Some of the world’s most exotic animals could be extinct within months, conservationists have warned, with future generations growing up in a world without many of the species that are alive today.

The WWF claims that some animals, such as the vaquita porpoise, could be wiped out in the next few months.

Some would now be extinct had zoos not provided a ‘Noahs Ark’ from which to reestablish populations.

Habitat loss, poaching, hunting and disease are pushing many species to the brink to such an extent that the world has now entered a sixth mass extinction.
