What are the effects of pesticide use on the environment?

Pesticides are used to control pests that threaten crops, but their impact extends beyond the target organisms. Pesticides can contaminate soil, water, and air, posing risks to non-target species, including beneficial insects, birds, and aquatic organisms. Persistent pesticides can remain in the environment for long periods, leading to bioaccumulation and biomagnification in the food chain, which can have harmful effects on wildlife and human health.
