"Somewhere in the Pacific Ocean, a South Korean fishing vessel called the MFV Oryong 717 is hunting for fishing gear it left in the water to catch tuna. It won't find it. Greenpeace has hauled it aboard their ship for disposal.
It's just one more skirmish in an accelerating battle over the fate of one of the last great lions of the open ocean – the bluefin tuna. Its succulent flesh is so popular in sushi that its very existence is threatened. A single bluefin – they typically grow to eight feet and 800 pounds – may sell for $100,000 in Japan."
