Riverkeeper

Dive headfirst into the history of environmental activism in the Hudson River watershed and learn how you can help organizations like Riverkeeper protect clean water around the globe!

Every inch of the United States is in a river's watershed. But in 1966, one of our most important watersheds was dying. Dead fish washed up on the Hudson River's shores, and the once-clear water reeked of oil. With too much pollution to support human or animal life, America's "First River" was in too deep—until a Riverkeeper, a pioneering group of environmental activists, fought to get rivers around the globe out of troubled waters.

Nonfiction pro Nancy Castaldo showcases Riverkeeper's achievements and the intersection of science and activism. With forty striking photographs and profiles of prominent water protectors, this resource-packed text is both a deep-dive into the history of the environmental movement and a guidebook for how individuals and communities can shape its future.
