Illegal rhino horn trade

In this Dec. 1, 2012, photo, a one-horned rhinoceros stands inside the Kaziranga National Park, a wildlife reserve that provides refuge to more than 2,200 endangered Indian one-horned rhinoceros, in the northeastern Indian state of Assam. Even in this well protected reserve, where rangers follow shoot-to-kill orders, poachers are laying siege to "Fortress Kaziranga," attempting to sheer off the animals' horns to supply a surge in demand for purported medicine in China that's pricier than gold.
