So... you're saying that there's not an accumulation of plastic waste / microplastics in the environment, or that we know any impacts or benign or negligible?
Good news if true, would like to know what position there's the most credible evidence for.
> and "landfills = bad".
I'm a fan of consumer goods, so naturally it's convenient for me if landfills == good, but I also tend to wonder (a) exactly how effectively they isolate waste issues from, say, groundwater or other environmental circulation and (b) if there might be some volume threshold past which landfills aren't an adequate solution for addressing waste streams.
We are only now starting to measure up the microplastics impact and their origin. Switching to reusable cups is a drop in the ocean, when tons of the stuff is released by simply washing clothes or makeup off your face.
> wont be solved while big economies decide to export their waste
Western countries do not have proper regulations if one of the possible outcome for waste is to be exported where those regulations do not exist.
