@jensorensen this is the very thing that has baffled me about these groups. They're obsessed with stuff in the air, or microplastics, but also often support groups who have very clearly loosened regulations allowing more microplastics in food.

I know the answer is that education is underfunded, and they just haven't learned critical thinking, but I don't like that answer. All their talk about research, it's very unsatisfying how little it actually matters to them.
