摘要

Marine pollution threatens ocean ecosystems and human health through eutrophication, bioaccumulation, and habitat degradation. This article discusses chemical contaminants, nutrient pollution and eutrophication, marine debris, ocean noise pollution, global and regional hotspots of ocean pollution, the impact of pollution on marine biodiversity, mitigation strategies and global effects, restoration and cleanup efforts, and challenges and future outlooks in marine pollution. The excess nutrient levels disturb ecological balances, cause harmful algal blooms, and threaten biodiversity and coastal economies. While plastic pollution has received widespread attention, marine debris also includes non-plastic materials such as metal, glass, rubber, and textiles. Ocean noise pollution, primarily from shipping, seismic exploration, and military sonar, significantly disrupts marine ecosystems by interfering with the communication, navigation, and behavioral patterns of marine species. The buildup of plastic gyres such as the Great Pacific Garbage Patch is a key contributor to global ocean pollution. Remote polar regions can also show significant accumulation of pollutants due to long-distance marine and atmospheric transportation. Multi-faceted and integrated approaches, such as global regulatory frameworks, technological innovation, waste management improvement, and public engagement, are required to decrease ocean pollution. The growing awareness of marine pollution, especially for plastic debris, has fueled the pick-up trash before it disperses into the open ocean. Meanwhile, ecosystem restoration, ranging from mangrove replanting to coral reef rehabilitation, is crucial in rebuilding degraded marine habitats and promoting resilience to subsequent environmental and climatic pressures.
