Yet another reason why very large predatory animals are challenging to farm:

A Chinese man who raised bears to tap them for their bile, prized as a traditional medicine in Asia, has been killed and eaten by his animals, Xinhua news agency said on Tuesday.

Six black bears attacked keeper Han Shigen as he was cleaning their pen in the northeastern province of Jilin on Monday, Xinhua said.

When you read the details of what this guy was doing to these critters, the headline will start making a lot more sense. Sometimes I think if it weren't for "traditional Asian medicine" the whole concept of endangered species would've been obsolete long ago.
