The decline of the forests

Every second an area the size of a football field in the rain forest around

the world vanishes.

Rain forests covered 14% of the earth’s

surface. But by now they cover 6%.

The experts believe that the rest of the

rain forest will vanish within the next 40

years.This image provided and copyrighted by Raintree Nutrition, Inc.

Over half the species of animals, insects

and plants will vanish because of

the destruction of the rain forest..

137 species disappear every

day. This amounts to 50,000

annually.

121 medications are being created by using the plants of the rain forest but only 1% of

the plants have been proven by scientists.
