Isn’t the majority of this buried in the ground in dumps that are sealed off from groundwater?
I suspect our clothes, cars/tires, houses, and other things that live outside contribute more to microplastics than food containers.

The question should be reversed, is there anything made of plastic that doesn't shed particles? It seems likely not, they all tend to shed.
In the other hand, I probably have about a pound of Tupperware in my body. I guess my point is that you’re right about micro plastics in the environment, but I’m more concerned about the ones in me.
(Strenuously agree that both are bad).
(Still not buying any Tupperware, though).
