How does overgrazing contribute to desertification?

Overgrazing occurs when livestock consume vegetation faster than it can naturally regenerate, leading to soil degradation. The removal of plant cover reduces the soil's ability to retain moisture and increases erosion, which depletes nutrients. This loss of vegetation and soil quality can create a feedback loop, where the land becomes increasingly barren and unable to support plant life, ultimately contributing to desertification. As fertile land turns to desert, it diminishes biodiversity and disrupts local ecosystems.
