Born Free Foundation - Keep Wildlife in the Wild

Bears are inquisitive and opportunistic and can suffer particularly badly in captivity.  Bears in zoos and circuses can display many abnormal behaviours, such as bar-biting, swaying from side to side, or even self-mutilation, while dancing bears are forced to perform.  Born Free campaigns to end the confinement and exploitation of bears and all wild animals for ‘entertainment’.
