Earth Hour began in 2007 in Sydney Australia, with 2 million people turned  their lights off for one hour to take a stand against climate change. A year later, the number has grown to  50 million people participating. The most famous cities in the world turned  the lights of its monuments off: in Rome, the Colosseum,  in San Francisco, the Golden Gate,  in Sydney the Harbor Bridge.
In 2011  Rio de Janeiro switched the lights off of Christ the Redeemer and had the picture was published in the famous British newspaper The Guardian.
And you, what did you do on Saturday between 20:30 and 21:30?

It is ok if you have switched the lights off, but in 2011 we should go beyond the hour. So after the lights go back on, think about what else you can do to make a difference!
