Indeed.
Hell, just unchecked fires alone - archeology indicates that before the western half of the United States was settled (even before the pilgrims settled the eastern half) pretty much everything that could burn west of Texas was always on fire, or recovering from an earlier fire. Tons & tons of CO2 released into the atmosphere every year had to do something, right ?? Right ? Primitives ? Bueller ?
Since settlement, wildfire frequency & spread has reduced. Up here in the northeast, we haven't had a major wildfire event in over a century.
