Earth Hour 2010

Turn your lights off for an hour at 8:30 p.m. on Saturday, March 27 to show your concern for climate change: Earth Hour 2010.  People all over the world will turn off their lights at 8:30 p.m. local time. 2010 is the third consecutive year in which the State of Illinois and the City of Chicago are participating, and Chicago’s skyline will once again be in the spotlight. Icons such as the Chicago Theatre, Navy Pier, Willis Tower, Merchandise Mart, the Wrigley Building and Trump International Hotel and Towers will be among the more than 200 downtown buildings turning out their exterior lights.
