Paul ehrlich and “ZPG” comes to mind.

Paul Ehrlich rather famously lost a large bet with Julian SImon on resource scarcity.

Ehrlich is (he's in his 90's now) basically a Neo-Malthusian.

Bucky Fuller spoke and wrote extensively against Malthusian doctrine. Bucky pointed out how tools, machines, and other technologies allowed us to "do more with less"...

...which process he called "ephemeralization".

Bucky was right. Malthus et al are wrong.

“ZPG”! I remember those days. I also remember another book declared “racist” but is coming true today.
CAMP OF THE SAINTS by Raspail.
Originally it was blacks from Africa overrunning Europe. After a screaming fit by critics he changed the invaders to Asian Indians.

"Paul ehrlich and “ZPG” comes to mind.'

What was the point of sacrificing for ZPG back then when Obiden chose to import millions at the start of the 21st century?
