Guess how many elephants are killed each day in Africa.
NAIROBI, Kenya — The British government is holding an international conference in London Wednesday and Thursday on the illegal wildlife trade, aimed at protecting endangered species and ending an illicit business that threatens security and the environment.
Among the worst affected species are Africa's elephants and rhinos, as their ivory and horns are trafficked to the markets of China and the Far East.
