As landmarks and homes across the world switched off their lights, we asked you to spend 60 minutes doing something - anything - positive for our planet.
Just 60 minutes? Yes, just one hour. It may not seem like much, but the magic happens when supporters in over 190 countries and territories - all give an hour for our one home, creating the Biggest Hour for Earth.
In 2023, 414,329 people around the world pledged an hour for earth. That's amazing.
