The source I quoted about "25 rangers" and "5.5 million square miles" is wrong by the article's own words, which I too hastily scanned. 12 law enforcement rangers and 922,650 cares is still less protected than much smaller neighborhoods in major examples of "civilization." 
My point is that we should treat Mother Nature like a pretty woman with Teret's. Tread carefully but always be ready to be attacked for no apparent reason. She may be lovely, and her embrace may thrill and comfort, but she doesn't love anyone, not even herself. Best to just admire her from a distance. Getting close to her can be pleasurable but always be prepared to flee if you value your life. 
We are all just a heartbeat away from her wrath. This mom plays no favorites, except for the alert. Then again, we can die when a medical emergency causes a driver to swerve into our lane, and we'll more likely die driving to the park than hiking in it. Would we prefer to die pinned in our car, or under a falling tree limb?
