Switch off your lights for one hour to celebrate Earth Hour on Saturday, March 26, 2011 at 8:30 pm (local time).
At that time, lights will switch off around the globe and people will commit to actions that go beyond the hour.
What else will you do to make a difference? Will you be participating?
Although this may seem small, together our actions add up.
