Fast-moving Wildfire Enters Yosemite, Threatens San Francisco Water, Power
If you live in a flood zone, you should expect floods. If you build in a forest prone to fire, you should expect fire.
Flooding is nature telling you that you should not build a house there. Fire, likewise. Fire is part of a forest's natural cycle. Fire suppression only makes the next one hotter and more violent.
Floods, hurricanes, tornadoes, forest fires. Mother Nature is a harsh school-mistress. As the sea-captain said, "I love going to sea, but I do not love the sea. The sea is my enemy because it is always trying to find a way to kill me."
The same goes for the deep woods.
If you recall, the last big fire in Yosemite was a boon to wildlife and to the forest's health. It's like a natural ecosystem, ya' know?
