The Great Lakes hold one fifth of the world's fresh surface water supply and currently provide drinking water to over 42 million people. The health of these lakes is critical.
Pledge to Protect the Great Lakes
There are so many reasons to love the lakes: they provide a fifth of the world's fresh surface water and a home to countless unique species. They also add adventure, serenity, and beauty to our lives.
Help us protect the Great Lakes by taking a pledge to use less water, plant a tree, connect a rain barrel, or start using non-toxic cleaners.
Join people from across the region in taking a pledge to protect the Great Lakes!
Protect the Great Lakes from stormwater pollution by growing native plants and landscaping with rain gardens. Native plants are recommended because they are adapted to the wet springs and dry summers of region.
The root systems of most native plants are deep and help to loosen the soil which improves the ability of water to filter into the ground. This makes native plants perfect for rain gardens and for absorbing rainwater, which helps prevents stormwater pollution into our rivers and lakes.
Get started this Spring by taking Sierra Club's Green Garden Pledge!
