Unfortunately, I am coming to agree that the chances of averting the collapse of civilization are approaching zero. Too many people are self-centered, intellectually lazy cowards.
Still, as noted in this article a better approach to the economy as a societal system is something to seek in the present that can perhaps survive into a future regeneration of civilization. I stumbled upon a way to make a single change to the existing economic system that would transform its impacts on society, including but not limited to sustainability.
If curious, there is "Overcoming Sustainability’s Single Biggest Obstacle"
To still try to save civilization there is "To Preserve What We Have, What We Have Must Be Enough"
Both are here in Medium, but not behind the paywall.
