Ocean pollution is garbage or chemicals that are spilled into the ocean. Plastics and fertilizers are the most common forms of ocean pollution.
Industrial effluents.
The most common type of ocean pollution is garbage or sewage. They are readily dumped into the ocean by ships and countries located along the ocean.
Most ocean pollution originates from land-based sources, with significant contributions from agricultural runoff, industrial discharges, and urban stormwater. Plastics, chemicals, and fertilizers often wash into waterways and ultimately reach the ocean. Additionally, maritime activities, such as shipping and oil spills, also contribute to marine pollution. The cumulative effects of these sources severely impact marine ecosystems and wildlife.
Ocean pollution is most prevalent in densely populated coastal areas, particularly in regions like Southeast Asia, the Caribbean, and parts of the Mediterranean. The Great Pacific Garbage Patch, located between Hawaii and California, is also a significant area of concentrated plastic debris. Additionally, river systems, such as the Ganges and the Yangtze, contribute heavily to ocean pollution by funneling waste and plastics into the sea. Urban runoff, industrial discharge, and maritime activities exacerbate these issues in these vulnerable regions.
Ocean pollution occurs when harmful effects, or potentially harmful effects, can result from the entry into the ocean of chemicals, particles, industrial, agricultural and residential waste, noise, or the spread of invasive organisms.
The most severe forms of ocean pollution include oil spills, plastic pollution, and chemical waste discharge. These types of pollution can have devastating effects on marine life, ecosystems, and human health, making them critical issues that require urgent attention and action.
Transportation
Some animals, such as sea otters and certain species of fish, help control ocean pollution by consuming algae and controlling its overgrowth. Additionally, filter feeders like mussels and oysters can help clean up water by filtering out contaminants. Ultimately, a healthy and diverse ocean ecosystem can contribute to reducing pollution levels.
