Earth Hour 2013

It is easy to forget how much we depend on the planet for so many things like food, fuel, water and fresh air and that the actions we take—from the energy we use to the food we buy—have an effect on the world. Earth Hour is our chance to make and show our commitment to protect our planet not just for one hour a year, but every day.


Earth Hour takes place on Saturday, March 23th at 8:30 pm local time. At that moment, hundreds of millions of people around the world and some 4,000 cities in 87 countries will turn off their lights for sixty minutes in an international call to stop global warming.


Participation is easy, and we're urging all our friends to join us. All we need to do is turn out our lights for a single hour. The blackness that follows will send a message to Washington and other capitals that it's time to take strong action and make sure that the Earth remains habitable. But we all need to participate for that message to be heard. So gather your loved ones and light some candles, then tell stories, sing songs, and dream of a sustainable world. We can build it if we try.


Talk to your friends and neighbors and urge them to shut off their lights, too. Let's join people from New York City to Shanghai to spark this movement to save the environment. Because this is the hour when we can all make a difference by coming together in a single, simple act. This is the hour when we dissolve all borders to bring lasting change to the world. So let's hit the switch and get that party started!
