I also want to refer you to some research that was done last year out of Utah State University. I think you provided a commentary for that article. I don't want to say I found it interesting, but it was interesting in one way.
One of the things the article said.... I know the research is emerging also. We talk about ocean microplastics and we talk about landfills, but there's recently been some research suggesting that there is widespread airborne microplastic pollution that could pose a risk to human health and has already polluted even the remotest corners of the earth. I think you mentioned the Arctic. They have some studies that found particles there also.
How big a cause of concern do you think this is, and how do we address it?
