Support WWF's Earth Hour campaign with their Lights Off campaign on Saturday 19th March 8.30-9.30pm. We want more museums to sign up in the UK this year. Share your museum's involvement on Twitter @earthhour using #earthhour and #sefm.
Earth Hour began in Sydney in 2007 and has quickly evolved to become a global platform for action on climate change. Turning your lights off has become a symbol of people's concern to protect the planet.
