Start looking out the candles and get ready to turn out the lights at 8.30pm on 25 March 2017 to celebrate WWF’s Earth Hour.

Giant letters are erected at The Kelpies in Falkirk to mark the 10th year of WWF’s Earth Hour. Many of Scotland’s most iconic landmarks including Edinburgh Castle, The Kelpies and Forth Bridge will be switching off their lights on Saturday 25 March at 8.30pm joining global landmarks like the Eiffel Tower, Empire State Building, and Sydney Opera House to show they care about the effects of climate change on people and nature. Since 2007, millions of people in 178 countries across the world have joined together in an hour of unity to show they want continued action on climate change. (Photograph: MAVERICK PHOTO AGENCY)
