The winner of the 2016 Book Prize is Ursula K. Heise’s Imagining Extinction: The Cultural Meanings of Endangered Species (University of Chicago Press). This remarkable, lucid examination of how contemporary culture produces understandings of imperilled nature breaks new ground in its thinking about environmental crisis — local and global — and, particularly, the terms in which we see species loss. This original undertaking brilliantly connects multiple fields of enquiry, philosophical, literary, scientific, political, and investigates genres such as the elegy, the database, and speculative fiction. On matters such as global warming, biodiversity, conservation, non-human justice and the anthropocene, Heise’s thesis is challenging, nuanced and elegantly reasoned, and Imagining Extinction looks set become a celebrated reference point while revealing new directions for the study of culture and biology, literature and science.
