Fruits and grains take a lot of area to produce a substantial crop. Grains have to be milled in substantial quantity to make it economical. Buildings have to reinforced to carry the load of soil, unless you're not doing some sort of expensive hydroponic deal. And growing in buildings? Have to ever compared a garden tomato with hothouse grown?

Rooftop/vacant lot growing of in-season veggies is a good idea, but will never be more than a supplement to the normal food supply. Our success with feeding over 300 million people is based on Mother Nature wiping out a crop over here doesn't devastate us because we're growing more over there.
