Cutting the forests bring disaster

Storms, tornadoes, floods, landslides, droughts, and many more are caused directly by the disappearance of forests.
Forests, the "green lung" of the planet, who purifies the air and gives us oxygen and that is to keep alive the planet - our ecosystems, our home.
From trees people use wood to build houses, furniture, firing fuel, and other. But in the same time, cutting wood from forest will bring a ecological holocaust.
