A shot in the dark…
Earth Hour is an event that enables millions of people from across the world to come together in a symbolic and spectacular light outs display, turning their lights off for an hour on 29th March at 20.30 to raise awareness for the planet.
Organised by WWF, it first started as a lights-off event in Sydney, Australia in 2007 and since then it has grown to engage more than 7,000 cities and towns worldwide, and the one-hour event continues to remain the key driver of the now larger movement. You can register to take part in Earth Hour here.
This year, 154 countries are taking part and UK landmarks including Big Ben and the Houses of Parliament in London, Brighton Pier and Edinburgh Castle will all be turning lights off for Earth Hour.
