Earth Hour

Citizen PSA: Are You Turning Your Lights Out For Earth Hour?

Tonight from 8 p.m. to 9 p.m. local time, major cities around the world are celebrating Earth Hour. Flipping lights off for 60 minutes in a sort of ecological version of the 1980s Hands Across America, organizers hope to unite the world in awareness of the threat of climate change.


Cities like Sydney, Melbourne, and Bangkok (where this picture was snapped) have already fallen dark, and the US is gearing up to join in. A sense of community and ecological awareness is at the heart of the event, though critics are calling the event a gimmick that will have little overall impact.

With energy consumption high on the list of environmental impacts, and states like Maryland possibly facing rolling blackouts as early as 2011, is this event just what the world needs to make the "a-ha!" light bulb go on?

Will you be flipping the switch tonight?
