Ding, ding. The math has to be done on a case by case basis. Why are all potatoes grown in Idaho? Because soil and climate conditions there are really good for potatoes. You can grow potatoes in Idaho and ship them to Kansas for less -- less land use, less effort, less energy-cost, less environmental impact -- than you can grow them locally. There are going to be some crops and some urban environments where vertical farming is the best option. There are going to be some where it is not.
