Yes I can see that. But you don't seem to have thought this through very well. If sprayed promiscuously as the Americans did, how much DDT would even the smallest third world tropical country need to make a dent in malaria rates? How much acreage would have to be oiled (and thus destroyed as a habitat) to do the same? Assuming they could afford it financially, how would they afford the ecological costs? Remember, many of these countries don't have industrialized agriculture to insulate them from damage to native habitats. And forget oiling wetlands -- that's not how the Americans did it. Americans did most of the work by draining wetlands near populated areas. So tell me how that would work in a country like Nigeria? I'll give you a hint if you need one. There are many intelligent ways to fight malaria. Exporting some clumsy, ham-fisted methods that Americans rejected forty years ago is not one of them.
