The 2018 Earth Hour will be held under the slogan Vote for Nature. Within the framework of this event, participants will be able to vote for one of three initiatives: protecting natural areas, removing the obstacles hindering the development of alternative energy, and implementing a system of separate waste collection.
The first ever Earth Hour was held in 2007 in Sydney at the initiative of WWF Australia. In 2017, a total of 187 countries and territories took part in the event, turning off the lights at over 3,100 world landmarks.
