The giant panda has to be the best-known endangered species on the planet, thanks to the efforts of the World Wildlife Fund (among a host of others). In Save the Panda, National Geographic followed WWF-funded scientists as they made the first outside expedition into the People's Republic of China to study and, ultimately, help preserve these environmental icons. You'll see historical footage of panda hunting, the "panda-monium" that seized the Western world midcentury as a few dozen found their way into zoos, and the efforts of China and international organizations to help these animals deal with loss of habitat and a deadly bamboo die-off.
