Switching off your lights for Earth Hour is a symbolic gesture to promote climate action.
ADVERTISEMENTSwitching off the lights for an hour - a simple idea that will bring millions of people together this year to celebrate what is known as Earth Hour.
Organised by the World Wildlife Fund (WWF), this 60-minute celebration of our planet will take place on 25 March this year.
Earth Hour has been uniting people all over the world, in more than 190 countries, since 2007.
This year, on the last Saturday in March, communities and businesses will switch off their lights between 8.30 and 9.30pm local time to show care and support for planet Earth.
In previous years, lights were even turned off on the Eiffel Tower in Paris, the Sydney Opera House and the ancient Acropolis in Athens.
As well as turning off your lights, you are encouraged to get involved in other activities to promote climate action on this day.
The organisers have put together a list of 20 ways you can take part.
