The Great Pacific Garbage Patch, also known as the eighth continent, is a collection of marine debris in the North Pacific Ocean. It is located between California and Hawaii and is three times the size of France. The patch is a gyre of marine debris particles, with plastic pollution at sea densely distributed within it. The Ocean Cleanup project claims that the patch covers 1.6 million square kilometres and consists of 45,000–129,000 metric tons of plastic. The patch is a result of ocean or marine pollution gathered by ocean currents, with 86% of the plastics originating from fishing activity. The Great Pacific Garbage Patch is just one of five plastic islands located in the world's oceans, with others found in the Mediterranean, the Caribbean, the North Atlantic, the Indian Ocean, and the South Pacific.

The Great Pacific Garbage Patch is the largest accumulation of plastic in the open ocean
The Great Pacific Garbage Patch (GPGP) is the largest accumulation of plastic in the open ocean. It is located in the central North Pacific Ocean, halfway between Hawaii and California. The GPGP is a gyre of marine debris particles, formed by the North Pacific Subtropical Gyre, which is made up of four currents: the California Current, the North Equatorial Current, the Kuroshio Current, and the North Pacific Current. This gyre acts as a highway for debris, drawing waste material from across the North Pacific, including the coastal waters of North America and Japan.
The GPGP is not a solid mass of plastic but rather a widely dispersed area of microplastics, with larger items such as fishing gear and shoes interspersed. These microplastics are not always visible to the naked eye, and even satellite imagery does not reveal a giant patch of garbage. Instead, the water may appear as a cloudy soup. The patch covers an estimated 1.6 million square kilometres, with a concentration of 10-100 kilograms per square kilometre. It is believed to be rapidly accumulating, increasing tenfold each decade since 1945.
The plastic in the GPGP comes from a variety of sources, including land-based sources such as improper waste disposal and manufacturing products, as well as boats and other marine sources. It is estimated that 80% of the plastic in the GPGP comes from land-based sources, with the remaining 20% coming from marine sources. A 2018 study found that synthetic fishing nets made up nearly half of the mass of the patch, due to ocean current dynamics and increased fishing activity in the Pacific Ocean.
The plastic in the GPGP has severe ecological consequences. Animals migrating through or inhabiting this area are likely to consume plastic, with sea turtles and Laysan albatross chicks from Kure Atoll and Oahu Island having significant amounts of plastic in their diets. As plastic contains Persistent Bio-accumulative Toxic (PBT) chemicals, these chemicals are then ingested by the animals, potentially contaminating the human food chain through a process called bioaccumulation.

It is located in the North Pacific Ocean, between California and Hawaii
The Great Pacific Garbage Patch, also known as the Pacific Trash Vortex or the North Pacific Garbage Patch, is located in the North Pacific Ocean, between California and Hawaii. It is the largest accumulation of plastic in the open ocean, covering an estimated area of 1.6 million square kilometres (0.62 million square miles) and containing 80,000 metric tons of plastic. This plastic patch is not a solid mass but is made up of tiny bits of plastic, called microplastics, with some larger objects intermixed. These microplastics are often microscopic, with a low density of 4 particles per cubic meter, making it impossible to detect by aircraft or satellite imagery.
The Great Pacific Garbage Patch formed gradually due to ocean pollution gathered by ocean currents, specifically the North Pacific Subtropical Gyre. This gyre, formed by four currents (the California, North Equatorial, Kuroshio, and North Pacific currents), acts as a highway that moves and traps waste within its currents, drawing in waste from across the North Pacific, including coastal waters off North America and Japan. The waste is then gradually moved towards the centre of the gyre, where it becomes trapped.
The plastic in this patch comes from a variety of sources, with an estimated 86% originating from fishing activity. A 2014 study found that discarded fishing gear, such as buoys, lines, and nets, accounted for more than 60% of the mass of plastic marine debris. Other sources include improper waste disposal and management of trash and manufacturing products, including single-use plastics and disposable packaging.
The impact of this plastic patch on marine life is significant. Animals migrating through or inhabiting this area are likely to consume plastic, with chemicals from the plastic entering the marine food web and potentially contaminating the human food chain as well. For example, studies have shown that sea turtles and albatross chicks in the area have a significant percentage of their diets composed of ocean plastics. Additionally, fishing nets can entangle and harm marine animals that collide with them.
Efforts to clean up the Great Pacific Garbage Patch are ongoing, with organisations such as The Ocean Cleanup removing millions of kilograms of trash from the patch. Scientists and explorers agree that limiting or eliminating the use of disposable plastics and promoting the use of biodegradable resources are crucial steps in addressing this environmental crisis.

It is made up of microplastics, which are tiny bits of plastic that are often microscopic
The Great Pacific Garbage Patch, also known as the Pacific Trash Vortex or the North Pacific Garbage Patch, is a gyre of marine debris particles in the central North Pacific Ocean. It is not a solid mass of plastic as many people imagine, but rather a widely dispersed area consisting primarily of "fingernail-sized or smaller"—often microscopic—particles in the upper water column known as microplastics. These microplastics are tiny bits of plastic that have broken down from larger pieces of plastic waste, such as discarded fishing gear and single-use plastic items like packaging, straws, and bottles.
Microplastics can be challenging to see with the naked eye, and even satellite imagery cannot detect the Great Pacific Garbage Patch as a solid mass. Instead, the water in the affected area may appear cloudy or soupy, with larger items like fishing gear and shoes intermixed. Despite their small size, microplastics pose a significant threat to marine life and ecosystems. Animals migrating through or inhabiting this area are likely to consume plastic, and the chemicals attached to the plastic can bioaccumulate in their bodies, potentially contaminating the human food chain as well.
The Great Pacific Garbage Patch formed gradually due to ocean currents and pollution, with waste material drawn in from across the North Pacific, including coastal waters off North America and Japan. The buoyant plastic mass is distributed within the top few meters of the ocean, influenced by factors such as wind speed, sea state, and plastic buoyancy. While larger pieces of plastic resurface more rapidly, microplastics can persist in the region for decades or longer, with plastic accumulation in this area predicted as early as 1988.
Efforts to clean up the Great Pacific Garbage Patch have been led by organizations like The Ocean Cleanup, which has removed millions of kilograms of trash from the patch using various systems. Scientists and explorers agree that the best way to address this issue is to limit or eliminate the use of disposable plastics and increase the use of biodegradable resources. Initiatives like the Plastic Free Waters campaign and the work of organizations such as the Plastic Pollution Coalition and the Plastic Oceans Foundation are crucial steps towards reducing the impact of plastic pollution on our oceans and marine life.

The patch is not visible from satellites or aircrafts, despite its massive size
The Great Pacific Garbage Patch, located in the North Pacific Ocean, is the largest accumulation of plastic in the open ocean. It is a gyre of marine debris particles, formed gradually as a result of ocean or marine pollution gathered by ocean currents. The gyre's rotational pattern draws in waste material from across the North Pacific, incorporating coastal waters off North America and Japan.
Despite its massive size, the patch is not visible from satellites or aircraft. This is because the patch is a widely dispersed area consisting primarily of suspended "fingernail-sized or smaller"—often microscopic—particles in the upper water column known as microplastics. These microplastics, which can be smaller than five millimetres in size, are scattered over the surface of the ocean and do not form a solid mass. They can be suspended at or just below the surface of the water, making them almost invisible. While microplastics dominate the area by count, larger objects make up 92% of the patch's mass.
The Ocean Cleanup, an organisation dedicated to removing plastic from the Great Pacific Garbage Patch, has found that the patch covers 1.6 million square kilometres (0.62 million square miles) with a concentration of 10-100 kilograms per square kilometre. They estimate that the patch contains 80,000 metric tons of plastic, with 1.8 trillion plastic pieces.
The patch is believed to have increased "10-fold each decade" since 1945 and is rapidly accumulating. The gyre contains approximately six pounds of plastic for every pound of plankton. The plastic in the patch has been measured since the 1970s, and calculations from subsequent years show that microplastic mass concentration is increasing exponentially.

It is estimated that the patch contains 1.8 trillion plastic pieces and kills thousands of marine animals annually
Marine animals are facing a grave threat due to plastic pollution in the oceans, with thousands of creatures dying annually from ingesting or getting entangled in plastic debris. The Great Pacific Garbage Patch, also known as the Pacific Trash Vortex or North Pacific Garbage Patch, is a stark example of the devastating impact of plastic pollution on marine life. This garbage patch, located in the central North Pacific Ocean, is formed by ocean currents that trap waste material from the North Pacific Gyre, encompassing coastal waters off North America and Japan.
The Great Pacific Garbage Patch is not a solid mass of floating garbage as often imagined, but a widely dispersed area of microplastics, or "fingernail-sized or smaller" particles, suspended in the upper water column. Despite its low density, the patch covers an astonishing 1.6 million square kilometres (620,000 square miles). It is estimated that this patch contains 1.8 trillion plastic pieces, with 92% of its mass made up of objects larger than 0.5 centimetres. This includes items such as plastic lighters, toothbrushes, water bottles, and fishing gear.
The impact of this plastic pollution on marine life is profound. Animals migrating through or inhabiting the area, such as sea turtles and albatross, ingest significant amounts of plastic. For example, Laysan albatross chicks from Kure Atoll and Oahu Island have around 45% of their wet mass composed of plastics from the patch. Sea turtles, by-caught in fisheries within and around the patch, can have up to 74% of their diets consisting of ocean plastics. Furthermore, endangered species such as Hawaiian monk seals and Pacific loggerhead sea turtles are among nearly 700 species that ingest or become entangled in plastic litter, leading to injury and death.
The plastic pollution in the Great Pacific Garbage Patch also has indirect effects on marine life. As plastics break down into smaller pieces, they can be ingested by smaller organisms, leading to bioaccumulation of chemicals in the bodies of animals. These chemicals then move up the food chain, potentially reaching human seafood eaters. Additionally, the presence of plastic debris can interfere with the reproduction of some marine species, further threatening their populations.
Efforts to clean up the Great Pacific Garbage Patch have been undertaken by organisations like The Ocean Cleanup, which had removed over one million pounds of trash from the patch by the end of 2024. However, the patch is believed to be rapidly accumulating, with a tenfold increase predicted each decade since 1945. The persistent nature of plastics and their impact on marine life underscores the urgency of reducing our reliance on disposable plastics and transitioning to biodegradable alternatives.

Frequently asked questions
There are five plastic islands, or garbage patches, located in the oceans. The first one was discovered in the North Pacific in 1997 by American oceanographer Charles Moore. The other four are located in the North Atlantic (discovered in 2009), the Indian Ocean (2010), the South Pacific (2011), and the South Atlantic (2017).
The plastic islands are composed of marine debris, especially plastics that do not biodegrade. Instead, these plastics simply break into smaller and smaller pieces, known as microplastics, which remain in the ocean for decades. Microplastics can be invisible to the naked eye, making the plastic islands difficult to detect by satellite or aircraft.
The size of the plastic islands varies depending on the method of measurement. Estimates range from 700,000 square kilometers (similar to the size of Texas) to more than 15,000,000 square kilometers (approximately twice the size of the United States). The Great Pacific Garbage Patch, located in the North Pacific, is estimated to cover 1.6 million square kilometers, making it larger than France, Spain, and Germany combined.
