It's almost time to turn off the lights and unplug electronics.
People from around the world will be taking part in Earth Hour on Saturday night.
The event is celebrated every year in order to bring awareness to climate change and stress the need for protecting the planet.
Earth Hour will start at 8:30pm.
It's not about which country you're from, it's about what ? we're from. Join #EarthHour at 8:30PM wherever you are! #ChangeClimateChange
