This year Earth Hour is at 8:30pm on 25 March 2017. Around the globe, millions of people, businesses, and landmarks will be setting aside an hour to host events, switch off their lights, and make noise for climate change action. But it is so much more than just an hour… over the years, Earth Hour participants have helped make some pretty amazing things happen. From changing laws to funding solar-powered homes they have made a real, positive impact on our planet.
