In a move that’s enraged and baffled conservationists, the Chinese government announced Monday that it was legalizing the use of rhinoceros horns and tiger bones for traditional medicine and medical research. Trade of the two substances has been banned in China for 25 years. China’s cabinet clarified that only certified hospitals and doctors would be allowed to use the animal parts ― and said the substances would have to come from rhinos and tigers raised on farms, excluding zoo animals. Environmentalists, however, have denounced the decision as a huge blow to rhino and tiger conservation efforts and a major win for traffickers of illegal animal parts. Leigh Henry of the World Wildlife Fund said it will be “incredibly difficult” to tell rhino and tiger parts obtained legally from farms apart from those acquired from wild animals. “It’s a devastating decision,” Henry, the WWF’s director of wildlife policy, told The New York Times. “I can’t overstate the potential impact.”

With only around 3,900 left in the wild, every tiger counts. But China’s latest move to lift the ban on tiger bone trade threatens to put a dark cloud over the world’s wild 🐯 — WWF 🐼 (@WWF) October 29, 2018

In traditional Chinese medicine, rhino horns and tiger bones are considered potent healing ingredients that can treat a host of ailments including cancer. There is no scientific research, however, to support these claims. And in recent years, leaders in the field have discouraged the use of both substances, the Times noted. China has not explained why it decided to reverse its 1993 ban on the animal parts. Peter Knights, chief executive of environmental nonprofit WildAid, said the decision came “completely out of the blue and with no rationale.” Environmental groups told National Geographic that the growing number of tiger farms in the country ― and apparent efforts to farm rhinos too ― may have been a factor in China’s decision. Others have suggested that the move may be linked to efforts by the government to boost the growth of the multibillion-dollar traditional Chinese medicine industry.

With only around 3,900 tigers and 30,000 remaining rhinos in the world, conservationists say China's reversal could have a devastating impact on the endangered wild animals. https://t.co/Xf7knrNqfn — Twitter Moments (@TwitterMoments) October 30, 2018
