A mounting body of evidence demonstrates that our generation and our civilization teeter on the brink of a man-made disaster of global scale. Climate change stands as the defining question of our century. Calls to global action are as strident and passionate as the enormity of the situation is grave and consequential. Of particular significance is Pope Francis' encyclical letter "Laudato Si'" on the care for our Common Home. This article discusses some of the main messages from "Laudato Si'" including its call for pedagogical models of "ecological education" or "environmental education". The article is adapted with minor modifications from an address at the opening session of the OIEC World Congress held in New York in June 2019.
