A man in panda clothes picks panda tea leaves in Ya'an, Sichuan province, on March 17, 2012. An Yanshi says he wants to grow tea using panda excrement as fertilizer – because of pandas' diet of bamboo -- and then sell the leaves for 219,865 yuan ($34,500) per 500g. All the profits will be devoted to charity. But he admits he has no idea how he can get his hands on enough panda waste or what effect it will have on the tea. [Photo/Asianewsphoto]
