The sea of plastic, also known as the Great Pacific Garbage Patch, is a gyre of plastic debris in the north-central Pacific Ocean. It is located from 135°W to 155°W and 35°N to 42°N. The patch covers an estimated surface area of 1.6 million square kilometers, twice the size of Texas or three times the size of France. The Great Pacific Garbage Patch is the largest accumulation of plastic in the world, with plastic pollution affecting marine life and ecosystems. The plastic in the patch comes from a variety of land and ocean-based sources, including improper waste disposal, fishing gear, and single-use plastic items. While the exact amount of plastic in the ocean is unknown, it is estimated that millions of metric tons of plastic enter the ocean each year, with plastic production expected to increase in the coming years. This has led to growing concerns about the impact of plastic pollution on the environment and the need for urgent action to address the issue.

What You'll Learn
The Great Pacific Garbage Patch
The garbage patch is a gyre of marine debris particles, bounded by the North Pacific Subtropical Gyre. The gyre's rotational pattern draws in waste material from across the North Pacific, incorporating coastal waters off North America and Japan. The gyre acts like a highway that moves debris from one patch to another. The circular motion of the gyre draws debris into its stable centre, where it becomes trapped. The entire Great Pacific Garbage Patch is bounded by this gyre. The National Oceanic and Atmospheric Administration (NOAA) defines a gyre as a large system of swirling ocean currents.
The collection of plastic and floating trash originates from the Pacific Rim, including countries in Asia, North America, and South America. A 2015 study reported that the debris floats eastward out of Asian countries, primarily from China, Indonesia, the Philippines, Vietnam, Sri Lanka, and Thailand. China was responsible for approximately 30% of plastic ocean pollution. The patch is believed to have increased "10-fold each decade" since 1945.

Plastic in the ocean is deadly to wildlife
Plastic in the ocean is having a devastating impact on wildlife, with creatures large and small suffering the consequences. The Great Pacific Garbage Patch, also known as the Pacific Trash Vortex or North Pacific Garbage Patch, is a gyre of marine debris particles in the central North Pacific Ocean. It is a stark example of the plastic pollution crisis, with floating trash originating from countries in Asia, North America, and South America. This plastic pollution is not limited to the Great Pacific Garbage Patch, however, as it is estimated that there are now 15 to 51 trillion pieces of plastic in the world's oceans, affecting every square mile of surface ocean.
The effects of this plastic pollution on wildlife are dire. Marine mammals, such as whales, dolphins, and seals, are particularly vulnerable to plastic entanglement and ingestion. Discarded fishing nets and ropes can trap and entangle marine life, leading to injury, starvation, and increased vulnerability to predators. An estimated 300,000 whales, dolphins, and porpoises die each year from ghost gear entanglement. Large pieces of plastic can also smother and break coral reefs, disrupting their healthy growth.
Smaller plastic fragments can be mistaken for food by seabirds and other marine species, leading to suffocation, starvation, and toxic contamination. It is estimated that more than 100,000 marine birds die each year due to plastic ingestion, with 60% of all seabird species having eaten plastic. This number is predicted to rise to 99% by 2050. The impact of plastic ingestion on seabirds is devastating, reducing the storage volume of their stomachs and causing starvation.
Microplastics, which are invisible to the naked eye, are easily consumed by wildlife and can adsorb toxins, transferring them to the fatty tissues of the organisms that ingest them. These microplastics are found throughout the ocean, from the Arctic ice sheets to the sea floor, and their long-term impacts are yet to be fully understood.
The plastic pollution crisis in our oceans is having far-reaching consequences for wildlife, with entanglement, ingestion, and toxic contamination leading to injury and death. From marine mammals to seabirds, no creature is immune to the deadly effects of plastic in the ocean. Urgent action is needed to address this global crisis and protect marine ecosystems.

Plastic waste from China and other Asian countries
The Great Pacific Garbage Patch, also known as the Pacific Trash Vortex or North Pacific Garbage Patch, is a gyre of marine debris particles in the central North Pacific Ocean. It is located roughly from 135°W to 155°W and 35°N to 42°N. The patch covers an estimated surface area of 1.6 million square kilometres, an area twice the size of Texas or three times the size of France. The Great Pacific Garbage Patch is made up of plastic waste from various sources, including Asia, North America, and South America.
China, the world's biggest producer and consumer of plastics, has been a major contributor to plastic waste in the Great Pacific Garbage Patch. In 2017, China was the largest importer of plastic, bringing in almost 600,000 metric tons of plastic waste. A study in 2015 reported that China was responsible for approximately 30% of plastic ocean pollution. The country's domestic plastic pollution is evident, with only about 17% of the plastic used in China being recycled. In 2020, China produced about 60 million tonnes of plastic waste, of which only 16 million tonnes were recycled.
In addition to China, other Asian countries have also contributed significantly to plastic waste in the Great Pacific Garbage Patch. Indonesia, the Philippines, Vietnam, Sri Lanka, and Thailand are among the top countries in the region dumping plastic in the sea. The 2015 study mentioned earlier found that debris floats eastward out of these Asian countries, with China being the largest contributor.
The issue of plastic waste in Asia is not limited to the Great Pacific Garbage Patch. China, for example, has struggled with plastic pollution for decades due to its massive production and consumption of plastics. The country's waste-recycling industry, once a driving force behind its rapid industrialization, has now become a low-profit enterprise that contributes to air and water pollution. To address this issue, China implemented an import ban on solid waste, including plastics, in 2018. While this may have positive environmental effects in the long run, it has also shifted the burden of waste management to other Asian countries, such as Malaysia, Vietnam, and Thailand, which may lack the capacity to handle the increased waste influx effectively.
The plastic waste crisis in Asia and the accumulation of plastic in the Great Pacific Garbage Patch highlight the urgent need for improved waste management practices and a reduction in plastic consumption. The Ocean Cleanup and other organizations are actively working towards cleaning up the patch and advocating for better plastic waste management worldwide.

Improper waste disposal
The GPGP, also known as the Pacific Trash Vortex, is a gyre of marine debris particles, with an estimated surface area of 1.6 million square kilometres. The patch is not a solid mass but consists of microscopic particles known as microplastics, which are often less dense than water, preventing detection by satellites. These microplastics are the result of larger plastics breaking down under the effects of the sun, waves, and marine life. The concentration of microplastics in the GPGP will continue to increase as more plastics are discarded into the environment.
The effects of improper waste disposal extend beyond marine pollution. Land pollution occurs when waste breaks down and seeps into the surrounding soil, making the area dangerous for people and animals. Hazardous chemicals, heavy metals, and other pollutants from industrial waste can contaminate soil, impacting agricultural land, construction sites, and ecosystems. Furthermore, improper disposal methods, such as burning commercial waste, release harmful toxins and greenhouse gases, contributing to air pollution and climate change.
The consequences of improper waste disposal also pose risks for businesses. Failure to comply with commercial and industrial waste management regulations can result in regulatory fines, reputational damage, and operational inefficiencies. Additionally, improper disposal of hazardous waste can lead to health hazards for employees, nearby communities, and customers.
To mitigate these issues, proper waste disposal methods, such as recycling and waste-to-energy solutions, are essential. By implementing recycling programs, businesses can reclaim and reuse resources, reducing their reliance on raw material extraction and promoting sustainability.

Ocean clean-up efforts
The Great Pacific Garbage Patch (GPGP), 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 located roughly from 135°W to 155°W and 35°N to 42°N, with an estimated surface area of 1.6 million square kilometres—twice the size of Texas or three times the size of France. The GPGP is a plastic accumulation zone with over 100,000,000 kilograms of plastic, originating from the Pacific Rim, including countries in Asia, North America, and South America.
The Ocean Cleanup is a non-profit organisation that has been researching, extracting, and monitoring plastic pollution in oceans and rivers globally for over ten years. They aim to remove 90% of plastic from the oceans by 2040 through the development and scaling of ocean cleanup systems and river interception technologies. Their dual strategy involves intercepting plastic in 1000 rivers worldwide to cut the inflow of pollution and cleaning up what has already accumulated in the ocean. The Ocean Cleanup's cleaning technologies are deployed worldwide, with tens of millions of kilograms of plastic removed to date.
The Ocean Cleanup's research team has conducted multiple expeditions and published studies on the vertical distribution of plastic in the GPGP and the North Atlantic Gyre. They found that plastic concentration decreases exponentially with depth, with the highest concentration at the surface, and the buoyant plastic mass distributed within the top few meters of the ocean. The mass concentration model produced from data visualises the plastic distribution in the patch, with the centre concentration levels reaching hundreds of kg/km² while decreasing to 10 kg/km² in the outermost region.
The Ocean Cleanup has also developed an app that enables users to survey the ocean for plastic and report their observations. In addition, they have trialled new technologies such as Trashfence, a river interceptor, and System 002, also known as "Jenny", which was deployed in the GPGP for testing. System 002 actively towed by two ships gathered 28,000 kilograms of trash, and the project has since announced plans for System 03, which will span up to 2.5 km.
While the environmental impact of at-sea plastic removal strategies is still uncertain, the dangers of floating plastic are clear. Floating plastic contributes to the breakdown into microplastics, contaminating marine ecosystems and hindering the ocean's ability to absorb and export carbon. The Ocean Cleanup's operations have a significantly smaller carbon footprint, and their efforts in the GPGP are believed to deliver an environmental net benefit.
