Nelson Brooke is the Black Warrior Riverkeeper, one of 350 Waterkeeper organizations that are defending local waterways world wide. RFK Jr discusses Nelson's job and battles protecting our blue planet in this special Earth Day episode.

Coal pollution -- from mining, to burning, to the storage of leaky coal ash waste -- present the biggest threats to water, air, and public health in Nelson Brooke's Black Warrior River basin, which provides the drinking water for over one million Southerners. Brooke was hired for his "dream job" in 2004 by his childhood friend David Whiteside, who founded Black Warrior Riverkeeper in 2001.
