And have 'agreed' since tykehood in the observations of my very-own eyes: that our Kultur was/is one based upon profligate waste. The rest of the world has been easily seduced into the same mindset.
Nor was that merely my own myopic take - I could reel off the (unread) book titles from, even before Silent Spring. 'Population' - remember that one? You can be Lots sloppier in your spaceship if all the staterooms aren't full -- and the inmates start burning the 'trees'.
Humans are notoriously incompetent at estimating scale & relativity. This will be a ~ Final Exam on, your money or your life (?)

Decisions will be wrong, predictably; if most are of the same quality as manufactured Iraq - we're doomed. But they need not be. Still, we appear to have a vanishingly small window for education of millions/billions of the slothful about the Whys, in language a 12 yo can understand.
Since we've never before tried a crash program for Growing Up, well.. nobody knows if the species could turn away from the 24/7 entertainment long enough to learn how to ponder. Nobody knows that.
Wish ourselves luck - it'll take a lot of that.
