Those are all great reasons. What's the need to push for yet-to-be-subtantiated fears of microplastics?

What is OP fighting for? Idk, an unbiased view of reality, maybe?

My point is that limiting plastic use (especially single-use plastic) is a win in my book even if it is ultimately done for the wrong reason. Thus it's not worth my time going out of my way to disprove specific research that still ultimately points out the need to curtail plastic use...
