Plastic debris in the ocean poses a critical threat to marine ecosystems and coastal communities worldwide. From floating plastics to sunken wreckage, understanding the fate of debris in the sea is crucial in combating marine pollution. This article explores ocean debris’s diverse pathways and environmental impacts, calling for urgent solutions. The ocean accumulates a wide array of debris, mainly from human activities. Plastic, one of the most pervasive pollutants, includes bottles, bags, and microplastics. Abandoned or lost fishing gear, like nets and lines, constitutes a significant portion of marine litter, causing entanglement hazards for marine life. Other human-made materials like glass, metal, and rubber find their way into the ocean, posing environmental risks. Understanding these diverse types of debris is essential for devising effective strategies to combat ocean pollution and protect marine ecosystems.
