Earth Hour

Earth Hour is at 7:30 31 March,2007. In Sydney, people turn off the lights one hour from 7:30 to 8:30. In order to support global warm, we wish to reduce greenhouse emissions. Every one can take part on it, it's free, you just have an action-- turning off the lights, unpluging any appliances on 31 March from 7:30 to 8:30. I remember there were many countries that did it last year, like Pairs, Italy and so on. I think we should focus on our environment, because there is a only planet in which we are living. Everyone has the responsibility to do it, the government also pay attetion to this movement. It's a very simple action---just turn off the lights for one hour. That's all. It's my opinion.
