Thanks for this. In my defence, re: sustainability, the last ch. addresses the next 1000 yrs, so 1962 pop. growth rate is irrelevant. No guarantee pop. will ever decrease. The limit of land vs potential unlimited pop. led to my concluding warning, simply a mathematical reality.
No it's not. A potentially unlimited demand [for land] and a demonstrably limited supply, over the course of a thousand years, is patently precarious.
