The lights will go out in more than 7000 cities in 190 countries and territories around the world to mark Earth Hour this weekend.

Millions of people are set to switch off their lights for 60 minutes at 8.30pm on Saturday, March 26, in a symbolic* movement to save the planet.

The global event aims to raise awareness about climate change and calls for stronger action to combat the climate crisis.

Energy use – including lighting our homes and other buildings – is the main cause of human-made greenhouse gases* that are being released into Earth’s atmosphere*, causing global temperatures to rise.

Turning off the electric lights for one hour is a chance to think about how much energy we use, the impact this is having on Earth and ways we can reduce this harmful impact.

The 2022 Earth Hour theme is #ShapeOurFuture. It encourages all people to play a part in reducing climate change.

“There’s never been a more critical time for us to come together to protect our planet and shape our future,” said World Wildlife Fund (WWF) Australia chief executive Dermot O’Gorman.

“The future for koalas, the Great Barrier Reef and the Murray Darling River system is bleak* unless we take steps today to address the effects of climate change, which is already having a huge impact on our beloved animals and landscapes.”

The recent devastating floods in NSW and Queensland and another mass bleaching event on the Great Barrier Reef have further highlighted the impact of climate change in Australia.

International landmarks turn off the lights for Earth Hour

Earth Hour was created by WWF and started in Sydney in 2007. Since then it has spread to more than 190 countries and territories and become one of the world’s largest grassroots* movements for the environment.

The event has always focused on climate change but has recently also highlighted the loss of nature. It aims to encourage individuals to take action and then harness* the collective* power of all of these individuals to drive change.

“Earth Hour reminds us that small actions add up – and can make a big difference,” said WWF ambassador, singer and swimmer Cody Simpson.

“When we make changes in our own lives, talk about it and call for a change, we inspire change around us.”

Famous landmarks around the globe will fall into darkness for Earth Hour this year, including the Harbour Bridge and Opera House in Sydney, the London Eye, the Eiffel Tower in Paris, the Colosseum in Rome, New York’s Empire State Building, Cairo’s pyramids and Rio’s Christ the Redeemer statue.

There are lots of ways kids can take action to help our climate, including turning off the lights in your home for Earth Hour on Saturday night and using that time to talk to your family about climate change.

Here are some other suggested ways you can make a difference to the environment:

  • create a worm farm
  • use compost bins
  • plant a vegetable garden
  • plant trees and flowers in your garden that attract bees and pollinating* birds
  • reduce, reuse and recycle the items you use

How kids can make a difference to climate change

1. A lesson through time!
Create a time capsule. Find an old container. This could be a shoebox, a jar, jewellery box etc. but make sure it’s recycled! Write a letter to your future self containing three pledges that you will make now, to help the environment and the future of the world. Draw a picture of how you would like the world to look when you open the time capsule. Continue to fill the container with keepsakes such as photos and trinkets. Then, keep the time capsule in a very safe place (or bury it!) and open in 10 years.
