A sub-species of the black rhino that roamed the earth for 8 million years has been declared extinct, according to a 2011 review by the International Union for Conservation of Nature's (IUCN). The animal hasn't been seen in the African wilderness since 2006 due, almost exclusively, to widespread poaching and a lack of conservation efforts. Sadly, the fate of this sub-species is not unique: Rhinoceros populations across Africa and Asia are said to be disappearing at an alarming rate. The animals are hunted for their horns, which are considered an aphrodisiac. This belief has spurred a lucrative black market that is pushing rhinoceros to the brink of extinction.
