I remember in school we switched from single-portion paper milk cartons to square bags of milk that you punctured with a plastic straw. This was sold to us along with a muppet skit explaining how to use the milk bags (the muppets rated it "one thumb up and one thumb down, to cover the straw hole when you puncture the bag"). There was a poster in the cafeteria comparing the giant pile of milk cartons relative to the small pile of plastic pouches. We paid much more attention to what adults said than they ever gave us credit for, and they had been telling us about renewable and non-renewable resources, about recycling, about landfill space, and about externality. We knew, even if the rational outcome was the same, that it was more than big pile vs small pile.
I remember when bag fees started showing up, and at the checkout grocery stores began selling... reusable plastic bags. People seem to collect these now, maybe 30-40 per household, which is fine by me I'd rather have 40 bags in someone's pantry than 4,000 floating around outside. But it seems excessive. I've accumulated about that many: I on occasion "win a prize", family members bring items over and leave the carrying bags behind, donate money to anyone and you're sure to get a tote. I actually don't have any rope bags though I wish I did, my mother still has hers and she's not parting with them. I think the rope bags are more convenient than anything else, but then what happens to the 40 odd plastic bags I've accumulated?
