Personally, I think that the Microplastics Moral Panic is a textbook study of F.U.D.

There is practically nothing that ordinary people can do for prevention, mitigation, diagnosis or treatment of microplastics in our bodies, so I therefore conclude that it is futile and wasteful to worry or argue about it, unless you have abundant free time and resources to get paranoid strangers all in a frenzy, for no good reason.

I half-assed try to avoid plastic in contact with (especially very) hot food or drink, and avoid it in long-term food containers, in no small part because I've seen things like plastic cooking spoons losing non-microscopic parts of themselves in food, and I find the stains plastic storage containers acquire after a little use kinda worrisome (I'd rather my reusable storage containers not be that permeable, thank you very much), but otherwise agree that any real amount of effort to avoid microplastics would probably do more good if it took the form of a 20-minute jog per week, i.e. "don't even consider worrying about it unless you've really, really got all your other health stuff sorted out"

Like I'm pretty sure the bigger health risk with a plastic soda straw is the soda, not the straw, you know?

Did this apply to people freaking out about lead a couple decades ago?

What about those advocating for smoking bans in shared spaces?

Cholera outbreaks near the city water wells?

Or are microplastics special in some way?
