At 8.30pm this saturday it is global Earth Hour.
Earth Hour started in 2007 in Sydney, Australia when 2.2 million homes and businesses turned their lights off for one hour to make their stand against climate change. It is now a global event, in 2009 hundreds of millions of people took part with over 4000 cities in 88 countries officially switched off to pledge their support for the planet.
Earth Hour 2010 is this saturday at 8.30pm (local time) and is asking that people across the world stand up, take responsibility, get involved and lead the way towards a sustainable future by turning off the lights (and anything else non-essential) for 1 hour. Not only a great way to help the planet and raise awareness but also the perfect opportunity for a candlelit cuddle, a trip to Dans Le Noir in London or getting an early night if the kids woke you up early that morning.
Oh and don't forget that daylight saving time starts on Sunday, so put the clock forward before you go to bed (or at least before you turn out the lights - otherwise it can be tricky).
