Robert F. Kennedy, Jr. leads the nation's fastest growing grass-roots environmental organization, The Water Keepers Alliance. Like an environmental "neighborhood watch" program, Water Keepers take polluters to court, respond to citizen complaints, identify problems that affect bodies of water, devise appropriate remedies, and serve as living witness to the condition of the ecosystem. The Waterkeepers chronicles the heroic efforts of river, bay, and sound keepers from Alaska to North Carolina.
