What harm may result from excessive pesticide use?

Answer and explanation

Correct answer: Soil and water pollution

The governing concept is environmental pollution caused by excessive agricultural chemicals. Pesticides can move from treated fields into soil, drainage water, streams, and groundwater through runoff, seepage, or erosion. Their residues may harm beneficial insects, soil organisms, birds, fish, and other wildlife, while repeated use can also create resistant pests. Some residues may enter food chains and pose risks when exposure is high. Therefore, option A is correct because excessive pesticide application can pollute both soil and water. It cannot reliably increase rainfall, create mountains, or remove the natural salinity of oceans. Integrated pest management, correct dosage, protective measures, and safer alternatives help reduce these environmental impacts.
