Yes, it’s already too late. To paraphrase...”Hang on, we’re in for a bloody ride.”
I agree with you that human nature doesn’t change much, if at all, or certainly not on a timescale relevant to this discussion, and I know many of us are cynical about our prospects, but isn’t there any chance of repairing/restoring all of this? I suppose if not, I should better spend my efforts on a bunker and ample fortifications, and huddle waiting for the end.
See what I mean?
