2. CANADA’s Environmental Issues

3. Environmental Issues Acid Rain Pollution of Great Lakes Extraction and use of Natural resources on Canadian Shield Timber Industry

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. 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.

8. 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.

9. The Canadian Shield

10. 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.

12. 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.

13. 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.

14. 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

15. 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.
