Initiated in Australia in 2007, Earth Hour is a time zone-by-time zone plan in which people around the world are encouraged to switch off  their lights for 60 minutes on the last Saturday night of March to show their concern about global warming and climate change.The campaign aimed to send out more and clearer messages to world leaders before they meet in Copenhagen in December to have a new global impact on curbing emissions of greenhouse gases. The UN Climate Panel says greenhouse gas emissions are warming the planet and will lead to more floods, droughts, heatwaves, rising sea levels and animal and plant extinctions. World emissions have risen by about 70 percent since the 1970s.

In Shanghai, China's financial hub, floodlights to illuminate some 160 buildings , including the world's third tallest TV tower "Oriental Pearl" and the 492-meter-tall World Financial Center, also went down. Skyscrapers with glowing windows dominating the night skyline are usually considered symbols of modernization in China. But Saturday night, going dark became trendy.

     In many Shanghai outlets of international fast food chain KFC, people enjoyed candle-lit dinners after the restaurants dimmed lights.

     As everybody can see, this will send an important message to the world that people in China are becoming more aware of climate change issues. It's a very special night because it sends an environmental message to us,too. We hope such an activity will inspire everyone to make energy saving a daily habit.

   But in spite of this, not everyone is so convinced and agreeable. Some consider it a show for the moment. But I strongly support this kind of activity which may arouse people's concern about the environment by using less power .It is true that Earth Hour is just for one hour each year. One person may be small, but we can make difference if we work collectively to change our own behaviors.

    Anyway,  the action showed millions of people want governments to work out a strong new U.N. deal to fight global warming , even though the global economic crisis has raised worries about the costs. We have been dreaming of a new climate deal for a long time. Now we're no longer so alone with our dream. We're sharing it with all these people switching off  their lights.
