In “Laudato si,” known as the Encyclical on the Environment, Pope Francis presents an “urgent challenge” to protect our “common home,” the Earth. I discuss this letter addressed not just to Catholics but to all people, with Christiana Zenner, Associate Professor of Theology, Science and Ethics in the Department of Theology at Fordham University. We talk about Pope Francis’ folding together of his concern for the environment and for the lives of the poor; his framing of the issues in a language of ethics and spirituality and much more.
