I haven’t seen studies so this is just conjecture, but I believe its the same material. Likely it does, but not close to the same magnitude of car tires.

I’d argue it was destroyed, in the last 2 seasons.

Plastic, PFAS, CO2 Pollution, Tire dust (leading problem is cause of Asthma), Leaded fueled small prop planes (still standard), Oil, Industrialized agriculture (destroys nutrients in soils so food does not have it, produces tons CO2), many more.
