About Earth Hour:
- It is a global grassroots movement uniting people to take action on environmental issues and protect the planet.
- It is organized by World Wildlife Fund (WWF).
- It was started by WWF and partners as a symbolic lights-out event in Sydney in 2007.
- It takes place on the last Saturday of March every year.
- “Earth Hour” encourages people to switch off all lights for an hour, from 8:30 pm to 9:30 pm local time to promote awareness of climate change challenges and energy conservation.
- Governments and companies also participate by turning off non-essential lights in their buildings, monuments, and landmarks to raise awareness about the impact of energy consumption on our planet.
- This symbolic act, known as the ‘lights off’ moment, unites people worldwide in a show of support for the planet and serves as a reminder of the environmental issues facing us.
