Let me introduce the WWF (World Wildlife Fund).

It changed its name its name into World Wide Fund for Nature in 1980s.

The important mission of it is conserving the world's biological diversity.

And they also ensure that the use of renuable natural resources is sustainable.They promote the ruduction of pollution and wastful consumption as well.

Next I'll introduce the history of WWF.

It started in 1961. The British biologist Sir Julian Huxly made people know the seriousness of pollution.The businessman Victor Stolan stressed the need for International organization for conservation.
