Tacos, I think, are basically a perfect food. Variety in execution, simplicity in form. You can’t really improve upon that–unless, maybe, one were to map the geographic origins the humble taco. Students from URBANlab, a program of the California College of the Arts, traced each ingredient in an everyday taco from a truck in the Mission district back to its source, Good reports.
The idea was to map the local tacoshed; what emerged is a “surprisingly useful microcosm of the industrial food system,” Twilight Greenaway writes. “According to the class findings, within a single taco, the ingredients had traveled a total of 64,000 miles, or just over two and a half times the circumference of the earth.”
