More good Pollan in the NYTimes mag yesterday, which many others will note, surely.  But I want to underscore one of his most important points.  That eating locally is not a romantic mandate from the Alice Waters camp, and that its impact goes beyond the pleasures of eating seasonal foods and helping out the local farmers, and that it goes beyond reducing the fossil fuels required to ship, say, spinach to New York, which is a main point in his recent book.  It  is this:  “Keeping local food economies healthy—and at the moment they are thriving—is a matter not of sentiment but of critical importance to the national security and the public health, as well as to reducing our dependence on foreign sources of energy.”  National safety and the public health.  Our food supply is dangerously centralized, and I will do everything I can to urge people to do all they can to ensure their local food economy continues to thrive.
