Animals are endangered in all areas of the world. To measure their risk, IUCN (International Union for Conservation of Nature) which consists of thousands of conservation groups from around the world, publishes a Red List of threatened species every year.
The Red List is broken down into 7 categories:
Extinct (gone forever)
Extinct in the Wild (species survives only in zoos)
Critically Endangered (clinging on in the wild in tiny numbers)
Endangered (has larger populations, but are still at risks)
Vulnerable (will soon be endangered if not protected)
