Amid escalating climate disruption and deepening religious and political divides, this book argues that Orthodox Christians and Muslims possess untapped resources for ecological leadership and mutual understanding.

While each tradition has generated influential theologies of creation and notable public leadership on environmental care, scholarship and public discourse rarely place their ecological visions into sustained conversation or connect them to concrete frameworks for interreligious cooperation.

Drawing on shared histories of marginalization under modern Western political and intellectual dominance, Andrew Sharp explains why both traditions preserved pre-modern cosmologies in which God, humanity, and nature remain integrally related. He then develops the case for a “new sacred science” that resists reductionist accounts of nature without rejecting scientific inquiry, proposing an ethic of innovation that is accountable to metaphysical and moral horizons. With particular attention to the Middle East as a region where climate pressures intensify existing conflict dynamics, Sharp argues that ecology can become a practical platform for Orthodox Christian–Muslim dialogue that moves from statements to joint action, strengthening civil society collaboration around water, food security, public health, and community resilience.

Designed for scholars and students of religion and ecology, interreligious studies, and environmental humanities, as well as practitioners engaged in faith-based climate initiatives, the book connects theological reasoning to real-world activism. It synthesizes major voices in Orthodox and Islamic environmental thought, highlights existing initiatives and points of contact, and offers a clear blueprint for future dialogue and cooperative projects at local, regional, and global scales. By centering ecology as both a spiritual diagnosis and a shared moral task, Sharp demonstrates how Orthodox Christians and Muslims can contribute distinctive leadership to the planetary climate emergency and to peacemaking efforts where environmental stress is already reshaping communal life.
