The World Wildlife Fund (WWF) Earth Hour has set the goal of inspiring people all over the world to switch off their lights for one hour on March 28, at 8:30pm local time, as part of a global vote. Switching off your lights is a vote for Earth, or leaving them on is a vote for global warming.
WWF is urging the world to Vote Earth and reach the target of 1 billion votes, which will be presented to world leaders at the Global Climate Change Conference in Copenhagen 2009. In December 2009 world leaders meet in Copenhagen to agree on a post-Kyoto policy for tackling climate change and 1 billion people voting with their light switch during Earth Hour will create a powerful mandate for our leaders to take strong and decisive action on climate change.
Cities as well as individuals will be participating. Washington, DC has signed on to be an official flagship city for Earth Hour 2009. Beginning at 8:30 p.m. on March 28th, the District will turn off non-essential lighting on many buildings and landmarks, including facilities owned by the local government.
