Earth Hour is World Wildlife Fund's global initative where individuals, schools, organizations, businesses and governments turn off their lights for one hour to cast a vote in favor of action on climate change.  Earth Hour will take place on Saturday, March 23, 2013 at 8:30 p.m. until 9:30 p.m. (local time).  Residents are encouraged to turn off non-essential lighting in their homes during this hour.  For more information, please visit www.myearthhour.org or http://worldwildlife.org/earthhour.
