I think we can find and should seek out easy wins. That is we should identify the major sources of microplastics and eliminate them. From my personal observation it seems the major issue could be textiles made from plastic. Clothes and carpets made from polyester, nylon, I would guess these are subject to a lot of wear and tear and rubbing which produces plastic dust that may be breathed.

The clothes dryer is a major culprit, as it turns fabric into lint especially when the fabric is mostly dry. The appropriate care for plastic clothing is to at least end the drying on a clothes horse or clothesline. The horse is a great way to get cotton relatively wrinkle free and not turn your favorite shirts into dryer lint. But it's a bit more labor-intensive to set up that drying, so it's unlikely to catch on.
