Third world population growth is a massive threat and problem. The hordes of Africa are already swarming into Europe.
You have misidentified the problem.
We have refused to let the nations of Africa develop self sufficiency, because “we” don’t want them competing for their own natural resources.
Meanwhile, Europes socialist and abortive policies have both reduced native workforce growth and promised gov’t checks to immigrants.
Europe also has failed to distinguish between Christian and Muslim immigrants, at the same time doing nothing to stop Muslim persecution of Christians in Africa.
