The folks at The Splendid Table are conducting a survey of people's concerns about and interest in sustainable foods. You may already have a strong opinion about this. You may not have any opinion. But the survey is worth taking if only because it forces the issue: by which I mean, you'll find out real fast just how much you do or don't care, and how much you're willing to to do buy and eat "sustainable" foods.
I was, um, a bit surprised by my responses. Note: the survey does not ask about "liquid" foods such as beer or wine. Which is itself an interesting point. Anyway, the survey is here and it's worth look.
