How does vegetation protect soil and reduce overgrazing? why does deforestation occur in haiti? answers must be at least a paragraph☺

Vegetation can be assumed to reduce overgrazing of grasslands if it is woody vegetation. Woody vegetation would act as a physical barrier to grazers. The roots of vegetation, including grassland, bind soil together, thereby preventing erosion.

Deforestation occurs in Haiti because of a lack of energy options in the country. Haitians cut down trees for burning or charcoal production.
