Ditto. The entire issue with microplastics is that at certain scale they might have all sorts of bio-active aspects, like BPA and _other_ chemicals used in plastic.

I wish we did more to honor "Unknown unknowns" and make changes more gradually, especially when the difference is barely consequential. Plastic is essential for many things, but not for shopping bags, drink bottles, etc. We over-use it like crazy, and at this point if we find out that omnipresent plastic pollution causes issues, we better hope we find a solution quickly because we won't be able to get rid of the plastic.
