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.
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.
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.
Some marine species, such as sea turtles, have been found to contain large proportions of plastics in their stomach. [162] When this occurs, the animal typically starves, because the plastic blocks the animal's digestive tract. [162] Sometimes marine mammals are entangled in plastic products such as nets, which can harm or kill them. [162]
Also, animals can get trapped in the rubbish and be in serious discomfort. For example, the plastic used to hold beverage cans together can get wrapped around animals' necks and cause them to suffocate as they grow. Other instances where animals could be harmed by litter include broken glass lacerating the paws of dogs, cats, and other small ...

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 ...
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.
