• At least 42 million acres of tropical forest are lost each year, an area the size of Washington State. This equals about 100 acres a minute.

• An estimated 50,000 species of plants and animals, mostly plants and invertebrates and mostly in the tropics, are condemned to extinction every year, an average of about 140 a day.

The forests of today are comprised of 50% boreal (mainly northern conifers), 44% tropical and 3% temperate areas.

The majority of the remaining forest that can be preserved is found in Russia, Canada and Brazil

While 25% of Western pharmaceuticals are derived from rainforest ingredients, less that 1% of these tropical trees and plants have been tested by scientists.

There were an estimated ten million Indians living in the Amazonian Rainforest five centuries ago. Today there are less than 200,000.
