It's a serious problem, but it's one that requires people to stop using so much plastic; to make sure they re-use plastic; and to make sure that plastics are recycled after use.
Microbeads in cosmetics and microfibres from clothing are a huge problem.
So much this and I don't know that we really have an answer to fix this. This micro things are toxic to the entire aquatic ecosystem.
It isn't difficult to do. All that is needed is an incentive like making inclusion of plastic micro-beads illegal. Isn't California considering doing that?
