Did you know that all across Michigan we have numerous environmental issues, most lye in the Great Lakes
The Great Lakes are a freshwater ecosystem that is home to many plants and animals in the food chain as well as many people.
Exactly right! For example, if a fish ate a toxic chemical such as DDT then a Bald Eagle ate that fish, not only would the fish have that chemical in their system, so would the Bald Eagle, this would cause the bald eagle's eggs to have a soft and easily puncturable shell.
With the large amounts of people in the Great Lakes ecosystem also comes pollution that can be harmful to the foodchain.
There are two types of pollution, point-source pollution, and non-point-source pollution, point- source pollution is pollution from one spot, an example would be a discharge pipe at a sewage plant leading straight into a lake, non-point-source pollution, on the other hand, is pollution from many different places, an example of this would be air pollution from factories.
Another problem caused by people moving into the Great Lakes ecosystem is building on top of and destroying the natural habitats of plants and animals.
This is called habitat loss, an example of habitat loss is when people cut down trees that are the homes to many animals, like birds and squirrels.
In addition to human ruining the Great Lakes ecosystem, other animals are too, these animals are non-native animals known as invasive species. Invasive species have been found to steal native species food, be a disruption to the ecosystem and the people in it, and harm native species.
This is an example of a "Sea Lamprey" sucking the blood out of the " Native Trout."
