Earlier quoted context omitted.
When I go fishing at the creek it is not a ton of paper bags littering it. Single-use plastic bags are terrible and people overly use them. Go get a pack of gum from a bodega and you'll be offered a plastic bag by default. Maybe we shouldn't necessarily ban them, but we should definitely tax them to make people question "do I really need that bag?"
it sounds like your assessment of environmental harms is mostly guided by surface appearances, but things like paper mill pollution are not easily visible or understandable
Either way, we can also have regulations protecting against paper mill pollution. It's not like we have to have one or the other. We can do both!
But in the end my argument is we should do much to eliminate the wastefulness of single-use bags in general. Not that we should substitute one for another. Quit throwing so much shit away every day of your life is my argument.
I fully acknowledge there's absolutely useful places for disposable things. Medical equipment, certain kinds of packaging, etc makes a lot of sense; there's often not really any good alternatives. But being given a throw away bag after buying a pack of gum is a simple example of the egregiousness of our throw away culture.
Go kayaking on most rivers in the US and get absolutely inundated with single use plastic trash of the worst kinds and continue telling me how bad doing anything is. Fuck single use plastic shopping bags, I can't wait to see them disappear.
