According to a report by the United Nations Environment Programme, at least 22,218 great apes have been lost to wildlife traffickers between 2005 and 2012.
The nearly 3,000 great apes lost each year have been either killed, sold, or died in captivity.
64 percent of the apes that have been lost have been chimpanzees.
According to the report, live chimpanzees are available for sale by wildlife traffickers for as little as $50. There has also been a report of a zoo in Malaysia purchasing a gorilla for $400,000.
