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.

Concrete is not that much better. Excavating sand from river bed or sea floor causes erosion, water pollution and devastates organisms that are dependent on it.
Depends on the sources of other ingredients, crystalline silica and naturally radioactive materials could contaminate the concrete and that’s a major air quality concern.
And that’s not counting the giant amount of CO2 footprint the concrete industry has. For one curing of concrete release CO2, production and transportation of concrete also consume lots of fuel.
Less much of a problem for already developed country, but for developing countries that are going through a construction boom these effects could be detrimental.
