BBC: Last male northern white rhino dies

The northern white rhino is one step closer to extinction after the final male dies in Kenya. The Ol Pejeta Conservancy, where the 45-year-old lived, now says:

“The only hope for the preservation of this subspecies now lies in developing in vitro fertilisation (IVF) techniques using eggs from the two remaining females, stored northern white rhino semen from males and surrogate southern white rhino females.”
