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?
