Canada Environmental Issues

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