Someone has said that Pope Francis is really a Protestant. He is, if Protestant is defined as someone who protests. His recent encyclical Laudato si' is a protest against the often irresponsible industries as they pollute the environment.
Pope Francis especially protests the ways in which coal is burned in the production of electricity. He is right to protest. What comes out of the smoke stacks of coal-fed electric power plants is linked to 50,000 deaths a year, according to Physicians for Social Responsibility. Because children and the elderly among the poor are the most vulnerable, the pope, following his namesake, St. Francis, has a special concern for those that Jesus calls "the least of these."
