Excessive use of chemical fertilizers and pesticides can lead to:

The correct answer is: All of the above.

Excessive use of chemical fertilizers and pesticides can lead to soil pollution, water pollution, and loss of biodiversity.

• Soil pollution occurs when chemical fertilizers and pesticides are washed away by rain or irrigation water and contaminate the soil. This can make the soil less fertile and can also harm plants and animals that live in the soil.
• Water pollution occurs when chemical fertilizers and pesticides are washed away by rain or irrigation water and contaminate surface water or groundwater. This can make the water unsafe for drinking, bathing, or irrigation. It can also harm fish and other aquatic life.
• Loss of biodiversity occurs when chemical fertilizers and pesticides kill or harm plants and animals. This can disrupt ecosystems and make it difficult for plants and animals to survive.

It is important to use chemical fertilizers and pesticides carefully and only when necessary. It is also important to follow the directions on the label carefully and to dispose of them properly.
