Sonya responded to the Writing Prompt:Write an expository essay to present to your class about why invasive species are a problem near the Great Lakes.Read Sonya's essay below. 1 In November of 2019 a scientific study came out.It told about mercury levels in the Great Lakes' big game fish. The study was not good news. It showed that zebra mussels are destroying the food chain.They eat plants that were part of the diet of large fish like the lake trout.As a result. the lake trout must now eat large quantities of small fish that are high in mercury.Zebra mussels are an example of an invasive species, a species that is not native to the Great Lakes. Invasive species can harm the environment. They can also disrupt human activities,such as safely eating local fish. The zebra mussels did not come here on their own.A ship first brought them in the 1980s by accident when it dumped wastewate in the Great Lakes Zebra mussels found a perfect home in the Great Lakes.As they ate tiny plants, took food away from native animals.This changed the ecosystem.
