They started mandating that businesses charge for plastic bags where I live, and it made a huge difference from a culture that scarcely used reuseable bags/bins, to one that predominately uses them (at least anecdotally, I don't have stats). I sometimes think that obvious solutions seem harder than they actually are in reality.
