To be frank, and don't take this personally as I'm sure you're just honestly relaying what you understand, but I don't know that any of those stats are true. When it comes to the 3rd world I don't know if any stats are true. I figure it may all just be more propaganda either to get money or to serve some socio/political agenda.
I'm not taking it personally. No need to. But you should note that in my International Baccalaureate program (sort of a grade 13-14, if there was such a thing, that i had to take in the last 2 years before i came to the US) I spent a lot of time doing something called CAS (Community Action Service). And the facets i undertook dealt and delved into kids with cancer, the homeless aged, and the HIV issue. Unlike 99% of people on this thread I have seen what I am talking about. Unlike 99% of this thread I am not relying on statistics. And while I agree with you that many governments are using this as a political crutch, I also know that it is not due to 'malaria' or 'poor water.'
