The northern white rhino ( Ceratotherium simum cottoni) didn't disappear overnight. Once they're gone, then the source of eggs disappears." "Those remaining females could all die tomorrow. "It's kind of a race against time," said Richard Vigne, CEO of Ol Pejeta. And though Sudan is the only male northern white rhinoceros left alive, the real technical challenge will come in harvesting enough eggs from the four remaining females to achieve a viable baby rhino. A natural pregnancy is impossible at this point, according to experts, who have turned to assisted reproductive technology instead. Now, researchers at the Ol Pejeta Conservancy, Sudan's home, and elsewhere are rushing to save this subspecies, of which only five individuals remain. Such is the life of Sudan, the last male northern white rhinoceros on Earth.

On a reserve in Kenya, the end result of this decimation lives out his old age under armed guard, his horn docked to make him less valuable to poachers. For decades, humans have slaughtered Africa's rhinoceroses, driven by the Eastern medicine market's demand for their horns.
