The aim of environmental humanities is to integrate environmental research carried out in various humanities and social sciences in connection with the knowledge base on the extent of anthropogenic devastation of the planetary system created by the Earth System Sciences. The methodological basis for the constitution of environmental humanities is environmental philosophy, which formulates the principles of internal coexistence of environmental humanities. The need for a holistic, interdisciplinary and transdisciplinary approach to reflecting on the causes and consequences of anthropogenic devastation of the environment has been pointed out by several authors who are associated with the emergence of environmental philosophy, or rather social and political ecology. The work aims to identify key ideological initiatives enabling the establishment of environmental philosophy and to analyze their impact on the constitution of environmental humanities.
