Lions, 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 has launched the Big Cats Initiative, a comprehensive program that supports on-the-ground conservation projects, education, and economic incentive efforts and a global public-awareness campaign. "We no longer have the luxury of time when it comes to big cats," says National Geographic Explorer-in-Residence Dereck Joubert. "If there was ever a time to take action, it is now." You can help us make a difference. Your donation can help save a big cat and ensure the Earth is not without these majestic creatures. Please donate today! You also can help by signing up for Big Cats Initiative updates with the Geo-Link Newsletter.
