Seems to me that made-to-your-personal-specifications food bars are a lot of things, but I doubt “green” is among them. Unless, conceivably, you live in Los Angeles, where they’re made and shipped from. I don’t even know that they’d meet a strict Michael Pollan-esque definition of “food.”
Note that the YouBar people do not appear to market them as being particularly green. Just tasty, which is fair enough.
