Earth Hour is a global movement started by the World Wide Fund for Nature (WWF) in 2007 to bring attention to global climate change. Every year, on the last Saturday in March, people around the world are encouraged to turn off their lights and unnecessary appliances for one hour starting at 20:30 local time. Many companies and organizations, both inside of and outside of the energy sector, support this initiative and use this moment to show their commitment for action on climate change.
The excessive carbon dioxide emissions that are causing climate change continue to pose a great threat to the survival of human beings on the Earth. Only by changing global attitudes towards carbon dioxide emissions can we mitigate the threat to the world.
The Earth Hour 2021 event will start at 8:30 pm (local time) on March 27th.
