Marine litter

Marine debris, also known as marine litter, is human-created waste that has deliberately or accidentally been released in a sea or ocean. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack. Deliberate disposal of wastes at sea is called ocean dumping (Source: Wikipedia).

海洋垃圾，亦称海洋废弃物，系指人类有意或无意排放至海洋中的废弃物。漂浮在海中的海洋垃圾往往聚集于气旋中心及海岸线附近，频繁地冲上岸边，此时被称为海滩垃圾或潮汐残骸。将废弃物有意投掷入海的行为被称为海洋倾倒（资料来源：维基百科）。
