You might have seen some news about this event on the Web somewhere. If you haven’t, Earth Hour is a worldwide event that has a pretty simple mission: The folks behind Earth Hour want everyone to turn off to  their lights for one hour in support of climate change. If you want to participate, all you have to do is turn off your lights on Saturday, March 27th at 8:30 p.m. local time. More info about the Earth Hour initiative can be found here.
