Oh, it’s unacceptable. We must do everything we possibly can to prevent environmental catastrophe and a potential mass extinction event. It’s probably better not to even accept the possibility we may fail. For my mind though, the stakes are too severe for me not to consider how thinks could still be ok long-term (centuries to millenia) we could recover from it. This is what I would be thinking about while I’m dying from exposure. I would much rather not have anyone go through it.
