they need to keep it clean because it is a lot of fresh water. and you can't live without water. if the Great Lakes are dirty then there goes a lot o the worlds fresh water. And because we drink this water.
Restore fish and wildlife habitats and prevent sewage contamination.
They have to keep it clean because most of Illinois's drinking water is made from the great lakes
Because
No one, but I guess you could say that the states where they are located have some rights over them. Michigan had to clean up Superior due to pollution.
Lake Erie is one of the five Great Lakes located on the border between the United States and Canada
then
Because they share it with Canada in fact they flow into the st.Lawrence thus becoming Canada's problem if America mucks it up and that would cause political strife as well as it being a good source of fresh water which should be preserved. That and the organisms in the lakes would die causing an ecological imbalence.
The Great Lakes are a valuable resource for the people living around them. All fresh water resources need to be kept unpolluted and clean. People fish, boat, swim, camp, and live around the water in the lakes and pollution kills animals, people, and bird/ water life.
they put waste into the lakes until the clean-up in the early 90's
Some lakes have polution issues (especially those crowded with resorts), but mostly the lakes are pretty clean.
Sometimes
-Population growth is going up by millions.-The forest land in the region is expanding.-The lakes are soooo clean that people want to live near them.-People are told that they can live near the lakes as long as they keep them clean.-The lakes are still a beautiful enough to watch.-Builders must replace the amount of wetland that they destroy.-The government knows the value in wetlands.
No. The Canadian Shield is not a province but a landform somewhat in the shape of a shield. If you look at a map of Canada, you may notice the great lakes. If you look to the west and then toward the north west toward the Arctic other lakes continue the pattern of the great lakes. If you look to the east of the great lakes you will notice the St. Lawrence River opens up something like a large lake. Those lakes provide the border of the Canadian Shield. It was an area numerous glaciers scraped clean. It also contains the oldest surface rock in North America. (Newer rock probably once graced its land. It became terminal moraines such as Long Island, New York.) The Shield is found in several provinces.
