In all of nature, there is no sound more pleasing than that of a hungry animal at it's feed. Unless you are the food.
Natural disaster is an oxymoron.
Nothing in nature is disastrous, only man's reaction to it is. Fires racing across hills of dry brush is nothing. But put 100 high-priced homes in their path and all of a sudden you have a disaster. The current floods in Central California are another example of man-made calamities. For eons, rain has fallen, snows have melted, and rivers have overflowed their everchanging banks.
