Shut Off the Lights For Earth Hour Tonight [Video]

In 2007, the city of Sydney shut off its lights to promote reduced power consumption. In 2012, people across 135 countries can join in during the World Wildlife Foundation’s annual Earth Hour event and go dark from 8:30 P.M. to 9:30 P.M. in your local time zone. For the ecologically minded, the event is an opportunity to raise awareness about power consumption, and the global community in which we live. For the astronomically minded, it could be a golden opportunity to see the sky with less light pollution. Whatever the reason, will you be dimming the lights tonight?
