This chapter examines selected contemporary artworks that (re)construct lost or vanishing animal voices to highlight species extinction and foster awareness of the precarious status of endangered fauna. These artists endow extinct or threatened species with a voice that speaks directly to audiences, evoking emotional responses. They digitally generate imagined animal voices, incorporate archival audio of vanished species, or employ anthropomorphized animal figures that narrate their own disappearance using human speech. Such works underscore that extinction entails not only the loss of sentient individuals but also the erasure of intricate animal cultures and the collapse of diverse, interdependent multispecies relationships. Some artworks function as aesthetic testaments to mass extinction or as expressions of affective mourning for irretrievably lost biodiversity, while others implicitly urge viewers to resist ecological destruction. Across these examples, artists engage creatively with the catastrophe of extinction, composing melancholic soundscapes that memorialize the beauty of what has been lost or advocate for what might yet be saved. In doing so, they counteract extinction’s inherent negation of life – what Deborah Bird Rose terms “double death” and the “great unmaking of life” – and thereby sustain a life-affirming ethos in the midst of environmental collapse.
