Is it important?

Well, everybody is talking about earth hour. Do u guys no the real meaning of it? Some of my frens said it is not important and she would not follow these fools to do that. The last word she said was `why should we switch off the lights?' I am sure some of the people still thinks that is stupid to off their lights on sat 28/3/09, 8.30-9.30, but for me if something that can help the earth i try my best to help. I think everybody deserves to take a good rest of course this our planet earth need to take a nap ... mean take a good rest, so we human need to give a break to the planet earth because the earth help us a lot,.. So i hope everyone especially my frens and whoever out there plzz do something about it. If i can why cant you..
