Your bad knowledge of English, and the fact that you mainly read information in english, may explain why you make error after error. Your last two bolded sentences shows this; my sentence means the reverse of what you think it means. Anyhoo, over to the malaria deaths again:

First off, the number of sources do not matter, it is the quality of sources that matter. For example, quoting a hundred tv-stars has far less weight when discussing psychology than a single quote from Freud, for example. When it comes to world statistics, we have two sources who rank far above the others, that's the CIA and the UN. If you didn't know, the WHO is a part of the UN.

First of all, two of your sources are one and the same, and the figure comes from a WHO (meta)study in 2001. I have already noted the spike in the years around 2000, that's where that number comes from. The guardian article refers to a brand new study, and we will have to see in the next WHO report how credible it is. You should've read it more carefully, however, as it in no way supports your 1-2 million figure. The last is a study which only mentions death toll as a spice in the intro, and is about something other than death toll(it's about pregnancies). Thus, it's not a source for this purpose.

DDT was never used in tropical areas(on the same scale as in countries like the US) before the ban, as it was considered ineffective in such areas. It worked wonders in temperate zones, but there's a huge differences in the climate for mosquitoes in tropical and temperate areas. What works one place may not work in another. DDT was not found to work in tropical zones, and so was rarely used. Probably because of its limited use, the governments in many tropical nations saw no need to ban it, and so it has remained legal. I see no reason for me to write more on this, however, since this is something one should expect you to find out on your own, given the certainty with which you present your (poor) arguments.

AND STOP YOUR DAMNED BOLDING

It does not clarify. It does not highlight. It obscures, and makes your posts even harder to understand than they already are.
