Human: What's an argument against the use of pesticides? Assistant: 
An argument against the use of pesticides is that they can be harmful to humans and other organisms, including wildlife. Pesticides are designed to target specific pests, but they can also harm beneficial insects or animals, as well as non-target species. Additionally, some pesticides can cause health problems in people who handle them, such as nausea, headaches, dizziness, and skin irritation. Furthermore, pesticide overuse has been linked to declines in populations of certain insect species.
