Europe’s big problem is the hindered of millions of climate refugees on the doorstep. Even the most open heart liberal will baulk at the population doubling or more in 20 years. The only ones promising a solution will be the neofeudalists
Every region, culture will need to find a path to sustainability in their own way. If the path they take is invading another region, it leads to war. Like it has been for thousands of years.
But this is what we are doing anyway...
I am just trying to articulate a path where can have better food security and sustainability.
No liberal would want millions of people coming from Afghanistan, for example.
But when it’s the best part of a billion people - at a rate of 4:1, that’s a different question.
Leaving aside what you hear on the internet, I personally know a few people who say they have no concern welcoming any number of refugees, a couple of them actually to the point of getting quite enraged at people who do have different opinions. So there definitely are some such people in existence.
