Abstract
This paper studies an attempt to replicate the Earth’s biosphere in the second half of the twentieth century with the aim of preserving and refashioning the environment as a self‐reproducing ecological system. Ecosystems dynamics framed the planet Earth as a closed system and directed scientific attention to questions of global environmental management. The image of the Earth as a spacecraft and operable in a similar way supported ideas of placing the environment in a laboratory setting. Using the case of Biosphere 2, launched in the Arizona desert in 1983, this paper studies the images of nature and environment contained in this quest to create an ecosystem and human habitat as good as, or superior to nature on Earth (known in this context as Biosphere 1). The second biosphere was designed as ‘a prototype for a space colony’ that would eventually enable its deteriorating predecessor, the Earthly biosphere, to reproduce and allow human settler societies to migrate to other planets. The paper draws on the cultural history of the ship in Western culture and on ships and spaceships as archetypes of autarkic enclosures set apart from nature. It argues that Biosphere 2 as an example of a technologically controlled endosphere advanced an understanding of the environment as a ‘life support system’ that emphasized not completeness but systems integrity, and was based on principles of functionality and replaceability. The paper will explore how notions of biospheric life support shaped demands on the natural and social environments in Biosphere 2 and Biosphere 1.
