My carbon footprint response

Do you ever wish you could respond to some inane comment you've heard by ripping out a newspaper article and taping it to the perpetrator's mouth?

A co-worker scoffed at the suggestion that we consider our carbon footprint for a particular task. "I don't get what's with this whole carbon footprint thing," co-worker said. "It's all just a bunch of fluff."

Here's the article I would have liked to use to tape her mouth shut: "What's Your Consumption Factor?". Or at least clean out her ears with it.
