Once upon a time this question was asked in grocery stores. Sure isn’t any more, not where I live. I don’t know if I could even choose paper if I wanted to. Anyway, it turns out the environmental issues aren’t as clearcut as we’ve been led to believe.
Plastic lasts forever in the landfill, but oh the chemicals used in making paper! The new bioplastics aren’t strong enough to hold groceries, though they do decompose. So is the answer canvas? Seems obvious, but the folks at The Rooftop Blog carefully look at all sides of the issue. It’s not quite hands down…you’ll want to read this.
I know one thing’s for sure: I often forget to toss my canvas bags back into the car after unloading the groceries. That’s no help!
