Brief introduction of Tropical Rainforests
Tropical rainforests occur in areas of

https://en.wikipedia.org/wiki/Dry_seasondry season – all months have an average
https://en.wikipedia.org/wiki/Precipitation_(meteorology)precipitation of at least 60 mm – and may also be referred to as lowland equatorial evergreen rainforest. They rarely extend more than 10 degrees north or south of the

Mining and Drilling
-- Deposits of precious metals (

A simulation was performed in which all rainforest in Africa were removed. The simulation showed an increase in atmospheric temperature by 2.5 to 5 degrees Celsius.

Of Tropical Rainforests
Tropical rainforest conservation ranges from strict preservation of habitat to finding sustainable management techniques for people living in tropical rainforests. International policy has also introduced a market incentive program called

To keep the climate, we can take less car, reduce CO2, and we can plant more trees and flowers, produce less pollutes. We should try our best to use clean energy.
