Deforestation

http://www.aquapulse.net/knowledge/deforestation.html

Earth without forests is a picture that most of humankind presently could not conceive. Forests cover much of the planet's land area. They are extremely important to humans and the natural world. For humans, they have many aesthetic, recreational, economic, historical, cultural and religious values. Timber and other products of forests are important economically both locally and as exports.

http://members.aol.com/MJ232345/defcr.html

The tropical rain forest is the most diverse ecosystem found in the world today. It contains more species of birds, insects, flowers, trees, and other organisms than any other biome found on Earth. Unfortunately, with the growing population of humans the rain forests are being cut down at a terrifying rate to provide man with lumber, pasture land, and farmland.

http://www.geocities.com/prajna75/

The idea of this site is to convince the society that the reforestation of the planet Earth is strictly necessary.
