Sign up for the WWF's Earth Hour on March 28th to help demonstrate to the leaders of the world that we want them to take action on climate change.

Sign up and switch your lights off for an hour from 8.30pm that day to take part in what the WWF are hoping will be the largest mass participation event ever! Details below.
