Africa is not ready for its current population, in 1950 Africa had about one half of the population of Europe, It is an extremely wealthy continent, in 1960 it was still exporting food.
Mass migration to Europe is not an answer.
Imagine a bigger sized country such as Germany or France taking in just 1 pct. of the current African population (that would be about 12 million). I guess one can expect that this would massively change such country beyond recognition, while not changing absolutely anything for Africa.
By such maths alone - the current wave of unvetted migration to Europe is a dead end that will not bring absolutely anything good for Africa (and for Europe with that respect).
If the population growth isn't curbed, it will be game over soon.
