Let's talk about the pine beetle in the sense of natural forest fires. The indigenous people used to burn the mountains down on a regular basis to get lodgepole pines for teepees. They discovered in Yellowstone, after “Let's protect the forest, let's protect the forest, and no fires”, that all of a sudden they had one of the most devastating forest fires the U.S. has ever seen because they didn't burn the underbrush. We're building a firetrap in the forests if we keep all fires from happening.
