People in 188 countries and territories turned off their lights on Saturday evening to mark the 11th annual Earth Hour, a global initiative that seeks to raise awareness of climate change. The campaign set a new participation record, according to the World Wildlife Fund (WWF), whose Australia branch launched the first event in 2007. Along with individuals darkening their homes, more than 17,900 landmarks and monuments turned out their lights. Those landmarks included Rome’s Colosseum, Paris’ Eiffel Tower, Sydney’s Opera House, and London’s Buckingham Palace.
