1 hour agoI don’t know. I haven’t seen the research.
I was alarmed by it at first but it’s been a few years now and the parks where I go which used to have them don’t seem any more littered fwiw. If anything less so.
But that’s anecdotal and as I understand it the decision was made based on more than that.
Idk, it looks like it works (or maybe people are just getting better at not littering and it correlates), but this is one of those things that can be measured so I’d trust department of conservation research over my own anecdotal evidence.
