> Most people will have been raised to understand littering is morally wrong<p>I disagree with this. If you were raised to understand that littering was morally wrong, you are likely surrounded by folks that also understand that. On the converse, I never even _thought_ about littering growing up. Just tossing something was a thing I did. There wasn't a follow up thought at all. Not good, not bad, not "oh well someone will take care of it", literally no thought. It wasn't until I got a high school job that required picking up a lot of litter did it dawn on me that if you tossed something it still existed. At that point I stopped.<p>But, even after that I would flick cigarette butts for nearly a decade. It randomly dawned on me one day, "oh, this is littering".<p>There are vast swathes of the population that weren't raised being aware of littering. Depending on the area you grew up in you can probably still recall unsanctioned dumps on random properties in ditches and creek beds being normal. I can and I'm not even middle aged.<p>With that in mind, at least in the US we have actually come a long way. Nowhere near solved yet, but _way_ different than how I grew up. It's 100% an education problem, much like smoking. Yeah, some people will still do it, but the numbers will continue to drop over time.
