Earth Hour 2011 is taking place this Saturday 26th March at 8:30pm local time.
Earth Hour is a campaign run by WWF. The aim is to get people and businesses to simultaneously switch off their lights for an hour, in an attempt to highlight our need to reduce consumption if we are to tackle climate change and save the natural world.
Last year hundreds of millions of people across 128 different countries and territories took part, which is pretty impressive! Will you be taking part this year? You can sign up here.
You can like the Earth Hour Facebook page to demonstrate your support for the campaign and to show the world’s governments how seriously people now consider climate change to be.
I blogged about Earth Hour two years ago here.
