The river is rebounding but the cost has been crushing. Nixon has buried twenty-one of his young volunteers, victims of the epidemic street violence. When the deaths of these youth was not covered in newspaper, Nixon and the Corps created a youth journalism program to document their positive contributions. The resulting Earth Conservation Corps films have spawned a movement of disenfranchised urban youth to combat poverty, youth violence and environmental injustice. Nixon's cutting edge contributions in film and conservation have widely recognized including an Academy Award Nomination, five Emmy Awards, the President's Service Medal by President Bill Clinton, "Hero of the Planet" by the National Geographic Society, "Educator of the Year" by Chesapeake Bay Foundation, by the Walter Cronkite Award and as a Hometown Hero by WETA. Mr. Nixon's work has been profiled on "Now with Bill Moyers", "60 Minutes", People Magazine, The Washington Post, TheNew York Times, ABC World News Tonight, PBS, NPR's All Things Considered, CBS Morning News, National Geographic Channel and media outlets around the world.
