National Geographic: Lion Warriors 2010

On the Great Plains below Mount Kilimanjaro in Kenya, lions are attacking Maasai cattle, as they have for hundreds of years. And the proud Maasai warriors have hunted them ruthlessly in return so that now only about 2,000 remain in the country. If their numbers drop any lower, their populations will not be sustainable. Now the Maasai elders and chiefs are recognizing that the threat to their lions is also a threat to their way of life, and have forbidden the warriors from hunting them. Wildlife filmmaker Kire Godal, with the support of executive producers Dereck and Beverly Joubert, captures firsthand the struggle of these modern-day warriors who are reinventing their traditions to help save the lions they once prided themselves on killing.
