This book contains a diverse collection of essays organized around the useful concept of "trans-corporeality," a notion that humans and other life forms are necessarily inscribed within and constituted by social, political, ecological, and technological networks, to name a few, and that they cannot be considered as abstract entities that exist independently in the world. This is an appealing concept - it provides a framework for considering living things that disallows from the get-go various conceptual errors which, Alaimo argues (and I agree), reify and perpetuate the mechanisms of exploitation and injustice that have led to the current terrible state of the biosphere.
For my purposes, the book was at its best in analyzing and motivating this idea, as it did especially in the introduction and the fifth chapter. Alaimo uses the concept to examine various ways that living things evade naive categorization and demonstrate reciprocal influences and exposures that are not necessarily immediately visible.
I planned to write a longer and rather more favorable review of this book, but I have to say the author completely lost my sympathies in the last chapter, where she snidely attacks the major climate researchers Will Steffen, John McNeil, and Paul Crutzen, the latter of whom won the Nobel prize for his work on atmospheric ozone depletion. She refers to their discussion of environmental degradation in a major journal article as “hand-ringing” and claims that their warnings that human activity have impacted the biosphere “appear coated with a veneer of species pride.”
