I wish they continued selling single-use bags and instead required them to be biodegradable/compostable. It's fine to charge for them, too.
Why? Because sometimes shit happens and you go to the grocery store without a reusable bag. You don't want to buy a reusable bag, you already have them at home. And those reusable bags are rarely recyclable or compostable either, so are they really greener than compostable single-use bags?
As I understand it, plastic checkout bags are banned federally, regardless of which sort of plastic they are made of. It sounds ridiculous, but that's what the law appears to say.
