Actually, "urban farms" are a growing trend. More and more people are giving up on the animal products and/or buying as much locally sourced organic or "grown with organic methods" as possible. Smart people are giving up their 2nd day job to grow food. Modern agriculture is really more of a problem than a solution but I do agree that to feed our large populations we need to keep the best of the modern technology and apply as much of it as you can to organic and more natural practices.
