Well that's just terrifying.
We've been living with plastics for decades. I don't see people dropping dead around me. Life expectancy around the world has been steadily growing, not the other way around. When exactly are these micro/nano plastics supposed to kill me? When I'm 90?
Nope, that's not the issue, and I'll happily take every vaccine going or even a plastic artificial heart if needs be.
It's terrifying because it doesn't break down. The calcium at least is more understandable.
I'd be surprised if blood tests don't include a microplastics section in the coming years.
