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?

First of all, plastic will, as everything, be eroded by wind and other elements, and will release particles with time, no matter what it’s made off. Glass is more long lasting than plastic and still gets eroded by nature.
If you eat stone you shit stone. If you don’t shit it it gets dissolved in your body, captured by blood, brought to kidneys, and you will pee it out later on.
If you eat plastic some will get in your blood and it goes around grinding on your heart valves or clogging veins in your brain. No way your body can filter it out.
Animals, humans included, have many ways to get rid of harmful thing that existed when the evolution happened. We have zero protection vs plastic.
