"Survival Dilemma: Cannibalism in Martian Colonies"

In their book "A City on Mars: Can we settle space, should we settle space, and have we really thought this through?", Kelly and Zach Weinersmith explore the ethical dilemma of cannibalism in space. While there is limited literature on the topic, they discuss a self-published paper from 1978 that examines survival homicide in space and the jurisdiction of the state of registry under the Outer Space Treaty. The authors also highlight the unlikelihood of cannibalism in real Mars settlements, as research suggests that people would rather face death together than resort to killing.
