What is Earth Hour?

The world's largest conservation organization, World Wildlife Fund (WWF), started Earth Hour in 2007. Initiated in Sydney, the hour honoring the planet has become a big event on all seven continents. From the tallest building in Dubai, to the most romantic spot in Paris, many of the world's most popular landmarks participate.
