Six tons of carvings, jewelry, trinkets and tusks were being reduced to powder Thursday afternoon (Nov. 14) as the United States, for the first time, destroyed its ivory stockpile. The U.S. Fish and Wildlife Service (FW had collected the items over the past 25 years through smuggling busts and border confiscations. Though the international ivory trade was banned in 1989, there are still domestic markets and lucrative black markets around the world where ivory is in high demand. "Some argue that the seized ivory should be sold to alleviate the demand for ivory," Dan Ashe, director of the FWS, wrote in a blog post today.
