I think a lot misunderstand microplastics too. Some people fear Teflon. Teflon isn't a problem and is truly harmless... it's the byproducts and components of manufacturing Teflon that are a problem. Not that anyone's talking about that in this thread, but it is something I've seen related to microplastics that comes up.
I make it no secret that I am a philosophical pessimist. But there's enough suffering in life just at base-level, and while microplastics are a problem and something should be done about it, the number of people cowering over every minutia of everything and being afraid of living life is getting annoying as all hell.
They're so afraid everything is going to kill them, but what good is having a long and healthy life if you don't actually live it because you're too busy crying online about things you can't change or avoid and trying to proselytize others into crippling fear, rather than writing letters or donating to the people that could actually could make things you're afraid of be better?
Too many people are worried about too many things but refuse to take any action on those things... even the action of just being informed. So often they latch on to a fear without even understanding the thing they're afraid of or why they should be afraid of it or the appropriate fear level and are more concerned with being concerned than with the thing itself.
