorocarbons • Freon

  15. Why are Resources Being Polluted? • Regional-scale Air Pollution • Acid deposition • Acid precipitation (AKA acid rain) • Doesn’t fall where it is produced • Life expectancy

  16. Why are Resources Being Polluted? • Local-scale Air Pollution • Carbon Monoxide • Hydrocarbons • Photochemical smog • Particulates

  17. Why are Resources Being Polluted? • WATER POLLUTION • Water Pollution Sources • Let it be someone else’s problem • Water-using industries • Municipal sewage • Agriculture

  18. Why are Resources Being Polluted? • Impact on Aquatic Life • Biochemical Oxygen Demand • Water Temp • Wastewater and Disease • Less wastewater in LDCs and MDCs

  19. Why are Resources Being Polluted? • LAND POLLUTION • Solid Waste Disposal • Sanitary Landfill • Incineration • Burning trash • Centralia, Pennsylvania • Hazardous Waste • Love Canal, New York

  20. Why are Resources Reusable? • RENEWING RESOURCES • Leading Renewable Energy Sources • Biomass • Hydroelectric Power • Wind Power • Geothermal Energy • Nuclear Fusion

  21. Why are Resources Reusable? • Solar Energy • Passive Solar Energy • The sun’s energy is free and limitless • Capture the sun’s energy without special devices • Glass technologies • Active Solar Energy • Photovoltaic cells • Heat to electricity

  22. Why are Resources Reusable? • Uses for Renewable Energy • Electricity • LDCs have more need of Photovoltaic cells • Motor Vehicles • More MDCs are using electric vehicles • How come people are slow to change to electric cars?

  23. Why are Resources Reusable? • RECYCLING RESOURCES • Recycling has increased each decade since the 1970s • Recycling Collection • Pick-up and Processing • Curbside, drop-off, buy-back, deposit • Manufacturing • Paper, plastic, glass, aluminum

  24. Why are Resources Reusable? • Other Pollution by Reduction Strategies • Reducing discharges • Take out the pollutants • Increasing Environmental Capacity • Where and when the discharge of pollutants occurs matters • A Coking Plant: Using all Reduction Strategies • Comparing Pollution Reduction Strategies

  25. Why can Resources be Conserved? • SUSTAINABLE DEVELOPMENT • Conservation • Preservation • Sustainability and Economic Growth • 1987 Brundtland Report • China: 16 of 20 most polluted cities • Sustainability's Critics • WWF (World Wildlife Fund) • Reduce the gap between MDCs and LDCs

  26. Why can Resources be Conserved? • BIODIVERSITY • Biological and Geographic Biodiversity • Genetic diversity • Human’s have not discovered all the Earth’s species • Land convervation • Biodiversity in the Tropics • Destruction of the Rain Forest • For money in a LDC

  27. The End
