If everyone stopped, at some point it would become environmentally feasible (by some metric, I'm sure) to have offsprings again, in which case I would certainly amend my decision (clearly hypothetical, because I wouldn't be alive anymore by then). It's the same non-sense argument of "imagine if everyone invested in index funds". It cannot happen, because at some point the right arbitrage opportunity becomes too obvious to ignore. Here is the same, at some tipping point there would be so many resources available per capita that it would make complete sense to have kids again without screwing up the environment. All the downvotes simply prove, in my opinion, that people get really offended when confronted with the uncomfortable fact that having kids is, by far and on average, the single most negatively impacting choice they will make on environmental resource consumption in their lives, but they'd rather blather about not taking that one flight or eating organic quinoa for lunch, missing the forest for the tree. I don't blame anyone for that, it's very much biological.
