Malaria is a great example. The USA used to have endemic malaria as far north as New York. It was eradicated by the CDC carpet bombing the country with DDT[1].

Malaria is a great example. The USA used to have endemic malaria as far north as New York. It was eradicated by the CDC carpet bombing the country with DDT[1]. Was that a good thing? I’m inclined to believe that on the balance it was, but there’s no denying that mass spraying pesticides had negative consequences. The question then is how do we determine if that action was justified? [1] https://www.cdc.gov/malaria/about/history https://www.cdc.gov/malaria/about/history
