<i>Now either the grocery store or the consumer who uses the plastic bags have to pay for the pollution they cause.</i><p>Except this pollution isn&#x27;t really caused (the example being given over and over are bags blowing in the wind) if people dispose of them properly.<p>That is no longer covering an externality, that is punishing the many for the careless actions of the few, something that is always immoral all of the time in my mind.<p>Fine the litterbug companies and litterbug people, leave everyone else the hell alone.
