The increasingly pressing and depressing situation of Planet Earth poses urgent ethical questions for Christians. But, as Cynthia Moe-Lobeda argues, the future of the earth is not simply a matter of protecting species and habitats but of rethinking the very meaning of Christian ethics. The earth crisis cannot be understood apart from the larger human crisis—economic equity, social values, and human purpose are bound up with the planet's survival. In a sense, she says, the whole earth is a moral community.
