This latest video from Jack Alpert is very good.
Alpert explains why on our current default trajectory most of the global population that lives after 2050 will experience starvation and that by about 2100 our 8 billion will be reduced to about 600 million serfs leading a medieval lifestyle on a sick planet.
Alpert then describes an alternate trajectory via voluntary rapid population reduction that avoids unnecessary suffering and preserves a modern human civilization of 50 million living on a healthy planet.
Alpert remains the only person that I’m aware of with a thermodynamically feasible plan for maintaining a modern human civilization as fossil energy depletes.
His plan does require us to break through our evolved tendency to deny unpleasant realities. A few, such as the readers of this blog, have demonstrated this is possible but scaling to the majority remains in serious doubt.
