Today, Earth Hour was initiated in many cities around the world. Begun last year by citizens in Sydney, Australia, the 60 minute environmental social action project involved about 2 million people who turned the lights off for an hour. This year, again led by citizens in Australia, the earth hour event involved millions more and many cities in a number of countries.
One of the world’s most recognizable sights is the Syndey Harbour, here seen during the Earth Hour.
The event is a powerful example of citizen diplomacy and action, and shows how citizens can be activists in changing behavior and attitudes.
