Famous landmarks went dark between 8.30pm and 9.30pm on Saturday as part of the international event organised by conservation charity the World Wildlife Fund (WWF) to urge action to save the planet. It aims to highlight the impact humans are having on the planet through climate change, pollution, plastic and food production. The Palace of Westminster and the London Eye were among the UK landmarks that took part in the initiative this year. Last year's Earth Hour resulted in a 3.5 per cent reduction in electrical demand for the Palace of Westminster and Portcullis House.
