The growing danger of plastic pollution and its catastrophic effects on marine ecosystems highlight the pressing need for creative approaches to water governance as well as a thorough legal framework. Marine pollution comprises a mixture of chemicals and debris, primarily originating from terrestrial sources and finding its way into the ocean through runoff or wind dispersion. Also, the typical forms of marine debris encompass a range of plastic items such as shopping bags, beverage bottles, cigarette butts, bottle caps, food wrappers and fishing gear. In line with the objectives of Sustainable Development Goal 14 (SDG 14) Life Below Water, this chapter explores methods that can be scaled up to mitigate and eventually eradicate marine pollution by integrates policy assessments, legal framework and water governance tactics via an interdisciplinary approach to suggest practical for addressing this worldwide water pollution issue.
