neat article on "food miles"

My co-op newsletter had a an article this month entitled "The Surprising Truth about Food Miles".  This has information on what are the most environmentally/ecologically sustainable foods at any given season.  There are a lot of things that go counter to your intuition, so it's worth a read if you care about that sort of thing.  For example, bananas from South America aren't as bad as berries from South America, because they aren't as perishable and don't require air transport.  But berries from the US in season aren't as bad as berries from South America.  It's berry season now and I'm eating them up every day.
