I think many people have already heard about this. Earth Hour 2008 has been held today at 8PM and I am going to participate in this. Its approximately 2 hours from now and then all the people who are participating in this will switch off their electrical equipments for one hour. so I am going to participate in this and want to contribute in saving our planet. So I wish all my blog visitors to do the same thing and contribute yourself. If you want to know more information about this then please visit http://www.earthhour.org
