In The End of the Anthropocene: Ecocriticism, the Universal Ecosystem, and the Astropocene, Michael J. Gormley examines literary imaginings of the Anthropocene's end and the Astropocene's beginning-when humans are no longer bound to the blue planet on which we evolved. Gormley analyzes literary images of human tracks on Earth, the Moon, and Mars to characterize the late-stage Anthropocene and to explore humanity's role in the universal ecosystem. The End of the Anthropocene uses a predictive and paradigmatic model of ecocriticism, examining science fiction works as interplanetary nature narratives.
