Earth Hour 2008 was a worldwide event sponsored by the World Wildlife Fund. Going by their local time, people were encouraged to turn off the lights in their home for one hour at 8PM on March 29. The gesture was supposed to symbolize individual commitment to global solutions for climate change.
Criticism
Critics of the event argued that no matter how global a scale, shutting off the lights for one hour will do nothing to impact carbon footprints in any negligible way.TIME: Earth Hour '08 - Did It Matter? (March 27, 2008)
