Biodiversity Of Rainforests
Over 50% of the Earth's species live in tropical forests.
Tropical forests contain 70% of the world's vascular plants, 30%
 of all bird species and 90% of all invertebrates.
90% of all primates are found only in tropical forest regions of Latin America,
Africa and Asia.
In Brazil's Atlantic Rainforest, 70% of its plants and most of its 20 primate
species are endemic.
780 tree species have been found in a 25 acre plot of Malaysian rainforest--
more than the total number of tree species native to the US and Canada.
