In an announcement that could prove to be extremely good news for elephants in the wild, the Chinese government has promised to end its domestic ivory market by the end of this year.Every year, thousands of elephants are killed for their tusks by poachers. Between 2011 and 2014, more than 100,000 elephants were slaughtered. The African elephant population dropped 30 percent from 2007 to 2014. More elephants are being killed than are being born.
