> And if on top of that you are immigration-averse, you're effectively dooming yourself into extinction. The great majority of countries, even those with extremely low fertility rates (e.g. South Korea), are vastly more populous than at almost any other point in history. We're a long way from extinction - at least due to underpopulation. Meanwhile, a low population has a smaller ecological impact, and it's collapsing ecologies that are currently a bigger threat than running out of people.
