Considering the relationship between the environment and morality, discussion of the matter of values is inevitable. Although there is no consensus on the intrinsic and instrumental characteristics of the value, the condition of talking about environmental ethics is that the environment carries not instrumental but intrinsic value. The problem of subjectivity of this value creates an ontological problem. Given that the value of what is valued depends on the preferences, interests, and attitudes of the valuers, it can lead to anthropocentric environmental ethics, which is an abusive approach style by environmental policymakers. On the other hand, the understanding that value is independent of the preferences, interests, and attitudes of the subject brings an objective approach but this makes it difficult to base environmental ethics on values ??and adds scientific aspects to environmental approaches. Scientific aspects are already discussed under some concepts such as sustainability, biodiversity, ecology, and environmental management. However, grounding these concepts on moral values ??and the formation of environmental ethics depends on emphasizing not only the scientific and objective but also its subjective side. This study explained the possibility of meeting the universality criterion in objective conditions despite the subjectivity of values because the way environmental ethics is adopted by everyone is only a universal environmental ethic.
