而另一方面，人类活动产生的大部分废物和污染物最终都进入了海洋。全球每年有数十亿吨的淤泥、污水、工业垃圾和化工废物等被直接排入了海洋，河流每年也将近百亿吨0淤泥和废水、废物带入沿海水域，引起沿海生境改变，使动物的栖息和繁殖地遭到破坏。海洋污染的主要来源和比例约是：城市污水和农业径流排放44%，空气污染33%，船舶12%，倾倒垃圾10%，海上油、气生产1%。

On the other hand, most of the wastes and pollutants generated by human activities eventually enter the ocean. Billions of tons of sludge, sewage, industrial waste and chemical waste are directly discharged into the sea every year, and nearly 10 billion tons of 0 sludge, waste water and waste are brought into coastal waters every year, causing changes in coastal habitats and destruction of animal habitats and breeding grounds. The main sources and proportions of marine pollution are about 44% of urban sewage and agricultural runoff, 33% of air pollution, 12% of ships, 10% of garbage dumping and 1% of offshore oil and gas production.

On the other hand, most wastes and pollutants produced by human activities eventually enter the ocean. Every year, billions of tons of sludge, sewage, industrial waste and chemical waste are directly discharged into the sea, and rivers bring nearly tens of billions of tons of sludge, waste water and waste into coastal waters every year, causing changes in coastal habitats and destroying the habitat and breeding grounds of animals. The main sources and proportions of marine pollution are about 44% of urban sewage and agricultural runoff, 33% of air pollution, 12% of ships, 10% of dumping garbage and 1% of offshore oil and gas production.
