Yes, everyone subscribing to a CSA would shift the face of food production in the country, by instantly jacking up the price of food for everyone, drastically reducing the efficiency of the food supply system (local farms being for many obvious reasons far less efficient), plunging whole regions of the company into seasonal food "droughts" (as Northern families throw away bushels of beets and sweet potatoes and go to McDonalds instead), and increasing energy consumption.

I'm a CSA-eating locavore; I buy my protein from a whole-animal butcher who's on a first-name basis with the farmers who raise all his products.

It is a spectacular luxury, one I'm actually faintly guilty about.
