1
CANADAs Environmental Issues
2
Environmental Issues
  • Acid Rain
  • Pollution of Great Lakes
  • Extraction and use of Natural resources on
    Canadian Shield
  • Timber Industry

3
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.

4
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.

5
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).

6
Pollution of Great Lakes
  • 1970s 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.

7
Canadian Shield
  • Large area of thin rocky soil around the Hudson
    Bay.
  • Very Important to Canadas economy
  • 1.5 million people make their living in the
    mining industry.

8
The Canadian Shield
9
The Canadian Shield
  • The Canadian Shield contains much of Canadas
    mineral wealth, including diamonds.
  • Mining is the biggest industry in this area.
  • About 85 percent of the nations iron ore comes
    from mines near the Quebec- Newfoundland border.
  • The Canadian Shield has large deposits of gold,
    silver, zinc, copper, and uranium.

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.

12
Solution to Extraction of Resources
  • Canadas 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.

13
Canadas Timber Resources
  • 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.

14
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.
