Nature is not to be Changed except by G-d to promote Fear of G-d

 Rashi (Koheles (03:14) The Creation is fit to be eternal, and it cannot be changed, either by adding or by subtracting, and when it is changed, it is because God commanded and caused it to be changed, in order that they should fear Him. The ocean broke through its boundary in the generation of Enosh and inundated a third of the world, and God did this so that they would fear Him. Seven days, the course of the sun was changed in the generation of the flood, to rise in the west and set in the east, in order that they fear Him. Also, the sun went back ten degrees in the days of Chizkiyahu; and in the days of Achaz his father, the day was shortened and the night was lengthened on the day of his death, so that he should not be eulogized. All this was so that they would fear Him. Therefore, there is nothing better for a man to occupy himself with than with fulfilling His commandments and to fear Him.
