I have a bad feeling about the direction this thread is going, but here goes:
The world’s population is around the general area of six billion. I am no environmental expert, but less than .5% of that turning off their lights for one hour is not going to do much of anything to help the planet. The entire project comes off as silly.
I think many environmentalists have a noble goal, but if they want to get John Q. Public on their side, they have to try a lot harder than this.
