Imagine an apple, rotten at its core, pocked with worm holes and brown, pasty insect excrement spilling out the side. Now imagine an apple free of insects but coated in lead and arsenic, like a candied apple of toxic metal. Which would you rather eat?
In the 1930s that was the orchardist’s dilemma. Succumb to the codling moth and its lust for apples, or fight the pest the only way you knew how.
Today, you don’t have to make that choice. And you have the banned chemical DDT to thank in part for that.
