This will probably go over like a lead balloon, but there is something to be said for natural selection. NOW BEFORE YOU START SCREAMING, hear me out...
AIDS is an awful thing, especially to the proportions it has affected the people of Africa. But there is also a reason AIDS has taken over there the way it is, and it's only partially to do with poverty. AIDS has exploded in that population, because it is a population that is extremely traditional, rudimentary, and in many ways archaic. There are many wonderful things about the African people, but there were also many wonderful things about the Dinosaurs, the Dodo bird, and numerous others.
Please don't take this to mean I'm equating the people of Africa with wild animals. I'm not. But in many ways, the people of Africa are in the situation they are in because they have not evolved the same way as most of the world, and in that respect, they are paying a price. Yes, it is our responsibility as human beings to try and help people in need, and that is a wonderful thing. But at the end of the day, if we did nothing, there would still be a small percentage of African people who will survive this epidemic, and they will be more educated and elightened than the ones who do not.
Much in the way that forest fires, although terrible in some respects, are essential to the rejuvenation of the population and ecosystem in that area, so too are epidemics and catastrophes. And this not a bash-on-Africa comment... the Black Plague was the same idea. Too many people, living in too close quarters, with too little regard for health or wellbeing. Millions died, but many survived, and the ones that did were smarter and wiser for it.
The people of Africa are not necessarily as helpless as the may seem from the outside. They just have a different culture and mindset than Western people do. Right or wrong is not for us to decide, but adapting to nature is part of life on Earth... and sometimes that means that large numbers of people or animals die, needlessly or otherwise. Just my two cents.
