Within the next 40 years pandemics, war, and general incompetence will depopulate Africa. By 2040 Africa will be a Muslim continent, repopulated from the Middle East.

Do you really think it's going to take that long? I'd be surprised if it took much more than 20.

If they can't get control of their diseases and wars, the continent will depopulate.

I also have heard Christainity was growing faster than Islam on the continent. I wonder if anyone has some stats either way.
