the annual worldwide Earth Hour campaign

Earth Hour around the world

March 24th marks the 11th annual Earth Hour and to draw attention to climate change.

The initiative began in Australia in 2007 as a grass roots gesture by the World Wildlife Fund (WWF) Australia against man-made carbon dioxide emissions linked to a warming planet.

It involved the switching off of electric lights for an hour in 7,000 cities across more than 180 countries, at 8:30 p.m. local time. This year's theme is "Let Nature Shine", a theme that hopes to unite millions of people and promote sustainable living.
