This is an interesting topic, and I'm sure I will get flamed for pointing out that over 1 million people die each year in underdeveloped countries, of malaria. Malaria has been eradicated in the US and is easily prevented here. This topic was discussed yesterday on conservative talk radio and I think the point was well made....
IMHO, Rachel Carson has caused untold grief and suffering. She rates right up there with the worst dictators in that respect.
The US government is directly responsible for the resurgence of Malaria in the world because the USG banned the production and trafficking of DDT in this country and pressured other nations to do likewise.
