Pope Francis visited the Naples region in southern Italy which is the stronghold of the Camorra or Neapolitan Mafia, and spoke against its waste dumping and other environmental crimes as reported by James Mackenzie for Reuters:
During a televised open air mass before around 200,000 people, Francis said that the love of God meant respecting life, the environment and nature. "I know that you suffer for these things," he said in an impromptu remarks during his homily in front of the Reggia di Caserta, the former palace of the old Bourbon kings of Naples. "It is particularly important in this beautiful region of yours which requires being protected and conserved, it requires us to have the courage to say no to any form of corruption and illegality," he said to applause from the crowd. "We all know what the name of these forms of corruption and illegality are," he said.
Last month Pope Francis visited the Calabria region where the drug-trafficking 'Ndrangheta rules, and he courageously excommunicated the mobsters for their evil ways.
