What We Do

Imagine a New York and Connecticut where the vitality of nature is protected for people and wildlife. A region in which citizens from all walks of life unite to transform struggling habitats, polluted waters, endangered wildlife, and a threatened planet into vibrant, inspiring places that sustain communities. With your passion and our experience, together we’ll keep your air healthy, your water clean, and the natural places you love safe—now and for future generations.

Saving the Sound and Its Rivers

From the Sound’s open waters to the halls of Congress, we’re there—finding and stopping water pollution, restoring fish and wildlife habitat to vibrant health, and strengthening shoreline communities. We’ve been fighting for the Sound and its rivers for over 40 years, and we won’t stop until it’s healed.
