What is "Earth Hour"?

"Earth Hour" is an initiative proposed by the WWF (World Wildlife Fund) in response to global climate change. It hopes that individuals, communities, businesses, and governments will turn off their lights for an hour at a specific time to show their support for action against climate change.

On Saturday, March 28, 2009, from 8:30 PM to 9:30 PM, let's all turn off our lights for one hour together!
