So not a completely idiotic policy.
But recent terror attacks (which used knives and vehicles, not bins) prompted their removal again.
We need to teach common decency, adults need to set better examples, and the cops walking the street need to start ticketing people for littering - whether it's a fast food bag or a cigarette butt.
So, they're not the same, then? Those willing to walk a couple of steps to throw things away weren't littering before.
If something is easy, then you get into the habit of doing it without even thinking about it.
That is not the dumbest idea I have ever heard of. But it's close.
Lighter-weight solutions were later introduced that limited the ability to place large objects in bins, or substituted large bins for clear plastic bags supported on a frame. These are still reasonably prevalent, though there could definitely stand to be more of them around London.
Last time I was in Victoria Station in London, there was one alumin(i)um hoop with a clear trash bag, emptied constantly.
Perhaps that’s ok in busy central locations where a street cleaner will be along shortly to pick it up, but the problem is that people are now accustomed to dropping litter and do the same in suburbs, parks, and countryside where it just accumulates.
How do we solve it? We need to teach environmental education in schools and try to stop littering habits before they form.
But also, I think a great application for robotics technology will be litter picking, street-cleaning robots!
