With Sub-saharan Africa’s population alone projected to rise by 3.5 billion to over 4.5 billion by the end of the century I share your concern. Europe and North American need to begin planning now for dealing with the migrant crisis which is just now in its very earliest stages. The environmental impact in Africa would otherwise be deviatating.

I have to expect upwards of a billion people from this region will need to migrate to Europe and probably an even higher number to the Americas.
