Earth Hour --appeal

Earth Hour is a global event organized by WWF (World Wide Fund for Nature, also known as World Wildlife Fund) and is held on the last Saturday of March annually, asking households and businesses to turn off their non-essential lights for one hour to raise awareness towards the need to take action on climate change . Earth Hour 2012 will take place on March 31, 2012 from 8:30p.m. to 9:30p.m., at participant's local time...In February, 
Earth Hour launched its 2012 campaign, “I Will If You Will”, with the intention of engaging its growing global community to go beyond the hour. Earth hour urges community & inspires people from all corners of the globe to take sustainability actions, and to share their commitment to the environment with their own social media networks.
