The traditional HN solution for Climate Change: If they only had more babies in the USA, their CO2 per capita emissions would fall and we would save the planet!
These 5th column arguments, are just appaling. USA (and EU, if we finally wake up and smell the coffee) don't have to pay for Asian high birthrates.
If a country has the same area as another, I expect that country to stick to the same total emissions.
China doesn't have to pay for it's high birthrates in the past? Well, then the West doesn't have to pay for their inovation and productivity in the past as well.
