Earth Hour countdown

Want to participate in a global phenomenon and work together for a future with cleaner air? In three days and 4 hours, at 8:30 p.m. local time on March 27 we encourage you to participate in Earth Hour 2010.
Call for action on Climate Change by turning off your lights for one hour.
The Empire State Building and 54 states and territories will do it this year.
Earth Hour began in Sydney, Australia, and during the past three years the World Wildlife Federation has taken this idea to a global level.
