Atlanta’s skyline will join buildings around the globe for World Wildlife Fund’s (WWF) annual Earth Hour by turning off non-essential lights on Saturday, March 27, at 8:30 p.m. Households and businesses are asked to do something quite simple — turn off lights for one hour in a call for action on climate change by pledging at www.myearthhour.org.

Earth Hour 2009 gained support from nearly one billion people in 4,100 cities in 87 countries. More than 400 metro Atlanta buildings participated in 2009.

There will entertainment from noon to 3 p.m. featuring the Seed & Feed Marching Abominable, Dem Shelton Boyz, New Knerds, with appearances by Captain Planet, Petunia Garner and Eco Squirrel.
