Water pollution is a global threat that leads to deaths and diseases worldwide

I agree with the statement. Water pollution gives a threat to the marine animals and sea creatures.
Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater. All water pollution affects organisms and plants that live in these water bodies and in almost all cases the effect is damaging either to individual species and populations but also to the natural biological communities. It occurs when pollutants are discharged directly into water bodies without adequate treatment to remove harmful constituents.Many of the chemical substances are toxic, this causes the marine animals or sea creatures to take in the harmful toxic which causes them to die.Many causes of pollution including sewage and fertilizers contain nutrients such as nitrates and phosphates. In excess levels, nutrients over stimulate the growth of aquatic plants and algae. Excessive growth of these types of organisms consequently clogs our waterways, use up dissolved oxygen as they decompose, and block light to deeper waters.
This, in turn, proves very harmful to aquatic organisms as it affects the respiration ability or fish and other invertebrates that reside in water

Pollution is also caused when silt and other suspended solids, such as soil, washoff plowed fields, construction and logging sites, urban areas, and eroded river banks when it rains.Lead and cadmium can get into the water and will be absorbed by tiny creatures. These tiny creatures are consumed by your dinner. Eating certain seafood can cause serious health issues like hepatitis for humans. Chemical water pollution typically occurs because the chemicals were dumped into the water intentionally,the chemicals seeped into groundwater, streams, or rivers because of failing pipes or storage tanks,the chemicals catastrophically contaminated waterways because of industrial accidents,the pollution settled out of polluted air (or was precipitated out of polluted air); or chemicals were leached out of contaminated soil.
Pesticides are carried in rainwater runoff from farm fields, suburban lawns, or roadside embankments into the nearest creeks and streams. Occasionally they are even intentionally sprayed into waterways as part of a pest-control effort. Egad—talk about destroying the village to save it!Pesticides can migrate via water into the food chain as well, ultimately being consumed by humans or animals in food.
When oil pollution gets in water, some of the components of are degraded and dispersed by evaporation, photochemical reactions, or bacterial degradation, while others are more resistant and may persist for many years, especially in shallow waters with muddy sediments.
When rain or surface water flows over exposed rock and soil, it can combine with naturally occurring sulfur to form sulfuric acid. The acidified rainwater eventually finds its way to streams and groundwater, polluting them and impacting local aquatic life.
when animals take in any of the harmful substances they will die.some non-biodegradeble materials such as plastics and glass can remain in the ground forever, they will pollute the environment and damage the marine animals if they accidentally swallow it.

It is true that water pollution is a global threat as, if we human pollutes the water then the world's population will be in trouble because water is the most essential need of we human thus water will be a great global threat towarsd us. Water pollution lead to death and diseases as some bacteria are contianed in river water and the water that we drink, the bacteria comes from the water that we had polluted and the dirt from the pollution get afffected or fused wtih other bacteria and have different effect int he water to create new diseases thus there will be more death.

indeed water pollution is really endangering our lives, this is being caused by some irresponsible factories that charge waste gases and pollutants into the sea or ocean without andequate treatment to remove the harmful constituents.this can result in the death of marine lifes and might also cause extinction towards some marine animals if this goes on and whats more having water pollution will
also harm us directly or indirectly like getting on some diseases which are deadly and causes a result of death. if this goes on i personally thinks that there will be more deadly diseases being created like h1n1 and other disease if this really happens there will be more people dying. so i think those factories should try the treat all these pollutants before discharging it into the ocean so
as to save the marine lives and save ourselves.

i agree as polluting the oceans harms alot of marine life and we are also talking about saving animals from being extinct so we should not pollute the natural environment that they live in.if possible we should use mre air transport for things that spill easily like oil.oil blocks oxygen from entering the water and without oxygen.soon all the marine animals will run out of oxygen and die.

i agree with yuen sian's answer.Water pollution is a major problem in the global context. It has been suggested that it is the leading worldwide cause of deaths and diseases,and that it accounts for the deaths of more than 14,000 people daily.In addition to the acute problems of water pollution in developing countries, industrialized countries continue to struggle with pollution problems as well. In the most recent national report on water quality in the United States, 45 percent of assessed stream miles, 47 percent of assessed lake acres, and 32 percent of assessed bay and estuarine square miles were classified as polluted.

Water is typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use, like serving as drinking water, and/or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. Natural phenomena such as volcanoes, algae blooms, storms, and earthquakes also cause major changes in water quality and the ecological status of water.

other than water pollution which is harming us there are still some which is causing us harm and diseases e.g air pollution this is also doing a great harm to us as technology have been improving there are now vehicle which runs by engine convenient it may be but it produces a gas called carbon monoxide which when we breathe in it may harm us as this gas can causes harm to our lungs and whats has started doing this is Taiwan they have setup 8-12 branches of kiosk for people to rent bikes and ride to work instead of riding on vehicles which firstly harm ourselves and secondly harm Earth I think we should also be more responsible like Taiwan if they can i am sure we as a Singaporeans also can do it both water pollution and air pollution can really harm our lives so we should be more considerate.

factories which produce oil and other waste gases not only is bad for marine lives it is also bad for plants too as when oil covers the sea bed it blocks sunlight from reaching the plants from trapping sunlight to photosynthesize this could be a very bad news to the marine lives as for not photosynthesizing and producing dissolved oxygen the marine lives may not live to long and result in death this cloud add up another problem created by water pollution hence add another burden to the ones who are sincerely trying to reduce water pollution.

according to melvin's statement, i think that his ans is half true. researchers have been tryin to find way to make sure cars do not release as much carbon monoxide as before. there are new cars invented that runs on electricity nowadays and scientists are still tryin to find ways to make sure cars dont emit a high amount of carbon monoxide.

I'M THE KING

I definitely agree with yuxuan. Water pollution is a very big problem for us and fishes. It is causing many lives to be sacrificed. Factories that is producing items might give out harmful gases that’s bad for us. If the gases were to be very thick, it can cover the surface of the ocean and not let other gases enter the ocean like oxygen for the fishes. Other examples is ships carrying oil or unwanted stuffs suddenly banged into one another and all the items it carried might submerged into the sea. If the items were to carry poisonous items, the fishes that eat it will die so there will not be any ‘seafood’ for us as the fishes are contaminated. If the plants in the ocean don’t get enough carbon dioxide or sunlight to photosynthesize, the fishes also will die as most of them are fighting for food. People who are inconsiderate also sometimes throw thing into the ocean and pollute them. We too might die if we were to drink the harmful water.
The world is crying for help so please young world stop doing things that could hurt the ocean. We must not waste mankind.

i think that WaterPollution is a threat to all living beings.As water essential to all liveing things.Without water,plants would not be able to photosynthesis to make food,And when plants do not make food,there would nt hav a food chain,leading to deaths of organisms due to a lack of food.Also when we are thirsty,we would need to drink water and when the water is polluted,we would probably die after drinking the polluted water as it may be dirty.

Water is and essential items for living things. Without water, all living things die. So, water is very important to us as Egyptians relied on the Nile River for 3000 years!! Without water, there is no civilization. Without water there will be no culture no nothing!! But, water is getting polluted day by day... Lets see...

Looking at Haikal's answer I say the first one ''Water pollution is a very big problem for us and fishes. It is causing many lives to be sacrificed.'' Lives, are not sacrificed but killed.
As water get polluted and the government do not care, and people continue drinking the water and the fishes do not find other places to live. They all get KILLED by the polluted water, not sacrificed.

Second thing ''We too might die if we were to drink the harmful water.'' the ''harmful water'', is the ocean water so we do not drink the ocean water. If you see the post, you know.

Back to water pollution, I agree with Haikal's people throw rubbish or inconsiderate people throw rubbish into our oceans, rivers and seas. This acts, we are starting to pay as fishes die and plants die. Reducing the number of fishes and plants in the sea. And reducing number of fishes and plants = lesser seafood. So seafood will get lesser and lesser. So seafood get more and more expensive

Ships collide with other ship sometimes and oil may spill, once they spill, the creatures in the ocean will die as the layer of oil will block the sunlight and plants cannot photosynthesis. So there is more carbon dioxide in the ocean...

The Earth is dying because of our pollutions, so be considerate and not pollute water and not waste water!! lol.

i disagree with warren's post about the seafood because when there is lesser seafood due to water pollution,who will still dare to sell the dead,sick seafood,Eg.fishes Or should i say who will dare to EAt seafood sold So it willl not get expensive due to this issue but to extinct from the market So Start Cleaning Up the Earth ,Stop polluting So as to Get to eat seafood.^^

I agree with the statement.Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater. All water pollution affects organisms and plants that live in these water bodies and in almost all cases the effect is damaging either to individual species and populations but also to the natural biological communities. Water pollution is a major problem in the global context. It has been suggested that it is the leading worldwide cause of deaths and diseases and that it accounts for the deaths of more than 14,000 people daily.The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. Many of the chemical substances are toxic.Many different pollutants can harm our rivers, streams, lakes and oceans. The three most common are soil, nutrients and bacteria. Rain washes soil into streams and rivers. The soil can kill tiny animals and fish eggs. It can clog the gills of fish and block light so plants die. Nutrients, often from fertilizers, cause problems in lakes, ponds and reservoirs. Nitrogen and phosphorus make algae grow and can turn water green. Bacteria, often from sewage spills, can pollute fresh or salt water.

I disagree with what Jinjon disagrees with me.

Firstly, if you said that polluted oceans and people DARED not eat the seafood or buy it, then why do people still buy seafood? Im sure you have eat it. The oceans are now very polluted and i did not state that the pollution is in the future but now.

Secondly, there are still some parts in the world with clean ocean. Fishes that are free from sickness and illnesses. There are also fishes or seafood bred in enclosed environment which will keep them away from the pollution.

So, I still say that price will increase but the issue of extinction is not important. Get it? Lol.

Most water pollutants are carried by rivers into the oceans. The contamination of ground water, rivers, lakes, wetlands, estuaries, and oceans can threaten the health of humans and aquatic life. Sources of water pollution are generally divided into two categories. The first is point-source pollution, in which contaminants are discharged from a discrete location. Sewage outfalls and oil spills are examples of point-source pollution. The second category is non-point-source or diffuse pollution, referring to all of the other discharges that deliver contaminants to water bodies. Acid rain and unconfined runoff from agricultural or urban areas are examples of non-point-source pollution. The principal contaminants of water include toxic chemicals, nutrients and biodegradable organics, and bacterial and viral pathogens.Water pollution can threaten human health when pollutants enter the body via skin exposure or through the direct consumption of contaminated food or drinking water.

NOOOOOO now currently,the sea is not severely polluted right? thats why we still can Eat sea food.i AM refering to when the sea gets really polluted as what YOU said,until the whole sea is covered with dirt n oil, surely plants ,fishes,aquautic organisms will surely get the effect and when they take in the polluted water,they will surely die.Do You Think It is STILL POSSIBLE TO EAT THEM????????

i think jin jon's post is just half true because water pollution not only affect seafood(marine life) it also affects birds and mammals in the ocean like when there are oil spills , oil gets stuck to the feathers and fur of animals and thus making the fur and feathers less heat resistence , thus the animals gets to cold and freezes to death. When birds which fly with oil in their feathers , they might not be used to the strength needed to fly as they will get heavier because of the oil stuck to them and might fall from the sky due to tiredness or might even have not enough strength to take of from the ground and might even freeze to death espically for migratory birds. So we should prevent oil spills by maybe transporting goods by aeroplanes or create boats which is powered by bio-fuel which made from vegetables and if the oil spills , it MIGHT BE food for fishes. So save life on earth xD espically fishes(seafood) so when i go fishing can catch fish xD

i dissagree with warren (dun angry pls) . Extinction is a bigger problem than just PRICE or MONEY because when the marine life gets extinct , we will lose a big source food around the world. imagine a world without marine life and a world with just polluted waters. Many fish sellers will lose their jobs imagine how the people who depend on the fishes for food find food to survive!

Most fish are low in fat and cholesterol and a good source of protein, which makes them a good choice for a healthy diet. Our bodies require a certain amount of protein daily and the body does not store protein so we need to replenish it in our daily diet. All fish are a good source of B vitamins and oil-rich fish are a good source of vitamins A and D. Many fish also provide a good source for calcium.

Oil-rich fish, such as salmon, trout, mackerel, herring and sardines, are an excellent source of Omega-3 fatty acids, which are essential to our diet. Omega-3 fatty acids cannot be manufactured by the body so it is important that we bring them into our diet and eating oil-rich fish provides the Omega-3 fatty acids we need. Some of the benefits of the Omega-3 oil in fish are shown below.

.Reduces the risks of heart attacks.
.Makes the blood flow easier through the body, reducing blood pressure.
.It is felt that it helps the heart beat steadier and reduces the chances of suffering from a stroke.
.Omega-3 fatty acids can also help in development of the brain, nerves and eyesight.

Water polution occurs when pollutants is discharge into water bodies without any treatment to remove harmful constituent.
Eg,oil spillage.Plants could not photosynthesize because the oil on surface of water block sunlight from reaching the sea.Hence,they would die,affecting the food chain.Being primary producer of food chain,once plants are destroyed ,how do other animals get their food.
Beside plants taking in poisonous water,some waste such as plastic bag ,could also cause harm to animals.some animals may mistook the plastic bag as its prey and consume it.Soon after,they would be died.
From here, we can say that water polution will surely upset the biodiversity.

water polution harms the biodiversity it harms not only plants but also animals.So we should reduce water polution so to preserve the orgnisms not to let them extinct.Here is some way taken by people to reduce water polution:
Maintain your septic system. If you have a septic system, have it regularly inspected and maintained. Overloaded or improperly functioning septic systems can spew raw sewage directly into bodies of water or can contaminate groundwater. Most septic systems should be pumped every 2-3 years.
2.Most factories nowadays have proper discharge system so as to reduce the amount of harmful chemicals release to the sea.

i disagree with clement disagreeing with warren disagreeing with jin jon disagreeing with his own post(i know its abit confusing but i got no choice) as extinction is only a species of fish gone from the world and that i know the issue where they were saying seafood prices will increase but here am i telling IT WILL NOT because it is only 1 species gone unlike what clement said that a food source will be gone.when a species go extinct, the prey of that species will grow rapidly due to its predator is extinct and therefore this is enough to replace the loss of that 1 food source so there will be seafood for everyone to eat again .If the ocean was to be polluted as they were saying, there will be a lackage of food and water but it will not as the water of the ocean is already undrinkable so where do we get our water then...FROM THE RESERVOIRS LAH :lol!:and the second point about the food, if there are no more seafood in the world, what will all of us eat eat other food !!! its not like the world has run out of food and will all starve to death.clement also stated that if there are no more fishes, we will not have omega-3 which is essential for us and so i am saying again its not like the world does not have any other food that contain omega-3.And there is this very easy solution on how to save marine life DONT EAT ANY SEAFOOD!!!(like as if you can resist it)

i am agreeing with the topic as is a pollution was to occur, then the world will be greatly affected as there will be lesser seafood for everyone to eat and there will be insufficient water for the world as the amount of fresh water in the world is only about 3% and if we lose even this small source of drinkable water, there will surely be a lack of water for the world so therefore water pollution is a global threat as it threatens the life of people by lack of water and also spreading of diseases and we should prevent it so lets start saving the ocean!!!

I agree with Hui Shan ,pollution is not only caused by soapy water and other stuff but also by soil etc., .
Water can be caused by sewage or waste water,marine ,even global warming,industrial waste,oil pollution,radioactive waste,underground storage leakages.atmospheric deposition and last but not least eutrophication.

What is eutrophication???

Eutrophication is when the environment becomes enriched with nutrients. This can be a problem in marine habitats such as lakes as it can cause algal blooms.Fertilisers are often used in farming, sometimes these fertilisers run-off into nearby water causing an increase in nutrient levels. This causes phytoplankton to grow and reproduce more rapidly, resulting in algal blooms. This bloom of algae disrupts normal ecosystem functioning and causes many problems. The algae may use up all the oxygen in the water, leaving none for other marine life. This results in the death of many aquatic organisms such as fish, which need the oxygen in the water to live. The bloom of algae may also block sunlight from photosynthetic marine plants under the water surface. Some algae even produce toxins that are harmful to higher forms of life. This can cause problems along the food chain and affect any animal that feeds on them.
