Earth Hour 2012 to be observed today

Earth Hour 2012 set for 8:30 today

Many people from all over the world will be switching their lights off for an hour tonight, starting at 8:30 p.m, as part of the annual Earth Hour.

This year, Earth Hour’s I Will If You Will concept invites individuals and organizations to challenge others to an ongoing environmental commitment beyond the hour.

Started as a single-city (Sydney, Australia) initiative in 2007, the global event organized by the World Wildlife Fund (WWF) is being held annually to raise awareness towards the need to take action on climate change.

In 2011, Earth Hour created history as the world's largest ever voluntary action with people, businesses and governments in 135 countries across every continent coming together
