I can’t throw away plastic supermarket bags. My reluctance is because they are such a waste of difficult-to-degrade plastic if their only purpose is to sack up food for conveyance from a store. I believe deep down that if you are going to sack your food in plastic that once you get it home, those bags ought to have a second or third life in the home, a kind of active recycling. In my household plastic shopping bags are used to hold bottle and can recycling, used to contain too-old leftovers so they can be thrown in the garbage without their degradation becoming noticeable, and finally being handy receptacles for cat exhaust. If the bags just go right into the garbage from the market then their 10 minutes of use and 3000 year lingering feels like a horrible sin. If you can get them to do a host of other things, then I believe you should. People look at me oddly when I tell them to save the bags, some people just immediately throw them away, but I hope by answering this Plinky prompt, they understand why that isn’t right.
