Earth Hour

More than 134 countries across the world, including the UK, switched off their lights for an hour on Sunday to support action to create a sustainable future for the planet.
Environmental charity World Wildlife Fund has organised the Earth Hour event which saw 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 outfor an hour.
The event, which took place at 8.30pm Sunday around the world, started in Fiji, New Zealand and Australia.
The aim is to highlight the charity's call on governments, organisations and individuals to pledge their commitment to tackling climate change.
