The National Geographic-Big Cat Initiative: From lions in Kenya to snow leopards in the Himalaya, the big cats of the world need help. Lions, tigers, cheetahs, leopards, jaguars, and other top felines are quickly disappearing, all victims of habitat loss and degradation as well as conflicts with humans. To address this critical situation, the National Geographic Society and Explorers-in-Residence Dereck and Beverly Joubert, have launched the Big Cats Initiative, a comprehensive program that supports on-the-ground conservation projects, education, economic incentive efforts, and a global public-awareness campaign. "We no longer have the luxury of time when it comes to big cats," says Dereck Joubert. They are in such a downward spiral that if we hesitate now, we will be responsible for extinctions across the globe."
