The impact of the pollution has resulted in serious damage to marine environment respectively, thus measures to regulate it is urgently needed. There are growing concerns among the littoral States of the Straits over protecting and preserving the marine environment from vessel-source marine pollution. The adoption of the Law of the Sea Convention and IMO convention namely the International Convention for the Prevention of Pollution from Ships 1973 (MARPOL 73/78) by the littoral States was intended to combat vessel-source pollution effectively in the Straits. The objectives of this article is to address vessel-source marine pollution issues in the Straits and way to regulate them by focussing on the international legal framework for prevention of vessel-source pollution. This paper concludes that the governments of the littoral States are full of zip in legislating pollution prevention instruments with the aim of the Straits to be asserted as a safe waterway for navigation in the future.
