fwiw, i don't actually think that a plastic bag ought to fall in the definition of "single use plastic". you can actually recycle them at walmart. i only take small numbers of them for items that need to be protected from leakage in my school bag (like strawberries, which otherwise get messy), but what i do is hang on to them and use them as garbage bags, after i've used them repeatedly for other reasons, in some cases.

it would be useful if they were biodegradable in the end, so that they decompose in the landfill. but, it's not the same thing as straws or forks; these are not meant to be used once, and, for most people, are probably used repeatedly. there is a future for plastic bags, even when so much of this other stuff is converted or done away with.

a bigger problem than any of this is lids, and that goes for a large number of items. plastic lids are not usually recyclable. to be clear: they are in theory recyclable, but almost nobody recycles them. for years, i ignored this and sent them through the blue bin as a means of protest, hoping that if i overloaded the system then they would increase their ability. nowadays, i separate them out and hand them over to whole foods, instead. this is something that both my city and your city and all of the other cities should be dealing with, and that some agitation is required around - we should be pushing mass protests to increase our local capacities to deal with plastic, as a big part of the problem is that the recycling facilities are inadequate. they can't process things they should be able to process, so they throw it away, instead.
