Apes 'extinct in a generation'

"Some of the great apes -- chimps, gorillas, and orangutans -- could be extinct within a human generation, an authoritative 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."
