Additionally, what I find particularly frightening and unsettling is the possibility that we'll never be able to know just how harmful microplastics are, due to the rapid loss of anything we could call a "control group" on the planet. Rapid industrialization and globalization has led to land, water, and sky all being infused with this stuff; are there populated areas anymore where we could point to and say "this place is untouched by microplastics" and compare the health of the people and ecosystem there to the affected areas?

Indeed. And, whatever organisms are/were most likely to die out because of exposure to microplastics, probably already have, given this shit is everywhere now. Sobering thought!
