Worldwide Fund for Nature

In this unit I learned many things about animals, for example these:
People love animals. But some of the world's animals are in danger of extinction. This problem is caused for man.
Another problem is the destructions of the forests. This is removing the habitat of many animals, like these gorillas, birds and plants.
But, there is an international organization, the Worldwide Fund for Nature. It looks at all aspects of conservation including animals, plants...

I think, this organization is a very big help for the animals of the world, also the people can visit this animals and have fun
