Another concluding excerpt from my reading of "Animal Vegetable Miracle," Barbara Kingsolver's 2007 book in which she and her family became locavores for a year.

The biggest shock of our year came when we added up the tab. We'd fed ourselves, organically and pretty splendidly we thought, on about 50 cents per family member per meal — probably less that I spent in the years when I qualified for food stamps. ... Our main off-farm purchases for the year were organic grain for animal feed, and the 300 pounds of flour required for our daily bread. To put this in perspective, a good wheat field yields about 1,600 pounds of flour per acre. In total, for our grain and flour, pastured meats and goods from the farmer's market, and our own produce, our family's food footprint for the year was probably about one acre.<br/>By contrast, current nutritional consumption in the U.S. requires an average of 1.2 culitvated acres for every citizen — 4.8 acres for a family of four. (Among other things, it takes space to grow corn syrup for that hypothetiical family's 219 gallonghs of soda.) These estimates become more meaningful when placed next to another proediction: in 2050, the amount of U.S. farmland available per citizen will be on 0.6 acres. By the numbers, the hypothetical family has change in the cards. [Page 343]

The first comment I could add is that the value of her family's labor was left out of the calculation! But I can relate: I often rave about my cooperative community garden and one of the first measures I use is how much produce we get for the $75 entry fee. We surely get more than $75 worth, but then again, we are in the garden at least twice a week, and we have website and educational commitments as well.

Sure we pay only $75 out of pocket, but we pay in additional ways as well. For the record, the recompense I get from this involvement also goes way beyond the food: knowledge, shared by my fellow gardeners who know what they're doing; the community of those who come to garden; the community of the public park and of the town where the garden is located; the legacy for my son, now 2, to learn that food comes from the ground, not from cellophane wrap.
