Here's the thing. Even if this isn't bad (which I would argue having to resort to asking armed criminals to police your streets certainly isn't good), that doesn't make it "upliftingnews."
It has the same vibe as a "Trump gets cancer" headline. Would a lot of people be super happy about that? Sure. But it's not "upliftingnews."
I'd be really interested to see a quantitative analysis of how much difference it would make if all 330mil of us swapped to renewable bags.
My gut is that paper bags are pretty clean overall, and that grocery bags are a tiny fraction of paper usage in the US. But I'd be really interested to be proven wrong.
