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.
Soil erosion and the loss of soil fertility is caused by the marginality of the available slopes and the methods used in farming. Cultivation techniques are slash-and-mulch or slash-and-burn employing simple tools, such as machetes, hoes, axes, digging sticks, and possibly wooden plows, without the use of fertilizer.
