Now it's becoming a stage for some of the Cold War-ish struggles between Russia/China and the US. Hopefully it remains mostly an economic stage where it's a battle of who pours more money into the continent's economies for friendship.
As of now, the population growth is already creating some very powerful migration pressures. Most of them stay on the African continent, but even the few per cent that reach Europe are enough to turn European politics full tilt to the far right. It doesn't help that Sahel, the most fertile part of Africa, is also one of the most arid - and Islamic at the same time, so a clash of values with secular liberal European societies is all but guaranteed.
The new Cold War will have a significant migration dimension.
So support local school systems with all might, which also means countering prejudice and religious bigotry of some locals. Once every girl has a chance to stay in school until at least 14 years of age, TFR will drop by more than half.
That sounds so much better and so much more humane (sarcasm).
