The model puts the maximum amount of natural resources at 1900 and then has it continually downtrending. That’s malthusian and peak oil nonsense. You also just cited a peak oil book when you copy/pasted from the ‘validation’ portion of the wiki page. Malthus and this book are linked on wikipedia.
No it doesn’t. It simply points out how literally every prediction of disaster based on Malthusian thought has been wrong since 1798. Maybe this one will be the one, but given it’s already failed to predict the gradual slowing of the world’s population because people are simply choosing to not have tons of babies that is happening right now, it seems super unlikely.
