The company is in the bear bile business. They have bear farms in which bile is taken out and used in traditional Chinese medicine and for other purposes. Bile is a liquid that is produced in the liver and stored in the gall bladder( 胆囊). In bears (and in humans too), bile is necessary to help digest fatty foods. Traditional Chinese medicine uses bear bile to treat pain, fever and vision problems. Bile for traditional Chinese medicine used to be collected by killing bears, but it was discovered that bear bile could be got by keeping the bears alive and just “milking” them by putting a rubber tube into the bodies of bears. Unfortunately, this is a painful process and the bears have to live a life of suffering. Animal rights groups want this practice to stop. They say it is a cruel way to treat animals. Guizhentang disagrees. They say the practice isn’t harmful and that they are actually helping the bears. There are fewer Chinese black bears, from which the bile is taken, because human activity is taking over the forest the bears live in. The company says bear farms are a way to protect the species. On the one hand, we use many types of animals for food, clothing, medicine and for medical research. On the other hand, we should know that causing animals great pain is wrong. There are man-made substitutes( 替代品) for bear bile that work just as well as the real thing, so bear farms aren’t really necessary. If Guizhentang really wants to protect the black bear, they should perhaps think about getting out of the bear bile business. ( ) 1. Guizhentang has been criticized because ________. A. it kills a lot
