This is not a wide known problem, which makes it so much more of a problem. The Japanese claim its 'research'. But they are actually making protucts from the blubber of the whales, and somehow disposing of the rest of the whale. They catch and kill the whale by going in huge tarpoon boats. When they see a large whale, they send a huge spear into the side of the whale, and drag it up a huge ramp, into the boat. Watching this is a horrible sight. Please, to find out more information, watch 'Whale Wars' on animal planet, or go to AnimalPlanet.com and type in Whale Wars.
