象牙替代品——针对河马牙国际贸易的快速评估（译）

Following several developments — including an auction of hippo teeth and a proposed cull of hippos in Tanzania, the cancellation and reinstatement of a hippo cull in Zambia, and a call for evidence on hippo ivory trade by the United Kingdom — there has been increased interest in this often-overlooked ivory trade. There are additional concerns that the prohibition of domestic commercial trade in elephant ivory in numerous countries/ territories globally may lead to an increase in trade of hippo ivory as a substitute. Given these concerns, some government authorities and non-governmental organisations have called for more information regarding the international trade in hippo ivory.
