The Saturday, March 23, is a global event where everyone on Earth can help conserve energy, Earth Hour. It’s easy to participate, all you have to do is turn off your lights for one hour between 8:30 and 9:30 p.m. Millions of people around the world will turn their lights off in homes, office and government buildings, to celebrate Earth Hour, and have been doing so since 2007, the first year of the event.

Earth Hour got its start in Sydney, Australia, in 2007, which saw 2.2 million homes and business turn their lights off for an hour. Since then it’s become a global event with hundreds of millions of people taking part in the event.  Some of the bigger participants include San Francisco’s Golden Gate Bridge, the Cn Tower in Toronto, Rome’s Colosseum and the Sydney Harbour Bridge. Some people schedule a candle-lit dinner at that time or even a candle-lit bath. Whatever it is you want to do, you can help save the planet (a little) but turning your lights off.
