I've been a CSA member for years now and it is a source of pride for me (and envy for my friends, especially when I'm loaded with fresh fruits and veggies in the summer). Here, on food52's site, they list a number of new websites dedicated to helping those of us in urban environments get a little closer to sustainability by buying locally. They term it: "techno-locavorism."

Additionally, Martha Stewart just wrote an interesting article comparing "foodies" to "fashionistas." I don't completely agree with all of her points, especially the idea that the current push for sustainability/organic is simply "trendy" as her article subtly implies, but I still think that she makes a good point. I especially like the closing line,
"Like the classic little black dress, good food and entertaining keep evolving, but never go out of style."http://www.huffingtonpost.com/martha-stewart/food-is-the-new-fashion_1_b_821078.html
