How have human activities Affect agriculture?

Human activities have affected agriculture through deforestation, soil degradation, and water pollution. Deforestation reduces biodiversity and disrupts ecosystems essential for agriculture, leading to loss of fertile land. Soil degradation from practices like over-tilling and excessive pesticide use reduces soil fertility, impacting crop productivity. Water pollution from industrial runoff and improper waste disposal contaminates water sources needed for irrigation and livestock, thereby affecting agriculture.
