  • 1. CANADA’s Environmental Issues
  • 2. Environmental Issues
    • Acid Rain
    • Pollution of Great Lakes
    • Extraction and use of Natural resources on Canadian Shield
    • Timber Industry
  • 3. CANADA: The Great Lakes
  • 4. Acid Rain - Problem
    • Coal burning factories, cars, and trucks release chemicals that pollute the air.
    • The growth of industries and cities has caused air quality to decline, raising concerns about the effects of fossil fuel use and acid rain.
  • 5. Acid Rain & the Great Lakes
    • When chemicals from the factories join with water in the clouds, they form acid rain.
    • High levels of Acid rain can damage or kill trees an pollute lakes enough to kill fish.
  • 6. Acid Rain
    • Southern Canada experiences the highest levels of Acid Rain.
    • 50%-75% of pollution that actually causes Acid rain comes from the US (winds bring the pollution north towards Canada).
  • 7.  
  • 8. Acid Rain- Solution
    • Canada’s government has done several things to reduce pollution
      • Build factories that don’t pollute the air
      • Laws passed that require cars to produce less pollution
      • Encourage people to walk or ride bikes/buses.
  • 9. Pollution of Great Lakes
    • 1970’s: Great lakes had high levels of water pollution.
    • Fishing was unsafe; animals and plants were being killed
    • Factories used the lakes as a place to dump waste.
  • 10. Solution to Great Lakes
    • In 1972, the U.S. and Canada created the first “Great Lakes Quality Agreement” pledging to clean up and protect the Great Lakes ecosystem.
    • Goal is to restore lakes environment and prevent further damage.
    • Work together to reduce amount of waste and chemicals dumped into lakes
  • 11. Canadian Shield
    • Large area of thin rocky soil around the Hudson Bay.
    • Very Important to Canada’s economy
    • 1.5 million people make their living in the mining industry .
  • 12. The Canadian Shield
  • 13. The Canadian Shield
    • The Canadian Shield contains much of Canada’s mineral wealth, including diamonds.
    • Mining is the biggest industry in this area.
    • About 85 percent of the nation’s iron ore comes from mines near the Quebec- Newfoundland border.
    • The Canadian Shield has large deposits of gold, silver, zinc, copper, and uranium.
  • 14.  
  • 15. Extraction and use of Resources on Canadian Shield
    • Blasting and digging with heavy machinery causes the land around mines to be damaged and environment ruined.
    • Mining processes releases harmful chemicals into the air which causes Acid Rain.
  • 16. Solution to Extraction of Resources
    • Canada’s government has made new rules:
      • Reduce amount of mining allowed in the shield
      • Reduce exports of raw materials, but focus on manufactured goods like cars.
  • 17.
    • With almost half its land covered in forests, Canada is a leading producer of timber products.
    • These products include lumber, paper, plywood, and wood pulp.
    • The major timber – producing provinces include British Columbia, Quebec, and Ontario.
    Canada’s Timber Resources
  • 18. Timber Industry
  • 19. Timber Solution
    • Government and Industry are working together to manage use of the forest:
      • Hundreds of
    • When too many of these raw materials are removed or extracted from the environment, it hurts the environment permanently.
    • Historical and current over-extraction of minerals and timber has threatened the future of available resources.
