The article describes an alarmingly crass profit-motivated assault on the dwindling blue-fin tuna stocks. It is a conceivable plot, given the Japanese cultural penchant for delicacies that threaten both shark and whale populations. Unfortunately, the evidence that Mitsubishi intends to decimate the species is asserted by a former fisherman turned filmmaker, but no corroboration is presented. The company contends it is following normal procedures, but both WWF and Greenpeace are agitated about the internationally sanctioned overfishing, which is also exacerbated by illegal catches.

An amazing scheme is alleged: fishing bluefin to extinction in order to freeze supplies of extinct food to sell at huge profits. Mitsubishi denies the intent. The article includes other information about causes of overfishing that is threatening species extinction.
