Transcript of Environmental Issues in Canada

Environmental Issues in Canada
Canada is the second largest country in the world.
Canada is known for its natural resources.
Canada is made up of lakes, numerous rivers, majestic mountains, and rolling central plains.
The Canadian Shield is rocky mass that covers nearly half of Canada. The Canadian Shield also includes hilly region of lakes and swamps that stretch across northern Canada.
The Canadian Shield has some of the oldest rocks on Earth.
Canada's forests are home to a variety of wildlife. Canada's lakes and rivers hold about 20 percent of all fresh water on Earth. These lakes and rivers are home to trout and salmon.
Canada is a wealth of natural resources that are renewable and non-renewable resources.
Canada faces many environmental issues!

Canada has many natural resources. Canada must find ways to carefully manage resources so that the environment is not harmed.

Some of the environmental issues in Canada:
Acid Rain
Timber being removed or clear-cutting
Pollution of the Great Lakes
Extraction and use of Natural Resources in the Canadian Shield area

The environment is being negatively altered by human activities. Cars, Power stations, and factories contribute to pollutants being released in the air. Pollutants such as Sulfur dioxide, carbon dioxide, and nitrogen oxides are put into the air. These pollutants mix with water molecules and turn the water acidic. Clouds or rain droplets that are acidic are called acid rain.

Acid rain causes many problems in the environment:
kills plants and wildlife
damages or kills trees
pollutes lakes and rivers enough to kill fish

Canada's timber is important to the economy. Canada is a leading producer of timber products.
Loggers cut the trees and then send them to mills.
Mills use the timber to make a variety of products including lumber, plywood, and wood pulp for making paper.

The Forests serves many important roles:
plants and animals depend on the forest to live
provides oxygen to the atmosphere
filter out pollutants in air

Concerns that logging will destroy the forest include:
deforestation and erosion
Logging, deforestation, and clear-cutting endanger wildlife and plant life


People and Industries in Canada rely on water from the Great Lakes. Canada has half of the word's freshwater supply. The Great Lakes are shared between the United States and Canada.
It is important for the two counties to work together to keep the lakes clean and share responsibilities of caring for lakes

By the 1970s, the Great Lakes were being used as dumping sights for factories and water pollution became a concern. Clean up efforts had to be addressed due to drinking water contatining dangeous chemicals, fish found in some rivers were not to be eaten due to toxins, and wildlife endangered due to pollutents found in the rivers.

In 1972, The Great Lakes Water Quality Agreement between the United States and Canada was established to limit factories from dumping chemicals into the air, soil, and water surrounding the Great Lakes. The great Lakes Water Quality Agreement established between Canada and United States addresses cleaning, protecting, and restoring the Great Lakes.

Positive Changes are being made in Canada to protect the environment and address future challenges
Studing Air quality
Reducing contamination
Keeping water clean
Conserving Canadian wildlife
Reducing As emissions
Pollution of Great Lakes
Mining is a large industry in Canada.
Resources such as copper, gold, zinc, iron ore, nickel, diamonds, and uranium are found in the Canadian Shield.
Extraction of non-renewable resources can not be replaced. Non-renewable resources include minerals or natural gases.
Damage to the Candian Shiled has occured with heavy machinery due to mining. The digging and blasting with heavy machinery causes damage to the surrounding areas of the mines.
Chemicals from the mining are released in to the air which cause acid rain. Mining disrupts the ecosystem.

Citizens and Industries need to work together and provide education to protect the Great Lakes and Canadian Shield
Laws are needed to protect natural resources, timber, and water sources in order to prevent further damage.
Too many resources are extracted and overused and cause permanent environmental consequences.
Promote educational programs in the classrooms to address waste, air pollution, and other environmental issues.
Factories and Mining industries need to be held to a higher standard by using products that are safe for the environment.
