Either Europe is absorbed into Africa or at some point it learns, pitilessly, to say ‘no’. Neither alternative is likely to be remotely pretty.
The 21st century would probably be a good time to be somewhere else.
… two years ago the United Nations Population Division released a shocking update to their population projections, revising the forecast for the continent of Africa upward to 4.2 billion in 2100 from 1.1 billion today. […] That is about a half dozen times greater than the population of Europe. […] Africa is almost certainly not going to add over three billion residents over the next 85 years. Something else will happen instead …
For an example of how ugly it looks — in the eyes of polite opinion — to get anywhere close to realism on the topic, try this. It’s unthinkable! So, by far the most likely outcome is that Europe buries its head in the sand until it is already deep into existential crisis, then lurches into some new and even more hysterical version of its traditionally-favored fascist ‘solution’. Quite probably, it will get to lose another World War before the complete extinction of its civilization.
(If there’s a positive spin to put on this glacial catastrophe, don’t hesitate to share it in the comments.)
