Went to Iceland a few years ago and the biggest thing I noticed was how clean everything was. In the US, at least where I am, trash is literally part of the street. Little black “gum” streaks, random paper flying about…
I don’t remember ever seeing any litter of any kind anywhere we went on the island.
I do remember seeing a random piece of raw meat on a meadow but that was it and I’m not sure I’d call that litter.
If you’re from the west coast of the US that seems to be a more West Coast thing. I recently went to Chicago and was amazed at how clean it was. The Lyft driver told me it was the cleanest city in the country (and possibly the world since he grew up outside of the states) but I wasn’t prepared for it. I walked everywhere in the city and there just wasn’t a single piece of trash anywhere. We actively looked too.
