Marine pollution is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide.

In the result of our daily lives, polluting substances such as plastics, glasses, rubbers flow through sewage, rivers, or directly into the ocean. Negative impacts result from the chemicals, particles, industrial, agricultural, and residential waste, noise, or the spread of invasive organisms that flows into the ocean. From this, a research shows that 80% of marine pollution comes from land. A common factor that leads to pollution is garbage, including simple items such as cigarette butts, plastic bags, bottles, cans, and discarded fishing gear. These objects contribute to contaminating the marine ecosystem and environment.
