The Alliance for the Great Lakes works to protect the Great Lakes for today and tomorrow.
We involve tens of thousands of people each year in advocacy, volunteering, education, and research to ensure the lakes are healthy and safe for all. Learn more about our campaigns and how you can get involved.
The Great Lakes hold 20% of the world’s supply of surface freshwater, and provide drinking water to 40 million people in the region. Your support will help protect these lakes and preserve their legacy of clean water for generations.
