A couple of months ago there were a bunch of news stories, about how maybe oil companies should be sued, just like tobacco companies were.
Then, suddenly out of nowhere, it's actually the gloves that is the problem. It's an excellent counter to such a movement. The scientists are wrong, you see. Microplastics? Overblown!
The average joe will read only the headline/clickbait, and forever doubt microplastics.
Also, alcohol has existed since forever and humans have been drinking it since the beginning of civilization. We have a pretty good idea of what it does and how to keep it under control. Microplastics are a recent thing, it may be a dud, but it may be a serious problem for future generations, so keeping an eye on them is a good thing.
I just wrote the argument to get all the necessary research funded.

The "compared to drinking alcohol" bit feels like bait and I won't engage. They are two completely different risk factors. For one, alcohol doesn't concentrate in brain tissue.
If I remember correctly, the method they used to detect microplastics, which involves pyrolysis, gives much the same result for lipids (which brain tissue has a lot of) as pure hydrocarbon plastics like PE and PP, because they all feature relatively long hydrocarbon chains and the pyrolysis products will contain the same short-chain hydrocarbons.
I find it concerning that there seems to be such a concerted effort to downplay the significance of that finding
There is nothing to be concerned about. This is just the (re)discovery of basic chemistry and the natural response to misguided alarmism.
I may have taken the bait from the plastics industry on this one, I really don't know, but wasn't one of the pushbacks something along the lines of "well yes, there are microplastics, and yes, they do accumulate in the body, but you shouldn't worry about it - there isn't really any evidence of systemic harm being caused by them"?
Do you know if there are studies that do show evidence of harm from microplastic accumulation? It sounds really bad at face value, but I still want good, hard evidence before I'm ready to add an industry to my personal list of perpetrators of crimes against humanity.

Early research links them to serious risks, including increased risks of heart attacks, stroke, and mortality, alongside potential inflammation, metabolic disruption, and reproductive harm.
