About 70% of the world’s ivory is sold in China, making it the largest ivory market in the world. The valuable commodity reaches a price of up to a thousand dollars on Chinese markets, most of which will be closed down in the next three months. Environmental groups, like the World Wildlife Fund, have welcomed China’s historic decision and said that it would help preserve endangered elephants around the globe. According to recent reports, the elephant population in Africa has gone down by a third in the past decade. Last year alone over 20,000 elephants were killed. The WWF estimates that about half a million elephants still roam Asia and Africa. The international ivory trade has been forbidden since the end of the 1980s, but some countries have continued to allow selling and trading ivory. 4.
