Pesticides are poisons: they kill the particular pest that they are intended to kill, but then they seep into the soil or into water systems, where they can kill other needed insects, can be ingested by fish or other aquatic life, and from there be ingested by birds or larger animals. A buildup of residual pesticides in a given area can do tremendous damage to the entire ecosystem.

∙ 14y agoPesticides are intended to kill insects, but any substance that is poisonous to insects is also going to be at least somewhat poisonous to other kinds of animals as well, including human beings (which are in a biological sense also animals). There is no poison that is only poisonous to insects.

∙ 13y agoPesticides are any substances that are used with the intent to prevent, destroy, or repel pests.
The hazards of pesticides include the fact that they often affect other species besides the one that they were intended to repel, they can be carried by the wind and contaminate other areas, pollute water, reduce biodiversity and nitrogen fixation, and cause health effects in humans such as birth defects and possibly cancer.
