Plastic bag bans have spread to over 100 countries, but I'm starting to question if they actually reduce waste or just shift the problem. In my city, the ban led to a surge in sales of thicker plastic bags that people reuse less often, and paper bags have their own environmental costs. I've seen studies on both sides, some showing decreased litter, others finding minimal impact. Can we really call a ban successful if it doesn't address the root of single-use consumption?
