Both science and religion are challenged by the environmental crisis, both to reevaluate the natural world and to reevaluate their dialogue with each other. Many theologians and ethicists have become persuaded that religion needs to pay more attention to ecology, and many ecologists recognize religious dimensions to caring for nature and to addressing the ecological crisis. Somewhat ironically, just when humans, with their increasing industry and technology, seemed further and further from nature, having more knowledge about natural processes and more power to manage them, just when humans were more and more rebuilding their environments, thinking perhaps to escape nature, the natural world has emerged as a focus of concern. This article examines issues surrounding value in nature; the connections between science, conscience, and conservation; Eastern and indigenous faiths; nature and human nature; ecology as a science and its joining with human ecology, where the religious dimension is more evident; environmental justice; and humans are moral agents.
