What if there really was a zombie apocalypse but instead of people it was tree who went after other trees and the only way to stop a zombie tree was to cut, split, stack and then season it down to less than 20% moisture content and then burned it? If you skipped any of these steps, except in the case of rounds less than about 5" in diameter, the fly ash would infect more tree. Would we still have all these green burners giving us a bad name? What other ramifications would there be?
