Deforestation in South America

Deforestation in South America is where people are cutting down the forests trees. Some use the slash and burn concept then some us the timber effect. It's bad because if they use the slash and burn you cannot use the soil to replant the trees. Or to use the land for anything besides building on. Also so much wild life lives in the trees, they will loose their habitat. For the future they will run out of forest and natural resources.
If it pollutes the ecosystems water, then it effects the runoff. Then the runoff will go into the oceans and and on to the pollution.
