Vertical farming is believed to be the future of agriculture because it allows people to grow crops in upright trays and save precious land space for other human activities.
uhhh this sentence is wrong but yea
the least damaging "human activity" on land would be some type of traditional farming, the only thing "less damaging" than that would be letting it return to wilderness, which is not a human activity
To be fair, if we did confine farming to sckyscrapers we could use the vast amounts of land traditional farming occupies for parks, nature restoration, and so on. And China has been doing most in terms of rewilding globally, so there is that.
okay but the only thing you'd be able to grow is lettuce and herbs. It's nice saving the amount of space those take up I suppose, but it's not a farming revolution either
