I already documented that using known productive methods, the earth can feed 60 times the current population, just using habitable land. If we put people into nonagricultural areas, vs pretty flatlands, turned agricultural practices to things proven sustainable and intensely productive, things would change for the better. Doing so would also take pressure off the oceans as food source.
I did NOT say it would happen. It's also known, researchable, and documented that 1 acre of modern vertical gardening can feed up to 60,000 people, using the same high rise technology we use to build cities, meaning we could even support 120,000 times the current population, just on that same 2+ acres per person of habitable land, and even more, with strategic relocation to nonagricultural land, and reassigning land better suited to age purposes, instead of cities.
This can all be easily verified... Google is your friend.
