I know it’s a bit late to post an entry of this event but I stumbled upon this site a few minutes ago and find it interesting to share. Earth Hour 2010 has been held more than a week ago around the world. It is an annual worldwide event to show support for action on climate change. So did you turn your lights off? Check out these interesting Earth Hour 2010 pictures (from Boston.com) that features popular places around the world. As you click on each pictures, you can see how they look like before and during the Earth Hour.
