Environmental risks and conflicts in the framework of the relations between countries and subsequently their role-playing in interaction and collaboration or conflicts and struggles between political actors especially in the level of states have reproduced serious discussions and disputes on the environment, security, and power which are interpreted as environmental geopolitics or ecopolitics by modern political geography. Geographically, the Persian Gulf is a semi-enclosed sea that has a very low capacity of self-dredging in comparison to that of high seas; hence, it retains the pollutants for longer periods of time. Some of its environmental problems arise from the various activities of the people residing along the northern and southern shores. If the situation is exacerbated by the factors such as oil and its subsequent pollutions, militarism and its subsequent destruction, desalination of seawater, and the construction of artificial islands, one can conclude that regional convergence between the countries neighboring this body of water in the process of bioregionalism would be of an essential necessity. According to the research findings, states acting in the geopolitical region of the Persian Gulf to produce power, security and to sustain them, from one hand, and to protect this shared aquatic ecosystem in the event of sustainable development, from the other hand, should mobilize all collective cooperations and operationalize the bioregionalism in regional and supranational scales.
