It seems that many people here are making conjecture based upon little research. Vertical farms are very much possible and actually relatively efficient . The EPA has been funding small scale pilot farms to test the concept. The engineering hurdles which people are describing have mostly been dealt with. Food from these farms may cost more but it is fresh, local and organic instead of ethelyne ripened and full of pesticides. Take a walk to whole foods and you'll see that people are willing to pay for that.
