how to change the culture to be more welcoming to immigration in the time of looming climate refugee crises
There are some estimates for 1.2 billion climate refugees by 2050 globally. No idea how accurate that is. But I do not believe there is any possibility of people somehow being convinced of accepting anything close to that. Even if wealth inequality and looming economic hardship wouldn’t undermine that goal.
PS: And yeah good point about population density in Sweden. I’m not sure how much habitable land there actually is though. I don’t think it really matters though.
