In Mozambiques Gorongosa National Park, elephants are in crisis: Years of civil war and ivory poaching have left them frightened and hostile toward humans. In a new National Geographic Television film, the worlds foremost elephant researcher Dr. Joyce Poole, in a documentary by her brother, cameraman Bob Poole, works to build trust and retrain the animals away from their violent behavior. The screening will be followed by a discussion with the Pooles, NGTV Sr. Producer David Hamlin, and Mateus Mutemba, Gorongosa National Park Administrator.
