Earth hour

I wanted to search for some material and opened google.ca. Interesting, the page is changed, a line in the page caught my attention : We've turned the lights out. Now it's your turn.

It is a google's effort to raise awareness for energy conservation effort. On Saturday, March 29, 2008, Earth Hour invites people around the world to turn off their lights for one hour – from 8:00pm to 9:00pm in their local time zone.

I felt that this is one effort where an individual can contribute and see the result.....
