a little midnight snack

I started wondering a few years ago about the changing of the seasons. I know scientifically why the seasons change but I have often thought that maybe it was the collective concentrated thoughts of so many people focusing on one thing that made spring/summer/winter/fall arrive. Whether consciously or subconsciously everyone thinks about said approaching season. Imagine if we could put all that thought power towards other things in this world. What else could we change?
