A passionate book, this is a plea for action before it is too late to save the 11,000 species currently under threat of extinction. The author considers the many habitats currently under threat of destruction, such as coral reefs and mangrove forests, as well as the different types of species threatened. He then looks at the position of the church on these issues and especially the work of Fr Thomas Berry. He follows the historical relationship between church and nature from the Fathers of the Church to the present time. There is a section on current Catholic church teaching, alongside Celtic spirituality.
