Pluto is truly a well-trained dog. Like his master Mickey, he can get into a large amount of trouble but has enough brains to escape the situation. He acts as Mickey's sidekick, best friend, conscience in some occasions, and pet.
Deforestation causes some of the worst soil erosion. Forests keep soil where it is. The root structures of trees and other plants hold it in place, the natural mulch of leaves prevents soil from being exposed to the erosive forces of wind and rain. The canopy helps soften the impact of heavy rains.
One of the main causes of soil erosion is water erosion, which is the loss of topsoil due to water. Removal of vegetation is another cause or soil erosion and so is the removal of keystone species such as elephants from an area, when they are unable to fulfill their niche in the local ecology.
