In the present condition of planetary environmental crises, violence, and war, entire ecosystems are annihilated, habitats turn into unliveable spaces, and shared “more-than-human” vulnerabilities get amplified. Here and now, death and loss become urgent environmental concerns, while the Anthropocene-induced anxiety, anger, and grief are manifested in popular-scientific narratives, art, culture, and activism.Grounded in the theoretical framework of queer death studies, this article explores present grief imaginaries and engagements with more-than-human death, dying, and extinction, as they are interwoven through contemporary art. It is there where an ecological ontology of death is being exposed and ethical territories of eco-grief unfold.
