Break out the candles and flashlights or just enjoy the darkness because this Saturday, March 26, 2011 at 8:30 p.m. lights are switching off worldwide. Take part in a global movement to make a stand against climate change by doing one small step: Turn off your lights for one hour as a part of Earth Hour.

The Beyond the Hour challenge put forth by Earth Hour is for you to think past the hour and discuss what actions you can take to make a difference for our planet.

Started in 2007 in Sydney, Earth Hour now receives participants worldwide, including landmarks such as the Golden Gate Bridge in San Francisco and the Colosseum in Rome going dark for the cause.

We encourage you to take part and then post your comments about what you did for Earth Hour.
