The Cove is a 2009 documentary film directed by Louie Psihoyos which analyzes and questions dolphin hunting practices in Japan. It was awarded the Academy Award for Best Documentary Feature in 2010. The film is a call to action to halt mass dolphin kills, change Japanese fishing practices, and to inform and educate the public about the risks, and increasing hazard, of mercury poisoning from dolphin meat. The film is told from an ocean conservationist's point of view. The film highlights the fact that the number of dolphins killed in the Taiji dolphin drive hunting is several times greater than the number of whales killed in the Antarctic, and asserts that 23,000 dolphins and porpoises are killed in Japan every year by the country's whaling industry. The migrating dolphins are herded into a cove where they are netted and killed by means of spears and knives over the side of small fishing boats. The film argues that dolphin hunting as practiced in Japan is unnecessary and cruel. Wikipedia
Richard O'Barry: The thing that turned me around was the death of Flipper, of Cathy. She was really depressed. I could feel it. I could see it. And she committed suicide in my arms. That's a very strong word, suicide. But you have to understand dolphins and other whales are not automatic air breathers, like we are. Every breath they take is a conscious effort. And so they can end their life whenever life becomes too unbearable by not taking the next breath. And it's in that context I use the word suicide. She did that. She swam into my arms, looked me right in the eye, and took a breath... and didn't take another one.
