why are plastics so much worse than other non biodegradable things like concrete or rock?

Question

I understand that plastics are bad for the environment but why are they so much worse then any other rocks and sand that are always present. If plastics can’t biodegrade why can’t they be considered as a somthing like sand after a certain point.

An addition: plastics don’t just drop to the bottom of the ocean or water. Plastic, either whole or in particles, tend to float around, and is easily stirred up by currents under water. This adds to the interactions with living things.
