CONCLUSION:  CONCLUSION Oil transportation through the TSS is increasing, which poses a greater threat to the environment and Marine biodiversity . Oil pollution effects not only the TSS but also the Black Sea and Aegean Sea. The TSS should be declared as a Particularly Sensitive Sea Area (IMO) to be protected internationally. International cooperaiton is needed to protect the biological corridor. Istanbul strait is not an oil high way: it is a refreshment place for residents of Istanbul. Istanbul City is under the threat: museums, mosques, civilization of more than 3000 years is under the threat due to heavy ship traffic and oil transportation in the TSS. Historical fishing grounds are under the threat of oil pollution and ship traffic. Let’s protect Istanbul, TSS, Black Sea and Mediterranean Sea for the future generation!!
