Have You Ever?

Have you ever wanted to go to a Great Lake? Have you wondered why people tell you that you shouldn’t go to a Great Lake? Well the reason to that is because of the pollution, and invasive species there. That leads to habitat loss for the animals in the Great Lakes.

Pollution in the Great Lakes

The pollution in the Great Lakes is really bad. People would throw their trash, factories would send smoke in the air or oil in the Great Lakes. Animals died and some became endangered. The point-source pollution that harms the Great Lakes are from discharge pipe at a sewage treatment plant or a factory. But new laws helped with getting rid of pollution in the Great Lakes. The laws put strict limits on the amount of phosphorus and other chemicals that industries and sewage treatment plants could release into the water of the Great Lakes. Other laws banned the use of a number of toxic chemicals, like PCB and DDT.

The Invasive Species in the Great Lakes

Invasive species are fish or animals from other oceans or rivers that had a passage way to get into the Great Lakes. They could kill a whole school of fish or make the habitat around them ruined. There are more than 185 invasive species in the Great Lakes today! Sea lamprey and alewife have all damaged the Great Lakes ecosystem. Zebra mussel steal food from native species. They also clog water pipes. They attach to docks and make swimming dangerous to humans because of their sharp shells. The Asian Carp is also another big problem to the Great Lakes. Catfish Farmers in America buy these fish to clean out their ponds. Some have escaped and are migrating towards Lake Michigan. A way how they are getting rid of the invaders our getting other species that would eat the invaders. Pacific Salmon has been introduced to Great Lakes to control the alewife there. Alewife numbers have dropped because of this and the native fish have begun to recover.

Habitat Loss in the Great Lakes

Fish and other animals lose their habitat or food so some died and some became endangered. When the loggers were here they didn’t worry about habitat loss, no one was worried about habitat loss until today. Habitat loss wouldn’t help our economy since we get food, resources, and many other things from animals. So people that are in groups to save the animals that we really need. The farm animals are ok since farmers take care of their animals but other animals like fish, the bald eagle, and other birds that eat fish usually died off or got endangered because of all the pollution. So people that were in the groups helped keep the animals that were endangered safe.

To Conclude

And with that we conclude that you need to help protect the Great Lakes. You have to protect them from pollution, and the invasive species. And make sure that what you do doesn’t make the animals in the lakes have habitat loss because of something you did. And that’s why it’s important for people like you and me, to protect the Great Lakes for they will once again be great.
