WWF’s Earth Hour (8.30pm Saturday 31^st March)  A simple idea that’s quickly turned into a global phenomenon. Hundreds of millions of people turning off their lights for one hour, on the same night, all across the planet. It’s about appreciating the brilliant world we all share – and how we need to protect it. Not just for an hour a year, but every day.  More information and sign up at http://earthhour.wwf.org.uk
