Last year Sydney, Australia tried to think of a way to get the entire city to do something about climate change problems. Their idea was to shut all the lights off in the city for 1 hour - Earth Hour.
Earth Hour: March 29, 8 - 9 PM
As an initiative of the WWF, Earth Hour has grown from a single event into a global movement. 26 major cities and hundreds of councils and towns from more than 35 countries are on the final list of participants. Many iconic buildings and landmarks around the world will be turning out their lights for Earth Hour including the CN Tower, Toronto; Golden Gate Bridge, San Francisco; Sydney Opera House, Sydney; Brighton Pier, UK and the Sears Tower, Chicago.
Candlelight dinners, unplugged concerts, glow-in-the-dark sports, community star watching.. those are just some of the ways people are marking the hour. You can participate even if your local government is not on board. Simply shut all of your lights off between 8 and 9 pm local time.
Each one of us, working together, can make a positive impact on climate change - no matter who we are or where we live.
