I've read that the majority of microplastics come from tire wear (national geographic quoted 28% of the total), and because there's no good alternative to wheel tires, it's unlikely we'll see a decrease of pollution here. So even if we found an alternative to bottles, plastic bags, clothing, etc, it still won't make a dent in pollution unless we convince the world to use a form of public transit that doesn't make use of plastic tires.
We could reduce human consumption of the particles if we only consumed lab-grown meat & hydroponically grown vegetables where the water is ultra-filtered before use.
