Pollution in the Great Lakes
Bacteria-laden beaches, lakes choked with algae and fish contaminated by industrial waste: these have been symptoms of pollution in the Great Lakes since the late 1950s. With growing threats to drinking water, wildlife populations and human health, governments on both sides of the border took action to reverse the Lakes' decline in the 1970s. Today they supply water to one-third of all Canadians and one-seventh of all Americans. Under the watchful eyes of scientists and environmentalists, the Lakes are slowly becoming great again.
