Scientists turn to metaphors to formulate and explain scientific concepts, but an ill-considered metaphor can lead to social misunderstandings and counterproductive policies, Brendon Larson observes in this stimulating book. He explores how metaphors can entangle scientific facts with social values and warns that, particularly in the environmental realm, incautious metaphors can reinforce prevailing values that are inconsistent with desirable sustainability outcomes. Metaphors for Environmental Sustainability draws on four case studies-two from nineteenth-century evolutionary science, and two from contemporary biodiversity science-to reveal how metaphors may shape the possibility of sustainability. Arguing that scientists must assume greater responsibility for their metaphors, and that the rest of us must become more critically aware of them, the author urges more critical reflection on the social dimensions and implications of metaphors while offering practical suggestions for choosing among alternative scientific metaphors

The concept of novel ecosystems (CNE) has been proposed as a way to recognize the extent and value of ecosystems that have been irreversibly transformed by human activity. Although the CNE has recently been subject to critique, existing critiques do not appear to seriously engage with the extent of anthropogenic change to the world's ecosystems. Here, I seek to provide a deeper, philosophical and constructive critique, specifically arguing that the usefulness of the CNE is limited in the following three ways: (1) it is too static, (2) it is too vague, and (3) it is too dualistic. Although the CNE provides some conceptual advance ("new wine"), some of its conceptualization and packaging weakly support this advance ("old wineskins"), so I consider some ways to further develop it, in part to encourage more widespread recognition and appreciation of novel ecosystems.Co-address: Centre for Invasion Biology, Department of Botany and Zoology, Stellenbosch University, South Africa
