Earth Hour 2013 - March 23 @ 8:30pm

Earth Hour 2013 happens tonight, March 23 -- 8:30pm. If you happen to be in the KLCC area, watch the lights go out at the Petronas Twin Towers and back up again one hour later. Many shoppers and employees watch this spectacle every year.

Happy Earth Hour wherever in the world you are..

Earth Hour is the single, largest, symbolic mass participation event in the world. Born out of a hope that we could mobilize people to take action on climate change, Earth Hour now inspires a global community of millions of people in 7,001 cities and towns across 152 countries and territories to switch lights off for an hour as a massive show of concern for the environment.. from the Earth Hour website.
