From lions in Kenya to snow leopards in the Himalaya, the big cats of the world need help. Tigers, cheetahs, leopards, jaguars, and other top felines are quickly disappearing, all victims of habitat loss and conflict with humans. The National Geographic Society has launched the Big Cats Initiative, a long-term commitment to sound the call that big steps are needed to save big cats around the world. Big Cats 2014 features beautiful images of these supreme predators.
