Japan is a beautiful country with incredibly clean major cities, but it has a severe lack of public garbage cans, making it difficult to throw away trash when you’re out and about.
The United States is a much dirtier country, with trash strewn about the streets of major cities, yet public garbage cans are everywhere and usually easy to find when you need one.
Hmm… so I guess more garbage cans paradoxically leads to increased litter? At least, that’s my clueless, single-variable analysis of this subject that ignores all other factors.
