Why is plastic that doesn’t break down a problem? Plenty of rocks don’t break down either?

I’m not talking about plastic with specific issues (i.e. plastics bags look like jellyfish to sea turtles so sea turtles eat them and die).

But the sand on the beach is still going to be sand on the beach in 10,000 years, so what specific issues are going to happen from X amount of sand grains being plastic?

Edit: Based on the first few replies: I’m talking about plastics that are said to still be there, unchanged, millions of years later. Like they’d show up on the geological record. “Forever plastics”

IF they don’t decay what’s the issue? Or is them not decaying and “forever plastics” a misconception?

Bioaccumulation. Plastic breaks down into microplastics. A little fish eats a microscopic piece of plastic. A larger fish eats 20 of those smaller fish and now has 20 little pieces of plastic. An even larger fish then eats 20 of those fish and now has 400 pieces of plastic. Then Bob eats one of those larger fish once a month. After a year Bob has eaten 4,800 pieces of plastic. This isn’t very good or Bob or any of the other organisms that are full of microplastics.
