Robert F. Kennedy, Jr.'s reputation as a resolute defender of the environment stems from a litany of successful legal actions. Mr. Kennedy was named one of Time magazine's “Heroes for the Planet” for his success helping Riverkeeper lead the fight to restore the Hudson River. The group's achievement helped spawn more than 190 Waterkeeper organizations across the globe.

Mr. Kennedy serves as Senior Attorney for the Natural Resources Defense Council, Chief Prosecuting Attorney for the Hudson Riverkeeper and President of Waterkeeper Alliance.  He is also a Clinical Professor and Supervising Attorney at Pace University School of Law’s Environmental Litigation Clinic and is co-host of Ring of Fire on Air America Radio.  Earlier in his career he served as Assistant District Attorney in New York City.

He has worked on environmental issues across the Americas and has assisted several indigenous tribes in Latin America and Canada in successfully negotiating treaties protecting traditional homelands. He is credited with leading the fight to protect New York City's water supply. The New York City watershed agreement, which he negotiated on behalf of environmentalists and New York City watershed consumers, is regarded as an international model in stakeholder consensus negotiations and sustainable development.

Among Kennedy's published books are the New York Times’ bestseller Crimes Against Nature (2004), The Riverkeepers (1997) and Judge Frank M. Johnson, Jr: A Biography (1977) and two children’s books St Francis of Assisi (2005), American Heroes:  Joshua Chamberlain and the American Civil War and Robert Smalls:  The Boat Thief (2008).
