Pope Francis wants Catholics to know environmental damage and global warming are “sins against creation.”

Francis’s announcement, entitled “Show Mercy to our Common Home” appealed for “people of faith and goodwill” to come together in “showing mercy to the earth as our common home and cherishing the world in which we live as a place for sharing and communion.”

Francis defined a sin against creation as humans degrading the integrity of the earth by causing changes in the climate or contaminating earth’s waters, land, air and life.

“To commit a crime against the natural world is a sin against ourselves and a sin against God,” the pope said Thursday. “Let us repent of the harm we are doing to our common home.”
