An open access study published in 2022 concluded that 75% up to 86% of the plastic pollution is from fishing and agriculture with most identified emissions originating from Japan, China, South Korea, the US and Taiwan. [1] However, there is evidence naming the U.S. as the third-largest contributor of plastic pollution in coastal environments. [36]
[164] [165] It has been estimated that over 400,000 marine mammals perish annually due to plastic pollution in oceans. [162] Marine organisms get caught in discarded fishing equipment, such as ghost nets. Ropes and nets used to fish are often made of synthetic materials such as nylon, making fishing equipment more durable and buoyant.

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.
Emissions from ships have much more significant environmental effects; many ships go internationally from port to port and are not seen for weeks, contributing to air and water pollution on its voyage. Emission of greenhouse gases displaces the amount of gas that allows for UV-rays through the ozone.
