There are so few individuals left that they have a hard time finding a member of the opposite sex to produce new whales. (Most probable cause.)

Basically it´s the Norwegins who hunt some smaller species because of tradition and to eat them and the Japanese because they think whales are way better than Viagra and because they also eat the meat.
