We explore how questions related to developing a sustainable humancivilization can be cast in terms of astrobiology. In particular we show howongoing astrobiological studies of the coupled relationship between life,planets and their co-evolution can inform new perspectives and direct newstudies in sustainability science. Using the Drake Equation as a vehicle toexplore the gamut of astrobiology, we focus on its most import factor forsustainability: the mean lifetime <L> of an ensemble of Species withEnergy-Intensive Technology (SWEIT). We then cast the problem into the languageof dynamical system theory and introduce the concept of a trajectory bundle forSWEIT evolution and discuss how astrobiological results usefully inform thecreation of dynamical equations, their constraints and initial conditions.Three specific examples of how astrobiological considerations can be foldedinto discussions of sustainability are discussed: (1) concepts of planetaryhabitability, (2) mass extinctions and their possible relation to the current,so-called Anthropocene epoch, and (3) today's changes in atmospheric chemisty(and the climate change it entails) in the context of pervious epochs ofbiosphere-driven atmospheric and climate alteration (i.e. the Great OxidationEvent).
