Ol Pejeta Conservancy, Nanyuki, Kenya:

Najin 33 one of the last two Northern White rhinos left in the world resting under a hot afternoon sun with her friend and caretaker Zachary Mutai in Ol Pejeta Conservancy. The northern white rhino is all but extinct. The two last males died several years ago. The two females are still with us, but too feeble to bear babies. In an Italian lab, their eggs are now artificially fertilized by sperm from the late males, and kept at minus 196 celsius, in hopes that surrogate rhinos from another sub species can carry the northern white back from the brink.
