Do you know what this picture represents? It stands for Earth Hour. Right now, you're probably thinking what is Earth Hour? Well, it's an hour that you turn off your lights on March 28th from 8:30pm to 9:30pm.
Earth Hour all started in Sydney, Australia when 2.2 million homes and buissnesses turned off their lights. This went global. The whole world started to know about this and then other countries and cities followed.
In my opinion, I think that this is a great idea. I mean just think of it- one hour without electricity, anyone can do it. Some people think it doesn't mean anything but it does, so participate along with millions of people and turn off your lights on March 28th,2009 from 8:30pm to 9:30pm.
