Do you believe cutting down of trees from our forest affect the amount of rainfall in a country and does it have anything to do with global warming.

[Yoginitrish]

Yes. While I am far from a scientist, I know all these things are interelated. When forests are depleted, animals are without habitat, erosion and mud slides become real possibilities and I think rainfall is affected. Since trees and plant life have such an integral role in eliminating air pollution.

Deforestation does affect global warming because trees soak up carbon dioxide and effectively store it as part of wood fiber. When we cut down trees, fewer trees and smaller trees mean that less of the C02 is being pulled out of the atmosphere. At the same time, given that we are pumping so much C02 into the atmosphere, having fewer trees makes our excessive C02 production problem even worse. So, yes, trees are important to global warming.

As far as rainfall is concerned, trees are also very important. Trees effectively "exhale" water vapor into the air when the are breathing. They also shade the ground reducing the rate of evaporation. The combination of these factors affects humidity levels in the air which in turn affects rainfall.

I would also say yes. if we do have lot of trees, some water could be absorbed by them to avoid too much floods and the roots will hold the soil to avoid erosion. Trees also absorb CO2 and then gives out what we need which is oxygen. Trees could help us in eliminating some "warming"in our environment. They also provide shelter to some other living things.

Deforestation really affects the environment, as trees lower CO2 levels. But it causes erosion and landslides as well. I notice here in Mauritius that the more flora you destroy the more flooding it causes during heavy rainfall. More and more modification of drainage systems is required.
