Maybe you can help with this. I seem to recall reading that Rachel Carson's research had been well and thoroughly debunked - she'd cooked the numbers, or something similar. Am I right or just imagining things again?
I'm no authority on Carson, and I can't tell you if she was completely debunked. I'm pretty sure they went from using DDT like it was candy to a total ban. After that raptors at the top of the food chain apparently had more eggs producing live chicks, but I'm no authority on the matter.
Too much environmental science has been politicized. I'm not sure if there are other better explanations of why eagle populations in particular recovered, but it seems to me they went from the sublime to ridiculous with the total ban of DDT and mosquito borne diseases.
