Will Africa exist in 100 years?

I just read this article in the Atlantic Monthly about how civil war in Congo is destroying the ecosystem in that part of eastern Congo near Uganda (which still hasn't visited here, although I kid you not I've been getting more hits from France than from here, but anyway...) The article said that all the fish have been fished out of the lake, the elephants have been killed, and the hippos are losing population, resulting in more hunger and more overuse of the limited resources. The author, Delphine Schrank blames the war:

By now, the internecine wars of eastern Congo have acquired a haunting familiarity: rebels plunder the country’s natural riches, and the looting feeds a cycle of impoverishment, corruption, and violence. But in Vitshumbi, more-elemental changes have been complicating the pattern. The hippopotamuses started falling first. Then the elephants. And now the fish are disappearing, too. An ecosystem seems to be unraveling.

It sounds horrible. But don't sentences like the following seem all too common?

And so the villagers have been forced to eat the small, bony fish that they once would have tossed back into the water as trash.

I'm pretty sure this isn't the first time this has happened in Africa. All I think about in Africa is AIDS, malaria, famine, and desert, which btw is expanding every day and is like gonna reach South Africa soon. I have read stories about the diamond trade being run by rebels in wherever, who basically expolit the people who live there, who don't receive the benefit of living on top of like, a diamond mine, and are also starving.

I think in the future, everyone in Africa will either have left/be dead and the continent will be a barren wasteland. What are the roots that clutch, what branches grow out of this stony rubbish? None. In the future people will visit Africa and take tours of the places that were once inhabited, like the 'mids. In the future Africa will be the failed continent. In the future the buildings in the cities might still be standing, but there won't be anybody in them. What do you think?
