The McDevitt Center's initiative devoted to Sustaining Earth is motivated by our sense of the urgency of the growing threats to our environment and by our conviction that a full understanding of these threats and effective responses to them must draw upon both scientific and broadly religious insights and perspectives. Through the public events in this initiative, we aim to provide a wide audience of students, faculty, and members of the regional community with accurate and up-to-date information about the threats, their causes, and measures to meet these threats.
