The ocean is inundated with trash, and plastic pollution is one of the most pressing environmental issues facing our planet today. Marine debris is pervasive, with plastics found everywhere from the deepest trenches to the most remote Arctic ice sheets. The impact of plastic pollution on marine life is devastating, with nearly 1,300 species documented to have plastics in their bodies and an estimated 1 million marine animals dying each year as a direct result. The majority of plastic pollution in the ocean is caused by littering, with single-use plastic items such as food packaging, plastic bags, and bottles ending up in waterways and eventually the ocean. While the exact amount of plastic in the ocean is difficult to pinpoint, estimates range from 75 to 199 million tons, and the problem is constantly evolving.

What You'll Learn
Mismanaged waste and littering
Marine debris, including plastics, is a significant issue for the world's oceans, with plastic pollution being one of the most pressing environmental concerns. Mismanaged waste and littering are key contributors to this issue. Mismanaged plastic waste (MPW) is defined as plastic material that has been littered, ill-disposed of, or comes from uncontrolled landfills. This waste can enter the ocean through various pathways, including inland waterways, wastewater outflows, wind, and tides.
Littering is a major source of ocean plastic pollution. Single-use plastic items such as food wrappings, plastic bags, razors, and bottles are often not disposed of properly and end up in waterways and, eventually, the ocean. This improper disposal is a significant issue, as plastics can remain in the ocean for a long time, causing harm to marine life and ecosystems.
The impact of mismanaged waste and littering is not limited to the ocean's surface. Plastic debris can sink, be ingested by marine animals, or accumulate in ocean gyres, forming garbage patches. These garbage patches are large areas where trash, fishing gear, and other marine debris collect due to rotating ocean currents called gyres. The Great Pacific Garbage Patch, located between Hawaii and California, is a notable example, containing approximately 100 million kilograms of plastic.
The sources of mismanaged waste contributing to ocean pollution vary globally. While high-income countries generally have effective waste management systems, middle-income countries with growing plastic consumption and inadequate waste management infrastructures face challenges in dealing with the increase in consumption. Identifying these key sources of pollution is crucial for targeted cleanup efforts and policy interventions.
To address the issue of mismanaged waste and littering, local, national, and international efforts are necessary. Initiatives such as the Save Our Seas Act of 2018 aim to promote international action, authorize cleanup responses, and increase coordination among federal agencies. Additionally, organizations like The Ocean Cleanup are dedicated to cleaning up polluting rivers and oceans, as well as tracking pollution levels and optimizing solutions.

Abandoned fishing gear
The ocean is heavily polluted with plastic, which has been found everywhere from the deepest trenches to the most remote Arctic ice sheets. A recent study estimated that there are approximately 171 trillion pieces of plastic floating on the ocean's surface. This plastic pollution is causing widespread harm to marine life, with nearly 1,300 species documented with plastics in their bodies.
The majority of ghost gear is made of long-lasting synthetic materials, such as plastic and metal, which can persist in the environment for many years. Once lost at sea, it wreaks havoc on ocean wildlife indefinitely. While there are no strong estimates of the total amount of ghost gear in the ocean, recent studies indicate that it makes up 46-70% of all floating macroplastics (>5mm in size) in the ocean gyres by weight.
The problem of abandoned fishing gear is widespread, and it can be challenging to determine the source of the gear or who is responsible. However, there are efforts being made to address this issue. The Global Ghost Gear Initiative is an international partnership dedicated to tackling the problem of lost and discarded gear, and it now includes the support of the United States government. Additionally, the NOAA Marine Debris Program funds projects to remove derelict fishing gear and prevent it from entering the ocean, and they offer a free solution for fishers to dispose of old or unusable gear.

Microplastics
The presence of plastic in the ocean is continually increasing, and it is one of the main causes of marine species extinction, health problems for humans and animals, and the destruction of ecosystems. Research states that by 2050, plastic will likely outweigh all the fish in the sea. Marine wildlife suffers the most direct and damaging effects of ocean plastic pollution. From fish to turtles, seals, crustaceans, microorganisms, and many other forms of life, the damage caused by plastic pollution to marine animals is becoming increasingly visible. For example, research indicates that half of the sea turtles worldwide have ingested plastic, mistaking it for food, leading to choking, internal injuries, and starvation.
The durability of plastic means that once it enters the ocean, it will persist for long periods and won't disappear on its own. While new technologies allow for the capture of larger marine debris, microplastics are virtually impossible to reach, especially when they are deep in the ocean. Therefore, the best solution is to prevent plastic waste from entering rivers and seas in the first place. This requires improving plastic waste management worldwide, as currently, only 9% of plastic is recycled, with half going straight to landfill and a further one-fifth being mismanaged, at risk of leaking into waterways.

Plastic production
The ocean is inundated with plastic pollution, from the deepest trenches to the Arctic ice sheets. Marine species are suffering, with plastics found in the guts of sea turtles, whales, and seabirds. The primary source of this pollution is disposable plastic items like food packaging, plastic bags, razors, and bottles, which are not properly disposed of and end up in waterways and, eventually, the ocean. Mismanaged waste, abandoned fishing gear ("ghost gear"), microplastics from synthetic textiles, tire wear, and paint particles also contribute significantly.
The impact of plastic pollution on the ocean is devastating. It is estimated that 8-10 million metric tons of plastic enter the ocean annually, with a recent study placing the figure at 171 trillion pieces floating on the surface. This plastic pollution affects nearly 1,300 marine species, with entanglement, ingestion, and internal injuries being common consequences. The economic costs of this pollution are estimated to be between $6-19 billion USD annually, impacting tourism, fisheries, and clean-up efforts.
While the problem is extensive, there are efforts to combat it. Dozens of national and local governments have implemented policies to reduce disposable plastic use, with Africa leading the way in banning plastic bags. Individuals can also play a role by refusing single-use plastics, advocating for better waste management, and supporting organizations dedicated to ocean conservation and research.

Non-point source pollution
The amount of trash polluting the ocean is difficult to quantify due to the diverse sources of plastics and varying estimates. However, a recent study estimated that there are approximately 171 trillion pieces of plastic floating on the ocean's surface. This figure does not include plastics that have sunk below the surface or become colonized by marine life.
One of the primary sources of ocean pollution is non-point source pollution, which is challenging to address due to its diverse origins. Non-point source pollution refers to any source of water pollution that does not meet the legal definition of "point source" pollution as outlined in the Clean Water Act. Point source pollution, in contrast, originates from a single, identifiable location, such as an oil or chemical spill.
The impact of non-point source pollution on coastal waters has been a focus of federal programs and initiatives, such as the Nonpoint Source Management Program and efforts to protect coastal waters from this type of pollution. Additionally, specific sectors, including agriculture, forestry, boating, and marinas, have been targeted with measures to reduce their contribution to non-point source pollution.
The public also has a role in controlling non-point source pollution. Educational resources and fact sheets provide information on how individuals can help reduce non-point source runoff from their properties. By implementing environmentally sound practices and techniques, the impact of non-point source pollution can be mitigated, contributing to cleaner oceans and healthier marine ecosystems.
