In this centennial message, Dr. John B. Cobb Jr. issues a heartfelt and urgent appeal for the creation of an ecological civilization—a civilizational transformation rooted in the recognition of humanity’s deep interconnection with the Earth and all forms of life. Drawing on his life’s work in process theology and ecological ethics, Cobb advocates for a shift in worldview that integrates spiritual, economic, educational, and communal dimensions. He critiques dominant economic models grounded in exploitation and calls for sustainable, justice-centered alternatives. Emphasizing the role of faith, interreligious dialogue, and transformative education, Cobb envisions an inclusive, resilient future based on shared responsibility and planetary stewardship. His message is both a reflection on a life of moral and intellectual leadership and a call to collective action in the face of ecological crisis.
