Though I would expect that from "militiaman21" ;-) However, the local food movement needs to talk more about yield. It doesn't appear that humanity can sustain itself this way - small communities perhaps, but it's a first world luxury. Also, "food miles" is a BS metric, the biggest energy sink is fertilizer (by far!). Ammonium Nitrate is made by fossil fuel + air - you are mostly eating energy from natural gas, not the sun, it would seem.
