Earth Hour, a global movement since 2007, falls on the last Saturday of March. Every year, people around the world turn off non-essential lights for one hour. Dahua has also joined in this initiative. From Asia, Oceania, and Egypt to Europe, UK, and Brazil, this global blackout event sends a powerful message about protecting the planet.
