Right, not today. But large quantities of wood did not decay in the Carboniferous Era, trees didn’t rot and piled up and eventually became coal.The carbon doesn't just build up in the earth.
”Based on a genetic analysis of mushroom fungi, it was proposed that large quantities of wood were buried during this period because animals and decomposing bacteria and fungi had not yet evolved enzymes that could effectively digest the resistant phenolic lignin polymers and waxy suberin polymers. They suggest that fungi that could break those substances down effectively only became dominant towards the end of the period, making subsequent coal formation much rarer.”
