"Life on Earth is facing a mass extinction event of our own making. Human activity is changing the biology and the meaning of extinction. What Is Extinction? examines several key moments that have come to define the terms of extinction over the past two centuries, exploring instances of animal and human finitude and the cultural forms used to document and interpret these events. Offering a critical theory for the critically endangered, Joshua Schuster proposes that different discourses of limits and lastness appear in specific extinction events over time as a response to changing attitudes toward species frailty. Understanding these extinction events also involves examining what happens when the conceptual and cultural forms used to account for species finitude are pressed to their limits as well. Schuster provides close readings of several case studies of extinction that bring together environmental humanities and multispecies methods with media-specific analyses at the terminus of life." --
