This evening I stopped by D2E, otherwise known as down:2:earth, Boston’s Sustainable Living Expo. D2E has about hundred exhibitors regaling visitors with organic wine, electric bicycles,  properly insulated windows, cloth diapers and other terribly necessary components of modern eco-conscious consumption, if there is such a thing. It’s fairly small as these things go– it could probably fit in your high school gym–and lacking in the relish-and-mustard-sellers-with-free-pretzel-sticks that you’ll find at the Boston Flower and Garden Show, but there were a few exhibits worth seeing.

For me, the highlight of the show was the Boston Latin School Youth Climate Action Network’s display on the Boston Latin School’s Green Roof project . This green roof isn’t just a bunch of sedum stuffed into a pile of rubble; it’s an enormous project involving a greenhouse, outdoor classrooms, food production, and a bunch of other stuff. The youth have gotten at least twelve partners to work on the “roofscape,” including The Food Project and Studio 3G architects, and someone has put together an enormous amount of research supporting their goals. Go to the site and tour the roof-to-be. The more I looked at it, the more I thought, “Of course! This is exactly what urban schools should be doing!”

The BLS students on duty at the booth on Friday night were professional and cheerful. I sincerely hope that someday they’ll grow up and rule the world. You can help that process along by voting for them to get a “Green Heroes Grant” here on Facebook.

But wait!  There was more than one booth at D2E, really. I’ve already posted about Risa Edelstein’s charming birdhouses and nests. They were just as enthralling in person as on the web. Greenologist will take orders for farmers-market veggies and deliver them to you. (I wish Stop&Shop hadn’t taken the name “Peapod” first.) The Art for Water sculpture 13,699 consists of 13,699 bottle caps dangling from filaments to represent the number of people who die every day from unsafe water–but my children were entranced by the space, the shape of the caps that floated in air. If you’ve been curious about the fate of the McAllen Building, the subject of the documentary The Greening of Southie, suffer no more: Campion and Company realtors are on hand to sell you as much of the place as you can afford.

I also picked up a copy of the Spring 2010 Edible Boston, which is chock full of information on Boston-area farms and farmer’s markets, and features a terribly handsome chicken on the cover. I wonder, will the Boston Latin School’s roofscape feature a coop?
