If space is the issue, let's note that one human requires 1-2 hectares of agricultural land, in production every year, to meet basic food and material requirements. Rail, air and ship transport can correct imbalances in food production and demand on a global scale, but only to a limited extent, as it costs energy - fossil, solar, wind, nuclear, etc. - to transport goods from point A to point B on the globe in a timely manner.
If often think, when reading articles like this, that the philosophers, economists and other social scientists all need to take remedial courses in basic thermodynamics, as applicable to physics, chemistry, and biology.
In biological terms, it's also undeniable that widely accessible long-distance air/ship travel has scrambled human population genetics like nothing else in the history of the human species, which is certainly a significant effect as well, with all kinds of implications for the future.

- imtringued 4y agoThere are only 1.5 billion arable hectares of land. There are people with ridiculously small plots of land which exclusively produce 150kg of rice that they eat. 2 hectares does not meet basic food and material requirements, it goes way beyond that, it includes meat consumption of at least one or two whole pigs. https://www.2000m2.eu/ https://www.2000m2.eu/
