Extinction is a normal part of the changing natural world but it is happening faster than ever before.
According to scientists' estimates, the rate of extinction throughout the world is somewhere between one and five species per year. Scientists around the world keep a watch on different plant and animal populations.

Extinct - there are no more left in the species, none have been found for more than 50 years.
Extinct in the wild - these species are known only to survive in human care.
Critically endangered - the species is facing an extremely high risk of being extinct very soon.
Endangered - a species is in danger of becoming extinct.
Vulnerable - the species is not yet classified as endangered but numbers are continuing to drop.
