At 8.30pm this Saturday it is global earth hour, where people all over the world will be turning off their lights and pledging their support for the planet. This won't be a problem at all for Delia, who told us some time ago how she's helping tackle climate change. Please take care if trying this at home though, Delia does eat a lot of carrots. It's probably also best to keep your eyes open.
Earth Hour started in 2007 in Sydney, Australia when 2.2 million individuals and more than 2,000 businesses turned their lights off to take a stand against climate change. Earth Hour 2010 was the biggest yet, with a record 128 countries and territories joining in the global display of climate action.
