In this photo taken Thursday, Feb. 27, 2014 and provided by Esmond Martin, market-sellers stand by souvenirs made of ivory for sale at the Benfica market on the outskirts of Luanda, Angola. The market on the outskirts of Angola's capital sells more than 10,000 pieces of ivory, making it the largest market in southern Africa to openly sell illegal elephant tusks, according to two researchers who traveled to Luanda and surveyed the items of ivory for sale, seeking to raise awareness of the dangers the ivory trade poses to the existence of Africa's elephants.
