Join millions of people globally, switching lights off for an hour to raise awareness for the planet. Earth Hour is an recurring annual event initiated by the WWF. Cities all around South Africa have called upon their residents to switch of the lights in order to show their commitment to the fight against climate change. In Johannesburg for example, all public buildings and landmarks will go dark during the hour. An Earth Hour Concert will be held in Soweto, while the Joburg Zoo in Parkview will have a public lights out at the zoo camp. At the Orlando West Regional Park, the official South African Earth Hour celebrations will be held.
