I'm really starting to think that this microplastic fearmongering is really just a psyop, just like man-made climate change. Think about it. Plastic is probably one of the most stable, non-reactive man-made substances. It's no different that dust in that sense. So, it can't be poisonous. Our bodies are designed to handle things that are much more reactive.
It only scares people because people immediately think of larger fragments of plastic that can actually cut up your organs, but on a microscopic level? No. People who accidentally swallow plastic without choking are never poisoned, (unless the plastic is already contaminated with other chemicals) how is it any different than plastic on a microscopic level?
And the crazy things that people are suggesting that you should do to reduce the releasing of microplastics are no different that what people suggest to reduce your "carbon footprint". Things like giving up your car (because apparently most of the ocean bound microplastics are from tires) and washing your clothes with cold water.
@Tadano I think it only makes an impact if you consume too much of it (i.e actually drink from BPA bottles). Tiny fragments from everywhere else probably won't harm you. There are fragments of aluminum everywhere which can cause more serious health problems, but I don't see anyone talking about that.
