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.

The concerns of the international community regarding the potential environmental crisis for future generations have being increased arising out of the intensification of the challenges and threats to the marine environment as well as diminution of the biological resources as a result of the aggregation of harmful human activities over the maritime zones. At the same time, conservation, sustainable use and governance of the oceans through the application of the rule of law is one of the most important issues that have been at the forefront of the international community's endeavor dealing with law of the sea and ocean affairs. The United Nations General Assembly in order to resolve the challenges of the existing legal framework governing marine biodiversity has established a legally binding instrument for conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction known as the BBNJ process within the framework of the Convention on the Law of the Sea (UNCLOS). The present paper, while considering the basic foundations of the existing international legal framework applicable to marine biological diversity in areas beyond national jurisdiction, describes the strengths and weaknesses of the current legal framework in order to improve the ongoing international legally binding instrument concerning BBNJ and will pursue the monitoring of the ongoing process from international law perspectives.

Purpose: Low back pain is one of the most common health problems of the world. Very different causes can cause back pain. Approximately 85% of people who are examined for low back pain the cause is not specific. The purpose of this study is to investigate the effects of the knee abnormalities on pain intensity and functional fitness in middle aged men with the chronic nonspecific low back pain. Method: The statistical community of this study includes 30 people of patient’s male with nonspecific chronic low back pain in the age range of 30-50 years with one of the abnormalities of genu varum or genu valgum. Results: The research findings were analyzed using descriptive and inferential statistical methods (dependent t and independent t tests). The research findings indicate that both the pain and disability of the experimental groups have significantly decreased after applying selected of corrective programs (Stretching muscles and short elements and strengthening weakened muscles). Sitting frog, walking with the inner edges of the legs, pressure to enter the wall with the outer edges of the legs to modify the genu varum. passing legs from one side to another in the form of scissors in liner mode, passing the medicine ball to the wall with the inside of the legs, walking with the outer edges of the legs to modify the genu valgum (p<0.05). While the two variables in the control group did not differ significantly (p>0.05). Conclusions: According to the results and considering the conditions prevailing on the research samples, it can be concluded that knee abnormalities (genu varum and genu valgum) affected by pain intensity and functional fitness efficacy in nonspecific chronic low back pain patients and Corrective exercises of these abnormalities has had a significant effect on reduce pain and disability index.
