Wow, you just turned "COULD be a factor" into "The plastic industry IS hurting public health." Do you see how misinformation gets started?
Do you think these plastics have not been vetted by the FDA and EPA?
You would be incorrect. I have no affiliation or loyalty to the plastics industry--in fact I think they are more harmful to the environment than most anything in human possession. Humans are PIGS. There are massive rafts of plastics floating in the oceans and microplastics can be found in every living organism, but I fail to see any benefit to promoting disingenuous woulda, coulda, shoulda narratives when discussing issues that can be studied to the point of FACTS, not just "well maaaaaaybe so, maaaaybe not"
