That is a philosophical question about the intrinsic properties of plastic versus reusable bags.  It also involves consequentialist questions about the effect of these bags on the environment, energy use, and pollution.

That’s a really tricky question!  I think it’s better to say “compostable bags” or “biodegradable bags” instead of plastic bags.
