> Plastic food containers aren't even close to being the largest source of microplastics.

Can you give me some citations? I know that microwaving plastic containers is about the worst thing you can do with regards to microplastics, because it releases tons of them right into your food:

Both that headline and article are cringeworthy. You can’t extrapolate a bunch of flawed experiments like that to anything real.

This is a hot area of research but that means it’s a hotbed of flawed and sensationalist research. Dunking embryonic cells in a bath of ridiculous concentrations of nanoplastic chemicals and watching them die is cute and a tired, stupid trick. If you put any of your cells in your favorite drinking water they’re going to lyse. It doesn’t prove shit.
