How Do Pesticides and Fertilizers Cause Pollution?

Pesticides and fertilizers are widely used to increase crop yield. However, their excessive use can lead to severe pollution. When it rains, these chemicals can leach into nearby water bodies, causing eutrophication, which depletes oxygen in water and harms aquatic life. Moreover, some pesticides are persistent organic pollutants that remain in the environment for a long time, accumulating in the food chain and impacting biodiversity.
