People photograph a mural depicting Pope Francis cleaning pollution from the sky, painted on a wall of Albano, near Rome, on Sept. 21, 2019. The mural, by artist Maupal, or Mauro Pallotta, is named "Exemplum Omnibus" (Example for All) and was inspired by the encyclical "Laudato Si'" (Praise Be), which declared an urgent need for the political and spiritual conversion of global leaders and individuals to dedicate themselves to curbing climate change and ending policies and personal habits that destroy creation.
