Answer:
Although pesticides can help a farmer to get rid of insects that are harming his plants, but pesticides can be heavily toxic.
Some of the dangers of using pesticides are:
The pesticides can make their way into a river, lake or pond source. They can be toxic for the aquatic life there. In this way, they can make an ecosystem unstable.
Leeching can occur when pesticides make their way to groundwater. The groundwater is used by many people for drinking purposes. Hence, this water will become toxic for the usage of humans.
