Belardinelli, S., T. Pievani, 2023, The Ethics of Gaia: Geoethics From an Evolutionary Perspective

In times of unprecedented ecological change led by human activities, a global ethical framework is most needed to support the rapid transformation of current development models, to ensure the protection of human and non-human nature. Geoethics offers such a universal system of values. We assess to what extent geoethics maintains an anthropocentric perspective and examine the ethical challenges raised by this statement, arguing that (i) geoscientific knowledge, which investigates the interrelations between the biotic and abiotic world in a deep-time perspective, should imply the adoption of an eco-centric or even geocentric perspective; (ii) the assumption of an anthropocentric perspective should be outlined more precisely, by clarifying the utilitarian and deontological reasons to maintain a weak anthropocentric approach and to avoid the theoretical bias underlying many anthropocentric narratives. Then, we claim that a non-anthropocentric geoethics would allow a better understanding of the role Homo sapiens as a species plays within the biosphere and geosphere. To provide evidence for our hypothesis, we will discuss two case studies: (i) climate change as a monumental niche construction process, where the ambivalence of human nature is seen in action; (ii) the co-evolution and interconnection between biological and cultural diversity, which support each other in an inextricable link. We claim that a humanistic, eco-centric geoethics can support the necessary transition towards a new conceptual framework in which humans are not separate from, but part of the biosphere. This approach is part of the philosophy of biology, a field that programmatically converges humanities and the life sciences.
