Answer:
One way in which humans contribute to desertification is through overgrazing. When livestock, such as cattle, sheep, and goats, graze excessively on vegetation in arid and semi-arid regions, it can lead to the degradation of plant cover and soil erosion. This overgrazing reduces the vegetation's ability to hold soil together, making it more vulnerable to erosion by wind and water. As a result, fertile soil is lost, and the land becomes increasingly arid and prone to desertification. Overgrazing is a significant human-induced factor that exacerbates desertification in many regions around the world.
