I have yet to read any fully documented health related issues. But how can there not be any health issues ? For example, I saw here on HN that micro-plastics were found in Human's brains. Also we have see a rise in Dementia and Alzheimers over the past decades. Again a bit of a coincidence to me, but makes you wonder. Personally I think plastics is not the only cause, but I think it is one more thing to tack on to the environmental damage we have cased over the decades. And that damage is now getting to the point that have real health consequences, especially to the young.
