Ecocentrism (/ˌɛkˈsɛntrɪzəm/; from Greek: οἶκος oikos, "house" and κέντρον kentron, "center") is a term used by environmental philosophers and ecologists to denote a nature-centered, as opposed to human-centered (i.e. anthropocentric), system of values. The justification for ecocentrism usually consists in an ontological belief and subsequent ethical claim. The ontological belief denies that there are any existential divisions between human and non-human nature sufficient to claim that humans are either (a) the sole bearers of intrinsic value or (b) possess greater intrinsic value than non-human nature. Thus the subsequent ethical claim is for an equality of intrinsic value across human and non-human nature, or biospherical egalitarianism.[1]
