The whole idea behind “not sustainable” is that it is not possible to sustain something.

-1 That is not “the idea!”, that is the definition. A recursive one at that.
-2 That doesn’t really follow from either your or OPs comments. What is not sustainable? The economy, society, global trade? Did you delete a sentence?

I think your comment makes more sense if I was arguing for people to counteract population decline. I am not. I was simply pointing out that it won’t be sunshine and rainbows as OP and many commenters here seem to believe.

Considering how people struggle with the comparatively small hiccup that is the current Iran-US war, I find it hard to believe that all commenters here would be fine when global trade dwindles.

I however am built different and would simply survive economic and societal collapse.
