I will be part of this campaign tomorrow! It won't hurt turning our lights off and plugging out our appliances for an hour. This will actually help our planet save energy for at least an hour. :)
I can't elaborate more how much this campaign will help but, please let us support earth hour too!
Anyways, have you joined my giveaway contest already? You can still join by clicking on this link: http://kikaymorena.blogspot.com/2011/03/contest-survey.html
Will pick my first winner on April 1! :)
