I blame firefighting causing forest change. Firefighting causing fuel levels to build up to unprecedented densities. Who put out fires before we started? Nobody. Nature handles that fine herself. But leave it to us to try to "improve" on it.

Fire suppression is a major problem, for sure. But it wasn't all natural in the past, either. Humans have been managing forests through the use of fire for a very long time, setting fires to thin out the understory and make areas more appealing to wildlife they could then hunt, etc., which would in turn make the forest healthier and less prone to megafires.
