ABSTRACT
What is the Terrestrial and how does it change the ethics and politics of sustainability? This chapter engages with the ethical and political questions that arise when we ontologically recompose humans into terrestrials. The Terrestrial is introduced as a new actor in a politics of sustainability that also involves other political attractors such as climate denial, globalism, and localism. The Terrestrial changes our understanding of sustainability through attuning to multiple agencies in the critical zones of what is called Gaia. Becoming Earth-bound is to become in companionship with the movement of these agencies. The Terrestrial dissolves the imagination of separating human and nonhuman worlding. Instead, the Terrestrial entails principles of engendering and learning to become with Gaia.
