"Microplastics found in X" has become a pretty weird sport.
The phenomenon is worth studying, but it's not hugely surprising given how ubiquitous they are (another thing you find in every human, probably in higher quantities, is sand). But despite tons of scrutiny, there are no studies showing that it's actually hurting us.
We've done some really sketchy things in the early days of industry (leaded gasoline, etc), and have gotten into this overdrive where we're jumping the gun on a lot of substances that are probably not bad. Every year, you have several headlines in the mold of "X is everywhere and might be killing us"... but never really followed by that "oh yeah, it was really killing us" part.
