Great Lakes Issues

Pollution, invasive species and wasteful water use all threaten our Great Lakes. The Alliance and our individual supporters are on the front line, predicting and responding to these threats in order to sustain a thriving ecosystem for the lakes and all their inhabitants.

Who We Are

For more than 40 years, the Alliance has stood to conserve and restore the world’s largest surface freshwater resource using policy, education and citizen involvement. We work hard with our strong volunteer network of residents, teachers, scientists and businesses to sustain and preserve the region for all generations.
