The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean discovered between 1985 and 1988. It is located roughly between 135°W to 155°W and 35°N and 42°N.[1] The patch extends over an indeterminate area of widely varying range depending on the degree of plastic concentration used to define the affected area.
The patch is characterized by exceptionally high relative concentrations of pelagic plastics, chemical sludge and other debris that have been trapped by the currents of the North Pacific Gyre.[2] Its low density (4 particles per cubic meter) prevents detection by satellite photography, or even by casual boaters or divers in the area. It consists primarily of a small increase in suspended, often microscopic, particles in the upper water column.

Further north, water moves east to Central America, and then joins a larger movement further north, which loops south, west, north, and east between North America and Japan. Two smaller loops circle in the eastern and central North Pacific.
The Patch is created in the gyre of the North Pacific Subtropical Convergence Zone
The great Pacific garbage patch was described in a 1988 paper published by the National Oceanic and Atmospheric Administration (NOAA) of the United States. The description was based on results obtained by several Alaska-based researchers between 1985 and 1988 that measured neustonic plastic in the North Pacific Ocean.[3]Researchers found high concentrations of marine debris accumulating in regions governed by ocean currents. Extrapolating from findings in the Sea of Japan, the researchers hypothesized that similar conditions would occur in other parts of the Pacific where prevailing currents were favorable to the creation of relatively stable waters. They specifically indicated the North Pacific Gyre.[4]
Charles J. Moore, returning home through the North Pacific Gyre after competing in the Transpac sailing race in 1999, claimed to have come upon an enormous stretch of floating debris. Moore alerted the oceanographer Curtis Ebbesmeyer, who subsequently dubbed the region the "Eastern Garbage Patch" (EGP).[5] The area is frequently featured in media reports as an exceptional example of marine pollution.[6]
The patch is not easily visible, because it consists of tiny pieces almost invisible to the naked eye.[7] Most of its contents are suspended beneath the surface of the ocean,[8]and the relatively low density of the plastic debris is, according to one scientific study, 5.1 kilograms per square kilometer of ocean area (5.1 mg/m2).[9]
A similar patch of floating plastic debris is found in the Atlantic Ocean, called the North Atlantic garbage patch.[10][11]

It is thought that, like other areas of concentrated marine debris in the world's oceans, the Great Pacific garbage patch formed gradually as a result of ocean or marine pollution gathered by oceanic currents.[12] The garbage patch occupies a large and relatively stationary region of the North Pacific Ocean bound by the North Pacific Gyre (a remote area commonly referred to as the horse latitudes). The gyre's rotational pattern draws in waste material from across the North Pacific Ocean, including coastal waters off North America and Japan. As material is captured in the currents, wind-driven surface currents gradually move floating debris toward the center, trapping it in the region.
There is no strong scientific data concerning the origins of pelagic plastics.[dubious ][citation needed] In a study published in 2014,[13] researchers sampled 1571 locations throughout the worlds oceans, and determined that discarded fishing gear such as buoys, lines, and nets accounted for more than 60%[14] of the mass of plastic marine debris. The figure that an estimated 80% of the garbage comes from land-based sources and 20% from ships is derived from an unsubstantiated estimate.[15] According to a 2011 EPA report, "The primary source of marine debris is the improper waste disposal or management of trash and manufacturing products, including plastics (e.g., littering, illegal dumping) ... Debris is generated on land at marinas, ports, rivers, harbors, docks, and storm drains. Debris is generated at sea from fishing vessels, stationary platforms and cargo ships."[16] Pollutants range in size from abandoned fishing nets to micro-pellets used in abrasive cleaners.[17] Currents carry debris from the west coast of North America to the gyre in about six years,[18] and debris from the east coast of Asia in a year or less.[19][20]

Estimates of size

The size of the patch is unknown, because large items readily visible from a boat deck are uncommon. Most debris consists of small plastic particles suspended at or just below the surface, making it difficult to accurately detect by aircraft or satellite. Instead, the size of the patch is determined by sampling. Estimates of size range from 700,000 square kilometres (270,000 sq mi) (about the size of Texas) to more than 15,000,000 square kilometres (5,800,000 sq mi) (0.4% to 8% of the size of the Pacific Ocean), or, in some media reports, up to "twice the size of the continental United States".[21] Such estimates, however, are conjectural given the complexities of sampling and the need to assess findings against other areas. Further, although the size of the patch is determined by a higher-than-normal degree of concentration of pelagic debris, there is no standard for determining the boundary between "normal" and "elevated" levels of pollutants to provide a firm estimate of the affected area.
Net-based surveys are less subjective than direct observations but are limited regarding the area that can be sampled (net apertures 1–2 m and ships typically have to slow down to deploy nets, requiring dedicated ship's time). The plastic debris sampled is determined by net mesh size, with similar mesh sizes required to make meaningful comparisons among studies. Floating debris typically is sampled with a neuston or manta trawl net lined with 0.33 mm mesh. Given the very high level of spatial clumping in marine litter, large numbers of net tows are required to adequately characterize the average abundance of litter at sea. Long-term changes in plastic meso-litter have been reported using surface net tows: in the North Pacific Subtropical Gyre in 1999, plastic abundance was 335 000 items/km2 and 5.1 kg/km2, roughly an order of magnitude greater than samples collected in the 1980s. Similar dramatic increases in plastic debris have been reported off Japan. However, caution is needed in interpreting such findings, because of the problems of extreme spatial heterogeneity, and the need to compare samples from equivalent water masses, which is to say that, if an examination of the same parcel of water a week apart is conducted, an order of magnitude change in plastic concentration could be observed.[22]
In August 2009, the Scripps Institution of Oceanography/Project Kaisei SEAPLEX survey mission of the Gyre found that plastic debris was present in 100 consecutive samples taken at varying depths and net sizes along a 1,700 miles (2,700 km) path through the patch. The survey also confirmed that, although the debris field does contain large pieces, it is on the whole made up of smaller items that increase in concentration toward the Gyre's centre, and these 'confetti-like' pieces are clearly visible just beneath the surface. Although many media and advocacy reports have suggested that the patch extends over an area larger than the continental U.S., recent research sponsored by the National Science Foundation suggests the affected area may be much smaller.[22][23][24] Recent data collected from Pacific albatross populations suggest there may be two distinct zones of concentrated debris in the Pacific.[25]

Photodegradation of plastics

Main article: Photodegradation

Washed up plastic waste on a beach in Singapore.
The Great Pacific garbage patch has one of the highest levels known of plastic particulate suspended in the upper water column. As a result, it is one of several oceanic regions where researchers have studied the effects and impact of plastic photodegradation in the neustonic layer of water.[26] Unlike organic debris, which biodegrades, the photodegraded plastic disintegrates into ever smaller pieces while remaining a polymer. This process continues down to the molecular level.[27] As the plastic flotsam photodegrades into smaller and smaller pieces, it concentrates in the upper water column. As it disintegrates, the plastic ultimately becomes small enough to be ingested by aquatic organisms that reside near the ocean's surface. In this way, plastic may become concentrated in neuston, thereby entering the food chain.
Some plastics decompose within a year of entering the water, leaching potentially toxic chemicals such as bisphenol APCBs, and derivatives of polystyrene.[28]
The process of disintegration means that the plastic particulate in much of the affected region is too small to be seen. In a 2001 study, researchers (including Charles Moore) found concentrations of plastic particles at 334,721 pieces per km2 with a mean mass of 5,114 grams (11.27 lbs) per km2, in the neuston. Assuming each particle of plastic averaged 5 mm × 5 mm × 1 mm, this would amount to only 8 m2 per km2 due to small particulates. Nonetheless, this represents a high amount with respect to the overall ecology of the neuston. In many of the sampled areas, the overall concentration of plastics was seven times greater than the concentration of zooplankton. Samples collected at deeper points in the water column found much lower concentrations of plastic particles (primarily monofilament fishing line pieces).[9]

Effect on wildlife and humans

Some of these long-lasting plastics end up in the stomachs of marine animals, and their young,[5][29][30] including sea turtles and the black-footed albatrossMidway Atoll receives substantial amounts of marine debris from the patch. Of the 1.5 million Laysan albatrosses that inhabit Midway, nearly all are likely to have plastic in their digestive system.[31] Approximately one-third of their chicks die, and many of those deaths are due to being fed plastic from their parents.[32][33] Twenty tons of plastic debris washes up on Midway every year with five tons of that debris being fed to albatross chicks.[34]
Besides the particles' danger to wildlife, on the microscopic level the floating debris can absorb organic pollutants from seawater, including PCBsDDT, and PAHs.[35] Aside from toxic effects,[36] when ingested, some of these are mistaken by the endocrine system as estradiol, causing hormone disruption in the affected animal.[33] These toxin-containing plastic pieces are also eaten by jellyfish, which are then eaten by fish.
Many of these fish are then consumed by humans, resulting in their ingestion of toxic chemicals.[37]
Marine plastics also facilitate the spread of invasive species that attach to floating plastic in one region and drift long distances to colonize other ecosystems.[17]
While eating their normal sources of food, plastic ingestion can be unavoidable or the animal may mistake the plastic as a food source.[38][39][40][41][42]
Research has shown that this plastic marine debris affects at least 267 species worldwide.[43]


There has been some controversy surrounding the use of the term "garbage patch" and photos taken off the coast of Manila in the Philippines in attempts to portray the patch in the media often misrepresenting the true scope of the problem and what could be done to solve it. Dr Angelicque White, Associate Professor at Oregon State University, who has studied the "garbage patch" in depth, warns that “the use of the phrase ‘garbage patch’ is misleading. ... It is not visible from space; there are no islands of trash; it is more akin to a diffuse soup of plastic floating in our oceans." In the article Dr. White and Professor Tamara Galloway, from the University of Exeter, call for regulation and cleanup and state that the focus should be on stemming the flow of plastic into the ocean from coastal sources. [44]

Cleanup research

In April 2008, Richard Sundance Owen, a building contractor and scuba dive instructor, formed the Environmental Cleanup Coalition (ECC) to address the issue of North Pacific pollution. ECC collaborates with other groups to identify methods to safely remove plastic and persistent organic pollutants from the oceans.[45][46] The JUNK raft project was a trans-Pacific sailing voyage from June to August 2008 made to highlight the plastic in the patch, organized by the Algalita Marine Research Foundation.[47][48][49]
Project Kaisei, a project to study and clean up the garbage patch, launched in March 2009. In August 2009, two project vessels, the New Horizon and the Kaisei, embarked on a voyage to research the patch and determine the feasibility of commercial scale collection and recycling.[50] The SEAPLEX expedition, a group of researchers from Scripps Institution of Oceanography, spent 19 days on the ocean in August, 2009 researching the patch. Their primary goal was to describe the abundance and distribution of plastic in the gyre in the most rigorous study to date. Researchers were also looking at the impact of plastic on mesopelagic fish, such as lanternfish.[51][52] This group utilized a dedicated oceanographic research vessel, the 170 ft (52 m) long New Horizon.[53][54]
In 2012, Miriam C. Goldstein, Marci Rosenberg, and Lanna Cheng wrote:
Plastic pollution in the form of small particles (diameter less than 5 mm) — termed ‘microplastic’ — has been observed in many parts of the world ocean. They are known to interact with biota on the individual level, e.g. through ingestion, but their population-level impacts are largely unknown. One potential mechanism for microplastic-induced alteration of pelagic ecosystems is through the introduction of hard-substrate habitat to ecosystems where it is naturally rare. Here, we show that microplastic concentrations in the North Pacific Subtropical Gyre (NPSG) have increased by two orders of magnitude in the past four decades, and that this increase has released the pelagic insect Halobates sericeus from substrate limitation for oviposition. High concentrations of microplastic in the NPSG resulted in a positive correlation between H. sericeus and microplastic, and an overall increase in H. sericeus egg densities. Predation on H. sericeus eggs and recent hatchlings may facilitate the transfer of energy between pelagic- and substrate-associated assemblages. The dynamics of hard-substrate-associated organisms may be important to understanding the ecological impacts of oceanic microplastic pollution.[55]
The Goldstein et al. study compared changes in small plastic abundance between 1972-1987 and 1999-2010 by using historical samples from the Scripps Pelagic Invertebrate Collection and data from SEAPLEX, a NOAA Ship Okeanos Explorer cruise in 2010, information from the Algalita Marine Research Foundation as well as various published papers.[56]
At TEDxDelft2012,[57][58] Dutch Aerospace Engineering student Boyan Slat unveiled a concept for removing large amounts of marine debris from the five oceanic gyres. Calling his project The Ocean Cleanup, he proposed to use surface currents to let debris drift to specially designed arms and collection platforms. Operating costs would be minimal and the operation would be so efficient that it might even be profitable. The concept makes use of floating booms, that divert rather than catch the debris. This way bycatch would be avoided, although even the smallest particles would be extracted. According to Slat's calculations, a gyre could be cleaned up in five years' time, collecting at least 7.25 million tons of plastic across all gyres.[59] He also advocated "radical plastic pollution prevention methods" to prevent gyres from reforming.[59][60]
Method, a producer of household products, markets a dish soap whose container is made partly of recycled ocean plastic. The company sent crews to Hawaiian beaches to recover some of the debris that had washed up.[61]Artists such as Marina DeBris use trash from the garbage patch to create trashion, or clothes made out of trash. The main purpose is to educate people about the garbage patch.
The 2012 Algalita/5 Gyres Asia Pacific Expedition began in the Marshall Islands on 1 May, investigated the little-studied Western Pacific garbage patch, collecting samples for the 5 Gyres Institute, Algalita Marine Research Foundation and several other colleagues, including NOAA, SCRIPPS, IPRC and Woods Hole Oceanographic Institute. From 4 October – 9 November 2012, the Sea Education Association (SEA) conducted a research expedition to study plastic pollution in the North Pacific gyre. A similar research expedition was conducted by SEA in the North Atlantic Ocean in 2010. During the Plastics at SEA 2012 North Pacific Expedition, a total of 118 net tows were conducted and nearly 70,000 pieces of plastic were counted to estimate the density of plastics, map the distribution of plastics in the gyre, and examine the effects of plastic debris on marine life. [62]
On 11 April 2013, in order to create awareness, artist Maria Cristina Finucci founded The Garbage Patch State at UNESCO[63] –Paris in front of Director General Irina Bokova. It was the first of a series of events under the patronage of UNESCO and of the Italian Ministry of the Environment.[64] In 2015, The Ocean Cleanup project was a category winner in the Design Museum's 2015 Designs of the Year awards.[65] A fleet of 30 vessels, including a 32 metres (105 ft) mothership, took part in a month-long voyage to determine how much plastic is present using trawls and aerial surveys.[65]
In 2016, plans are in the concept stage to create floating Oceanscrapers, made from the plastic found in the Great Pacific garbage patch.[66] In June, The Ocean Cleanup project launched a prototype boom, nicknamed Boomy McBoomface, off the coast of the Netherlands in the North Sea, with the intention that if tests with the 100 meter prototype go well plans to develop a 100 kilometer long scaled up version that would then be deployed in the Pacific would go forward.[67]

15 Major Current Environmental Problems

1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.

2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides. Overpopulation is one of the crucial current environmental problem.
4. Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years.

5. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
6. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario.
7. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
8. Deforestation: Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial purpose.
9. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
10. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Antarctic. The CFC’s are banned in many industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem.

Global Waste on Pace to Triple by 2100

Why is Trash a Problem?

Trash is becoming a larger and larger problem for us and for the environment. As we continue to waste more and more, we use more natural resources and increase pollution in our world.

About 900 million trees are cut down each year to create raw materials for American paper and paper mills. The average American uses 18 tons of paper, 23 tons of wood, 16 tons of metal, and 32 tons of organic chemicals in one lifetime. The oil from an oil change in a car can end up in oceans, sewers, and landfills, contaminating millions of gallons of water. These and other facts show us that our world cannot continue to sustain this amount of waste. Conservation and recycling need to become more frequent actions. (Clean Air Council Waste Facts and Figures, 2006) 

What Happens to Our Trash?

America accounts for over one-third of the world's waste. Most of that trash ends up in landfills. In the United States, one ton of waste per person ends up in landfills each year. Also, about seventy percent of U.S. municipal waste is buried in landfills. The Fresh Kills landfill in New York City is one of the only man-made structures visible from space! (Clean Air Council Waste Facts and Figures, 2006)Much of our garbage also is dumped into the ocean. About ten percent of all the world's plastic waste ends up in the ocean. Due to ocean currents, most of this plastic gathers in the Pacific Ocean. It also greatly affects marine life. Over a million seabirds and 100 thousand marine mammals die every year from trying to eat these plastics which they mistake for food. (Marks and Howden, 2008)

Recycling and composting are other ways to deal with trash. Both recycling and composting can decrease the use of resources, the amount of pollution in the atmosphere, and the amount of trash which would end up in landfills or the ocean. Recycling can save trees, landfill space, water, energy, oil, and greatly reduce pollution. For example, recycling an aluminum soda can saves 96% of the energy used to make a can from ore, and also decreases by about 96% the amount of air and water pollution emitted from the production of cans from ore. And 1,500 aluminum cans are recycled every second in the U.S. (Clean Air Council Waste Facts and Figures, 2006)
Even though more than thirty percent of household wastes are compostable, most of these go to landfills. Composting can greatly reduce the volume of waste sent to landfills, reduce the amount of pollution created from landfills, and is also an inexpensive way of creating natural fertilizer for plants. Despite these advantages, composting is rarely done by most families. (Clean Air Council Waste Facts and Figures, 2006)
