The Effects of Water Pollution on People and Animals

Ocean acidification: solutions, impact and causes, ocean acidification: solutions to the grave environmental concern, ocean acidification: solutions and threats, addressing the urgent issue of ocean acidification, tackling a global crisis: marine plastic pollution, protecting marine life and coastal ecosystems, balancing development and conservation for sustainable oceans.

Ocean pollution, or marine pollution, occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.

Marine debris pollution, plastic pollution, ocean acidification, nutrient pollution, toxins, underwater noise, and other.

There are many ways to categorize and examine the inputs of pollution into marine ecosystems. There are three main types of inputs of pollution into the ocean: direct discharge of waste into the oceans, runoff into the waters due to rain, and pollutants released from the atmosphere.

Ocean pollution has many consequences, such as: harm to marine animals (cancer, behavioral changes and inability to reproduce), depletion of oxygen in seawater, threats to human health (cancer and birth defects).

100 million marine animals die each year from plastic waste alone. The largest trash site on the planet is the Great Pacific Garbage Patch, twice the surface area of Texas, it outnumbers sea life there 6 to 1. 70% of our debris sinks into the ocean's ecosystem, 15% floats, and 15% lands on our beaches. 80% of global marine pollution comes from agriculture runoff, untreated sewage, discharge of nutrients and pesticides.

Don’t let the plastic get into the ocean.

• Don’t Let the Plastic…

May 2, 2018

Guest post by Mark J. Spalding, President, The Ocean Foundation

23 April 2018

Do you use your reusable water bottle and coffee mug?

Do you use your reusable shopping bags?

Do you remember to say “no straw” when ordering a drink?

Good for you! You’re part of the solution.

Do you own a fleece vest or throw?

Do you own yoga wear or other synthetic clothing items?

Sorry. You’re part of the problem, too.

We all know that plastic waste is a problem. It is a particular problem for the ocean. Currently approximately 8 million metric tons of plastic waste enters the ocean every year! That’s enough to line every foot of our coast.

Ocean plastics can loosely be categorized in the following ways:

Marine Debris— This includes everything from construction materials to beer coolers, but when we’re talking about ocean plastics, we generally mean the bigger pieces that are easily seen and can readily be picked up. Part of this is debris from marine sources such as fishing gear.

Microplastics— These are the tiny pieces that plastic breaks into over time—not disintegrating, but simply fragmenting, making it ever more accessible to marine life. Microplastics are found in every part of our global ocean.

Microfibers— These are the very tiny fibers from your fleece, athletic, or other synthetic clothing that shed every time you wash them in a machine. They are everywhere in the ocean as well as in lakes, rivers, streams, and even your drinking water.

So, what does plastic in the ocean do? Some effects are not fully understood—such as the degree to which microfibers themselves or the toxins they carry cause harm in humans and other animals and at what scale. Others we know all too well.

Plastic poisons and injures marine life as shellfish, corals, and other marine life eat microplastics and fibers as they filter for real food. Whales, fish, and other animals get entangled in derelict fishing gear and other debris and die a slow painful death from asphyxiation or starvation. When animals—sea birds and corals for example—take in plastics, it leaves no room for real food—and they suffer starvation as a result.

Plastic is capable of emitting and absorbing or carrying all types of toxins, including flame-retardants and pesticides (DDT). Small pieces of plastics e.g. microplastics (microbeads, microfibers) can serve as vector for chemicals to get into the bodies of marine animals, where they can accumulate in fat cells. These can damage tissues and organ function. They can be absorbed into the brains of fish, altering behavior. Plastic is also a vector for bacteria and viruses.

These properties of plastic, especially microplastics, have implications for human health as we consume fish and shellfish. Two Belgian researchers, looking at the amount of microplastics in some shellfish, concluded in 2014 that the average European seafood consumer could be eating 11,000 pieces of microplastic every year. And that’s just in shellfish (mussels in particular in this case).

Plastic litters our beaches and landscapes which in turn affects tourism revenue. It’s no surprise that people like to visit clean beaches more than dirty ones. It also affects community health not only for the reasons above, but because plastic waste can collect water, allowing disease-bearing mosquitoes to breed, and poorly managed debris can clog the outflows of rivers and streams, causing flooding.

So, what is it about single-use plastics? They represent somewhere between a third and a half of all global plastics production, which reached about 335 million metric tons in 2016. Some single use plastics should stay that way—especially for hypodermics and other medical uses. Others should be used only when and where they meet a unique or emergency need—think plastic straws, bottled water, bottled sodas, and plastic packaging—and that’s probably not in the EU or the US. Finland is one leader on plastics management, the European Union is doing quite well over all.

The scale of use is overwhelming. We buy about 1 million plastic bottles every minute of every day! Where sanitation is a huge problem (e.g. hurricanes, floods, etc.) bottled water is a public health good and delivery in plastic is cheaper. But for daily use, it’s the more expensive choice, has a huge climate footprint, and is a big part of the plastic waste mismanagement problem. Only 1 percent of the 4 trillion plastic bags used annually is recycled. We use half a BILLION plastic straws a day in the U.S. alone—almost two for every man woman and child!

So where is the plastic coming from besides littering? More than two billion people live without any waste collection. In China, Indonesia, Vietnam, Thailand and the Philippines ― which were identified in a 2015 Ocean Conservancy report as the top five plastic-polluting nations in the world ― the amount of mismanaged waste was close to 75 percent or more of the total waste generated. Getting a handle on that source at scale is a slow process because of the nature of governance in those countries and the ways in which waste disposal is managed.

Landfills can leak harmful pollutants into the watershed and plastics on top of a landfill can be carried away by the wind and rainwater. Out of 50 largest uncontrolled dumpsites around the world, 38 of these are on the coast and spill directly into the sea. Thanks to sea level rise and storms, coastal landfills are eroding everywhere creating challenges for waste managers even in places where waste management has been reasonably well-addressed. The United States is one of the world’s top five waste-generating developed countries.

Plastic waste to enter the ocean from land is expected to increase tenfold within 7 years. Can you even visualize 80 million metric tons?

More on the Danger to fish and humans:

What are the Trends? New uses for plastic are being discovered all the time—and the demand for lightweight, flexible, sterile, and inexpensive packaging and other materials grows as the population grows. Plastic production is growing exponentially and is expected to double again in 20 years. Thus, plastic waste is too.And, we’re not doing a great job of managing it. As of 2015, 6,300 million metric tons of plastic waste has been generated since the end of World War 2. Only about 9 percent of that has been recycled—the rest was burned, is sitting in landfills, or is slowly breaking into smaller pieces on land or in the water.

Perhaps the most famous example of the scale of the plastic problem in the ocean is the ever-expanding “Great Pacific Garbage Patch,” a gyre in the Pacific Ocean where currents and winds have fostered the movement of plastic waste into a defined area. The Patch is a mixture of marine debris, microplastics, and ocean life including microscopic crabs hitching a ride—and now covers an area three times the size of France! And it is just one of the five ocean gyres where plastic has collected.

But as famous as the Patch is, the sad truth is that plastic waste—at every scale—is found throughout the global ocean, in bays and estuaries, in the deepest crevasses, and the coastal marshes, mangrove forests, and seagrass meadows. It is everywhere.

So, how do we end plastic pollution?

We’re human. We’d like to engineer away the problem- like a magic pill to lose weight or live forever.

What removal system is being tested? It is likely you have heard of the young Dutchman Boyan Slat and his ocean boom system. The idea is that the booms will be towed out to the Pacific from San Francisco to begin operating next July. The system involves hanging nets from booms (made, of course from plastic pipe) and using drifting anchors positioned almost 2000 feet down to tap into where the ocean currents are slower than they are at the surface.

The idea is that the floating plastic debris will move faster than the booms, and thus be concentrated into a central area held by the booms. Fish and other sea life are expected to swim under the nets. Ships are to collect the gathered trash once a month to convert it to pellets or other purposes. Slat raised $2.2 million in crowdfunding from 40 countries, and millions more in California to test the prototype and begin the process of moving it thousands of miles out to sea for deployment.

The challenges include the potential for “corralling” of ocean life; addressing the incredible amount of energy (and expense) to go out to collect the trash and transport it back; as well as unintended consequences. And, of course, this collects plastic of a certain size at the surface and not the debris that has sunk nor the microplastics found everywhere. Booms have proven to be one good way to capture debris in streams and rivers to prevent their migration to the sea.

Prevention is key. The plastic already in the ocean is nearly impossible to collect, especially at scale, without harm to sea life.

It’s very simple really: Don’t let the plastic get into the ocean.

What you can do with your friends, colleagues, and family: Collectively, we are addressing many of the key problems, beginning with promoting personal action. None of what we recommend is new, and we hope repetition helps. Bad habits are hard to break—especially when it’s easier to just go with the plastic flow! The people who make the biggest difference are the ones who do the little things consistently.

• Water: If you use a reusable water bottle, you personally could avoid an average of 156 plastic bottles annually—this sounds like a small thing but it’s doing your part and multiply it by everyone in your office, home, or school, and it really starts to add up. Likewise, bring your coffee mug with you—the go-cup might be paper, but the lid is probably not.
• Carriers: Bringing your own bag to shop (and carrying one with you just in case) can help make a dent in those 4 trillion plastic bags used each year. Bag fees and bag bans do work to reduce waste—with immediate effect on cleanup statistics as to what is collected following their implementation.
• Straws: Remembering to ask for no straw can become a habit. Straws only by request is a huge first step—and a great thing to ask of your favorite restaurant. Paper and reusable straws are an option too—and the movement is slowly growing.
• Clothing: Limit how often you wash synthetic clothing, including fleece. Seek out natural fibers (bamboo, cotton, wool, etc.).
• Entertainment: Remember our roots—we can use glasses, cloth napkins, and real cutlery at events as much as we can. We can use compostable tableware, napkins, and other products (and compost them).
• Prevention: Beach, stream, and river clean ups actually help, even though they seem like a drop in the bucket. Many organizations host regular clean ups and we need everyone to pitch in and pick up in their own neighborhood.

Personal Action is a big start— but real change has to be regional, national, and even global in scale.

We are positioning plastic pollution as a major environmental and transnational problem—

• multiple movies, events, and other outreach seems to have drastically increased ocean plastics awareness,
• educated/mobilized citizens demand less plastic, and

choose to reject plastic where we can identify safer alternatives

• increased public awareness of the role of NGOs in working towards change, especially where NGOs are working with governments at every level in Southeast Asian countries, and
• increasing the public expectation that solutions will be implemented.

I should note that we all can be part of the outreach. A good starting point is Earth Day Network’s toolkits and web-based content to educate and support behavior change and action for different audiences.

Existing studies have shown us the sources and some of the pathways towards cost-effective solutions, but waste management and pollution prevention is a government scale challenge. Countries and corporations have to do their part—the public truly understands and expects them to fulfill this role.

And there is an inherent financial incentive to do so even beyond the obvious benefits. For example, governments and tourism businesses know that a clean beach makes money, and a dirty beach turns visitors away. The same sort of argument can be made for better waste management everywhere. Likewise, good waste management has a positive impact on public health which also reduces costs and increases productivity.

Corporations are working on a variety of solutions, some that monetize ocean plastics, and others that address a challenge. Patagonia and other outdoor clothing manufacturers are striving to figure out how to address the microfiber problem especially since synthetics have their own advantages. Adidas is producing the first shoe made from recycled ocean plastic. Bureo has its skateboard decks made from recycled fishing gear. Norton Point has its “Tide” line, featuring sunglasses made from recycled ocean plastic.

We need national government policies that mimic the European Union’s guidelines for waste and to promote the adoption of a global framework to regulate plastic pollution. Such polices:

• aim to PREVENT the generation of waste
• contribute to the REUSE of waste
• REDUCE the adverse effects of  waste management

Governments need to respond to, and work with, NGOs organizing on the ground to promote waste management practices that improve public health and water quality. Some NGOs are working with small island communities to identify ways to substitute fuel or use alternative methods to burning plastic trash for cooking fuel—a practice that is harmful to humans and marine life alike.

To address packaging, we can all support policies in our communities that charge fees for plastic bags that in turn pay for cleanup and restoration and promote circular economy solutions to excess packaging waste. When local efforts to address plastic pollution are stymied by state governments, we can work to educate our legislators about the costs of dealing with plastic waste and the need for local and state action to reduce the amount we use it in the first place.

The R&D costs for alternatives to plastics, for better, cost-effective, and energy-efficient recycling methods, and to define cost-effective clean up solutions is way beyond more non-government organizations’ capacity. It’s a role for countries and corporations, and some exciting projects are under way.

For example, in 2016, Japanese scientists reported the discovery of bacteria that is able to digest polyethylene terephthalate (PET)—the plastic primarily used for making plastic bottles—in less than six weeks. More recently, scientists from the University of Portsmouth in the U.K. and the National Renewable Energy Laboratory in the U.S say they have engineered a plastic eating enzyme from that bacteria that breaks down PET even faster. It is going to now be tested on an industrial scale to see if it improves the management of plastics—better broken down into its constituent parts and reused than sitting in a landfill or blowing into the ocean. It is also to be hoped that any large-scale production of bacteria and enzymes is monitored carefully and managed for unintended consequences.

It is also possible that these processes will prove to be a cost-effective way to turn plastics back into constituent parts as fuel that can be used to generate electricity. Waste to energy also includes burning plastics for fuel, but we have to do it cleanly to avoid air pollution problems.

Personal action, corporate programs, and government strategies offer opportunities to address the global challenge of plastic pollution and the harm it inflicts on our ocean.

There is hope. All we have to do is to stop putting bad stuff into the ocean! And, this is why we get up each morning.

ENCYCLOPEDIC ENTRY

Marine pollution.

Marine pollution is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide.

• Marine Pollution (Google Doc)

Marine pollution is a growing problem in today’s world. Our ocean is being flooded with two main types of pollution: chemicals and trash.

Chemical contamination, or nutrient pollution, is concerning for health, environmental, and economic reasons. This type of pollution occurs when human activities, notably the use of fertilizer on farms, lead to the runoff of chemicals into waterways that ultimately flow into the ocean. The increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms , which can be toxic to wildlife and harmful to humans. The negative effects on health and the environment caused by algal blooms hurt local fishing and tourism industries.

Marine trash encompasses all manufactured products—most of them plastic —that end up in the ocean. Littering, storm winds, and poor waste management all contribute to the accumulation of this debris , 80 percent of which comes from sources on land. Common types of marine debris include various plastic items like shopping bags and beverage bottles, along with cigarette butts, bottle caps, food wrappers, and fishing gear. Plastic waste is particularly problematic as a pollutant because it is so long-lasting. Plastic items can take hundreds of years to decompose.

This trash poses dangers to both humans and animals. Fish become tangled and injured in the debris , and some animals mistake items like plastic bags for food and eat them. Small organisms feed on tiny bits of broken-down plastic , called micro plastic , and absorb the chemicals from the plastic into their tissues. Micro plastics are less than five millimeters (0.2 inches) in diameter and have been detected in a range of marine species, including plankton and whales. When small organisms that consume micro plastics are eaten by larger animals, the toxic chemicals then become part of their tissues. In this way, the micro plastic pollution migrates up the food chain , eventually becoming part of the food that humans eat.

Solutions for marine pollution include prevention and cleanup. Disposable and single-use plastic is abundantly used in today’s society, from shopping bags to shipping packaging to plastic bottles. Changing society’s approach to plastic use will be a long and economically challenging process. Cleanup, in contrast, may be impossible for some items. Many types of debris (including some plastics ) do not float, so they are lost deep in the ocean. Plastics that do float tend to collect in large “patches” in ocean gyres. The Pacific Garbage Patch is one example of such a collection, with plastics and micro plastics floating on and below the surface of swirling ocean currents between California and Hawaii in an area of about 1.6 million square kilometers (617,763 square miles), although its size is not fixed. These patches are less like islands of trash and, as the National Oceanic and Atmospheric Administration says, more like flecks of micro plastic pepper swirling around an ocean soup. Even some promising solutions are inadequate for combating marine pollution. So-called “ biodegradable ” plastics often break down only at temperatures higher than will ever be reached in the ocean.

Nonetheless, many countries are taking action. According to a 2018 report from the United Nations, more than sixty countries have enacted regulations to limit or ban the use of disposable plastic items.

Ocean Pollution Essay 500 Words

The world’s oceans are the cradle of life, covering over 70% of the Earth’s surface and providing a home to diverse ecosystems. However, this vast expanse is facing a looming threat: pollution. Ocean pollution, primarily caused by human activities, poses a severe risk to marine life, ecosystems, and ultimately, human well-being. This essay delves into the causes, effects and potential solutions to address this pressing issue.

What are the main causes of ocean pollution?

There are many causes of Ocean pollution, originating from various human activities.

Plastic Pollution

One of the primary causes is plastic pollution. Each year, millions of tons of plastic waste enter the oceans, adversely impacting marine life. Improper disposal, inadequate recycling systems and the extensive use of single-use plastics contribute significantly to this issue.

Microplastics Pollution

Microplastics, the breakdown of larger plastic waste, have infiltrated even the most remote ocean areas, posing a significant threat to marine life due to their ingestion by various species, causing widespread harm.

Chemical Pollution

Moreover, chemical pollutants from industries, agriculture, and households find their way into waterways, eventually reaching the oceans. These pollutants, including pesticides, heavy metals, and oil spills, disrupt marine ecosystems, affecting the health of aquatic organisms and causing long-term damage.

Pollution from deep sea mining

Deep-sea mining, the extraction of minerals from the ocean floor, raises concerns about potential pollution. The process disturbs seabed deposits, releasing toxic elements and heavy metals into the water. Mining activities create plumes that spread particles across wide areas, potentially harming marine life and disrupting deep-sea ecosystems. To safeguard ocean health, it’s crucial to conduct thorough research, regulate these activities and develop responsible mining practices that minimize the environmental impact.

Pollution from nutrient runoff

Another significant contributor to ocean pollution is nutrient runoff. Excessive use of fertilizers in agriculture leads to nutrient-rich runoff entering water bodies. This influx of nutrients causes harmful algal blooms, depletes oxygen levels and creates dead zones, severely impacting marine life.

Pollution from Military Activity

War and military activities contribute to ocean pollution through actions like naval battles, bombings and deliberate or accidental damage to ships and coastal facilities. These events result in the release of hazardous materials, oil spills and munitions into the sea, posing a threat to marine ecosystems. Disposing of munitions and chemical agents also leaves a lasting impact on the health of the oceans.

Pollution from Space debris

Space debris, resulting from satellites and space equipment, contributes to ocean pollution when it falls into the seas. These remnants, upon re-entry into the Earth’s atmosphere, pose a risk to marine life and habitats. Their materials can introduce foreign elements, potentially harming ocean ecosystems. Responsible space exploration practices are vital to minimize the environmental impact on our oceans.

Pollution from Discharge from ships

Discharge from ships, including ballast water, fuel leaks and waste disposal, significantly contributes to ocean pollution. Ballast water , often containing invasive species, is released into different ports, disrupting local marine ecosystems. Fuel leaks and deliberate waste disposal add oil, plastics and other harmful substances into the ocean, directly impacting marine life and habitats. Stringent regulations and the adoption of cleaner technologies are essential to reduce ship discharges and protect our oceans from further contamination.

Effects of Ocean Pollution

The effects of ocean pollution are farfetched. Every pollutant affects the marine ecosystem in a unique way.

Death or Injury of Marine Species

The consequences of ocean pollution are far-reaching and devastating. Marine life suffers immensely, as various species become entangled in or ingest plastic debris, leading to injury or death. Sea turtles mistake plastic bags for jellyfish, while seabirds feed plastic particles to their young, causing starvation and reproductive issues.

Acidification of oceans

The acidification of oceans due to increased carbon dioxide absorption not only impacts marine life but also threatens coral reefs and shellfish, affecting the entire oceanic food chain.

Chemical, Communities and Contamination

Chemical pollutants pose a threat to the reproductive, immune, and endocrine systems of marine creatures. Oil spills have catastrophic effects on ecosystems, killing fish, contaminating habitats, and affecting the livelihoods of communities dependent on marine resources.

Garbage Patches

Furthermore, the accumulation of plastic and other debris forms massive garbage patches, such as the Great Pacific Garbage Patch, altering ocean currents and harming marine habitats.

Human health and Economies

Ocean pollution also impacts human health and economies. Contaminated seafood poses health risks and the decline of fisheries due to pollution affects food security and livelihoods in coastal communities. Additionally, the degradation of coastal areas and loss of biodiversity have significant economic repercussions, impacting industries like tourism and fisheries.

Solutions to Ocean Pollution

Addressing ocean pollution requires a cumulative approach involving global cooperation and individual responsibility. Encouraging the development and implementation of more efficient wastewater treatment methods can significantly reduce the discharge of pollutants from industrial, agricultural and urban sources into water bodies. Some potential solutions include:

• Reduction of Single-Use Plastics : Governments, industries and individuals should work towards reducing single-use plastics by promoting reusable alternatives and implementing policies that discourage their use.
• Improved Waste Management : Enhancing waste management systems, implementing recycling programs and increasing awareness about proper disposal can significantly reduce the amount of waste entering oceans.
• Regulation and Enforcement : Stricter regulations on industrial waste disposal and fishing practices, along with effective enforcement mechanisms, are crucial to prevent further pollution.
• Innovation and Research : Supporting innovative solutions such as biodegradable plastics, ocean cleanup technologies and sustainable fishing practices can significantly mitigate ocean pollution.
• Education and Awareness : Promoting education and awareness campaigns to foster a sense of responsibility and environmental stewardship, empowering individuals to make informed choices that benefit the oceans.

Ocean pollution is a global crisis that demands urgent attention. Its causes are deeply rooted in human activities and its effects are widespread, impacting marine ecosystems and human well-being. However, with collective efforts, sustainable solutions can be implemented to reduce the hazards and eventually eliminate this threat. Governments, industries, communities and individuals must work hand in hand to restore and protect our oceans, ensuring a healthier and more sustainable future for all.

Ocean Pollution Essay 250 Words

Ocean pollution, a result of human activity, involves substances entering the sea and causing detrimental effects. The majority of these pollutants—around 80%—emanate from human activities on land, with marine transportation contributing significantly. This mix of chemicals and waste, derived mainly from land-based sources, damages ecosystems, threatens organism health and disrupts economies globally. Since much of the input comes from land, coastal areas are particularly vulnerable to pollution. Air pollution further exacerbates the problem by carrying various substances into the ocean from the atmosphere.

The different types of marine pollution encompass marine debris, plastic pollution (including microplastics), ocean acidification, nutrient pollution, toxins and underwater noise. Plastic pollution, from large items to tiny microplastics, and marine debris poses a significant threat to marine life. Nutrient pollution, primarily from agriculture and sewage disposal, leads to harmful algal blooms, causing adverse effects on both human health and marine creatures.

Toxins from potentially harmful chemicals are absorbed by plankton and benthic animals, accumulating within the ocean food chains. Pesticides incorporated into marine ecosystems can cause mutations and diseases, affecting both marine life and humans. Similarly, toxic metals introduced into marine food webs alter tissue matter, behaviour and reproduction in aquatic organisms. Even land animals and the food derived from them can be affected by marine toxins.

The impact of ocean pollution is far-reaching and critical. It threatens not only marine life but also the intricate balance of our ecosystems and the health of our planet as a whole. Addressing this challenge requires immediate action and collective responsibility to ensure the protection and preservation of our oceans for the well-being of all life on Earth.

Speech on Water Pollution for Students and Children

Speech on water pollution.

Water pollution is a very serious environmental issue that we are facing right now. Water gets polluted when the physical, biological and chemical properties deteriorate due to human activities. Further, water pollution is responsible for impacting the lives of humans and animals as well. It is extremely hazardous to the environment and must be curbed right away. You might think that the water you drink daily is clean but it contains pollutants. Thus, we need to adopt measures that will help prevent water pollution on a global level for a healthier lifestyle.

Critical Concern

As mentioned above, water pollution is a significant threat to the ecosystem and the sustenance of life. The major cause responsible for water pollution is definitely the industries that dump waste into water bodies. They do not properly treat the waste and directly dump the harmful toxins in the water.

Thus, it hampers the quality of aquatic life badly. The aquatic species consume the harmful chemical which is present in the water and die because of it. Consequently, it is a huge threat to the ecosystem whether on land or water. Moreover, these chemicals also reduce the oxygen content in the water bodies.

Further, we see that the brutal use of fertilizers and pesticides that are done in the agricultural sector pollutes the water bodies greatly. When the discharge is not regulated and sanitation is not proper, it contributes to water pollution. Moreover, the humans and animals who consume this water from the polluted water bodies have a negative impact on their health.

Besides, these polluted water bodies have become home to bacteria and germs. Thus, they cause waterborne diseases and epidemics like diarrhoea, cholera, and more. Similarly, they also contaminate underground water when it seeps through the soil.

Thus, we need to prevent water pollution by adopting proper waste management policies. A single organization, government or individual won’t be able to accomplish this task. We need to do it collectively.

Ways to Prevent Water Pollution

We can all collectively control water pollution to a large extent. We need to realize that pollution’s solution is dilution. There are several methods through which one can control water pollution. To begin with, the sewage pollutants contain a lot of toxic materials. So, they must be chemically treated in order to make them less toxic.

A factor which contributes to this pollution is organic insecticides so we can reduce it by using less stable chemicals in their manufacturing process. Further, there must be regulation of industries, as they shouldn’t be allowed to dump the waste into water bodies.

Similarly, there must be proper sewage treatment plants in every city. This will allow using the same water in factories and also irrigation. Moreover, this water can also serve as a great fertilizer. In addition, we must also adopt measures to reduce the occurrences of oil spills.

On an individual level, we can also do our bit to prevent water pollution. Begin by saying no to plastic as it remains in our oceans for thousands of years. Reuse the items so there is less waste production. Try limiting the use of detergents and bleaches, and if necessary, use environment-friendly detergents.

All in all, it is very essential for all to start practising a lifestyle which does not contribute to water pollution. We need water to survive and there won’t be life without it. Thus, to make the world a better place for the upcoming generations, we must start working from now.

• Speech on Water Pollution

Speech on Water Pollution in English for Students

Water pollution is the contamination of water usually by human activities such as throwing garbage and sewage waste in clean water bodies. Due to the continuous use and exploitation, there is water pollution occurring all around us. Water pollution is one of the most important issues which every country is facing right now. 

If you are looking for a persuasive speech about water pollution, refer to the speeches below - a long speech on water pollution and a short 2 minutes speech on water pollution. These informative speeches will help the students to understand the what, why, and how’s of water pollution.

Long Informative Speech About Water Pollution

Hello, everyone. Thank you for having me. Today I want to talk about water pollution, its causes and how it can be controlled.

Water is the basic need for survival. It has been used by living things for ages. Life without water cannot be imagined. Water is the most important element that cannot be replaced by any other element. Due to the continuous use and exploitation, there is water pollution occurring all around us. 

Water pollution is one of the most important issues which every country is facing right now. Water pollution is the result of continuous economic growth. As the population grew, water was exploited with that. The main source of water pollution includes the overflow of domestic sewage in clean water bodies. Dangerous organic and chemical waste from industries is dumped in various river bodies. The toxic chemicals present in industrial waste not only pollute water but also kill aquatic life. 

The major pollutant industries are fertilizers, pesticides, refineries, metal plating, etc. Sewage waste and garbage from houses are carelessly thrown into clean water bodies by the citizens. 

Water pollution remains a major issue in most developing countries which includes India. In India, many people die because of water pollution. Around 80% of India’s water bodies are severely polluted as people dump raw sewage and garbage into the rivers and lakes. This has led to water being undrinkable and which in turn causes the vast majority of the population to heavily rely on expensive drinking sources. The condition of water pollution is so bad in India that every year 1.5 million children die from malaria. 

Reasons for India’s increased problem in water pollution are that India suffers from urbanization, Unauthorized slums have been established and no proper pipelining by the government. Due to overpopulation, many underprivileged people decide to live in slums where they drink contaminated water which causes diseases. Another reason is no proper pipelining is done by the government as a result of which the sewage water gets mixed up with the drinking water. The industries in India release organic and chemical waste directly into the water bodies. To sum up oil leaks, poor sanitization, no proper waste, and sewage treatment, and open defecation are considered to be the leading cause of water pollution in india . Children drink this contaminated water that causes a major bacterial attack on the digestive system, which results in diseases like diarrhea, etc. 

So, how can we control this problem? Well, the government should adopt more scientific and improved methods for handling the disposal of sewage and garbage. To control the spread of diseases, a proper method of sterilization of water should be developed. When it comes to Industries, the harmful industrial effluents should be neutralized and properly before discharging into water bodies. When it comes to agriculture, a minimization should be done in the use of chemical fertilizers and pesticides. 

To conclude, I want to say that water pollution is the result of the negligence shown by mankind. I believe it’s a warning by mother nature towards us to take care of our water bodies. As a citizen and a fellow human, it is the duty of each and every person to take care of water bodies around. Do not throw garbage and waste into river bodies. As a citizen, make sure that no one is also polluting the water bodies. Water pollution cannot be eliminated, but it could be controlled by everyone if they think about the future. If we take care of mother earth and the resources, she will take care of us. Thank you!

Short Speech on Water Pollution

Good morning everyone! Today I want to talk about water pollution, its causes and how it can be controlled. A human body could survive without food for three days but it cannot survive without water for a day. It has been used by a living organism for ages. Life without water cannot be imagined. Water is the most important element that cannot be replaced by any other element. Due to the continuous use and exploitation, there is water pollution occurring all around us. 

Water pollution is considered a major issue in India as many people die in India because of unknowingly drinking polluted water. The condition of water pollution is so bad in India that every year 1.5 million children die from malaria. 

The reasons for water pollution in India are oil leaks, poor sanitization, No proper waste, and sewage treatment, and open defecation are considered to be the leading cause of water pollution in India. Children drink this contaminated water that causes a major bacterial attack on the digestive system, which results in diseases like diarrhea, etc. 

Water pollution could be controlled if needed precautions are taken. It is the responsibility of the government to come with new scientific methods for handling domestic sewage and garbage. 

The harmful industrial effluents should be neutralized and properly before discharging into water bodies.

To conclude this speech, I want to say that water pollution could be controlled if necessary measures are taken by everyone. Humans have exploited the resources provided by the Earth for a very long time and the result of that exploitation is various pollutions like water, air, etc. As a responsible human being, who wants a better future for the coming generation takes care of your surroundings. Do not throw garbage near water bodies and report anyone who does. Things last forever if we take care of them. Thank you.

4. What are the main causes of Water Pollution?

Water pollution When dangerous substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, the water quality deteriorates and the water becomes toxic to humans or the environment. Some freshwater systems supply clean drinking water as a vital ecosystem function, however due to pollution, roughly 785 million people throughout the globe do not have access to safe drinking water.

Main causes of Water Pollution includes:

a. Domestic sewage: Plant nutrients, mostly nitrates and phosphates, are abundant in sewage. Excess nitrates and phosphates in water encourage algae development, resulting in algal blooms, which are extremely dense and fast growths.

b. Toxic waste: Toxic waste is poisonous, radioactive, explosive, carcinogenic, and or bioaccumulative, which increases in concentration at the higher ends of food chains.

c. Sediment: Surface runoff can carry sediment (e.g., silt) into water bodies as a result of soil erosion.

Other reasons could include oil spillage. Oil spill is currently one of the leading causes of water pollution.

Water companies in England face outrage over record sewage discharges

Call for environmental emergency to be declared after data reveals 105% rise in raw sewage discharges over past 12 months

• How polluted is your local river and which regions are worst hit?

Water companies in England have faced a barrage of criticism as data revealed raw sewage was discharged for more than 3.6m hours into rivers and seas last year in a 105% increase on the previous 12 months.

The scale of the discharges of untreated waste made 2023 the worst year for storm water pollution. Early data seen by the Guardian put the scale of discharges at more than 4m hours, but officials said the figures were an early estimate.

The Liberal Democrat leader, Ed Davey, said the scandal of raw sewage pouring into waterways should be declared a national environmental emergency. He called on the government to convene an urgent meeting of the Scientific Advisory Group for Emergencies (Sage) to look at the impact of sewage pollution on people’s health.

Total discharges from the 14,000 storm overflows owned by English water companies that release untreated sewage into rivers and coastal waters increased by 54% to 464,056, according to data submitted to the Environment Agency by the industry.

Senior industry figures highlighted the heavy rainfall over the autumn and winter that put huge pressure on the sewerage system. But storm overflows are supposed to cope with heavy rainfall and only be used in exceptional circumstances, like major storm events. Climate change has long been predicted to bring higher rainfall levels.

One senior executive told the Guardian: “We have wasted 15 years, we have not been investing enough.”

The data on discharges from storm overflows reveals the duration and the number of discharges from individual overflows across the network in England. The 3.6m-plus hours of raw sewage and rainwater discharged over the year includes huge spikes in some outflows. Forty per cent of South West Water outflows discharged raw sewage more than 40 times, while nearly a third of United Utilities outflows and 23% owned by Yorkshire Water discharged 60 times or more.

Any outflow that has more than 60 discharges a year should prompt an Environment Agency investigation.

As well as total discharges soaring from just over 301,000 in 2022, the average discharge per storm overflow has increased to 33, an increase of more than 43.7%. Some companies had much higher average spills per outflow, with South West Water averaging 43 per outflow and United Utilities 45.

Some of the highest rises in the hours of raw sewage pouring into rivers were by Anglian Water, with a 205% increase to 273,163 hours, Wessex Water a 186% increase to 372,341 hours, Thames Water a 163% increase to 196,414 hours, and Northumbrian Water a 160% increase to 280,029 hours.

Severn Trent discharged raw sewage into waterways for 440,446 hours, South West Water for 530,737 hours, an 82.5% increase, Southern Water for 317,285, a 116% rise, and United Utilities for 656,014 hours, a 54% increase.

Thames Water was responsible for the biggest increase in the number of discharges, with its overflows dumping on 16,990 occasions, a 112% increase on 2022.

A Guardian analysis of the data revealed the River Irwell and its tributary, the Croal, which flows through to Salford and Manchester, had the highest levels of sewage spills. Nearby storm overflows spilled just under 12,000 times in 2023, or 95 spills per mile of water, the highest rate of all rivers in England .

Second worst in England was the River Darwen, near Blackburn and Preston, where there were more than 3,000 sewage spills from nearby overflows in 2023 – equivalent to 83 spills per mile. Just one river in the south of England features in the worst 10: the River Avon, as it makes its way through Bath and Bristol. This urban section of the river had 6,573 sewage spills in 2023, or 74 spills per mile, making it the third most polluted in England.

Also top of the list for sewage spills was the River Calder near Huddersfield, the Aire near Bradford and the lower section of the Tyne around Newcastle and Sunderland, the Guardian’s analysis of Environment Agency data found.

Criticism was not reserved for the industry. The government’s much vaunted plan to tackle raw sewage pollution gives water companies a deadline of 2035 to reduce the amount of sewage flowing into bathing water and areas of ecological importance, but discharges would continue being released into other waterways until 2050, at a time when the climate crisis is increasing rainfall intensity and frequency, putting more strain on the sewerage system.

Davey said the scandal had to be treated as an environmental national emergency. He said: “Only by treating the sewage scandal with the urgency it demands can we save our rivers and beaches for future generations to enjoy. Rishi Sunak and the Conservative party have failed to listen and as a result sewage spills are increasing, our precious countryside is being destroyed and swimmers are falling sick.”

The record sewage discharges were revealed as a major investigation into illegal sewage dumping by the regulator Ofwat into more than 2,000 treatment plants was nearing its conclusion. The Environment Agency is running a parallel criminal inquiry into illegal sewage dumping by companies.

after newsletter promotion

Storm overflows are supposed to be used only in extreme weather but for many years they have been used routinely, discharging raw sewage even on dry days in some cases. The academic Peter Hammond has shown how water companies are routinely using storm overflow discharges in their water management.

Campaigners turned their ire on the industry as the scale of the discharges was published. Ash Smith, who has investigated sewage pollution in the River Windrush for several years, said: “Water companies will blame the weather but it’s very clear from the data analysis done by Prof Peter Hammond that many sewage-dumping – we refuse to call this spilling – events are illegal either because sewage works simply don’t treat the amount they are required to or they do it in dry conditions.

“This is the information that needs to be made public along with volume, not just hours.”

Only two water companies, Southern and Thames Water , publish real-time data on raw sewage releases from outflows. Smith said greater transparency was needed. “How the other companies have been allowed to get away with keeping easily provided data public is a mystery. It is compounded by the secretary of state’s silence on getting them to reveal what will undoubtedly be a scandalous state of affairs.”

The shadow environment secretary, Steve Reed, said the government should immediately impose his plan for a ban on bonuses for water company executives. “Despite being responsible for this illegal behaviour, water company bosses have brazenly awarded themselves over £25m in bonuses and incentives since the last election,” said Reed.

Labour has not committed to any restructuring of the privatised water industry, even as Thames Water, which is struggling with debts of more than £14bn, is facing being taken into special administration. The Liberal Democrats are calling for Thames, the biggest of the privatised companies, to be put into special administration and turned into a public benefit company.

The Environment Agency director of water, Helen Wakeham, appeared to play down the scale of the increased pollution, saying it was not surprising that the discharges had increased. “We are pleased to see record investment from the water sector, but we know it will take time for this to be reflected in spill data – it is a complex issue that won’t be solved overnight.”

The water minister, Robbie Moore, said: “Today’s data shows water companies must go further and faster to tackle storm overflows and clean up our precious waterways. We will be ensuring the Environment Agency closely scrutinise these findings and take enforcement action where necessary.”

The revelation of the scale of releases into waterways comes as rivers in England are at crisis point, suffering from a toxic cocktail of raw and treated sewage pollution, chemical toxins and agricultural runoff.

In the last few weeks, ministers have engaged in a flurry of announcements in anticipation of the shocking data on record sewage spills. These included an announcement of a £180m plan to fast-track action on sewage discharges, in the face of criticism not enough is being done.

The industry is planning a record £96bn to the end of the decade to tackle sewage discharges, leaks and the impending water supply crisis but has been criticised for passing on the costs to customers for investment that should have been carried out years ago.

Water UK, which represents the industry, said: “These results are unacceptable and demonstrate exactly why we urgently need regulatory approval to upgrade our system so it can better cope with the weather. We have a plan to sort this out by tripling investment which will cut spills by 40% by 2030 – more than double the government’s target.”

Ofwat has to decide whether to allow companies to increase water bills to pay for the investment. Water UK said the investment was vital and Ofwat must give the industry the green light to get on with it.
