This Saturday, you may have noticed fewer lights on around the place. People living near some of the world’s most iconic monuments would certainly have noticed, as the UN Headquarters, the Eiffel Tower, the Pyramids of Egypt and Christ The Redeemer statue in Rio were all plunged into darkness. These were just a few of the world’s biggest landmarks which participated in the 13th annual Earth Hour alongside individual households.  Closer to home, the Sydney Opera House and Harbour bridge also participated in the event, which aims to raise awareness of Climate Change and the need for everyone to take steps to combat it. Participants also lit ’60+’ signs with candles in reference to the WWF’s shocking October report stating that since 1970, humans have wiped out 60% of all animals with a backbone (mammals, reptiles, birds, fish Amphibians etc.)

The event also saw the lights go out on Singapore’s entire skyline, Berlin’s Brandenburg Gate, the Empire State Building, Saint Peter’s Basilica at the Vatican, The Arc de Triomphe in Paris, Dubai’s Burj Khalifa (the worlds tallest skyscraper), and the Kremlin in Moscow, alongside other monuments, towns and households around the world.
