In this photo taken on Jan. 24, 2014, bears look out from a cage at a bear farm in Dangjin, south of Seoul, South Korea. Several bears lie stacked on top of each other, as still as teddy bears, as they gaze out past rusty iron bars. Others pace restlessly. The ground below their metal cages is littered with feces, Krispy Kreme doughnuts, dog food and fruit. They’ve been kept in these dirty pens since birth, bred for a single purpose: to be killed for their bile. (AP Photo/Lee Jin-man)
