A really interesting food mapping project conducted by a group of Enviromental Studies students at Middlebury College.  The students built a series of Google Earth KML files that illustrated the spatial movement of ingredients that comprise a standard meal at Middlebury.  I’d love to see this expanded to a college (like Evergreen) that could trace not only food but equipment, materials, everyday consumables to the world market.  Match that to embodied energy and you have a much more definite idea of the real global footprint.
