Pesticides can degrade the environment in many ways:

i)             When pesticides are sprayed in the air, it can cause air pollution.

ii)           Sometimes, pesticides remain in the soil for long periods of time and thus cause soil pollution.

iii)          In many cases, the excess pesticides get washed off and reach the water bodies. Here they cause water pollution and affect aquatic life. These pesticides may accumulate in the food chain and cause biomagnification.
