RAINFORESTS :WHAT ARE THEY ?

They are forests that make up about half of the Earth's total forested area .

RAINFORESTS:How they look

Three layers :

* The upper canopy

level * Middle layer, * The forest

floor

More plant and animal species than any region.

Most productive ecosystems in the world.

Sixty % of plants on Earth,

90 % primates, 40 % bird species, and 80 % insects.

RAINFORESTS: PROBLEM ?

Logging Agriculture Plantation

Agriculture Hydroelectric

Power(Dams) Mining

RAINFORESTS: SLOWLY DYING ?

1960-1990 one fifth of tropical forest lost

1980-1990, 38 million acres lost.

1990-1995 ,34 million acres lost

RAINFORESTS: What can we do?

Stop cutting trees Plant trees that are

endemic (native) Control pollution Don’t over-harvest

(take too much ) Protect remaining

ecosystems

RAINFORESTS: CONCLUSION

Rainforests are disappearing faster than we think

Humans are responsible for forest loss

We will lose all our rainforests if we do not do something
