Around 12% of the pollution is caused by maritime transport.In South America, 98% of domestic wastewater ends up, untreated, in the sea. The countries along the Mediterranean Sea throw 50 million tons of waste into it every year and the Chinese throw 60 million tons of waste into the Yellow sea daily. Over half of the hydrocarbon discharge comes from continents, 5% comes from oil tanker accidents, 20% comes from waste and other ship-related accidents, 4% from sea exploitation and 11 to 15% is due to natural causes. Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year. In 2023, according to the WWF, between 0.7 and 1.3 million tons of oil were spread by degassing in the Mediterranean. According to the Ifremer (the French Institute for Exploitation of the Sea), coastal water pollution cost the world economy almost 12.8 billion dollars in 2023.Marine pollution is the result of products being thrown into seas and oceans, mostly by mnkind: domestic waste (sewage and rubbish, pollutants in runoff water...), industrial waste (hydrocarbons, metals, synthetic chemical and organic substances, radionuclides...) and agricultural waste (fertilisers, pesticides...).This includes water pollution and marine sediments, and more generally all damage to marine ecosystems caused by harmful substances being discharged into the sea, either by their nature or their quantity.。

海洋污染英语演讲稿Ladies and gentlemen,Today, I stand before you to address a pressing concern that affects not only our oceans but also the well-being of our planet – ocean pollution. Ocean pollution, caused by human activities, is a global problem that demands immediate attention and collective action. It threatens the delicate balance of marine ecosystems, harms marine life, and ultimately affects the livelihoods of millions of people who depend on the oceans for their sustenance and survival.First and foremost, let us understand the various sources of ocean pollution. The disposal of plastic waste is one of the major contributors to this issue. According to recent studies, approximately eight million tons of plastic waste end up in our oceans every year. This plastic waste not only visibly damages and pollutes our beaches and shorelines but also poses a significant threat to marine life. Sea turtles, for example, often mistake plastic bags for jellyfish and ingest them, leading to their death. Additionally, industries and ships are major sources of chemical pollutants, such as oil spills, heavy metals, and toxins, which contaminate the water and pose severe threats to marine flora and fauna.Furthermore, the consequences of ocean pollution are devastating. Overfishing, driven by unsustainable fishingpractices, disrupts the delicate balance of marine ecosystems and threatens the survival of various fish species. Coral reefs, known as the rainforests of the seas, face extinction due to the increasing acidification of the water caused by pollution. This not only affects the colorful marine life that depends on coral reefs but also disrupts the coastal protection they provide against storms and tsunamis. Moreover, the polluted waters can lead to an imbalance in the oxygen levels, resulting in widespread death of marine life and creating dead zones where no life can survive.Additionally, promoting sustainable fishing practices and regulating the fishing industry can help restore the balance of marine ecosystems. Protecting and conserving endangered species and their habitats, such as coral reefs and mangroves, iscritical to maintaining the diversity and resilience of our oceans. We must also invest in innovative solutions, such as developing biodegradable alternatives to plastic and promoting the use of clean energy sources in industries and ships.Finally, individuals can contribute to the fight against ocean pollution through simple daily actions. For instance, using reusable shopping bags, reducing single-use plastics, properly disposing of waste, and participating in coastal clean-up activities can make a significant impact on reducing ocean pollution.In conclusion, ocean pollution is a global crisis that demands immediate action from all stakeholders. It threatens marine life, disrupts ecosystems, and affects the livelihoods of millions of people. By raising awareness, implementing strict regulations, promoting sustainable practices, and taking individual actions, we can all play a role in preserving our oceans for future generations. Let us join hands and work together to protect our oceans and ensure a sustainable future for all. Thank you.。

海洋污染高三英语作文1Several problems are caused by the non-organic substance. We ought not to pour wastes into the ocean, because it not only pollutes the ocean, but also lead to a series of harmful consequence.First and foremost, the non-organnic things, for instance, plastic bags, may kill fish and whales.Second, fishes cant digest them.Finally, some of the rubbish is inherently toxic, they will posion marine life.We must take actions to protect our whale from dying. One thing we should do is creating a better system of disposing of rubbish.Another effective solution is making ships environmentally friendly. Sypermarkets shall stop the giving of plastic bags.As a captain of the ship, you should spare no efforts to think more helpful ideas and stop dumping rubbish from now on.We all need to raise awareness of these problems. It now bees necessary that we must act now, before it is too late!The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.In fact over 80% of all marine pollution es from land-based activities and many pollutants are deposited in estuaries and coastal waters.Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels.It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains.A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.Sea pollution is being an increasing problem for our planet and we have a responsibility to reduce sea pollution.I need to describe the problem. Our ship currently dumps all its rubbish into the sea.Its easy to result in huge endanger.First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance.We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly.A case in point is that we should stop providing plastic bags.We must act now before it is too late!海洋污染高三英语作文2From the overall situation, wastewater emissions growth speed. Is expected in 2000 will reach 666 tons. City life sewage volume will continue to increase, in 2000 reached about 783 tons. The wastewater of low (estimated at 20% 30%),most of untreated wastewater directly or indirectly discharged into the water body, the serious pollution of water resources. Chinas seven major river systems in nearly half of serious pollution, city section of river water qualitygenerally exceed the standard 86%. The polluted water, more serious is the Huaihe, Haihe, Liaohe, Songhua River, the downstream Yangtze River and the Pearl River Delta industries in developed region.River city section of riverpollution, heavy on the river, north to south. In 1990, 94 river city section of evaluation, 65 are subject to different degrees of pollution, accounting for 69.1%, the main pollutants ammonia nitrogen, volatile phenol and oxygen consumption of organic matter. According to the survey, 700000000 peopledrinking water the Escherichi a coli exceed the standard, 164000000 people drink organic pollution of water, 35000000 people nitrate drinking water exceed the standard.Huaihe is one of the most polluted rivers. Huaihe in the evaluation of the 2000kilometers of the river, 78.7% river does not meet the drinking water standard,the 79.7% section does not meet the standard of fishery water, 32% do not meet the standard of irrigation water. According to statistics, the national 3000 heavily polluting enterprises, enterprises of wastewater discharge of industrial pollution,Huaihe River Basin accounts for 160. A sewage units 1.55 182 towns within the basin, industrial wastewater emissions of 1610000000 cubic meters, 700000000 cubic meters of urban living water emissions. Huaihe sewage irrigation farmland,causing serious crop production; in 1989 the occasion of the Spring Festival, the sewage discharge upstream gate opening, the tap water in Huainan, Bengbu twocity is seriously polluted and not drinking, Huaihe basin, the public drinking watercrisis, people Voices of discontent.Huaihe basin in many areas of cancer incidence rate than the normal area than 10 times to hundreds of times, some villages in 2/3 of hepatomegaly. At the same time, due to the pollution of the estuary, anadromous fish resources has been damaged, the sharp drop in output, part of the inner bay fisheries basic abandoned.The widespread contamination of lakes, especially the heavy metal pollution and eutrophication problem is very conspicuous. For example, Dianchi is Kunmings largest source of drinking water, water supply for the water supply of 54%, due to the area around Kunming city and Dianchi a large number of industrial and domestic sewage discharge, resulting in Dianchi heavy metal pollution and eutrophication is very serious, as a source of drinking water for a number ofindex is unqualified, overgrown with algae, summer and autumn 84% water by algae coverage. In 1993 Third Waterworks in Kunming city have been forced to stop production for 43 days, a direct economic loss of about 40000000 yuan; themany rural well water also can not drink, resulting in about 300000 rural drinking water difficulty. Because of drinking contaminated water, poisoning incidents have occurred; Dianchi specialty whitebait substantially reduction of output,reduce fish species, rare species disappeared.Bohai is China inland sea, has been seriously polluted. In the waters of Bohai,reducing the number of marine organisms, fish, shellfish, endangered, has bee almost no life "the dead sea". The coastal seawater transparencydecreased significantly, reddish brown or black. Some aquatic products, are on the brink of extinction. On the contrary, fish, green oyster with oil odor (copperpollution), rotten spot kelp has appeared in large numbers. Due to consumption of contaminated seafood and sick of people more and more.Water is limited, water is precious, water is not renewable. In the face of such apainful lesson, every man on the earth, to consciously establish water-saving awareness, tighten the taps, save every drop of water, reduce and prevent water pollution to human. Water pollution is the civilization of pollution, is the era ofpollution; water disappear is the national disappear, is human extinction.海洋污染高三英语作文3Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including plex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the worlds 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,Marine living resources are likely to cause more damage.The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat, in particular, their migration, spawning, foraging, avoiding predators coast, tidal flats, estuaries, coral reefs, it is necessary to prevent the heavy metals, pesticides, oil, organic and easy to produce nutrients such as eutrophication of marine pollution. Preservation of the marine living resources of the natural regeneration capacity and water purification capacity, preservation of the marine ecological balance, to ensure sustainable human development and utilization of the oceans.海洋污染高三英语作文4Several problems are caused by the non-organic substance.

第1篇Ladies and Gentlemen,Good morning/afternoon/evening. It is an honor to stand before you today to discuss a critical issue that affects us all: water pollution. Water is the lifeblood of our planet, and without it, life as we know it would cease to exist. However, the reality is that our precious water resources are under threat like never before. In this speech, I will highlight the causes, consequences, and solutions to water pollution, and I will urge each and every one of you to take action.Firstly, let us explore the causes of water pollution. There are several factors contributing to this alarming problem. Industrial activities are a significant source of water pollution. Factories and manufacturing plants often discharge untreated or poorly treated wastewater into rivers, lakes, and oceans, contaminating the water with hazardous chemicals and heavy metals. Agriculture is another culprit, as the excessive use of fertilizers and pesticides leads to runoff thatpollutes nearby water bodies. Additionally, improper waste management, including the dumping of garbage and plastics into waterways, further exacerbates the problem.The consequences of water pollution are far-reaching and devastating. It affects not only human health but also the health of our ecosystems. Contaminated water can lead to waterborne diseases such as cholera, dysentery, and hepatitis, which can be fatal, especially in vulnerable populations like children and the elderly. Moreover, the pollution of aquatic habitats can lead to the decline of fish populations and other aquatic life, disrupting the food chain and affecting biodiversity. In some cases, entire ecosystems can collapse due to the accumulation of pollutants.Economically, water pollution has significant repercussions. It can lead to the closure of fisheries and aquaculture industries, impacting the livelihoods of millions of people who depend on these sectors for their income. Additionally, the treatment of polluted water requiressubstantial resources, which can be a financial burden on governments and communities.So, what can be done to address this pressing issue? Firstly, we need to implement stricter regulations and enforcement measures to control industrial and agricultural pollution. Governments must ensure that factories and farms adhere to stringent standards for waste treatment and disposal. This may involve investing in advanced technologies and incentivizing the adoption of sustainable practices.Secondly, we must promote awareness and education on the importance of clean water and the role we all play in protecting it. By educating children and adults alike, we can foster a culture of responsibility and encourage individuals to make environmentally conscious choices, such as reducing water usage and disposing of waste properly.Furthermore, we need to invest in infrastructure improvements, such as upgrading sanitation systems and promoting the use of renewable energy sources. This will not only reduce pollution but also create jobs and contribute to sustainable development.Lastly, international cooperation is crucial. Water pollution does not recognize national boundaries, and therefore, we must work together to tackle this global challenge. This includes sharing best practices, providing financial assistance to developing countries, and enforcing international agreements on environmental protection.Ladies and gentlemen, the time for action is now. Water pollution is a ticking time bomb that threatens our future. It is up to each and every one of us to take responsibility and contribute to the solution. Whether we are individuals, businesses, or governments, we have a role to playin protecting our most precious resource.Let us remember that clean water is a fundamental human right. It is essential for our health, our economy, and our very existence. By taking immediate and decisive action, we can ensure that future generations inherit a world where water is not just abundant but also clean and safe.In conclusion, I urge you to join me in this fight against water pollution. Let us work together to implement sustainable practices, promote education, and advocate for stricter regulations. Together, we can make a difference and secure a brighter, healthier future for all.Thank you.第2篇Ladies and Gentlemen,Good morning/afternoon/evening. It is an honor to stand before you today to address a topic that affects us all – water pollution. Water is the essence of life, and it is crucial that we take immediate and decisive action to protect this precious resource. In this speech, I will highlight the severity of water pollution, its causes, and the consequences it poses to our planet and society. Finally, I will propose some solutions and call for a collective effort to combat this pressing issue.Firstly, let us acknowledge the magnitude of water pollution. According to the World Health Organization, approximately 1.1 billion people lack access to safe drinking water, and 2.4 billion people lack access to improved sanitation facilities. These statistics paint a grim picture of the current state of our water resources. Water pollution is not a localized issue; it is a global crisis that affects every continent and every community.The causes of water pollution are multifaceted and interconnected. Industrial activities, agricultural runoff, improper waste disposal, and urban development are some of the primary contributors. Industries often release toxic chemicals, heavy metals, and other pollutants into water bodies, leading to the contamination of aquatic ecosystems. Similarly, agricultural practices, such as the excessive use of fertilizers and pesticides, result in nutrient and chemical runoff that disrupts water quality and affects aquatic life. Moreover, improper waste disposal, including the dumping of plastics and other non-biodegradable materials, poses a significant threat to marine life and coastal ecosystems.The consequences of water pollution are far-reaching and devastating. It not only endangers human health but also threatens the survival of countless species. Contaminated water can lead to waterborne diseases, such as cholera, dysentery, and typhoid fever, which disproportionately affect the most vulnerable populations, including children and the elderly. Additionally, the pollution of aquatic ecosystems disrupts the balance of nature, leading to the decline of fish populations, loss of biodiversity, and the degradation of habitats.The economic impact of water pollution is also significant. The cost of treating contaminated water and addressing waterborne diseases is enormous. Moreover, the loss of livelihoods due to the destruction of aquatic ecosystems and the decline in fisheries and aquaculture can have severe economic consequences for communities that depend on these resources.To address this crisis, we must adopt a multi-pronged approach that encompasses prevention, mitigation, and restoration. Here are some solutions that we can implement:1. Strengthening regulations and enforcing existing environmental lawsis essential. Governments should impose strict regulations on industrial activities and agricultural practices to minimize pollution. Moreover, regular monitoring and auditing of water bodies should be conducted to ensure compliance.2. Promoting sustainable agricultural practices, such as integrated pest management and precision farming, can reduce the use of harmful chemicals and minimize runoff. Encouraging organic farming and the use of natural fertilizers can also contribute to cleaner water.3. Improving waste management systems is crucial. Communities should invest in proper waste disposal facilities and promote recycling and composting programs. The reduction of plastic use and the promotion of biodegradable materials can also help mitigate the pollution of water bodies.4. Investing in research and development of new technologies for water treatment and purification can significantly improve water quality. Innovations in desalination, filtration, and purification methods can make contaminated water safe for consumption and irrigation.5. Educating and raising awareness among the public about the importance of water conservation and pollution prevention is vital. Encouraging responsible behavior and promoting sustainable lifestyles can lead to a collective effort to protect our water resources.In conclusion, water pollution is a critical issue that requires immediate attention and concerted action. By implementing the solutions proposed in this speech, we can make significant strides towardsrestoring and preserving our water resources for future generations. Let us join hands, commit to responsible stewardship, and work together to ensure that our planet's lifeblood remains clean and accessible for all.Thank you for your attention, and I invite you to join me in this callto action. Together, we can make a difference and safeguard the futureof our planet.[End of speech]第3篇Good morning/afternoon/evening. It is my great honor to stand before you today to address a critical issue that affects us all – water pollution. Water is life; it sustains us, nourishes us, and provides us with the means to thrive. However, the state of our water bodies today is amatter of grave concern. Therefore, I implore you to join me inreflecting upon the causes, consequences, and potential solutions tothis global crisis.Water pollution is the contamination of water bodies, such as rivers, lakes, oceans, and groundwater, with harmful substances. The sources of water pollution are myriad, but they can generally be categorized into two main types: point source pollution and non-point source pollution.Point source pollution refers to pollution that originates from a single identifiable source, such as an industrial discharge pipe or a wastewater treatment plant. These sources are relatively easy to regulate, but they can still cause significant harm to the environment and human health. For instance, industrial chemicals, heavy metals, and oil spills are common contributors to point source pollution.On the other hand, non-point source pollution is more challenging to control, as it comes from numerous, diffuse sources. This includes agricultural runoff, urban stormwater, and even atmospheric deposition. Non-point source pollution can lead to the degradation of water quality, affecting both aquatic ecosystems and human communities.The consequences of water pollution are far-reaching and devastating. Firstly, it poses a severe threat to aquatic life. Polluted water bodies can lead to the death of fish, birds, and other marine creatures, disrupting the delicate balance of ecosystems. Secondly, it endangers human health. Contaminated water can cause diseases such as cholera, typhoid, and hepatitis, leading to malnutrition and even death in vulnerable populations. Moreover, the pollution of drinking watersources can lead to chronic health issues, including cancer and neurological disorders.In addition to the health risks, water pollution has significant economic implications. It can damage industries that rely on clean water, such as fisheries, tourism, and agriculture. The loss of biodiversityand ecosystem services due to water pollution can also have long-term economic consequences for communities and nations.So, what can we do to combat this crisis? The first step is to raise awareness about the importance of clean water and the dangers of pollution. Education is key in fostering a culture of environmental responsibility and ensuring that individuals and communities take action.Secondly, governments and regulatory bodies must implement strictpolicies and regulations to control and reduce pollution. This includes enforcing stricter emissions standards for industries, investing insustainable agricultural practices, and improving the efficiency of wastewater treatment plants.Furthermore, technological advancements can play a pivotal role in mitigating water pollution. Innovations in water treatment technologies, such as advanced oxidation processes and membrane filtration, can help remove pollutants from water bodies. Additionally, the development of green infrastructure, such as rain gardens and permeable pavements, can reduce non-point source pollution.We must also promote sustainable consumption patterns and lifestyles. This involves reducing our reliance on single-use plastics, minimizing the use of harmful chemicals in everyday products, and adopting more sustainable agricultural practices.Lastly, international cooperation is essential in addressing the global nature of water pollution. Countries must work together to share knowledge, resources, and best practices in order to tackle this shared challenge.In conclusion, water pollution is a multifaceted issue that requires a comprehensive and collaborative approach. By raising awareness, implementing strict regulations, embracing technological advancements, promoting sustainable lifestyles, and fostering international cooperation, we can take significant steps towards preserving our most precious resource – clean water.Thank you for your attention. Let us all commit to protecting our water bodies for the sake of our future generations. Together, we can make a difference.[The end of the speech]。
