I believe plastic may be human civilizations "Great Filter" - I'm only half-joking. In less than a century, we managed to put plastic everywhere on the planet, and microplastics everywhere inside our food sources and our bodies, including in placenta(!). Our reach exceeds our grasp, we do not yet know what dangers microplastics pose, and we do not have the technology to remediate it. Our reach exceeds our grasp. I do hope plastics end up more or less benign, but there is a very real possibility that humanities gravestone will read "Here lies human beings. They managed to make their way into low orbit and their only moon, but were felled by their discovery of synthetic polymers"
