People already throw things on the ground because it’s somebody else’s job to pick it up. It’s a culture issue broader than simply “personal responsibility.” People in the US don’t like to be inconvenienced or we tend to shriek about personal freedoms.
In the US you likely need wildly punitive measures - not just small fines - to deal with the issue. Also would fall along party aligns with minutes and become a partisan issue immediately.
Yes well-executed public awareness programs can shift culture over several years (this campaign is over 40 years old wow!) but we also need to clean up what's there now and what will continue to accrue until that shift occurs.
I would be more than happy to see my city or state tax dollars put towards a cleanup initiative. We have a particularly fragile ecosystem
Even just seeing people cleaning up is enough to begin to change perceptions, because it turns it from an impersonal action to a personal one - "I'm throwing this wrapper on the ground" vs "I'm throwing this wrapper on the ground for old Joe to pick up."
We can all be the change we want to see, even if it's just a minor effort.
Around here major cleanups are done by some of the local "community groups" but they also have a department of parks that does some additional to named trails.
