I'm not making claims about a specific harmful threshold, just pointing to the rationality of concern given the ubiquity of plastic and our increasing understanding of its harm. Unless you're saying we understand the specific threshold for plastic and the risk of reaching that threshold can be reasonably extrapolated from typical levels of exposure, I think we're getting at different points.
