Today millions of people around the world will shutting off their lights for an hour starting to make a statement for the environment. It’s called Earth Hour and it has shown tremendous support since its creation in Sydney in 2007. Starting with only 2.2 million houses participating, it jumped to 50 million supporters in 2008 and this year organizers are hoping to hit their goal of one billion participants. Iconic buildings and structures are participating this year, including the Golden Gate Bridge, the Sydney Opera House and the Coliseum. So, if you feel strongly about the environment and the battle against global warming, shut off your lights tonight at 8:30 p.m.
