Lately The Great Lakes have been getting very polluted! Michigan and all the states surrounding it are causing very large amounts of pollution. Chicago Illinois has a huge city full of cars, a subway station, and even an airport, all of which have large amounts of pollution from gas and the exhaust that comes out of the vehicles.
Another way that is affecting the lakes, is the habitat that the animals are living in are getting destroyed and is causing all the animals too leave, which completely destroys the concept of the lake. The lakes are so big that the fish in the lake are also breathing in all the nasty pollution and getting sick and even dying!
