海洋污染的英語演講稿 1
Know you today from the 2009, let me do a return tour, you tour in 2030 with the "Ocean", I think you must be harvested. As we all know, oceans of the Earths seven tenths, very serious marine pollution in 2009, but in 2030, due to advanced science and technology, "decontamination robot" has become the bane of marine pollution, so, when there is no pollution in the ocean. Now, I take you first "multi-functional reception", and replace "changes in the marine location device", it all took us off to another world. Todays oceans, is home to human beings, 50 percent of people worldwide live in the ocean, you will find it very curious about how to survive in the ocean? Fact Well, Sea World, where there is an "oxygen control room," Oxygen produced from here, through the "oxygen cylinder" sent to every corner of Ocean, people breathing in fresh oxygen, emit carbon dioxide, and then by the "oxygen control room" to receive, but also to create such a cycle of oxygen ……
Harbour fish is strange, since the sea water into fresh water, the fish learned human language, but also to talk with people it can be fun! You to the front of a large group of fish, fish said: "Good morning!" Fish will speak English, I am really not believe it. Listen to my introduction to you on the residential areas. Although before you see is a blank, but people live here. The sea and land were not the same person, they food is simple, a "simple food Dan" can be over 100 days, so they are very relaxed. Live it? To four "sea" as their home, think of where to sleep on where to sleep, carefree.
Then, you visit the Royal Palace, Park …… must have felt very grand, magnificent it! Perhaps you worry about, so many people living in the seabed, the environment will not occur the problem? Not. Harbour achieved without factory, but there are production. And no worse than the production of the land, because we row down the waste land, water, through the "decontamination robot" "pass" "make the robot" for processing, making available all kinds of things ... ... strange, wonderful sea world tour finished, how? I am sure you will feel the power of science is so magical.

Pollution in the ocean is a major problem that is affecting the ocean and the rest of the Earth, too. Pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. Oil spills, toxic wastes, and dumping of other harmful materials are all major sources of pollution in the ocean. People should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution.
What are toxic wastes?
Toxic wastes are poisonous materials that are being dumped into the ocean. They harm many plants and animals in the ocean and have a huge impact on our health. Toxic waste is the most harmful form of pollution to sea life and humans. When toxic waste harms an organism, it can quickly be passed along the food chain and may eventually end up being our seafood. In the food chain, one toxic organism gets eaten by another, larger animal, which gets eaten by another animal, and can end up being our seafood. Toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. Farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans.
Many fishermen believe that the toxic chemicals in the ocean are killing much of the fish population. One of the most harmful chemicals in the ocean is lead. Lead can cause many health problems. It can damage the brain, kidneys, and reproductive system. Lead can also cause birth defects for people. It has been shown to cause low IQ scores, slow growth, and hearing problems for small children. House and car paint and manufacturing lead batteries, fishing lures, certain parts of bullets, some ceramic ware, water pipes, and fixtures all give off lead.
Many things found in the ocean may cause seafood to be dangerous to human health. The effect on humans from contaminated seafood may include birth defects and nervous system damage. Medical waste found in the ocean is being tested to see if swimmers have a chance of developing Hepatitis or AIDS. Other waste has been known to cause viral and bacterial diseases. This type of pollution can be stopped by watching what pollution we are letting into the ocean. People are trying to decrease the amount of waste in the oceans by recycling as much garbage as they can so there is a smaller amount of very harmful materials in the ocean.
Boating Pollution Prevention Tips
Whenever someone takes their boat onto the water for a ride, it is creating pollution that can be very harmful to the sea life. Boating pollution is the pollution that comes from the boat’s engine when it is running, and it pollutes the water, killing animals with the chemicals in the exhaust from the engine. The engine gives off excess gasoline, which pollutes the waters and ends up killing the animals. In order to make as little pollution as possible, what everyone can do to help is:
Only turn a boat engine on all the way when you need to.
Don’t take your boat out into the water if you don’t need to.
Be sure to store and transport gasoline in places where there isn’t any direct sunlight because the gasoline will evaporate, and all of the gases that have been evaporated will pollute the air.
Every year, buy new or cleaner marine engines for your boats.
Garbage Dumping
Garbage dumping is the dumping of harmful materials into the ocean like human waste, ground-up garbage, water from bathing, and plastics. Most of the waste that has been dumped into the ocean in the early 1990’s is still there today. One main cause of garbage dumping occurs when sewage pipes share their space with storm water drains. Rainfall causes the sewage pipes to overflow and the sewage waste mixes with the storm water drain, which flows into another water source such as a lake or river. After that, the garbage pollutes the ocean, kills plants and animals in the water (for example, the plastic rings that are around pop cans can get around an animal’s neck, causing it to suffocate), and makes the water dirty.

Between 75 and 80% of marine pollution is caused by land, particularly agriculture. 30% of this is from the atmosphere. 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 2003, 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 2015.
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.

The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical,biological,and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems.
Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies.Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day,mostly in developing countries.
Many people are not aware that water pollution is serious problem in almost all parts of the world,and not just in third world countries like some choose to believe.In fact many experts will tell you that reality is completely different than the common belief,and that actually water pollution problem is already out of control.
Water pollution problem is in most cases connected with the careless handling of chemical agents,toxins introduced into our water through industrial dumping,and farm runoff.All these factors make our water unsafe to drink.
For instance,the chlorine that is widely used to disinfect our water is believed by many to be carcinogenic,and therefore a major health issue that significantly contributed to worldwide rise of cancer rates.
Basically chlorine is present in every glass of water we draw from our tap,and although some studies have confirmed that chlorine can indeed be one of the cancer risk factors we simply cannot do without it because by removing chlorine from our water we would open the door to many waterborne diseases that would kill millions of people around the globe.
So how to protect yourself from water pollution?The best option available to us is to install a multi-layered home water filtering system in your home.The best option is multi media block system that has an activated granular carbon filter,a sub micron filter,and an ion exchange.This system is capable to prevent up to 99.99% of all of the harmful contaminants present in our water from entering your home.
High quality home water filtering system is really your best ally against water pollution.

Several 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 becomes necessary that we must act now, before it is too late!

Sea pollution is becoming 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!

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 comes 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.

Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex 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.

Ladies and Gentlemen:
Good morning！
Today, I stand before you to discuss a pressing issue that impacts our planet in profound and far-reaching ways: marine pollution. The oceans, which cover over 70% of Earths surface and are vital for our survival, are facing an unprecedented crisis due to human activities.
Marine pollution is the introduction of harmful substances or energy into the ocean, which can damage marine life, habitats, and human health. This contamination can be divided into several categories: plastic pollution, chemical pollution, oil spills, and sewage discharge, among others.
Plastic pollution is perhaps the most visible and concerning form. Every year, millions of tons of plastic waste enter our oceans, harming marine wildlife that often mistake it for food or get entangled in it. This debris not only affects sea creatures directly but also enters the human food chain through the ingestion of contaminated fish and seafood.
Chemical pollution, including heavy metals, pesticides, and industrial waste, poses another significant threat. These chemicals can disrupt marine ecosystems, bioaccumulate in organisms, and ultimately reach human consumers. The long-term health effects of these contaminants are still being studied but are already alarming.
Oil spills, whether from tanker accidents, drilling operations, or intentional releases, cause catastrophic damage to marine environments. Oil covers the surface of the water, preventing oxygen exchange, which can lead to massive fish kills and the destruction of entire ecosystems. The lingering oil residues can also persist in the environment for years, continuing to harm wildlife.
Sewage discharge, particularly from untreated or partially treated municipal and industrial wastewater, introduces pathogens, nutrients, and other pollutants into coastal waters. This can lead to algae blooms that deplete oxygen levels, causing fish kills and harming other marine life.
The impacts of marine pollution are severe and multifaceted. They range from the loss of biodiversity and the disruption of food chains to economic losses for fisheries and tourism industries. Moreover, the health of coastal communities is compromised when they rely on contaminated seafood or are exposed to polluted beach environments.
Addressing marine pollution requires a multi-faceted approach involving governments, businesses, and individuals. Policies must be implemented to reduce plastic use, improve waste management, and regulate industrial activities. Businesses should adopt sustainable practices and invest in green technologies. As consumers, we can reduce our plastic footprint, support eco-friendly products, and participate in beach clean-ups.
Education and awareness campaigns are crucial in changing behaviors and fostering a culture of responsibility towards our oceans. By understanding the interconnectedness of our actions and their impacts on marine environments, we can inspire collective action and drive change.
In conclusion, marine pollution is a complex and urgent challenge that demands our immediate attention and sustained effort. The health of our oceans is directly linked to the health of our planet and ourselves. Let us unite in our commitment to protect and restore these vital blue spaces for future generations.
Thank you.

Ladies and Gentlemen:
Good morning!
Today, I stand before you to address a pressing issue that affects not just our oceans, but the entire planet—marine pollution. Our oceans, covering over 70% of the Earths surface, are vital for life on this planet. They regulate our climate, produce oxygen, and are home to an incredible diversity of marine life. However, human activities have turned these vast blue waters into a dumping ground for waste, threatening the health of our oceans and, consequently, our own well-being.
The Sources of Marine Pollution
Marine pollution stems from various sources. Plastic waste is perhaps the most visible and infamous culprit. Every year, millions of tons of plastic enter our oceans, harming marine wildlife and disrupting ecosystems. Single-use plastics, such as straws, bags, and bottles, often end up in the stomachs of marine animals, causing starvation, poisoning, and even death.
In addition to plastics, oil spills from tankers and drilling activities pose a significant threat. These spills can cover vast areas, smothering marine life and contaminating habitats. Chemical pollutants, including heavy metals and persistent organic pollutants (POPs), also find their way into our oceans, often through runoff from agricultural and industrial activities.
The Impact on Marine Life and Human Health
The impact of marine pollution on marine life is devastating. Ingestion of plastic and other pollutants can lead to physical harm and bioaccumulation of toxins in the food chain. This not only affects marine species but also amplifies the risk for humans who consume seafood.
Moreover, marine pollution disrupts the delicate balance of marine ecosystems. Coral reefs, often referred to as the "rainforests of the sea," are particularly vulnerable. Pollutants can bleach corals, leading to their death and the collapse of entire ecosystems that rely on them.
The human health implications are also profound. Consumption of contaminated seafood can lead to a range of health problems, including cancer, reproductive issues, and nervous system damage.
Solutions and Actions
Addressing marine pollution requires concerted global effort. Governments must enforce stricter regulations on plastic production and disposal, promote sustainable fishing practices, and invest in clean-up initiatives. Industries must adopt environmentally friendly practices and take responsibility for their waste.
Individuals can also play a crucial role. Reducing our use of single-use plastics, supporting companies with sustainable practices, and participating in beach clean-ups are all actions we can take to mitigate marine pollution.
Education and awareness are key. By raising public awareness about the impacts of marine pollution and encouraging sustainable consumption habits, we can foster a culture of environmental stewardship.
Conclusion
In conclusion, marine pollution is a critical issue that demands immediate and sustained action. Our oceans are the lifeblood of our planet, and their health is directly linked to our own. By working together, we can protect these vital blue waters, preserve marine biodiversity, and ensure a healthy and sustainable future for all.
Thank you for your attention. Let us all commit to taking action against marine pollution and safeguarding our oceans for generations to come.

Ladies and Gentlemen:
Good afternoon,Today, I stand before you to discuss a pressing issue that affects not just our oceans, but the very fabric of life on Earth: marine pollution. Our oceans cover over 70% of the planets surface and are home to an incredible diversity of marine life. They regulate our climate, produce oxygen, and are a vital source of food and livelihoods for millions of people around the globe. Yet, these vast and majestic bodies of water are under siege from pollution, threatening their health and, by extension, our own.
The Extent of the Problem
Marine pollution encompasses a wide range of contaminants, from plastic waste and oil spills to chemical discharges and noise pollution. Each year, millions of tons of plastic enter our oceans, where they break down into microplastics that are ingested by marine organisms, disrupting their ecosystems and potentially entering the human food chain. Oil spills, whether from tanker accidents or intentional discharges, coat seabirds and marine mammals in toxic sludge, suffocate marine life, and contaminate habitats. Chemical pollutants, including heavy metals and persistent organic pollutants (POPs), bioaccumulate in the food chain, causing reproductive and developmental problems in marine species and potentially harming human health.
Impact on Marine Life
The impacts of marine pollution on marine life are devastating. Sea turtles mistake plastic bags for jellyfish and ingest them, leading to starvation and death. Dolphins and whales are found entangled in fishing nets, suffering excruciating pain and often dying a slow death. Coral reefs, often referred to as the "rainforests of the sea," are bleaching and dying due to ocean acidification caused by increased carbon dioxide levels and pollution. This loss of biodiversity not only devastates marine ecosystems but also undermines the economic and social well-being of coastal communities that depend on the oceans for their livelihoods.
Human Health Implications
The consequences of marine pollution extend far beyond the oceans. Consumption of contaminated seafood can lead to a range of health issues, including cancer, endocrine disruption, and neurotoxicity. Microplastics have been found in tap water, bottled water, and even beer, highlighting the pervasive nature of this pollution. Furthermore, the economic costs of marine pollution are staggering, impacting tourism, fisheries, and the broader economy.
Solutions and Action
Addressing marine pollution requires a multi-faceted approach involving governments, industry, and civil society. Governments must enforce stricter regulations on plastic production and disposal, promote sustainable fishing practices, and establish marine protected areas to safeguard critical habitats. Industries must adopt cleaner production methods, reduce waste, and take responsibility for the lifecycle of their products. Civil society, including NGOs, community groups, and individuals, can play a crucial role by advocating for policy change, participating in clean-up efforts, and reducing their own plastic footprint.
Education and awareness-raising are also vital. By informing the public about the impacts of marine pollution and encouraging behavior change, we can foster a culture of stewardship and responsibility towards our oceans.
Conclusion
In conclusion, marine pollution poses a grave threat to our oceans, marine life, and human health. It is a problem that demands urgent and concerted action from all sectors of society. As stewards of this planet, we have a moral and legal obligation to protect our oceans. Let us unite in our efforts to combat marine pollution, preserve the beauty and biodiversity of our oceans, and ensure a sustainable future for generations to come.
Thank you.
