Earth Hour
Earth Hour started in Australia with millions of homes and businesses turning their lights off for one hour. Now it has grown to become one of the world’s biggest climate change initiatives(气候变化倡议). People are all joining together in a global effort(努力)to show that it’s possible to take action on global warming(全球变暖).
Earth Hour has brought about some new changes to our lives. People join activities such as candle-lit dinners and star-gazing parties as a response ()to the call for “going dark”. Earth Hour is a message of hope and a message of action.
Everyone can make a difference.
