Actually, where do many things go? Rocks become stones, which become
pebbles, which become sand, which becomes microscopic sandy dust and
the inorganic component of soil. How does this differ from the harmful
microscopic grains of degenerated plastic - and, presumably, paint?

And biological fauna become oil and flora become coal.

All plastic degrades eventually.



And pebbles and sand can be recycled into concrete, which can
then be recycled again ...
