Reply to comment by KingVolsung in TIL that in 2003, scientists "resurrected" an extinct species of Ibex, bringing back one living specimen, only for it go extinct again seven minutes later when the specimen died of a lung defect by mausoliam95

Or you'd operate in low-oxygen environments via rebreathers, yeah. I'm not suggesting it'd be trivial, only that even drastic changes to our environment are unlikely to wipe us out.

Rebreathers are not sustainable, they require a supply chain to be able to keep using them. The scale of the supply chains required to keep humanity alive in such a situation is far beyond what can be achieved through bunkers.

The only way we could survive such a situation is where the environment will become survivable within decades, which in evolutionary/geological timescales is a blink of an eye.

No one is building and preparing bunkers for surviving centuries to millennia, because it's not feasible.
