What is Earth Hour and why is it so important?

Every March, millions of people around the world come together for one hour to show they care about the future of our planet. From iconic landmarks like Big Ben and the Sydney Opera House to cities across the globe, the lights go out in a stunning display of solidarity for our natural world.  

Why – because our world needs our help. Nature gives us so much, from the food we eat to the air we breathe; it keeps us healthy and thriving. WWF’s Earth Hour is the perfect moment to switch off and give back to the planet. Because when we restore nature, it restores us.
