Great Lakes
From Wikipedia, a free encyclopedia written in simple English for easy reading.
The Great Lakes are five very big lakes in eastern North America. They are, in fact, the biggest fresh water lakes in the world (freshwater is water that is not salty like the ocean). Four of the Great Lakes are shared between Canada and the United States of America. Lake Michigan is the only great lake that is all inside the United States.
The lakes are:
Water flows from Lake Superior and Lake Michigan into Lake Huron; then through the Detroit River into Lake Erie; then through Niagara Falls into Lake Ontario; and then through the Saint Lawrence River to the Atlantic Ocean.

Why the Great Lakes need to be Cleaned Up
In my opinion the Great Lakes still need to be cleaned more because there is still pollution, it is inevitable that people would keep flying airplanes, which pollute, or stop boats from harboring in the lakes, which also pollutes them. The Great Lakes have to be cleaned up so that we, humans, will have sufficient amounts of drinking water, and not have to end up filtering the salt water that comes from the ocean. Now if we take a look at all the invasive species that have entered the food chains and webs of the Great Lakes we will see that the sea lampreys cause the deaths of most the lake trout, and the zebra mussels take in the PBCs from the water, and when other fish eat them the PBCs enter the food chain, going all the way to us, humans. The salmon population has been replacing the trout, which people think is successful, but the native species that feasted on the trout would have a harder time copping with the salmon, as they are much bigger and faster than the native trout. Also the algae that grows there is in such large quantities that it is lethal if a large amount of water is consumed by an animal that lives in the Great Lakes. If we take notice that the wetlands are quickly being manufactured into farmland, or the shores are being used for recreational purposes, we would see how much damage we have done to whole ecosystem of the Great Lakes. I think that we have to clean up the lakes, but after that we have to leave them alone, they are very important to us, as they provide over 90% of the fresh water on the whole earth. This is why the Great Lakes must be further cleaned and tended to this is not an option as all of North America and Canada rely on the plentiful fresh water of the Great Lakes. So if you’re a person who thinks the Great Lakes are clean think again after you’ve read this, if you still don’t want to continue cleaning, or if you change your mind for the health of the world and the largest fresh water source in it, the Great Lakes.
