Video: saving dolphins from slaughter: Weather Channel's Brink series "Those dolphins," says O'Barry of performing dolphins, "don't represent real dolphins in the ecosystem. "The whole time," he adds, "they are suffering because everything about captivity for a dolphin is unnatural." O'Barry's Dolphin Project is devoted to the opposite: "Untraining them and putting them back in the wild where they belong." His work has often led him into hard situations: He's been threatened by fishermen and arrested numerous times, and he believes a colleague was killed for her activism. But his work has also led to real victories: a growing public awareness of the conditions in which captive dolphins are held, as well as the banning of dolphin capture in the United States. Additionally, according to the Dolphin Project, O'Barry "has rescued and released more than 25 captive dolphins in Haiti, Colombia, Guatemala, Nicaragua, Brazil, the Bahamas Islands, and the United States." Still, there is much more to be done. "My goal is to be put out of business," O'Barry says. Someone like me should not be needed. This video is a Weather Channel production.
