Question

multiple choice 2 points
desertification is primarily caused by which of the following activities?
overgrazing of livestock
overplanting of crops
overuse of farm machinery
lack of rainfall
restoration of wetlands

Explanation:

Overgrazing by livestock removes vegetation, which leads to soil erosion and degradation, contributing significantly to desertification. Lack of rainfall can be a factor but overgrazing is a more direct human - caused activity. Overplanting of crops is not a typical cause of desertification. Overuse of farm machinery doesn't directly cause desertification. Restoration of wetlands helps in preventing desertification rather than causing it.

Answer:

overgrazing of livestock
