I think we are talking past each other, and that part of the problem may be that you are unfamiliar with what ecosystem management actually is[1]. I agree with you about malaria and spraying DDT. I caught and endured through malaria when I was doing field work in Tanzania. But, the WHO also agrees with you about spraying, and I personally feel this is a much less controversial issue than you make it out to be. Spraying continues to be funded by USAID, and I have found no indication that the current administration plans to change that. It's very nice, I'm sure, that the WHO and company admitted their mistake ... 3 decades later and how many 10s of millions needlessly dead in what is easily one of the 20th century's biggest genocides? It's not that simple and if you have read the Wikipedia articles on DDT, which you say you have, you know it. If you want to engage in a rational, reasoned discussion, I am happy to do so, but if you want to spout hyperbole like this, go fly a kite because I am done.
