Phenomena expressed as social interests are examined in the study. Two main domains are touched: (1) the battle of written and unwritten law in the field of the manifestation of environmental interest; and (2) the role of the society involved in environmental protection. Problematic points arising in historical ages - including the present one - are highlighted by conceptual means of sociology and philosophy of law, and of comparative law. The author forwards some solution though it might be in contrast to parallel viewpoints.
