Nothing was said in your article about the situation in Canada, where killing bears for their gallbladders and paws is a serious problem. I suggest that you contact TRAFFIC North America and the World Wildlife Fund–Canada for detailed information on the problem in Canada.

The article states, “Traditional medicine has been driving an active trade in bear bile and gallbladders, which produce it.” Bile is produced by the liver and stored in the gallbladder.
