Introduction
Bioterrorism has emerged as a prominent fear of the modern age, alongside revolutions in biological science and changing practices of warfare. Bioterrorism is also an important, and often overlooked, site for studying the cultural politics of nature. Nature is at the center of contemporary concerns as never before, but its forms are no longer recognizable in a traditional sense. Massive expenditures on disease control over the last century have been a central site for the production of nature. Institutions of health, war, and science built around modern natures, are setting new terms for biological citizenship and environmental futures for the 21st century. The introduction overviews key histories of bioterrorism and theoretical underpinnings for a critical study of biosecurity.
