Concern for rare species has been an important part of environmental activism since the first environmental movements started in the nineteenth century. Now the protection of rare species is a part of the political goal to preserve biodiversity. This book discusses ethical issues connected with the protection of rare species from a virtue-ethical perspective. It explores the following two questions: what constitutes a good human life together with other species and how can it be realized? The book takes account of both Aristotelian and Christian virtue ethics.
