Food affordability, United States

Because of these problems, and also the development of DDT-resistant strains of insects, DDT was banned in the United States in 1973 and has since been banned in other countries in the developed world. Alternative insecticides are available, such as organophosphates, but they cost at least three times as much as DDT. The developed world has the luxury of choosing to use these, as it can pay more for the food which they help protect and for a pleasant environment. However, in the Third World the nations resources are so small that even DDT can barely be afforded. It is therefore still used on a large scale in these countries.
