Before dawn, a team of eight Greenpeace activists climbed the 450 foot smokestack at the Fisk power plant in Chicago.
From the stack, they are demanding that the operators shut down the dirty, dangerous Fisk and Crawford coal plants.
The plants—operated by Edison International subsidiary Midwest Generation—are among the oldest in the United States.
More people live in range of these plants than any other coal plant in America; nearly one in four Chicagoans live in a three mile radius of one or both plants.
