Forests stabilize the soil, preventing erosion and natural disasters.
The roots of rainforest trees and vegetation help anchor the soil. When trees are cut down there is no longer anything to protect the ground and soils are quickly washed away with rain. The process of washing away of soil is known as erosion.
As soil is washed down into rivers it causes problems for fish and people. Fish suffer because water becomes clouded, while people have trouble navigating waterways that are shallower because of the increased amount of dirt in the water. Meanwhile farmers lose topsoil that is important for growing crops.
