Earlier quoted context omitted.
On the other hand, packaging (and thus plastic waste) in Japan is next-level ridiculous. A fancier food present will be often wrapped in at least 3 layers, and I've counted u to 5: bag, present paper, normal box, group package, individual package.
On the other foot, Japan is next-level clean and don't think I've ever seen trash there on the streets, especially not like in South America. So more plastic in packaging but more goes into bins, wonder if it equalizes out on harm-done compared to Japan?
in japan, most trash is incinerated... ive never looked into it, but i suspect that some amount of that turns into fine-grained soot (e.g not very healthy)
