"Plastic is bad" is the current fad. There is nothing clear about it. Sure Macroplastic causes well documented damage. I don't know of any proven effects of Microplastics in large animals/humans. The argument seems to be more "it can't be good". I'm not at all invested in plastic and I'm all for protecting our environment, but I sense some sort of mass hysteria going on here again. Good that people are documenting the spread of man-made stuff and look for negative effects, no need for the permanent fearmongering. Also plastics are very different, some are rather bad (pvc,epoxy) others quite harmless (pe,pp).
