A Chicago Tribune correspondent embarks on a mission to trace the oil from a service station back to its sources; the results are quite remarkable–enlightening and frightening and such–and are conveyed through a written article and an online video documentary (which, before you go, “aw, shucks,” has pretty remarkable production values).
(Also, the documentary uses some well-placed Philip Glass music from Koyaanisqatsi, which is a plus.)
