2The Earth Cries Out describes best practices of faith communities responding to the impending climate and sustainability emergency, and presents the next steps for people of belief in the years following Laudato Si'. Twelve sustainability challenges, ranging from energy and water consumption to land use and socially responsible investing, are each introduced by the cutting-edge sustainability practices of a faith tradition, followed by discussion of the issue's global importance. Far from a litany of sustainability woes, the book is inspired by a vision of communities of faith that are models of sustainable living.
