Pollution in the Pacific Ocean

Pollution has become an ongoing problem throughout the Earth. From air pollution to waste pollution, the Earth is getting destroyed from the carelessness of others. More importantly, plastic is one of the leading problems of waste pollution, as it can take hundreds of years to break down, if at all. As the plastic industries grow, so does the amount of waste that is created, and that trash has to go somewhere. Many don't tend to think about where their trash […]

Campaign against Plastic Pollution

Plastic has become a necessity in man’s life all around the world. Plastics are in everything; your toothbrush, mechanical pencil, cell phone, milk jug, and even your face wash. This “versatile, lightweight, flexible, moisture-resistant, strong, and relatively inexpensive” substance has dire consequences on the ocean environment because it is extremely durable and non-biodegradable (Le Guern, 2018). Consequently, plastic is found floating around in our oceans for decades. Some countries are enforcing taxes, laws, and bans on microplastics (such as plastic […]

Plastic Pollution in Tho Ocean: Facts and Information

To many, the ocean may just serve as a place for water recreation and fishing. However, without the ocean, the Earth would not have the air we breathe. The ocean produces over half the world’s oxygen and absorbs fifty times more carbon than the atmosphere. Covering more than 70 percent of the earth’s surface we truly have only one “World Ocean”. Home to 97 percent of the planet’s water supply saltwater moves from one part of the ocean to another […]

The UN Environment Assembly passed a resolution in Dec. 2017 to eliminate plastic pollution in […]

Plastic Pollution of Earth’s Oceans

Introduction Approximately 300 million tons of plastic is produced every year (Cressey 2016). It's disposable, yet long-lasting nature makes it critical to pose the question “where does all this plastic end up?” A large quantity of the plastic produced eventually ends up floating on the surface of the ocean- some even reach the seafood humans eat (Rochman, 2016). Plastic is a cheap, versatile, disposable material that does not degrade easily, making it a perfect candidate for a variety of uses […]

The Negative Effect of Single Use Plastic

One of the largest producers of plastic wastes in Asia is the Philippines. According to PhilStar Global (2018), about 79 percent of branded plastic residual wastes came from food packaging, followed by household and personal care products with 12 and eight percent, respectively. One of the solutions that the researchers have in mind to minimize producing plastic waste is the banning of single-use plastic. The researchers envision their campus free from single-use plastic and free from its harmful effects on […]

Autoethnography Example: a Personal Journey of Beach Cleanups Across Generations

Ocean Trash: 5.25 Trillion Pieces and Counting, but Big Questions Remain

Big questions remain. The numbers add up to trouble for the oceans, wildlife, and us, but scientists are struggling to understand how. The numbers are staggering: There are 5.25 trillion pieces of plastic debris in the ocean. Of that mass, 269,000 tons float on the surface, while some four billion plastic microfibers per square kilometer litter the deep sea.

The numbers are staggering : There are 5.25 trillion pieces of plastic debris in the ocean. Of that mass, 269,000 tons float on the surface, while some four billion plastic microfibers per square kilometer litter the deep sea. Scientists call these statistics the "wow factor" of ocean trash. The tallies, published last year in three separate scientific papers, are useful in red-flagging the scope of the problem for the public. But beyond the shock value, just how does adding up those rice-size fragments of plastic help solve the problem? Although scientists have known for decades about the accumulating mass of ocean debris and its deadly consequences for seabirds , fish, and marine animals, the science of sea trash is young and full of as-yet-unsolved mysteries. Almost nothing was known about the amount of plastic in remote regions of the Southern Hemisphere, for example, until last year because few had ever traveled there to collect samples. "The first piece is to understand where it is," says Kara Lavender Law, an oceanographer at the Sea Education Association in Woods Hole, Massachusetts. Indeed, until scientists learn more about where ocean trash is, how densely plastic accumulates in different ocean ecosystems , and how it degrades, they can't really calculate the damage it's causing. There are still big, basic questions: As it degrades, do plastic toxins seep into the marine environment? If so, how and in what amounts? And though scientists know a great deal about the damage to marine life caused by large pieces of plastic, the potential harm caused by microplastics is less clear. What effect do they have on fish that consume them? "The greater the concentration , the greater the potential risk for exposure," says Richard Thompson, a biologist at Plymouth University in England, whose study released last month identified microfibers widely disseminated throughout the deep ocean. "If we are missing a major sink where there are major concentrations of plastic, we might not be learning how harmful plastics are." The most recent counts add significantly to the knowledge base, yet even those big numbers are a fraction of the plastic that flows into the oceans every year. Where's the rest of it? It's another mystery. We are dealing with pieces from hundreds of meters down to microns in size," Thompson says. "It is incredibly challenging to monitor." Ocean trash is counted in three ways: through beach surveys, computer models based on samples collected at sea, and estimates of the amount of trash entering the oceans. The most recent counts involved computer modeling based on samples taken at sea. The models may not account for all of the trash, scientists say; nonetheless, the new numbers are helping address some of the questions. The process of collecting and counting is meticulous , time-consuming work. It took Marcus Eriksen, co-founder of the 5 Gyres Institute, a nonprofit ocean advocacy group, more than four years, using samples gathered from 24 survey trips, to come up with his estimate that 5.25 trillion pieces of debris float on the surface. In the course of his expeditions, Eriksen collected everything from plastic candy wrappers to giant balls of fish netting. One massive ball of netting, found midway across the Pacific, contained 89 different kinds of net and line, all wrapped around a tiny, two-inch-high teddy bear wearing a sorcerer's cap at the center. He says his research has helped fill in the outlines of the life cycle of ocean plastic. It tends to collect in the world's five large gyres, which are large systems of spiraling currents. Then, as the plastic degrades into fragments, it falls into deeper water, where currents carry it to remote parts of the globe. "These fragments are anywhere on the planet at this point," he says. "We're finding them everywhere." Eriksen's findings agree with those of a Spanish scientist, Andres Cozar Cabañas, a researcher at the University of Cadiz, in Spain, who published the first global map of floating ocean debris last July. Their estimates are strikingly similar. "We now have two estimates of what is floating, and they are almost identical," says Lavender Law. "They used different data sets and different methodology and came up with the same number. That gives us confidence we're in the right ballpark." Another way of coming up with the numbers is to make crude guesses based on manufacturing statistics. Says Jenna Jambeck, a University of Georgia environmental engineer who is completing a worldwide calculation of garbage collected in coastal countries: "If you have 200 million tons produced every year, researchers will arbitrarily estimate that 10 percent goes into the oceans." Sort Out the Rubbish It's not too difficult to surmise why so much plastic ends up in the ocean. The Plastic Disclosure Project, a project run by Hong Kong-based advocacy group Ocean Recovery Alliance, estimates that 33 percent of plastic manufactured worldwide is used once, then discarded. To compound matters, 85 percent of the world's plastic is not recycled. Despite the magnitude of the numbers, Peter Ryan, a zoologist at the University of Cape Town, South Africa, who is writing a book tracing the evolution of marine debris research, says the problem can be solved. "Marine debris, unlike global warming, should be an easy thing to deal with," he says. "We have to sort out what to do with our rubbish." Ryan began tracking debris 30 years ago, after a colleague suggested he should study seabirds that were eating floating plastic pellets, then commonly used in manufacturing and found in harbors and other waterways. Improvements to shipping reduced pellet spillage. "If you go to the beach today, you struggle to find one," he says. "We can show that in every study that looks at the North Atlantic that the amount of pellets [ ingested by] seabirds has decreased over the last two decades." But gains on that front have given way to losses in others, as microplastics have become more prevalent. Emily Penn skippers the 72-foot, steel-hulled Sea Dragon, which carries scientists, including Eriksen and Jambeck, on sea trash sampling surveys. She expertly handles the nets trawled behind the vessel and knows what to expect. Nevertheless, she is still surprised and dismayed by the volume of trash. "The thing that shocks me every time is the fact that the ocean looks like it is clear blue water," she says. "And then ... we pull out that sock at the end of the net and find it's full of thousands of fragments of plastic." Originally published by nationalgeographic.com on January 11, 2015.

Ocean plastic pollution an overview: data and statistics

09 May 2022

https://oceanliteracy.unesco.org/plastic-pollution-ocean/

Plastic is one of the most enduring materials man has created. Nowadays, we all know that it can take hundreds of years for plastic to degrade, and research is showing that it is possible that it does not even fully degrade, but becomes what we call microplastic .

Microplastics are tiny particles of plastic that can be eaten by marine animals and end up in their bodies and tissues, entering the food chain and leading to disastrous consequences for the health of our planet and all its inhabitants.

Even if human beings are becoming more and more aware of the hazards this material poses to life, the presence of plastic in our ocean is continually increasing, and plastic pollution is still one of the main causes of marine species extinction , health problems for human beings and animals alike, and the destruction of our ecosystems.

In this article, we will look at ocean plastic pollution and lay out the data and statistics you need to understand the daunting issue we are facing. Most importantly, we will also look at what we can do as individuals and as part of our society to prevent plastic pollution and save our planet.

Let’s start!

Plastic Pollution in the Ocean: Where does it come from?

It is clear that plastic pollution is one of the most pressing environmental issues we are currently facing, but how did it come to be? Moreover, where does all the plastic in the ocean come from?

Plastics produced from fossil fuels are just over a century old , but they revolutionized our life completely. It allowed the invention of many life-saving devices and the implementation of new technologies that changed the course of history.

However, the great advantages plastic offered led to a throwaway trend that made us discover plastic’s dark side: the threat it poses to our environment and life.

The majority of plastic pollution in the ocean is caused by littering : we buy or use disposable plastic items (food wrappings, plastic bags, razors, bottles, etc.) and do not dispose of them properly, which cause them to end up in the waterways and eventually in the ocean.

Yet, not all-plastic waste in the ocean is an effect of littering: many plastics and microplastics are the product of improper manufacturing processes and about 20% of the ocean’s plastic pollution comes from industrial fishing.

Plastic Pollution: Key Facts

• Plastic waste makes up 80% of all marine pollution and around 8 to 10 million metric tons of plastic end up in the ocean each year.
• Research states that, by 2050, plastic will likely outweigh all fish in the sea.
• In the last ten years, we have produced more plastic products than in the previous century.
• The EPA (Environmental Protection Agency) has stated that basically 100% of all plastics human beings have ever created are still in existence.
• Plastic generally takes between 500-1000 years to degrade. Even then, it becomes microplastics, without fully degrading.
• Currently, there are about 50-75 trillion pieces of plastic and microplastics in the ocean.
• This plastic either breaks down into microplastic particles (see below), or floats around and ends up forming garbage patches.

Garbage Patches in the Ocean

Most of the plastic we find in the ocean comes from land: it flows downstream through rivers all the way to the sea. At first, it may stay in coastal waters, but it can soon be picked up by rotating ocean currents , called gyres, and transported literally anywhere in the world.

According to National Geographic, scientists found plastic coming from Russia, the United States, Europe, South America, Japan, and China on Henderson Island , an uninhabited isolated atoll halfway between Chile and New Zealand.

Usually, marine plastic debris groups up in what we call garbage patches, plastic accumulation areas, in the center of the ocean’s gyres. The biggest is the Great Pacific garbage patch , located between Hawaii and California.

Consequences

Today, plastic production and use is still at its highest, but the data on recycling are not at all promising: only about 10% of the plastic we produce is currently being recycled . The rest is either incinerated, causing air pollution, or it ends up in our oceans and environment.

Harm to Wildlife

Plastic pollution in the ocean has a devastating impact on marine life and ecosystems. The most obvious one being the damage plastic items cause to animals when they come into contact with or ingest them, which include suffocation, entanglement, laceration, infections and internal injuries.

17% of the species affected by the presence of plastic in the ocean are on the International Union for Conservation of Nature Red List of Threatened Species.

Yet, there are more problems related to plastic: floating plastic items can help transport invasive species, which leads to threats for marine ecosystems , biodiversity and the food web.

Harm to Human Beings

As we explained above, microplastics have now become part of the food chain and have been found everywhere: in drinking water, salt, beer and in the soil where we grow our vegetables.

Plastic materials are carcinogenic and can affect the body’s endocrine system, causing developmental, neurological, reproductive and immune disorders. Another health hazard is given by toxic contaminants that often accumulate on plastic’s surface, and are then transferred to humans through the consumption of seafood.

Climate Change

Plastic pollution and climate change are two sides of the same coin : plastic production, as it is created from fossil fuels, highly contributes to the climate crisis.

Moreover, as we already mentioned, when plastic waste is incinerated, it releases carbon dioxide and methane into the atmosphere, increasing emissions and worsening global warming.

Economic effects

According to research, the yearly economic costs of plastic in the ocean are estimated to be between $6-19bn USD. These costs are given by its impact on tourism, fisheries and aquaculture, and (governmental) cleanups.

Images of Plastic Pollution in the Ocean

Here, we have decided to show you some recent images of plastic pollution in the ocean.

This will help you comprehend the magnitude of the threat that plastic pollution in the ocean poses to our planet and life, as we know it, and hopefully help you develop a deeper awareness of what is going on.

Why it is Vital to Prevent Plastic Pollution

Plastic pollution is undoubtedly an issue that requires worldwide cooperation. Its consequences affect the whole planet and its inhabitants: it threatens ocean health , the health of marine species, food safety and quality, human health , coastal tourism, and contributes to climate change.

Reducing the presence of plastic in our oceans will not only allow us to save marine species and ecosystems, but will improve our overall health and that of the environment in general, helping us fight climate change and working towards a more sustainable future .

How to Stop Plastic Pollution in the Ocean

It is quite hard to retrieve plastic from the ocean once it has entered it. New technologies allow us to catch larger marine debris, but small plastic items and microplastics are virtually impossible to reach, especially when they are deep in the ocean.

Therefore, many scientists and conservationists have declared that the best solution is to prevent plastic waste from entering rivers and seas in the first place.

This could be accomplished with the improvement of our waste management systems and the implementation of recycling . In addition, it is essential to reconsider the design and usage of disposable packaging , and the reduction in manufacturing of unnecessary single-use plastics.

What Can We Do

There are many ways to keep plastic out of the ocean ! Here are some strategies you can adopt and share with your community:

• Reduce plastic use Think about all the plastic items you use in your daily life. Can you even count them all? Being more aware of the way you use plastic is a great starting point to reduce plastic waste.

We know, habits are hard to change, but even a small individual commitment can make a difference especially when talking about the single-use plastics we mentioned earlier which, according to data from the European Parliament, are responsible for 49% of all marine pollution.

Here are some new habits you can take inspiration from:

• Swap plastic bags for reusable ones, made of cloth or fiber.
• Reduce the use of disposable plastic cups, plates, cutlery and bottles. For example, bring your own reusable bottle to work and a reusable coffee cup for your morning take-away!)
• Buy food and cleaning products in bulk to avoid useless plastic wrappings. Nowadays, there are plenty of options to choose from, and many supermarkets let you fill your own jars/bags.
• Choose metal or glass food containers and storage options instead of plastic ones.
• Avoid buying and using cosmetics that contain plastic microspheres or microbeads.
• Participate in (or organize!) a cleanup

If you live by a sea or river, you can volunteer to pick up litter in your local community, thus remove plastics from the waterways and preventing them from getting to the ocean in the first place. There are many organizations you can join, or simply do it on the weekend with your friends and family. Every little helps!

• Support the right legislation

Of course, it is essential to change our individual behaviors and habits, but unfortunately, this is not sufficient to prevent and stop ocean plastic pollution. It is also essential that you support legislation that aims at reducing the use and production of plastic, improve recycling facilities and better manage waste in general.

• Support research and organizations

One of the main weapons we can use to stop ocean pollution is research. By deepening our knowledge of the effects of the issue, we can start implementing better policies for all.

There are many NGOs and non-profit that rely on donations to develop their projects and research for reducing and eliminating plastic from the ocean. Here are some examples:

• Oceanic Society
• Plastic Pollution Coalition
• Plastic Soup Foundation

Sylvia Earle, marine biologist, said: “It is the worst of times but it is the best of times because we still have a chance.” So, let us make the best of this chance; we can all make choices to protect our planet, it is not too late!

Ocean pollution is widespread, worsening, and poses a clear and present danger to human health and wellbeing. But the extent of this danger has not been widely comprehended – until now. Our recent study provides the first comprehensive assessment of the impacts of ocean pollution on human health.

Ocean pollution is a complex mixture of toxic metals, plastics, manufactured chemicals, petroleum, urban and industrial wastes, pesticides, fertilisers, pharmaceutical chemicals, agricultural runoff, and sewage. More than 80% arises from land-based sources and it reaches the oceans through rivers, runoff, deposition from the atmosphere – where airborne pollutants are washed into the ocean by rain and snow – and direct dumping, such as pollution from waste water treatment plants and discarded waste. Ocean pollution is heaviest near the coasts and most highly concentrated along the coastlines of low-income and middle-income countries.

Ocean pollution can also be found far beyond national jurisdictions in the open oceans, the deepest oceanic trenches, and on the shores of remote islands. Ocean pollution knows no borders.

The most hazardous ocean pollution

Plastic waste is the most visible component of ocean pollution. More than ten million tonnes of plastic enter the seas every year. The majority of this breaks down into microplastic particles and accumulates in coastal and deep-sea sediments.

Some large pieces float in the water for decades ending up as massive concentrations where currents converge and circulate. The Pacific Ocean’s so called “garbage patch” is a well-known example.

Microplastics contain multiple toxic chemicals that are added to plastics to make them flexible, colourful, waterproof or flame-resistant. These include carcinogens, neurotoxins, and endocrine disruptors – chemicals that interfere with hormones, and can cause cancer, birth defects, and reduced fertility.

These chemical-laden particles enter the food chain and accumulate in fish and shellfish. When humans eat seafood contaminated with these materials, we ingest millions of microplastic particles and the many chemicals they carry. Though there is still debate on the harm to humans from microplastics, exposure to these chemicals increases the risk of all the diseases that they cause. Virtually all of us have microplastics in our bodies today.

Mercury is widespread in the oceans, and the major culprit is coal burning in homes and industry . All coal contains mercury, and when it burns, mercury vaporises, enters the atmosphere, and eventually washes into the sea. Gold mining is another source , as mercury is used to dissolve gold from the ore.

Mercury can accumulate to high levels in predatory fish such as tuna and swordfish, which are in turn eaten by us. Contaminated fish can be especially dangerous if eaten by expectant mothers. Exposure of mercury to infants in the womb can damage developing brains, reducing IQ and increasing risks for autism, ADHD, and other learning disorders. Adult mercury exposure increases risks for heart disease and dementia .

Petroleum pollutants from oil spills threaten the marine microorganisms that produce much of the Earth’s oxygen by reducing their capacity for photosynthesis. These beneficial microorganisms use solar energy to convert atmospheric CO₂ into oxygen and are also affected by organic pollutants and other chemicals . When there is a major oil spill, the impact can be huge.

Coastal pollution from industrial waste, agricultural runoff, pesticides, and sewage increases the frequency of harmful algal blooms, known as red tides, brown tides, and green tides. These blooms produce powerful toxins like ciguatera and domoic acid that accumulate in fish and shellfish. When ingested, these toxins can cause dementia, amnesia, paralysis, and even rapid death. When inhaled, they can cause asthma.

Dangerous microorganisms result from a combination of coastal pollution and warming seas, which encourages their spread. Harmful bacteria such as the vibrio species – found in warmer waters and responsible for vibriosis , a potentially fatal illness – are now appearing further north and causing life-threatening infections. There’s a high risk that cholera, caused by vibrio cholerae , could spread to new, previously unaffected areas.

And the health impacts of ocean pollution fall disproportionately on indigenous peoples, coastal communities and vulnerable populations in the Global South , underlining the planetary scale of this environmental injustice.

Political will and scientific evidence

While the findings in this report are alarming, the good news is that ocean pollution, as with all forms of pollution, can be controlled and prevented. Bans on single-use plastics and better waste sorting can curb pollution at its source, especially plastic waste, both on land and at sea.

Wise governments have curbed other forms of pollution by deploying control strategies based on law, policy, technology, and targeted enforcement. The US, for example, has reduced air pollution by 70% since the passage of the Clean Air Act in 1970. They have saved thousands of lives. They have proven highly cost-effective .

Countries around the world are now applying these same tools to control ocean pollution. Boston Harbour in Massachusetts and Victoria Harbour in Hong Kong have been cleaned. Estuaries from Chesapeake Bay in the US to the Seto Inland Sea in Japan have been rejuvenated. Some coral reefs have been restored, such as those in American Samoa , where vigilance, protection and quick response have happened in relation to various pollution threats.

These successes have boosted economies, increased tourism, restored fisheries, and improved health. They demonstrate that broad control of ocean pollution is feasible and their benefits will last for centuries. Our study offers some clear recommendations for preventing and controlling ocean pollution, including transitioning to cleaner energy, developing affordable alternatives to fossil fuel-based plastics, reducing human, agricultural and industrial discharges, and expanding Marine Protected Areas .

Protecting the planet is a global concern and our collective responsibility. Leaders who recognise the gravity of ocean pollution, acknowledge its growing dangers, engage civil society, and take bold, evidence-based action to stop pollution at source will be essential for preventing ocean pollution and safeguarding our own health.

Scientific evidence sheds light on the extent, source and type of litter in the oceans, as well as on the limited efforts to clean it up so far. As we rely on healthy oceans for our future, it’s time to act.

Well into 2021, most countries around the world continue to battle with the impacts of the COVID-19 pandemic. On 11–13 June, the G7 leading democracies (Canada, France, Germany, Italy, Japan, United Kingdom and United States, plus the European Union) are set to meet in Cornwall, United Kingdom, to help win the fight against the pandemic and discuss how to build a more prosperous future for all. A lot has been said about the need to shape sound recovery policies centred on health and sustainability and collaborations have emerged over the course of the past year to inform decision makers on what, and how, to innovate in order to bounce forward sustainably . The G7 countries have a unique opportunity to listen to science and lead the efforts of the global community in pursuit of innovative policies that can build a more sustainable development trajectory across the globe.

Against this backdrop, the International Programme on the State of the Ocean ( IPSO ) virtually convened marine scientists from different countries to work out a plan of action to ensure a sustainable ocean future. The scientists wrote a statement known as ‘Seven asks for the G7’ to request that priority is given to the protection of the oceans in the pandemic recovery plans that are to be discussed at the summit in Cornwall.

Mounting scientific evidence of the severe impacts of human actions on the ocean environment, and the associated societal and economic implications of those impacts, leaves everyone with no doubt about the risk of inaction. Politicians around the world have to step up efforts now.

One of the seven ‘asks’ from the IPSO convening is about ocean pollution. Although public awareness of the problem has grown rapidly over the past years, with several reports in the media , policy makers need comprehensive and reliable data about the actual magnitude and nature of the problem in order to intervene. In an article by Morales-Caselles and colleagues in Nature Sustainability , the authors conduct a substantial effort to harmonize worldwide aquatic litter inventories. The harmonized data show that ocean litter globally is dominated by plastics from take-out food, followed by fishing gear — a stark sign of how human activities, and in particular our food habits, impact the oceans. The experts are also able to show how litter is trapped in near-shore areas with land-sourced plastic reaching the open ocean mostly as small fragments. In another article by González-Fernández and co-authors, using a unique database of riverine floating macrolitter across Europe, the authors estimate that 307–925 million litter items — 82% of which is plastic — are transferred from Europe to the ocean annually. They also find that a major portion of the total litter loading is transferred through small rivers, streams and coastal run-off. This result clearly urges countries in Europe to increase efforts to keep rivers pollution-free. Overall, both papers suggest that waste management alone won’t be enough — consumption habits do play a key role in the fight against ocean litter.

Innovative solutions — to prevent, monitor and clean (PMC) marine litter — are necessary to restore healthy oceans and maintain their well-being over time. And again, little is known about how many of these solutions have been developed and implemented, and to what extent they have been effective as information is scattered across platforms and not easily accessible. In a global analysis by Bellou and colleagues, also in Nature Sustainability , the researchers identify 177 PMC solutions and find that 106 of them address monitoring; 33 address prevention (mostly via wastewater treatment); only 30 address cleaning. They also find an inconsistent use of litter size terms across the various developers, which required a harmonization effort to assess the type of litter addressed — results show that 137 of the solutions targeted macrolitter. Overall, only few solutions reached technical readiness and no solution was validated for efficiency and environmental impacts.

Policy makers alongside industry innovators, non-governmental organizations and citizens have a long way to go to address and reverse the trend of ocean pollution. The G7 summit could set the agenda for change — we expect that those influencing players will not shy away from the scientists’ call for action on the oceans.

Tackling marine pollution: Individual action, key to ocean restoration

Facebook Twitter Print Email

On Monday, thousands of people gathered at Altice Arena in Lisbon, Portugal, for the first day of the long-awaited UN Ocean Conference. Riding on the global momentum generated by the event, experts are pushing for a new international commitment to combat pollution, including at sea.

According to the UN Environment Programme ( UNEP ), the amount of marine litter and plastic waste, has been growing rapidly . And without meaningful action, emissions of plastics into aquatic ecosystems, are projected to nearly triple by 2040.

"I want to share the magic and the power of the ocean."Newly designated @ UNESCO Champion for the Ocean and Youth and world-famous Brazilian surfer, Maya Gabeira, reminds us at the #UNOceanConference, that collectively we can #SaveOurOcean. #OceanDecade pic.twitter.com/pL1ashuf48 UNESCO 🏛️ #Education #Sciences #Culture 🇺🇳😷 UNESCO

Following the high-level plenary , a panel of experts met to discuss the marine pollution issue, focusing on finding solutions.

Urgency of pollution crisis

Pollution cuts across several sectors and is strongly interconnected with the other planetary crises of climate change and biodiversity loss. Combatting marine pollution is a global challenge, that needs a global approach if it’s to be mitigated, experts remarked.

“Sea-based pollution, including discharges and spills from vessels and the presence of abandoned, lost, or otherwise discarded fishing gear, continues to be of concern, with plastics and microplastics from numerous sources, untreated wastewater and nutrient run-off still polluting the oceans”, said a statement published by organizers of the event. 

Speaking in Lisbon, Janis Searles Jones, Chief Executive Officer at the Ocean Conservancy, in Portland, Oregon, stressed that “life below water is essential to life above water”, and underlined the urgency of reducing single-use plastic, and faster action.

‘Scream loud’: ban single-use plastic

On the sidelines of the Conference, the UN educational and scientific agency (UNESCO) named giant-wave surfer and two-time Guinness World Record holder, Maya Gabeira, Champion of the Ocean and Youth.

Speaking at an event in the SDG Media Zone – “Empowering youth for the Ocean we need” - the Brazilian athlete shared that even in her most remote surfing spot - which she can only reach after travelling for 55 hours - she finds plastic surrounding her when she is catching the waves.

“It is very sad when you are surfing and the tide turns and all that plastic moves into you, and you are trying to make space, or put whatever you can in your pockets to bring to a recycling trash, but we know that’s not even a dent, and that is not the solution.”

Speaking to UN News , Ms. Gabeira reiterated the importance of educating herself and of learning ways of creating less of a footprint – not just by using less plastic, but also by using her platform to “scream as loud” as possible, to drive change, adding that every single one of us, can make a difference.

At the event, UNESCO’s Director-General Audrey Azoulay reiterated the commitment to integrate ocean education into national curricula of all Member States by 2025, underlining the importance of ocean literacy .

Changes in consumption patterns needed

According to UNEP’s most recent data , and despite current initiatives and efforts, the amount of plastic in the ocean is now estimated to be 75-199 million tons.

Population increases, changes in consumption patterns and other types of behaviour, and greater market accessibility lead to higher waste generation, while the resources and technical capacity for sound waste management are limited in some countries which decide they have more pressing public spending needs.

All these pollution challenges require national and regional cooperation and knowledge-sharing among diverse stakeholders, experts warned.

For fashion designer and UNESCO Goodwill Ambassador, Oskar Metsavaht, fashion is also a way of changing attitudes and behaviour, just like any other art form, such as cinema and music, he told UN News.

Youth is essential

A major concern among environmentalists is what happens during the breakdown of plastics in the ocean, chiefly in the form of microplastics – which are small pieces of plastic less than 5 mm in diameter - and chemical additives, which are known to be toxic and hazardous to human and wildlife health, as well as ecosystems.

“Youth [needs] not only to question the system, but changing their behaviours of consumerism, and using nature, conservancy, and sustainable development, oceans and forests, to be inspirational”, the creator of the lifestyle brand Osklen added.

“New fabrics, new materials, and new technologies need to be implemented in a sustainable way – we still need to find a solution to avoid the microplastics in fashion”, Mr. Metsavaht concluded.

One of the expected outcomes of the Conference and of the United Nations Decade of Ocean Science for Sustainable Development is to identify science-based and innovative actions to overcome challenges in reaching SDG Goal 14 including in the preventing, reducing, and elimination of marine plastic litter.

During the week, UN News will bring you daily coverage on the Conference as well as interviews, podcasts, and features, which you can access  here .

Sanctuaries resource collection: Marine debris

Each year, billions of pounds of trash and other pollutants enter the ocean. Where does this pollution come from? Where does it go? Some of the debris ends up on our beaches, washed in with the waves and tides. Some debris sinks, some is eaten by marine animals that mistake it for food, and some accumulates in ocean gyres . Other forms of pollution that impact the health of the ocean come from sources like oil spills or from accumulation of many dispersed sources, such as fertilizer from our yards.

Litter such as plastic detergent bottles, crates, buoys, combs, and water bottles blanket Kanapou Bay, on the Island of Kaho’olawe in Hawaii. This region is a hot-spot for marine debris accumulation. (Image credit: NOAA)

Where does pollution come from?

The majority of pollutants that make their way into the ocean come from human activities along the coastlines and far inland. One of the biggest sources of pollution is nonpoint source pollution , which occurs as a result of runoff . Nonpoint source pollution can come from many sources, like septic tanks, vehicles, farms, livestock ranches, and timber harvest areas. Pollution that comes from a single source, like an oil or chemical spill, is known as point source pollution . Point source pollution events often have large impacts, but fortunately, they occur less often. Discharge from faulty or damaged factories or water treatment systems is also considered point source pollution.

Per- and polyfluoroalkyl substances (PFAS) are chemicals created by humans that are notorious for being resistant to biodegradation and have been found in ground, surface, and drinking water. Makayla Neldner, a 2022 Hollings scholar, spent her summer internship at NOAA’s Hollings Marine Lab in Charleston, South Carolina, researching how two PFAS compounds affected the life cycle of larval grass shrimp ( Palaemon pugio ).

Nutrients and algal blooms: Too much of a good thing?

Sometimes it is not the type of material, but its concentration that determines whether a substance is a pollutant. For example, the nutrients nitrogen and phosphorus are essential elements for plant growth. However, if they are too abundant in a body of water, they can stimulate an overgrowth of algae, triggering an event called an algal bloom . Harmful algal blooms (HABs) , also known as “ red tides ,” grow rapidly and produce toxic effects that can affect marine life and sometimes even humans. Excess nutrients entering a body of water, either through natural or human activities, can also result in hypoxia or dead zones . When large amounts of algae sink and decompose in the water, the decomposition process consumes oxygen and depletes the supply available to healthy marine life. Many of the marine species that live in these areas either die or, if they are mobile (such as fish), leave the area.

Using ecological forecasting , NOAA is able to predict changes in ecosystems in response to HABs and other environmental drivers. These forecasts provide information about how people, economies, and communities may be affected. For example, the Harmful Algal Bloom Monitoring System developed by NOAA’s National Centers for Coastal Ocean Science provides information to the public and local authorities to help decide whether beaches need to be closed temporarily to protect public health.

Researchers at the St. Jones Reserve, a component of the Delaware National Estuarine Research Reserve, observed trash in songbird nests around the reserve’s visitor center. Hollings scholar Eleanor Meng studied whether this trash occurred more frequently in nests near the visitor center compared to nests further away.

Marine debris

Marine debris is a persistent pollution problem that reaches throughout the entire ocean and Great Lakes. Our ocean and waterways are polluted with a wide variety of marine debris, ranging from tiny microplastics , smaller than 5 mm, to derelict fishing gear and abandoned vessels. Worldwide, hundreds of marine species have been negatively impacted by marine debris, which can harm or kill an animal when it is ingested or they become entangled, and can threaten the habitats they depend on. Marine debris can also interfere with navigation safety and potentially pose a threat to human health.

All marine debris comes from people with a majority of it originating on land and entering the ocean and Great Lakes through littering, poor waste management practices, storm water discharge, and extreme natural events such as tsunamis and hurricanes. Some debris, such as derelict fishing gear , can also come from ocean-based sources. This lost or abandoned gear is a major problem because it can continue to capture and kill wildlife, damage sensitive habitats, and even compete with and damage active fishing gear.

Local, national, and international efforts are needed to address this environmental problem. The Save our Seas Act of 2018 amends and reauthorizes the Marine Debris Act to promote international action, authorize cleanup and response actions, and increase coordination among federal agencies on this topic.

Garbage patches: What and where are they?

Garbage patches are large areas of the ocean where trash, fishing gear, and other marine debris collects. The term “garbage patch” is a misleading nickname, making many believe that garbage patches are "islands of trash" that are visible from afar. These areas are actually made up of debris ranging in size, from microplastics to large bundles of derelict fishing gear.

These patches are formed by large, rotating ocean currents called gyres that pull debris into one location, often to the gyre’s center. There are five gyres in the ocean : one in the Indian Ocean, two in the Atlantic Ocean, and two in the Pacific Ocean. Garbage patches of varying sizes are located in each gyre. Due to winds and currents, garbage patches are constantly changing size and shape. The debris making up the garbage patches can be found from the surface of the ocean all the way to the ocean floor .

A group of teens from Mystic Aquarium received funding from NOAA and the North American Association for Environmental Education to lead an action project in their local community. The team chose to work with a non-profit organization to implement a project that focused on raising awareness on plastic pollution and recycling a common type of plastic used on boats.

The impact of marine pollution on seafood

Heavy metals and other contaminants can accumulate in seafood, making it harmful for humans to consume. Microplastics can be ingested by fish and other species that filter their food out of the water. With more than one-third of the shellfish-growing waters of the United States adversely affected by coastal pollution, it’s important for NOAA and it’s partners to study the impacts of microplastics and harmful contaminants in seafood. There is ongoing research around the country focusing on the potential risk to wildlife and humans from debris exposure and ingestion. NOAA monitors seafood contamination and provides safety tips through the Sustainable Seafood portal .

The B’more Conscious environmental fun festival at the National Aquarium focused on blue crab populations in Baltimore, plastic pollution and microplastics, eutrophication and food waste, and the urbanization of Baltimore City. 

EDUCATION CONNECTION

Whether humans live near the coasts or far inland, they are a part of the problem — and the solution — to ocean pollution. Through this collection of resources and information, students can be informed of the types of pollution harming our ocean, and learn about actions they can take to prevent further pollution no matter where they live. The NOAA Marine Debris Program provides many educational resources for educators, students, families, and adults to help better understand this global issue.

Ocean Pollution: The Dirty Facts

We’re drowning marine ecosystems in trash, noise, oil, and carbon emissions.

Paulo Oliveira/Alamy

• Share this page block

Covering more than 70 percent of our planet, oceans are among the earth’s most valuable natural resources. They govern the weather, clean the air, help feed the world, and provide a living for millions. They also are home to most of the life on earth, from microscopic algae to the blue whale, the largest animal on the planet. Yet we’re bombarding them with pollution. By their very nature—with all streams flowing to rivers, and all rivers leading to the sea—the oceans are the end point for so much of the pollution we produce on land, however far from the coasts we may be. And from dangerous carbon emissions and choking plastic to leaking oil and constant noise, the types of ocean pollution that humans generate are vast. As a result, collectively, our impact on the seas is degrading their health at an alarming rate. Here are some ocean pollution facts that everyone on our blue planet ought to know.

Ocean acidification

When we burn fossil fuels, we don’t pollute just the air but the oceans too. Indeed, today’s seas absorb as much as a quarter of all man-made carbon emissions , which changes the pH of surface waters and leads to acidification (pH is a measure of how acidic or basic water is). This problem is rapidly worsening—oceans are now acidifying faster than they have in some 300 million years. In absorbing so much of the carbon emissions from the atmosphere, the pH level of the ocean surface has increased an estimated 30 percent since the start of the industrial revolution 200 years ago. If greenhouse gas emissions continue to increase, the surface waters of the ocean could be nearly 150 percent more acidic by the end of the century.

Oregon State University

So what happens when the ocean’s chemistry is knocked out of whack? Marine ecosystems—and the coastal economies that depend on them—go out of whack too. Take reefs and shellfish, for starters. To build their shells and skeletons, creatures like mussels, clams, coral, and oysters require calcium carbonate (the same compound found in chalk and limestone). But the ocean’s carbonate levels go down when acidity levels rise, threatening the survival of these animals. Bivalves are at the bottom of the food chain, so these effects ripple up to many fish, seabirds, and marine mammals. More-acidic waters also contribute to the bleaching of coral reefs and make it harder for some types of fish to sense predators and for others to hunt prey .

Meanwhile, ocean acidification threatens us land dwellers too. The billion-dollar American shellfish industry is the economic backbone of myriad coastal communities , from Louisiana to Maryland to Maine . In the Pacific Northwest, the shellfish that are vulnerable to ocean acidification make up more than 60 percent of the fishery revenue. In total, the U.S. shellfish industry could lose more than $400 million annually by 2100 due to impacts of ocean acidification.

Trash in the ocean

The majority of the garbage that enters the ocean each year is plastic—and here to stay. That’s because unlike other trash, the single-use plastic bags, water bottles, drinking straws, and yogurt containers , totalling some eight million metric tons of the plastic waste we toss (instead of recycling), won’t biodegrade. Instead, they can persist in the environment for a millennium, polluting our beaches , entangling marine life, and getting ingested by fish, whales, turtles, and seabirds.

The most infamous example of marine debris is the Great Pacific Garbage Patch. But these patches (which are more like " soups ") represent only a fraction of the trash in our oceans. In fact, plastic debris has been found at the bottom of the deepest ocean trench.

Where does all this debris originate? While some is dumped directly into the seas, 80 percent of marine litter makes its way there gradually from land-based sources―including those far inland―via storm drains, sewers , and other routes, according to the National Oceanic and Atmospheric Administration (NOAA). Oil from boats, airplanes, cars, trucks, and even lawn mowers is contributing to water pollution circulating in ocean waters. (An excellent reason for why we should all reduce plastic pollution , no matter where we live.) Chemical discharges from factories, raw sewage overflow from water treatment systems, and stormwater and agricultural runoff add other forms of marine-poisoning pollutants to the toxic brew, contributing to algal blooms and aquatic dead zones.

Ocean noise

The ocean is far from being a “ silent world .” Sound waves travel farther and faster in the sea’s dark depths than they do in the air, and many marine mammals like whales and dolphins, in addition to fish and other sea creatures, rely on communication by sound to find food, mate, and navigate. But an increasing barrage of human-generated ocean noise pollution is altering the underwater acoustic landscape, harming—and even killing—marine species worldwide.

Anngu Chen/EyeEm

Consider the incessant din of the roughly 60,000 commercial tanker and container ships that ply the seas at any given time. The underwater racket that results creates a kind of “smog” that reaches nearly every corner of the ocean and shrinks the sensory range of marine wildlife. High-intensity sonar used by the U.S. Navy for testing and training causes some of the same effects—and has been linked to mass whale strandings .

Meanwhile, in the hunt for offshore oil and gas, ships equipped with high-powered airguns fire compressed air into the water every 10 to 12 seconds for weeks to months on end. Traveling as far as 2,500 miles, these deafening seismic blasts disrupt foraging, mating, and other vital behaviors of endangered whales (and may ultimately push some, such as the North Atlantic right whale , to extinction). The blasts lead some commercial fish species to abandon their habitat —a direct hit on coastal economies dependent on catch rates; they also injure and kill marine invertebrates, including scallops, crabs, and squid.

Offshore drilling

In addition to noise pollution, the oil and gas industry’s routine operations emit toxic by-products, release high levels of greenhouse gases, and lead to thousands of spills in U.S. waters annually. That oil can linger for decades and do irreversible damage to delicate marine ecosystems. Take the 1989 Exxon Valdez tanker spill in Alaska’s Prince William Sound, from which oil still remains, or the 2010 BP Deepwater Horizon offshore drilling disaster, which spread millions of gallons of oil throughout the Gulf of Mexico, imposing a heavy toll on coastal communities . But smaller spills also pollute the ocean (and the air) with long-lasting impacts. Even the most advanced cleanup efforts remove only a fraction of the oil, and sometimes they use hazardous technologies . Chemical dispersants used in the largest spill response efforts—1.8 million gallons were released into the Gulf after the BP disaster—are dangerous pollutants themselves.

NRDC works to defend our oceans

From the earliest days of NRDC’s founding, we’ve advocated—and litigated—to protect the world’s oceans. As political tides changed in Congress and the White House, NRDC has been steadfast in our defense of policies that protect marine species, as well as coastal communities and their ocean-based economies. In addition to advocating for climate policies that will ensure the health of marine ecosystems, NRDC has played a key role in halting offshore drilling and seismic blasting in the Arctic and Atlantic oceans, in the creation of the Atlantic’s first marine national monument , and in the push for more sustainable, ethical seafood . Today, we’re part of a growing coalition calling for governments to fully and highly protect at least 30 percent of our oceans by 2030 (part of what’s known as “ 30x30 ”) to help safeguard the marine ecosystems and fisheries that provide food, jobs, and cultural sustenance to billions around the world.

Ocean pollution and you

The fate of our seas is not only up to the government or industry. Our individual, daily actions matter too. You can start by reducing water pollution and runoff at home, being more mindful of your plastic consumption , or organizing a cleanup of your local waterway.

• The Causes And Effects Of Ocean Pollution

• More than 70% of the Earth is covered with water bodies that play an important role in our day-to-day life and form an indispensable part of our existence.
• Ocean pollution is caused by the introduction of toxic materials and harmful pollutants such as agricultural and industrial waste, chemicals, oil spills, and plastic litter into the ocean waters.
• Careless human activity has posed a serious threat to the ocean ecosystem, thereby affecting several species of marine flora and fauna as well as humans that are dependent on it.

More than 70% of the Earth is covered with bodies of water. Lakes, rivers, seas, and oceans play a vital role in our day-to-day life and form an indispensable part of our existence: food, transport, hydration, and temperature regulation are just some of the things they give us. So when these water sources are polluted, we humans feel the effects.

Ocean pollution refers to the introduction of toxic materials and other harmful pollutants such as agricultural and industrial waste, chemicals, oil spills, and plastic litter into the ocean's waters. The ocean provides humans with several resources and economic benefits, yet it is treated as a worldwide trash basin. This pollution of the world’s oceans is mainly caused by careless human activity that poses a serious threat to the oceanic ecosystem and in turn to several species of marine flora and fauna that are solely dependent on it.

Causes Of Ocean Pollution

There are several causes of ocean pollution. Some of the main causes are listed below. These are as follows:

Dumping Of Sewage

The dumping of sewage in the ocean is often regarded as the cheapest and easiest method of sewage disposal. Most of the untreated sewage containing lethal substances find their way into the ocean waters through the sewer systems and has detrimental effects on the health of marine flora and fauna.

Land Runoff

Referred to as non-point pollution, runoff is caused when the soil is infiltrated with water to its maximum extent and the excess water then flows from the land into the ocean via the drainage systems like rivers and streams. This runoff water carries with it the harmful toxins: the litter dumped in towns and cities, fertilizers, pesticides, and other soil contaminants. All these toxins are then dumped into the ocean along with the runoff.

Industrial Chemicals

The untreated effluents and garbage along with harmful chemicals are also released into water bodies from several industries. The waste from industries like fossil fuel, plastic manufacturing, agrochemicals and pharmaceuticals contains harmful toxins like mercury, DDT, phthalates, Bisphenol-A, and other chemical substances. These pollute the oceans by altering the pH level of the water which contributes to the death of most aquatic flora and fauna. Such toxins also enter the bodies of marine animals and accumulate in their tissues. They are further transferred up the food chain from one level to another, resulting in biomagnification when the concentration of toxins increases as it ascends the food chain. Large quantities of such biomagnified toxins ultimately reach humans through the consumption of different kinds of seafood.

Eutrophication

Researchers have noted that the increased concentration of harmful chemicals in the ocean leads to eutrophication . The presence of nitrogen-rich fertilizers, animal wastes, and human sewage triggers the explosive growth of marine algae and other life-threatening microorganisms that subsequently disrupt the ocean ecosystem. The depletion of oxygen due to eutrophication will also cause the death of marine fauna, resulting in the formation of dead zones in the ocean waters.

Ocean Acidification And Thermal Pollution

The ocean acts as a massive natural carbon sink by dissolving the atmospheric carbon-dioxide and excess heat in its waters. However, due to an increase in CO 2 levels due to global warming, the waters of the ocean are becoming increasingly acidic—a process called ocean acidification . The change in pH is already affecting coral reefs around the world leading to coral bleaching which has detrimental effects on marine life dependant on these reefs for their life cycle. 

Thermal pollution of the ocean waters is caused by the release of hot waters from power plants and processing companies into the ocean. It leads to a localized change in water temperature that, in turn, reduces the volume of oxygen dissolved in the water, killing marine life.

Oil spills result in the change of chemical composition of the marine ecosystems and also kill beneficial marine micro-organisms that generate oxygen. Such ecological imbalances lead to the smothering of the ocean’s biodiversity and result in reduced reproduction and migration, and the death of fish.

Noise Pollution

Unwarranted loud noise generated by passing ships for transportation and exploration activities is detrimental to marine life. Such unnecessary noise creates confusion in the marine environment by interfering with the acoustic information used by many aquatic species like whales and dolphins that rely on their sense of hearing for survival and other activities.

A large quantity of single-use plastics have been mercilessly dumped as litter into the marine environment and have been found on beaches, in polar ice seas, and even on the shorelines of the world’s most remote uninhabited islands. Plastic debris has been transforming some marine areas into a plastic soup, leading to the choking of marine life and causing a potential large-scale impact on the marine environment.

Rain and winds carry macro plastics including plastic bags, bottles, and other wastes into storm drains and rivers which act as conveyor belts dumping about 1.15-2.75 million metric tons of waste into the oceans every year. The sunlight and the ocean waves help to breakdown the macro plastics into smaller pieces of microplastics, which have now become a ubiquitous component of the marine and freshwater ecosystems. These microplastics are spread throughout the water column and have even reached the Mariana Trench , thereby underscoring the breadth of marine pollution.

It has been estimated from several studies that about 8 million tons of carelessly managed plastic litter enters the oceans annually, and this would increase by about three times in the upcoming decade. A report by the United Nations has claimed that by 2025, the oceans will contain one ton of plastic for every three tons of fish, and by the year 2050, the plastic waste will outweigh the fishes present in all the oceans of the world.

Effects Of Ocean Pollution

Ocean pollution has resulted in serious adverse effects on marine life as well as multiple negative impacts on the environment and human health. The harmful toxins and industrial chemicals that enter the oceans get accumulated in the fatty tissues of aquatic fauna and lead to severe damage to their reproductive systems. The sea birds that depend on the marine fishes for their food are also subsequently affected. When humans consume fish as seafood, they are also getting contaminated by these harmful chemicals. Oil spills prevent sunlight from reaching the aquatic flora and lead to a disruption of oxygen supply. Toxic chemicals and oil spills cause severe bleaching of coral reefs and results in the destruction of these fragile habitats and the life cycle of the coral animals. The fertilizers and pesticides that reach the oceans also contribute greatly to the global decline in fish populations as well as affecting the reproductive fertility of human beings that consume them.

National Geographic studies have revealed that more than 700 species of marine organisms ranging from tiny corals to majestic whales are facing a serious threat from plastic pollution. Researchers have estimated that about 1 million aquatic birds and 100,000 marine fauna are killed every year due to the ingestion of plastic materials. It has also been observed that marine organisms across all trophic levels have microplastics in their bodies, and these ingested chemicals and plastic materials wreak havoc on the behavior, development, physiology, and reproduction in a range of marine species. Studies on oysters have revealed that their reproduction rates have been almost halved. Several marine organisms have also been found entangled in abandoned fishing gears, ropes, and fishing nets. Stranded ocean plastic litter creates visual pollution and causes major economic damages to tourism, fishing, and shipping activities, posing a challenge for the countries that rely on them. The Great Pacific Garbage Patch which spanning 617,000 square miles between California and Hawaii is estimated to contain about 1.8 trillion tons of plastic debris.

Stay up to date:, future of the environment.

• The ocean floor's capacity to store vast amounts of carbon is a vital, if little-known, tool in the fight against climate change.
• Human activities, such as deepsea mining and bottom-trawling fishing practices, pose a threat to its potential.
• Ocean Decade (2021-2030) is an effort by the United Nations to better manage marine resources and protect 'blue carbon' stores.

“The science we need for the ocean we want” – this is the tagline for the UN Ocean Decade (2021-2030), which has just held its first conference in Barcelona , Spain.

Marine scientists from around the world, including me, gathered alongside global leaders to chart the progress of this ten-year mission to improve ocean health and marine biodiversity. That includes finding ways to better protect the seabed which we still know relatively little about.

Our ocean covers 70% of the world’s surface and accounts for 80% of the planet’s biodiversity. We can't have a healthy future without a healthy ocean - but it's more vulnerable than ever because of climate change and pollution.

Tackling the grave threats to our ocean means working with leaders across sectors, from business to government to academia.

The World Economic Forum, in collaboration with the World Resources Institute, convenes the Friends of Ocean Action , a coalition of leaders working together to protect the seas. From a programme with the Indonesian government to cut plastic waste entering the sea to a global plan to track illegal fishing, the Friends are pushing for new solutions.

Climate change is an inextricable part of the threat to our oceans, with rising temperatures and acidification disrupting fragile ecosystems. The Forum runs a number of initiatives to support the shift to a low-carbon economy , including hosting the Alliance of CEO Climate Leaders, who have cut emissions in their companies by 9%.

Is your organization interested in working with the World Economic Forum? Find out more here .

Some areas of sediment on the sea floor hold large stores of carbon. Without greater protection, disturbance from bottom-trawling fishing practices for example, could release some of that stored carbon back into the atmosphere.

I joined discussions in Barcelona that have led to the launch of a new sustainable ocean planning initiative , to be coordinated by Julian Barbière , global coordinator of the Ocean Decade. This aims to encourage commitment to sustainable management of 100% of sea area under a nation’s jurisdiction.

With this in place, there’s scope to reimagine the role of the ocean in our wider climate system and recognise that all marine natural systems sequester and store carbon in their soils and sediments.

I’m here on behalf of the global ocean decade programme for blue carbon – that’s any carbon that is stored in the ocean. This project is one of the UN’s 50 programmes aimed at delivering transformative ocean science solutions for sustainable development, connecting people and our ocean. That’s a big ask.

My work focuses on the extraordinary ability of coastal ecosystems – such as mangroves, salt marshes and seagrass – to sequester or store organic carbon in unusually high densities. Our blue carbon team of international research scientists from more than 20 countries is beginning to define emerging blue carbon ecosystems such as kelp forest and sub-tidal sediments as solutions to manage the climate and biodiversity crises.

The 360 million sq kilometres of ocean and sea floor, from coastal seagrass meadows to the sediment that slowly accumulates within the deepest trenches, are massively overlooked as a precious carbon store. Oceans hold vast stores of carbon – the top metre of the ocean holds an estimated 2.3 trillion metric tonnes.

The seafloor is not a resource to be relentlessly exploited, but a vulnerable repository of global biodiversity and carbon that needs protecting. These highly productive, yet vulnerable, ecosystems have been greatly affected by habitat loss and destructive practices such as deforestation of mangroves for shrimp aquaculture in the relentless development of the world’s coastal zones.

Blue carbon has huge potential to provide ocean-based solutions to help mitigate climate change, and thankfully, at the global scale at least, these losses have slowed in recent years .

The potential for blue carbon to reduce greenhouse gas emissions is relatively modest, but healthy, restored ecosystems have the potential to store an extra 2.96 million tonnes of carbon annually. Certain countries, such as Indonesia , offer huge potential as blue carbon hotspots where the protection and restoration of nature are an opportunity, for both the environment and local communities.

Carbon credits, the means by which additional carbon can become a source of investment income in that community, are gaining much interest. Off the coast of Kenya, the community-based Miko Pamojo project enhances direct benefits to local people from mangrove restoration.

Blue carbon ecosystems can help countries meet their climate obligations and have been attracting considerable interest. However, if nations want these ecosystems to continue to provide a whole range of services our governments must protect them and, where possible, restore lost habitats.

Most governments have been stubbornly slow to prioritise ocean-based solutions high up on the agenda of global climate negotiations. At this conference, I’ve heard more people, including Unesco’s director general Audrey Azoulay , driving home the need to protect and effectively manage our ocean resources.

Members from the traditional owners of the Great Barrier Reef spoke of “country” from a perspective of a long and sustained human relationship with nature and are intimately connected to the ocean. There is a growing recognition and respect for this indigenous knowledge and our need to integrate that into a sustainable ocean future.

Reimagining the ocean’s role

It makes sense to start by protecting these natural systems that already hold vulnerable stores of carbon – this is sensible risk management.

As nations continue to exploit the marine environment for fishing, fossil fuels and even precious metals which are now being mined from the sea floor in certain places, it is time to rethink the value of these vast natural stores of ocean carbon.

Space science gets way more funding than our oceans, yet vast areas of the global deep ocean remain largely unmapped. “ Life below water ” is by far the least funded of the UN’s 17 Sustainable Development Goals. That needs to change through a sustained and increased investment in ocean science and greater recognition for the value of our blue economy – defined by the UN as the sustainable use of the ocean’s resources for economic growth, improved livelihoods and jobs.

Stepping back to pause and preserve what already exists in the ocean can help the planet, and us, build resilience and create a healthier and more sustainable marine environment. The seabed forms the foundation for an interconnected ocean ecosystem and acts as an important long-term global sink for carbon that involves the whole ocean and its exchanges with the atmosphere and wider Earth system.

While plans are finally moving in the right direction, there are huge challenges ahead. To paraphrase Cynthia Barzuna , director of ocean action 2030 at the World Resources Institute, “there is no wealthy ocean without a healthy ocean”. The biggest takeaway from the Barcelona conference is that a sustainable ocean future depends on a shared vision that works for all of us and marine life too.

The World Oceans Pollution and Overfishing Essay

Introduction, ocean pollution, overfishing, whales and whaling, possible strategies for future ocean management, works cited.

Human beings have taken a lot of time to realize the need for ocean conservation to the extent that the ocean has succumbed to ecological challenges that have affected their lives in a variety of ways. Covering vast areas of the earth’s surface, the world oceans have a vital role in influencing both the terrestrial and otherworldly climates.

The limited accessibility of the oceans due to their vastness has left human beings with inadequate knowledge about their uniqueness. As a result, people undertake marine activities with less concern about the consequences of their actions. Industrialization, tourism, fishing, and shipping, among other human activities, have led to detrimental effects such as pollution, acidification, and overfishing.

These effects have threatened ocean life and created general ocean imbalance. All over the world, governments, private institutions, and non-governmental organizations have to advocate the protection of the ocean against destructive human practices that gradually deprive the ocean of its ambient nature. This essay explores pollution and overfishing as global issues that have led to devastation and depletion of ocean resources. It proves that pollution and overfishing are a threat to world oceans. It also suggests possible ocean management strategies to curb such a crisis.

Ocean pollution has become a debatable issue that has led to the promotion of sound ocean management by both governmental and non-governmental organizations around the world. Human society produces massive amounts of unwanted materials that find their way into the oceans once they are carelessly handled. Industrialization, tourism, agricultural activities, and shipping, among other activities, have significantly contributed to ocean pollution (McKibben 207). Industrialization is one of the major sources of ocean pollutants.

The author attests that inconsiderate discarding of plastic materials, industrial effluents, and solid wastes has considerably added to the contamination ocean. Use of chemicals for farming activities has led to contamination of rivers that eventually convey agronomic nutrients and untreated effluents to the oceans. These nutrients promote the growth of algae in the ocean. Algae produce algal toxins that kill fish due to intoxication (Johnson and White 60; Jenssen 198).

Furthermore, uncontrolled usage of landfills and careless dumping of industrial waste along riverbanks increases the rate of ocean pollution, a situation that increases the amount of marine debris. Tourist activities lead to increased disposal of plastic materials and other wastes on beaches. The action of tides and waves washes these wastes into the ocean, hence elevating the number of foreign materials. The overall effect of pollution leads to the poisoning of the ocean’s biodiversity.

Furthermore, Wafar, Venkataraman, Ingole, Khan, and LokaBharathi reveal that increased production of chemical-based products and components that are available in electronic goods (viz. computers, televisions, and radios), rubber shoe soles, synthetic flooring materials, clothing, and paper among other goods (6). The authors reveal that Europe alone produces about 10-percent out of an approximated number of 100,000 chemicals worldwide. Researchers claim that 3-percent of the chemicals produced in Europe are potential toxins if exposed to the environment (Wafar et al. 7).

According to the Stockholm Convention on Persistent Organic Pollutants, the chemicals released to the oceans through improper disposal may change their chemical composition to form increasingly lethal substances that intoxicate flora and fauna (Roberts 27). The author reveals that inconsiderate disposal of chemical-based elements exposes the ocean to persistent organic pollutants (POPs). These pollutants are toxic and non-degradable (Roberts, 28). They clog onto the tissues and organs, thus leading to intoxication and deaths of sea animals and plants.

Moreover, ship accidents cause oil spills that have severe economic and ecological implications. The marine ecosystem is self-regulating and constantly fluctuating by its complexity. Any alien influence such as oil spills that can lead to ecosystem imbalance leads to death, reduced reproduction, and migration of fish. Oil changes the chemical composition of the ambient ecosystems, a situation that results in smothering of the oceans’ biodiversity. Also, oils consist of toxic substances that poison ocean animals and plants. Deaths of animals and plants provide a suitable medium for the growth of algae.

The ocean is the habitat of hundreds of fish species, most of which comprise human food. However, Hutchings, Côté, Dodson, Fleming, Jennings, Mantua, Peterman, Riddell, and Weaver reveal that the fisheries industry has succumbed to unsustainability due to illegal and unregulated fishing (225). Brunch reveals that the ocean loses over 85 million tons of fish to fishing to supply human society with rich protein meat (2). There is lessened control of overfishing activities because of inadequate incentives to facilitate ecosystem monitoring and surveillance.

Additionally, the author emphasizes that unwillingness to accept short-range expenses blinds the concerned management bodies from seeing the long-standing benefits that come with effective fish ecosystem management. Overfishing is highly disruptive to the ecosystems’ food chain (Branch 3). A research carried by the State of World Fisheries and aquaculture (SOFIA) indicated that 86-percent of the ocean population is either overexploited or recuperating from overexploitation (Hutchings et al. 226).

The authors predict that the exploitation percentage will rise to about 90-percent if unsustainable fishing methods continue in the next two decades. A separate study by Beaugrand, Rombouts, and Kirby in 2007 to determine the level of fish depletion revealed that 28-percent of the world’s commercial fisheries have collapsed because of overfishing and habitat contamination (441).

Whales are social marine animals that exhibit a variety of social and communication behaviors that depend on the whale species. Whaling is a marine activity that involves hunting of whales for meat, oils, and blubber, whether for domestic or commercial purposes. Seemingly, commercialization of whaling that has led to killings of thousands of whales per year has become an international debate over the whaling practices (Blok 43). Close to four decades ago, the then few numbers of whales nearly reached extinction.

This situation led to the establishment of the International Whaling Commission (IWC) that banned whale hunting for business purposes (Wesolowski 102). Despite the ban of whaling, some countries such as Japan, Norway, and Iceland still practice marine activity. According to Blok, these countries have continued to commercialize whaling regardless of the lessening demand for whale products (51).

The author reveals that the three countries terminate the lives of over two-thousand whales annually. Wesolowski links the continuation of illegal commercialization of whaling products to the special authorization to kill whales for scientific purposes. This form of licensing has created loopholes that have led the killing of increasingly higher numbers of whales.

Pollution has become a scary crisis for ocean management that demands immediate resolution. The devastating effects that come with the disposal of contaminants in the ocean have significantly put the life of marine biodiversity at great risk of poisoning, death, and even extinction (McKibben 258). The international conventions should implement policies that govern producer-responsibility for using plastic packaging materials.

Regional and international governmental and non-governmental agencies should foster advocacy for eradication of non-degradable packaging materials, especially dangerous plastics that can react with other ocean contaminants to produce toxins. Although numerous non-governmental organizations have addressed the issue of pollution and derived various methods of reducing ocean contamination, there is a need for empowerment of world communities, especially the ones that depend on marine activities for economic purposes in an attempt to change their attitudes towards ocean use (McKibben 341)

Furthermore, the rate of depletion of ocean resources has compelled governmental and non-governmental organizations to advocate better ocean management strategies. They have made major attempts to address the issue and raise awareness on the importance of effective ocean management practices to save the ocean biodiversity that forms a rich source of food for the human society.

However, ocean political matters have greatly affected the implementation of globally accepted marine management laws. The need for sound management has become inevitable. Therefore, proper management strategies should aim at balancing a socio-economic, ecological, and scientific interest in the use of ocean resources. Marine activities should take into account objective aspects such as controlled fishing practices and ecosystem sustainability (Sesini 12).

Also, regional and international government agencies should work together with non-governmental organizations to establish conventional regulations and procedures for sustainable marine practices. Beaugrand, Rombouts, and Kirby reveal that some countries in Europe have embraced strict regulations and fishing techniques that align with Europe’s obligation for protection and preservation of the marine habitats (445). Although not all countries abide by the standards for sustainable marine activities, the authors reveal an increasing adherence to international agreements on the protection and preservation of marine environments.

For instance, the London Convention controls the dumping of industrial effluents and other wastes in rivers and oceans. Wafar et al. suggest three important areas that demand more focus than ever to ensure ocean sustainability (9). The authors explain that the combination of a well-structured risk management reform, establishment of marine protected areas, and certification of marine incentives will develop into sustainable marine practices. Also, the conventions should define clear utilization of market strategies to improve ecological and economic sustainability (McKibben 337).

The overall health of the various oceans is at risk due to the persistent and uncontrolled human activities that have led to the depletion of resources from day-to-day. The size of plastic trash that enters the ocean heightens every year due to increased production in the industrial sites and packaging of fast goods, especially food materials.

Ocean acidification and increasing marine debris have also challenged the ocean environment. Researchers have suggested that further elevation of these forms of pollution will lead to increased destruction of ocean life by approximately 10 percent in the next decade. In reality, such an increase will tremendously affect the socio-economic sectors of many countries around the globe, owing to the elevated reliance on ocean resources. Overfishing has claimed huge numbers of fish from the ocean.

This situation has endangered some of the fish species since fish harvesting has exceeded their reproduction rates. Therefore, the development of a sustainable ocean ecosystem remains a crucial step that governmental and non-governmental agencies should prioritize with a view of advocating the protection and preservation of marine resources. There is an escalating need for formulation and implementation of dependable regional and international policies to control overfishing and ocean pollution.
