Man, you're completely wrong. The Earth doesn't have a population limit. 8 billion is no closer than 1 billion. We can all live comfortable, luxurious lives. The problems we're facing have nothing to do with resource exhaustion (aside from petroleum), but inefficiency and pollution. We can absolutely produce goods without air pollution. We have sources of essentially limitless energy. We can absolutely use nuclear reactors to ship goods - no need for bunker oil. It's a question of economics and political engagement.
Cool. Get back to me when you've convinced the world to put a potential nuclear meltdown in every town and every cargo ship and drive EVs so they can use it for charging. Back in the real world, CO2 levels keep going up, up and away as countries like China go modern. After that comes India, Brazil and the rest of the developing world. Even if the population boom has subsided we'll still hit 10 billion people, that's another 33% growth.
The people who talk about reducing emissions are smoking crack, we're likely to double the world's CO2 emissions in the next 40 years if the technology doesn't evolve. Make that quadruple if everybody decides to pollute as much as Americans, because if they can why can't we? Whatever improvements we make will only make the explosive growth slightly less explosive unless we invent a working fusion reactor or something. Say what you want about nuclear but in the public opinion it's beating a dead horse. We're shutting existing reactors down, not building new ones.
