I'm confident that microfiber cloths are responsible for 0% (rounded to the nearest whole percentage) of oceanic microplastics. But it's possible that all clothing and fabrics combined are responsible for a significant fraction of microplastic pollution. If this is the case, then the government should do its duty in regulating externalities and mandate exhaust filters in washing machines.
