What a silly reply. Yes, there are many studies about the consumption of hazardous chemicals, including gasoline. There are even many about just the fumes -- no need to regularly drink it.
My point: The "hair on fire" comments about nano plastic still hasn't been borne out by peer-reviewed scientific research. I recall on HN someone mentioned that a recent discover was that tyre dust is a large potion of micro plastics in our world.
I am with you on finding the studies that verify these hypotheses, but for newly discovered problems, I think there will not be any long-term impact studies, but we must make a decision today about if this is safe or not.
It doesn't make sense to me that the plastic would be beneficial. It is either neutral or detrimental and I not that no plastic is neutral.
If youre so certain about your ability to find long term studies on the consumption of micro-pieces of toilet paper or gasoline, then surely you can find one on plastic ;).
Not many have their hair on fire. People just want to make a conscious effort to avoid what common sense says to avoid.
