Can’t we do this in vertical farms, industrially, and not only take no more land from nature, but give land back. The more land we can return to nature the better.
From what I understand vertical farming really only works out economically for high value crops. Using artificial light instead of the sun takes a lot of energy, and tall buildings are expensive and require maintenance. Algae tanks would also be SUPER heavy, which is a whole other problem.
Buildings are still SUPER expensive, both up front and in an ongoing way. Personally I think it’s a bit misguided to promote vertical farms when we are currently wasting so much space to create e.g. parking lots, or to grow corn to burn in cars.
Tall buildings are good for housing people though.

It’s not ready, yet. But it could get started in places baking in too much solar.

Use old mines and go down. 😃 But yes, there are other land wastes we can go for right now.
