Earth Hour is an annual international event organised by WWF (World Wide Fund for Nature), and held on the last Saturday of March, that asks households and businesses to turn off their lights and electrical appliances for one hour to raise awareness towards the need to take action on climate change.

This year, Earth Hour has been transformed into the world’s first global election, between Earth and global warming. For the first time in history, people of all ages, nationalities, race and background have the opportunity to use their light switch as their vote – Switching off your lights is a vote for Earth, or leaving them on is a vote for global warming.
