A tropical rainforest can be characterized by its evergreen layered or stratified vegetation structure, high biodiversity with a high and usually closed canopy 30-50m above ground level and it has no "seasonality- - no period of slower growth due to changes in climate.
             Hundreds of years ago, tropical rainforests covered 20 percent of the Earth's land surface. Now the forests have diminished to a mere 6 percent. Rapid deforestation is causing us to endanger this nature splendor and its many inhabitants. Nearly 500 million people depend on the forests for their livelihood and there is a growing concern about the accelerated rate of destruction of the remaining rainforests.
