A year later, the Earth Hour had become a global sustainability movement with more than 50 million people across 35 countries/territories participating. Global landmarks such as the Sydney Harbour Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco and the Colosseum of Rome, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.
