The document discusses the negative impacts of pesticide use. It defines pesticides as poisons used to kill pests that harm plants, animals, or humans. The main reasons pesticides are bad are that they are harmful to human health, contaminate water sources, and some pests they target are not actually harmful. Pesticides can cause various cancers, developmental issues, and acute symptoms. They also negatively impact wildlife and aquatic environments, killing millions of birds and fish each year. The widespread use of pesticides results in millions of pesticide poisonings and deaths among agricultural workers and the general public annually.
