For East Africa's lions, is the future bright?

Wildlife conservationists, faced with declining numbers of lions in East Africa, have come up with ways of keeping the remaining cats out of danger.

A National Geographic advertisement captures it succinctly: “The cat’s hunting abilities are outstanding; he actively stalks his prey,” says the commentator. But the video shows a domestic cat chasing a little red laser light in a plush home with pristine white sofas. The message: If we do not do something fast to conserve the big felines, domestic cats might have to be used as a stand-in, and these are the kind of videos that the National Geographic will be forced to make to illustrate the life of lions, tigers, cheetahs and leopards.

East Africa is famous for its wildlife, and lions are at the top of the hierarchy. But researchers fear that lions may be extinct in a few decades.
