|More than 134 countries across the world, including the UK, are switching off their lights for an hour today to support action to create a sustainable future for the planet.
Environment charity WWF has organised the Earth Hour event which will see iconic buildings such as Big Ben, the BT Tower, Buckingham Palace, Windsor Castle, Edinburgh Castle, Clifton Suspension Bridge in Bristol, Stormont in Northern Ireland and Cardiff’s Millennium Centre blacking out for an hour.
The event, which takes place at 8.30pm local time around the world, started in Fiji, New Zealand and Australia.
