Earth Hour started at 7:30 p.m.on March 31, 2007 in Sydney.More than 2.2 million homes and businesses turned off their lights for an hour.
　　A year later, March 29, Earth Hour 2008 became a global activity.50 million people in 35 countries took part in it.
　　On March 28, 2009, more than 2, 100 cities in 88 countries joined in it.And the idea "Earth Hour" came to China.
　　On the evening of 8: 30-9: 30 of March 27, 2010, we turned off lights together with people all over the world in order to fight against climate (气候) changing warm for this year's "Earth Hour' activities.
　　Global warming is causing the ice to melt on mountains all over the world, then the sea level is rising and fresh water is disappearing with the disappearing ice.
　　It is very important for us to take part in this action.Nowadays the environment problems are becoming more and more serious.Humans just want to take more and more from the earth and never make a contribution (贡献) to the earth.The relationship between humans and the earth is just like that between children and mother.So do something as much as you can, the earth will be better than now. We should pay more attention to the problem of climate change and the climate change is one of the most serious problems in the world.I hope everyone takes action and joins in the activity of "Earth Hour".
