A Brief Introduction to Earth Hour English

In 2007, WWF Australia encouraged Sydney citizens to express their support for climate change action in the first "Earth Hour" event. It shows that everyone, from children to CEOs and politicians, has the ability to change the world they live in. In Sydney, Australia, 2.2 million people and more than 2,000 enterprises turned off their lights for an hour to show their opposition to climate change.

In 2008, it is planned to extend Earth Hour to other parts of Australia. But then Toronto, Canada signed up for the event, and soon 35 countries and nearly 400 towns participated in the event. It tells the world something convincing: the climate challenge facing our planet is so great that it needs global change.

With the invitation to "turn off" extended to everyone, Earth Hour quickly became an annual global event. It is scheduled to coincide closely with vernal equinox on the last Saturday of March every year to ensure that most cities are in darkness when it goes around the earth.

In 20 1 1 year, Earth Hour witnessed hundreds of millions of people in 135 countries without power for one hour. But it also marks the beginning of something new-beyond the time when we promised to take lasting action on climate change. With the help of the power of social network behind the message of "Earth Hour", we hope to attract more people to participate, so that we can build a truly global community and commit ourselves to creating a more sustainable planet.
