Environment

The Catholic Church has a long history of advocacy for the natural environment, beginning with the ecologically conscious ministry of St. Francis of Assisi. Most recently, the Church’s position has been articulated by Pope Francis in his encyclicals, Laudato Si and Laudate Deum. These documents discuss at length the importance of the natural environment and express the Church's concern with the threat to the natural and human environments from increasing temperatures caused by greenhouse gases.

These encyclicals also emphasize the importance of all life, from the smallest microbes to the largest mammals. Protecting all human life, including those in utero, is an essential component of the Church’s perspective on environmental protection. These concepts are embraced by the Church’s advocacy of caring for all, with a preferential option for the poor and vulnerable.
