This year's Earth Hour event is just 10 days away. On March 31 at 8:30 p.m. local time, people will turn off their lights to bring attention to the need for addressing global warming.
Since it began in 2007, Earth Hour has become a worldwide event, so by turning your lights off at 8:30, you'll be joining millions of people around the planet. Also, if you can, think of ways to go "beyond the hour." For instance, I am planning to keep my computer off and unplugged for the entire day.
