Andean bears, tigers and orang utans could disappear from the earth in just 20 years, according to wildlife experts.
Gone forever
Hunting and chopping down forests have driven these animals to the very edge of extinction, so that one day Paddington in a book might be all that's left.
To try and stop it happening, the Discovery Channel's launching an Adopt an Animal project with an eight-hour extravaganza to be broadcast around the world..
It's to raise money for endangered species.
Viewers will be asked to pledge money through special wildlife charities.
It will be shown on 25 November.
