Studying the impact of pollutants on marine ecosystems is significant because it reveals how substances such as heavy metals, plastics, and nutrients disrupt the health of marine life. Pollutants can alter food webs, harm biodiversity, and affect water quality. Additionally, understanding these effects is essential for developing effective conservation strategies and regulations to protect marine environments, which are vital for global climate regulation and human livelihoods. By assessing the links between pollution and ecosystem health, we can implement interventions to mitigate harm and promote marine recovery, thereby fostering sustainable use of ocean resources.
