If all packaging was 100% biodegradable, having no more effect on the ground than, say, a fallen leaf, would littering still be stigmatized?
I’m kind of in two minds about it. On one hand, I can see a Solarpunk society having a lot of cleanliness hangups that would make it be seen as just as bad if not worse. But I also think individual people would get kind of “meh, who cares?” about where they throw their trash, if they were told there weren’t any long-term effects.
Maybe there’d be a mix of both attitudes in play, which could be written very humorously!
