Many of these items (plastic and paper cups, utensils, napkins) are so cheap to produce that they automatically come with our food—even if we don’t want them to. As a result, we view these “free” materials as nearly worthless, and they go from single-use resources to “zero-use” resources: how many times have you received a straw with your drink that you didn’t use, or a clean napkin that you threw away with the rest of your meal?
