It’s worse than that in numbers, there are more than one million deaths per YEAR due to malaria worldwide (most in Africa)....
Assuming estimates are accurate that proper ongoing use of DDT could have eliminated most deaths from malaria, Rachel Carson and her gang have allowed 10s of millions of preventable deaths in the past 50+ years.
I suspect DDT was banned for the same reason FREON was banned:
1) company makes a product- it is the best known product of its type.
2) company makes a fortune off this product
3) the patent is expiring, and soon anyone can make it.
4) company gets it own product banned, so company can introduce and sell ...
5) ...new company product. Not as good as origianal, but just as profitable.
And it turns out that in Africa the mosquito nets that do-gooders have sent over there are being used to catch fish. And the nets work so well that now the enviroMENTALists are complaining about overfishing in the area.
