I guess the EPA considers it no big deal that we are still using older more dangerous pesticides while better ones sit unused. The reason people advocating sustainable agriculture usually frown on liberal pesticide use is that the pests can grow resistant. Currently, more than 200 species of insects are known to be resistant to one or more insecticide. There will always be a need for insecticides, especially as more people demand foods from less cropland. However, perhaps alternative pest control methods should be utilized besides just chemical applications.
Vertebrates are also pests.
Rabbits, moles, raccoons, rats, and many other mammels feed of agricultural products. Hunting , trapping, and poisoning is required to reduce their impact. Birds are also a major problem. They feed on seeds and defecate in the seed storage areas. These seeds are then feed to animals or people who can become ill from it.
