Earth hour is an annual event that takes place on the last Saturday in March. The World Wide Fund (WWF) held the first Earth Hour in Sydney, Australia in 2007, by having over two million homes and businesses switch off non-essential lights and appliances for an hour. The event lowered energy consumption in Sydney by 10% and showed how even small actions can make a difference as our planet struggles to overcome energy and environmental problems created by global warming.
By 2008, over fifty million people in thirty-five countries were taking part in Earth Hour, which even involved turning off the lights on such landmarks as San Francisco’s Golden Gate Bridge and the Colosseum in Rome.
Last year, one hundred and seventy-eight countries and territories ‘switched off’ between 8:30 p.m. and 9:30 p.m. and close to two and a half million individual actions were taken to help #ChangeClimateChange.
