If we think plastic is bad then wouldn't banning any of it be better than banning none of it? Wouldn't the answer be to ban more, not less? What's wrong with incremental improvements? We don't have to hit a home run on our first try.
Those are two pretty big "ifs" - people can be inclined to satisfice and pat themselves on the back for having done some minor symbolic thing, and then not go deeper. And it's much easier to sacrifice plastic straws than question whether your "bucket list" should really have a ton of carbon intensive global travel.
All we need is a seemingly copacetic catch phrase to bring the ocean-dumping not-recyclers into the light.
"Scamcycling"?
