BBC: Apes 'extinct in a generation'

Some of the great apes - chimps, gorillas, and orangutans - could be extinct in the wild within a human generation, a new assessment concludes.

Human settlement, logging, mining and disease mean that orangutans in parts of Indonesia may lose half of their habitat within five years.

There are now more than 20,000 humans on the planet for every chimpanzee.

Read the whole thing and then go feel very sad.
