... make them so expensive that people will stop using them. Maine is the nanny state of nanny states.
We probably have a dozen canvas tote bags at home from various regattas and what not. I admit that I probably would be doing the environment good if I kept a couple in my car for grocery shopping. But nope, I take my groceries in plastic bags. Shame on me, right? Well, not quite. We re-use these bags in a number of ways -- mostly for trash and returnable bottles on the boat, and to dispose of cat litter at home. Friends use them for doggie poop when they walk their dogs. I've heard of people who use them to hold soiled diapers (yes shame on them for using disposable diapers right?). IOW, we used them to properly dispose of waste and prevent the sort of thing that the video laments.
Long story short, most everyone I've heard of who takes their groceries in plastic bags re-uses those bags for other stuff. From a nautical perspective, if plastic bags are eliminated, what are we supposed to use to hold trash and empties on the boat? Or do we just throw that stuff overboard sans bag and make the problem described in the video even worse?
