Earlier this week in Chicago, Greenpeace activists occupied the smokestack of one of the dirtiest coal-fired power plants in the United States.

They painted a giant 400 ft. "Quit Coal" message down the side of the stack to draw attention to the fact that coal fired power plants kill between 13,000 and 34,000 people a year from heart disease, cancer, and respiratory illness.

We got some amazing photos from the action and we have opened up the comment section in this post and looking to you to help us choose the best one! We will use the top photo for some upcoming web projects we are launching over the next few months.
