This year, as you switch off your lights on the night of Earth Hour (27 March), we're dropping a must-watch video and inviting you to take one simple action.
Our goal? Re-create the same unmissable sight online by taking over the social media feeds of millions around the world and putting the spotlight on our planet, the issues we face, and our place within it all.
Let's get the world watching.
Let's get the world talking.
Take part in the Earth Hour Virtual Spotlight.
