Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Plastic pollution is harmful to marine life. Another concern is the runoff of nutrients (nitrogen and phosphorus) from intensive agriculture, and the disposal of untreated or partially treated sewage to rivers and subsequently oceans.
Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the 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.
Larger plastics (called "macroplastics") such as plastic shopping bags can clog the digestive tracts of larger animals when consumed by them [13] and can cause starvation through restricting the movement of food, or by filling the stomach and tricking the animal into thinking it is full. Microplastics on the other hand harm smaller marine life.
The Ocean Conservancy reported that China, Indonesia, Philippines, Thailand, and Vietnam dump more plastic in the sea than all other countries combined. [41] It is estimated that 10% of the plastics in the ocean are nurdles, making them one of the most common types of plastic pollution, along with plastic bags and food containers.

About 46% of the 79 thousand of ghost gear that is the size of many football fields has been found at the Great Pacific Garbage Patch constituted in 2018. [13] The discarded fishing nets and lines kill or inflict myriad marine animals such as fish, sharks, whales, dolphins, sea turtles, seals, and marine birds every year.
Under the cover of darkness, an “elongated” creature moved along the branch of a tree in southern China. Something about the 2-foot-long animal caught the attention of visiting scientists ...
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
