[ Lake Erie Death Watch ] By Barry Yeoman for the NRDC

Brought back from the brink once before, a Great Lake again faces biological collapse

What would it mean to lose one of our Great Lakes? The environmental and economic calamity could devastate the region’s tourism, sport fishing industry, drinking water supply, and wildlife, and could also take a toll on human health. And there would be plenty of blame to go around, from changing agricultural methods to inattentive politicians to weaknesses in our nation’s bedrock environmental protections — many of which can partially trace their existence to concern over Lake Erie in the first place.

Erie is the most fertile of the Great Lakes: It contains only 2 percent of their water but 50 percent of their fish. Its biological abundance, and its location in a densely settled corner of the Midwest, make the prospect of collapse all the more frightening. If conditions grow worse, imploding native fish populations could decimate Lake Erie’s recreational fishing industry. (Fishing generates $7 billion a year throughout the Great Lakes.) The water supply for 11 million people could become undrinkable without expensive treatment. And blue-green algae, linked to liver cancer in China and fatal poisonings in Brazil, could pose a grave threat to people here, too, particularly if ingested.
