Perhaps some of those kids will become rocket scientists and help us get off this Earth and continue our relentless expansion and consumption off-world.

Also, isn’t immigration a negation of 1)? The kids are already born, they’re just not in the same country.

Sarcasm aside, there are two systemic problems at play. 1) is ecological, and 2) is economic. The second may be physically easier to solve- but it still requires us to figure out a way to move beyond our capitalist system that a) prioritizes relentless growth and consumption, and b) has countries with large welfare programs that requires new workers and taxpayers to keep the elderly and the ill off the streets.
