Powerful things happen when people come together. That's why we're inviting you to join millions of others around the world this Earth Hour. By switching off the lights, you'll make a powerful gesture to the planet that you care about its future, and inspire countless others to shine a light on climate action. There are no passengers on spaceship EARTH, we are all crew. We all need nature and the nature needs us. Everyone has a part to play and it starts with a single switch.
