The walls of Donna Zofcin's humble Cheyenne, Wyoming, home are an homage to coal with framed watercolor prints of mining equipment. Living in the country's biggest coal state, it's a theme that runs throughout her life – even after her Kentucky coal mining husband passed away. So too, does her Catholic faith.
"Oh, we're very devout," Zofcin said of her and her family, "and we go to church every Sunday."
Pope Francis' recent encyclical on the environment has been both the biggest papal statement ever on the subject and a call for action on climate change. But for the faithful in western coal country, he is raising moral questions.
