Quizplus · Accepted Answer

Livestock grazing is the primary cause of desertification in North America's drylands. Overgrazing by livestock leads to soil erosion and a decrease in plant cover, which contributes to the loss of soil nutrients and eventually renders the land barren. Plowing for crop production and fires may contribute to soil degradation, but they are not the primary causes of desertification. While global climate change can exacerbate the effects of desertification, it is not the root cause.
