> develop standardised farming skyscrapers/towers to hydroponically grow food in Land use for vegetable farming is really not an issue. Just build your hydroponics setup on the ground, you'll cut costs by an order of magnitude. If you actually want to reduce land use, get people to eat less meat. The crops that use the most land by far are corn and soy, and most of those ends up just being fed to livestock.
