Sydney’s Opera House and Bridge plunged into darkness to mark the Earth Hour, as global landmarks began dimming their lights to draw attention to climate change.
Millions of people from some 170 countries took part in the annual bid to highlight global warming caused by the burning of coal, oil and gas to drive cars and power plants.
About Earth Hour
Earth Hour is a worldwide movement organized by the World Wide Fund for Nature (WWF). The event is held annually encouraging individuals, communities, households and businesses to turn off their non-essential lights for one hour, from 8:30 to 9:30 p.m. as a symbol for their commitment to the planet. It was started as a lights-off event in Sydney, Australia, in 2007. Since then, it has grown to engage more than 7,000 cities and towns across 172 countries worldwide.
This year Earth Hour 2016 was held March 25 in 2017 from 8:30 p.m. to 9:30 p.m. during participants' local time.
