The UK banned single use plastic bags at major supermarkets. We all moaned about it for a few minutes, forgot our reusable bags a couple of times and then got on with it. Even the small plastic bags you put fruit or pastries in are now gone in a few super markets - initially, they replaced them with transparent paper-based windowed bags, but then I think people realised you really don't need to see inside the bag, and brown paper bags are back.
