The conflict between the two countries could erupt in the Barents Sea, which is considered a major place of origin of fish and seafood, for America and for Russia. U.S. and Russian pollock catches here is the bulk of fish catches in the world. But global warming shifts the location of fishing, thereby leading to conflict of interest fishing industries of both countries, as pollock in gradually moving northward into Russian territorial waters. Every summer, the fish moves from the warmer waters of the Aleutian Islands in the more cool waters off the coast of Russia. Scientists have already proved that in the Northern Hemisphere fish moves toward the North Pole in two to three times faster than animals on land. Experts on fishing fear that such movements may lead to a new burst of controversy, reminding cod war 50's and 70's, when fishermen protaranivali ships competitors cut their networks and engage in a gunfight with one another. In the east Mediterranean rapidly declining level of biodiversity that started in the 70's of last century, the reduction of biodiversity in the humid areas of the eastern Mediterranean Sea continues at an accelerated pace and in our time. The program MedWet, dedicated to the conservation of Mediterranean wet areas (lakes, swamps), scientists have studied the Eastern Mediterranean (Israel, Lebanon, Cyprus, Syria, Libya, Egypt, Turkey, Greece and the Balkan countries), and concluded that the numbers of some species, habitats which hitherto were in the eastern Mediterranean, fell significantly in the late 20 th century.
