This qualitative study used a deep ecology lens and the New Environmental Paradigm to investigate anthropocentrism and ecocentrism in 30 secondary school environment club students from three schools in Victoria, Australia. The work repositions the deep ecology philosophy as a posthumanist/relational ideology, providing novel perspectives based on kinship with the earth. Open-ended interviews assessed the alignment of attitudes, beliefs, and behaviors along a Deep Ecology Spectrum. Key aspects of deep ecology were confirmed through the study findings including biospherical egalitarianism, limits to growth, wildlife preservation, anti-consumerism, environmental activism, and ecological identity.
