In the news: Mapping the threats to the Great Lakes

There are a number of different threats to the environmental health of the Great Lakes. 34 threats, to be precise.

That number is according to a study and accompanying map made by researchers at the University of Michigan. The map helps to identify the environmental stresses to each of the Great Lakes, and provides a snapshot of all five lakes as a system.

From WZZM 13 Online:
"Among the biggest threats: Invasive mussels and lamprey that threaten the food chain, climate change that can affect water temperature and water levels, ballast water from ships that may introduce more uninvited species, a buildup of urban areas along the coast that sweeps auto and human waste into the waters during rainfall, and a continual runoff of phosphorous from farmlands.

In contrast, mining and a dwindling ice cover in the winter remain a threat to Lake Superior, said David Allan, the project's lead researcher and a professor of aquatic sciences at the University of Michigan's School of Natural Resources and Environment."
