This paper explores the connection and mutual impact between climate change and marine oil pollution.Climate change has severe effects on the Earth's ecosystems and human society,leading to increased occurrences of extreme weather events,glacier melting,rising sea levels,posing challenges to biodiversity,food security,and human health.Simultaneously,marine oil pollution significantly disrupts marine ecosystems,threatening marine life and coastal communities.The paper delves into the impact of climate change on the marine environment and the feedback effects of marine oil pollution on climate change.Furthermore,it analyzes the challenges of current preventive measures and outlines future directions,emphasizing the importance of enhanced international cooperation,implementing environmental policies,developing green technologies,and strengthening public education.In summary,this paper provides theoretical support for devising more effective environmental protection strategies by examining the relationship between climate change and marine oil pollution,fostering deeper considerations and actions towards environmental protection and sustainable development.
