Every choice has costs we bear, and costs we don’t. Often, the negative externalities of our choices outweigh any perceived benefit. For example, a plastic, or even worse, styrofoam, plate is useful for maybe ten minutes while I eat, but then can take thousands of years to degrade. But others will bear that cost so I can avoid doing dishes.
Most of the time, we humans are adept at avoiding thinking about these externalities and who is on the receiving end of their bill.
