“Lightning starts most fires”
Possibly but a large percentage are caused by arsonists. Would guess at least 50%.
“Would guess at least 50%.”
I used to serve on a fire board in the mountains of Colorado. Near cities arson is more prevalent. Out in the sticks (where most fires happen) it’s lightning, then campfire stupidity, and then the rare arson. Arson is mostly a population density thing. Here’s the net’s answer:
21 percent
Rice reports that debris burning starts the most human-caused fires, at 29 percent, with arson the cause of 21 percent of fires. Equipment use causes 11 percent of fires, while campfires and children playing with fireworks or matches each cause 5 percent of fires.
