In 2007, the citizens of Sydney, Australia took a stand against climate change and turned off their lights for one hour as a symbolic gesture of their support of climate change mitigation. The symbolic gesture had a notable bi-product--the hour without lights was equivalent to taking 48,000 cars off the road. Earth Hour was born.
Earth Hour happens again this year--tomorrow night. The movement has gone global and includes cities such as: Toronto, Chicago, Phoenix, and San Francisco are involved.
