Rachel Carson is singularly responsible, whether she intended it or not, for the deaths of millions of people in sub-Saharan Africa.
The pesticides she decried in her book were at the time, and perhaps still remaining, the only effective treatment against mosquito-borne malaria and other diseases. Nets, which are the current alternative treatment, are of course ineffective if one happens to be outside, and not particularly effective inside.
While it may be true that many other species than the target mosquito are affected by such powerful poisons, it remains also true that the choice is between species other than Man, and innocent and unprotected native populations.
A hard choice, but one in which we may have decided the wrong way.
I would remind all of us that Nature has a solution for any problem Humanity faces, but we may not find Her solutions to our liking, or even our ability to survive. We are currently attempting to survive under some of those restrictions.
