"Laudato Si" (The Care of Our Common Home) addresses the environmental degradation of our earth. Humans are clearly responsible for most of this degradation including global warming, he says. Pope Francis' solution is grounded in faith but he urges dialogue among leaders of all religions, science, economy, politics, and others because the changes required are enormous. These changes involve moving from "extreme consumerism" to a more simple life. This book includes additional resources for the reader to expand his/her knowledge. It also has links to documents cited by Pope Francis and suggestions for group study. It also has a number of reflection questions in many places in the letter.
