The last northern white male rhino has had to be put down in Kenya as he was suffering.

RIP Sudan
The only chance for this northern white rhino now relies on in vitro fertilisation of the 2 remaining females
Poachers should have their 'horns' cut off
Sudan's death at the age of 45 leaves only two females of his subspecies alive in the world.
