Let folks go into the forest and clear the dead wood and brush. While most fires today are started by humans, they do naturally occur. It is part of mother earths cycle, whether we like it or not.
A healthy forest does not burn as well as a forest with lots of aging dead wood on the ground. Also, clearing part of the densest and oldest part of forest creates large fire lanes while providing logging opportunities for those evil capitalists.
We as humans actually can control these thing with a little planning in a win win manner. Our biggest problem is that our government and the environmentalists will not allow us to go in and help protect those treasured forests by thinning them out and cleaning them up.
Mother nature has her own way of cleaning up old growth forests. SHE BURNS THEM DOWN TO MAKE ROOM FOR NEW GROWTH WHILE SIMULTANEIOUSLY PROVIDING NUTRIENTS TO THE NEXT GENERATION FOREST. We actually have the ability to controls some of this (not all).
Apparently, you are unfamiliar with Southern California's flora. It is a semi-arid desert. The vast majority of these wildfires are not in forest at all but in chapparal and sagebrush, often on inaccessible mountainsides.
