A fine collection of readings, poems, theology and liturgy to help us on our unfinished journey to ecological awareness. 'Give me sustainability, but not yet,' could be our 21st-century version of St Augustine's famous 'continence' prayer. We need to start rethinking our beliefs as if the rest of nature mattered, linking liberation theology with environmental issues, for as the world becomes more uninhabitable, it is the poorest who suffer first and longest. But our relationship with non-human nature is more than just material and economic. We need to start loving nature for its own sake, not just for what we can get out of it, physically, emotionally or spiritually.
