To celebrate Earth Day, the creators of the documentary 'The Cove' appeared on 'The Oprah Winfrey Show' (weekdays, syndicated). 'The Cove' is a film that exposes the yearly slaughter of thousands of dolphins in a village in Japan. Though some of the dolphins are sent to zoos, the vast majority are killed and eaten for meat. So many dolphins are killed in the hunt that the blue water is turned to red.

To celebrate Earth Day, the creators of the documentary 'The Cove' appeared on 'The Oprah Winfrey Show' (weekdays, syndicated). 'The Cove' is a film that exposes the yearly slaughter of thousands of dolphins in a village in Japan. Though some of the dolphins are sent to zoos, the vast majority are killed and eaten for meat. So many dolphins are killed in the hunt that the blue water is turned to red.

Filmmakers Richard O'Barry and Fisher Stevens created the documentary. Security was so tight in the Japanese village that some of the cameras had to be disguised as rocks, so that none of the villagers would notice the filming. The filmmakers want the killing to stop, and want the film to be seen by more of the Japanese public. O'Barry says that he hopes to "make people change."

The dolphin slaughter shown in 'The Cove' reveals one of the last organized dolphin hunts in the world.
