That's true for now, although their rate of population growth appears to have peaked several years ago and like most other countries the birth rate has since declined sharply.
People born yesterday are alive today and will be alive in the next ~70 years mostly.
Given this unsustainable population growth, I wonder how serious the refugee issue will become for Europe and the Americas over the next 30 to 40 years.
How is that even sustainable, like housing, education, electricity, running water, etc. how can they scale those with that fast growing population
Grow more crops, build more dams, etc?
Until they are out of room anyway, but they have a lot of unused desert right now.
Typically, people produce about as much as they consume, so a growing population normally sustains itself.
