Everyone can make a distinct contribution toward ensuring a healthy future for our Great Lakes. Through responsible decision making, community involvement and partnerships, the Alliance advances its ecological mission. See how you can do your part!
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.
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.
