Pollution is the contamination of the environment by introduction of contaminants that can cause damage to environment and harm or discomfort to humans or other living species. It is the addition of another form of any substance or form of energy to the environment at a rate faster than the environment can accommodate it by dispersion, breakdown, recycling, or storage in some harmless form.

Environmental pollution is one the greatest challenges that the world is facing today. It began since industrial revolution, increasing day by day and causing irreparable damage to Mother Earth. Environmental pollution has its own causes, effects and solutions. Looking into these will help you identify the causes and what steps you can take to mitigate those effects. Broadly, environmental pollution consists of six basic types of pollution, i.e. air, water, land, soil, noise, and light.

When people think of environmental pollution, most focus on fossil fuel and carbon emissions, but there are different contributing factors. Chemical pollution in bodies of water contributes to illnesses. Electromagnetic pollution has effects on human health but is uncommonly considered in present times despite the fact we essentially expose ourselves to it on a daily basis. Taking a look at causes and effects of environmental pollution will pull any mind on a rapid downward spiral. Solutions are in the works and, if we work together across the world, there is hope remaining, at least for the time being.

The environment will continue to deteriorate until pollution practices are abandoned.
~ B. F. Skinner

Causes of Environmental Pollution

Pollution from cars, trucks, and other vehicles is and has been our major environmental pollution issue for almost a century now. The problem is we did not realize this until the problem had manifested to monumental proportions.

Fossil fuel emissions from power plants which burn coal as fuel contributed heavily, along with vehicles burning fossil fuels, to the production of smog. Smog is the result of fossil fuel combustion combined with sunlight and heat. The result is a toxic gas which now surrounds our once pristine planet. This is known as "ozone smog" and means we have more problems down here than we do in the sky.

Carbon dioxide is another product from all of the vehicles on the planet as well as unreformed power plants and other industrial facilities. A continually growing population of humans and clear cutting of forests has exacerbated this problem so natural defenses are no longer present and carbon dioxide levels are on the rise.

Water pollution is a major issue. Many industries dump wastes into rivers, lakes, ponds, and streams in an attempt to hide wastes from EPA inspectors. These water sources feed major crops and food becomes contaminated with a variety of chemicals and bacteria, causing rampant health problems.

Radiation comes into play as well. This is an exceedingly nasty pollution issue and requires extensive description. Primarily, there is radiation from the sun. As the natural ozone layer around the Earth has become depleted. The sun is wonderful, but the only reason we are able to survive on this planet so close to the sun is due to the fact of natural shielding against solar radiation. As the protective ozone layer around the planet has become thinner, ultraviolet radiation has risen significantly, causing increases in skin cancers and other types of cancer in all countries, killing millions of people every year.

More radiation is a problem. The sun shining brightly on a naked planet is not the only source of radiation we are exposed to. Electromagnetic radiation is another insidious culprit. Once upon a time, the major concern around this type of radiation was due to high tension wires which carry huge amounts of electricity to cities. Now, we even carry sources of this radiation with us as cell phones, laptops, tablets and other wireless devices.

Effects of Environmental Pollution

The polluting gases mentioned above have an interesting effect on climate. Essentially, these gases form a veil around the planet which holds heat in, increasing the overall temperature of the planet. The rise in planetary temperature, or global warming, is not immediately noticeable. However, even a rise of a few degrees Centigrade causes catastrophic changes in weather. This is happening now.

Pollen has increased. It is ironic, but even with fewer trees in the world; the increase of carbon dioxide emissions induces plants such as ragweed and many trees to produce more pollen than ever before. This has resulted in rampant allergies across the world, affecting the health of billions of people.

One of the solutions to tamp out carbon monoxide emissions from coal burning power plants was and still is to use radioactive power plants. While this does cut down on gas emissions significantly, there is radioactive waste which causes various cancers to bloom in major cities and small towns all around while destroying ecosystems entirely.

Global temperature has risen significantly over the years. The protective atmosphere is further being polluted by methane gas released from melting icecaps. This is causing rampant weather issues around the planet.

This all seems like a fairly bleak outlook for the planet and all the creatures on it. It is, in fact, a load of dark and very real truth. For much of it, there is little turning back. Being realistic, though solutions are in the works to combat global warming, the hope is dim. Radiation does not go away quickly either, especially in a technological age requiring more power, more gas, and intensified depletion of protective gases around the planet. We are on a significant downhill snowball ride to hell. There are things we can do. Let us take a look at some of the solutions which are currently being implemented to reduce pollution.

Solutions to Environmental Pollution

Gas emission pollution is being mitigated in a variety of ways with car emission control, electric and hybrid vehicles and public transportation systems. Not all major cities have successful implementation and decent public transportation in place, but the world is working on this issue constantly and we have managed to reduce emissions profoundly over the last decade. There is much catching up to do.

The cost of radioactive power plants is becoming apparent and the days of coal power plants are nearly dead. The radiation is a serious issue. Radioactive leakage from power plants and nuclear testing have already contaminated oceanic life to such a degree that it will take hundreds of years to return to normal. More radiation solutions are in the works with various ecologically friendly power technologies being built every day.

Solar power is a fantastic solution. Now that solar radiation is at a climactic peak, we can reap power from the sun using solar panel systems. These range from home systems to larger scale systems powering entire communities and cities.

Wind power is coming into play. This may not seem like much at first, but when you get about 100 feet off the ground, there is a great deal of wind up there. By building wind turbines to harvest natural wind energy, electricity is produced. Wind turbine power and solar power are both powerful forces against fossil fuel power and radioactive power. The one problem here is power companies. They want to stay with radioactive power plants because they actually can't be removed. It has become the crusades of many individuals and small corporations to make the switch and there are plenty of people following this as populations cry out for help.

Electromagnetic radiation (ER) reduction. Once major manufacturers of computers and electronic devices realized the blatant potential for huge ER emissions directly into the eyes and brains of users, they started to implement hardware protocols to minimize risks and reduce ER production significantly. Newer devices are in the lead to knock this problem out and, fortunately, this is working.

Also, the Environmental Protection Agency (EPA) is well aware of all leaks and tricks industries are using to dump wastes. This agency now has extremely strict protocols and testing procedures implemented against such facilities so populations are not affected. Additionally, the EPA is measuring air pollution and implementing regulatory procedures for vehicle emissions. They also monitor pollen issues and, with the help of the Centers for Disease Control (CDC), they implement solutions to reduce pollen in the air.

Dropping pollen counts is a major focus for EPA and CDC activities. Asthma and other allergic conditions are flooding medical care facilities and pharmaceutical companies with serious public health problems. The response has been swift and various methods to control emissions and reduce pollen counts are in the works. Children and elderly people are at the highest risk for environmental pollution related health problems. The good news is we are directly on the horizon to cut down the causes and risks while providing practical health solutions for the general public throughout the world.

Natural Causes of Water Pollution
Sometimes water pollution can occur through natural causes like volcanoes[not in Singapore:], algae blooms, animal waste, and silt from storms and floods.
What happens for animals is that
A sea turtle swims through the water and spots a white blob floating near the surface. “Yum!” it thinks. “A jellyfish!” Chasing after its dinner, the turtle swallows the item. But the floating blob isn’t a jelly—it’s a plastic bag that could make the sea turtle sick.

This sea creature isn’t alone: Over 700 species of marine animals have been reported to have eaten or been entangled in plastic. Scientists think that the amount of plastic in the ocean might triple by 2050—and that would mean seriously bad news for the ocean and the creatures that live there. But by understanding the issue and taking action, you can help stop that from happening. Humans may not get clean water too

:1) Heavy metals from industrial processes are dumped in nearby lakes and rivers and caused water pollution. Water pollution occurs when water is contaminated by substances from humans and other wastes. This basically means that water pollution had started from all of the trash we put in the water.                                                    2) How it affects humans: Infectious diseases can be spread through contaminated water. Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. Chemicals also have negative effects on our health.                       How it affects animals: Pollution in the water can reach a point where there isn't enough oxygen in the water for the fish to breathe and the fish and up DEAD :D

# data[].attributes.body
Water pollution is the contamination of water bodies (like oceans, seas, lakes, rivers, aquifers, and groundwater) usually caused due to human activities. Water pollution is any change in the physical, chemical or biological properties of water that will have a detrimental consequence of any living organism.

Cause

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil and therefore contaminate groundwater.

In the same way, the pesticides used in agricultural fields filter through underground channels and reach the consumption networks; And also as a result of accidental spillage of oil.

Effect

What are the main consequences of water pollution? Firstly, the disappearance of biodiversity and aquatic ecosystems. Also, humans are harmed by the alteration in the food chain and by contracting illnesses when drinking or using contaminated water. As you can see, water pollution has a great impact in the environment.

.Industrial Wastes

Industrial and manufacturing wastes are the biggest causal agents of water pollution. The manufacturing and industrial process mostly releases scores of chemical compounds and waste products that end up in waters. This include:

1. Sulfur: Industries emit gaseous waste of sulfur dioxide which then chemically reacts with water molecules and oxygen in the atmosphere to form sulfuric acid. The sulfuric acid is then discharged into water bodies as precipitation to form acidic lakes/oceans. Likewise, dry sulfur compound depositions generated from industrial gasses and waste processes frequently deposits in water bodies.

2. Heavy metals: Lead and mercury are examples of some of the heavy metallic substances that normally find a way to water bodies. Heavy metals reach water bodies via stormwater runoff carrying dry exhaust depositions, industrial/consumer wastes, or mine drainage from mining activities. This is common phenomena in industrial, urban, and metal ore mining/processing areas or dumping sites adjacent to water bodies.

3. Nitrates & Phosphates: Fertilizers contain high levels of nitrates and phosphates and are frequently washed from farmlands adjacent to water bodies. They can cause eutrophication, which can severely damage aquatic environments.

4. Detergents, hydrocarbons, and other chemical compounds: Detergents, solvents, petroleum hydrocarbons, chlorinated solvents, disinfectants, food processing wastes, and other chemical waste byproducts from industries are as well water contaminants that commonly end up in water sources.

2. Oil Spill

Oil is a major water pollutant. Routine shipping, sea port operations, and oil refining at the seas have led to water pollution through oil dumping and spillage. Once the oil spills in the water, it makes a thick layer on the surface of the water as it is insoluble in water. As a result, oil spills can extensively harm and kill a marine life because it cuts the supply of dissolved oxygen and prevents light from penetrating into the water.

Dissolve oxygen is essential for the survival of aquatic organisms and sunlight is a requisite for photosynthesis. A good example is the 2012 BP oil spill that killed thousands of marine animal species like birds, fish, turtles, and sea otters. About 12% of oil spills is from the oil that enters the ocean.

3. Sewage and Waste Water

On a daily basis, sewages and wastewater are discharged into surface waters. Everyday human activities demand laundry, use of the toilet, and taking shower among other domestic water uses. All these necessities finally lead to waste and sewage water.

In developed worlds, the water is channeled through a sewer system to a central waste water collection point where the water is cleaned and treated then discharged into water bodies such as rivers, lakes, and oceans. As much as the water is treated and cleaned, it cannot be the same as fresh water.

In some developing worlds with poor waste water management systems, waste water, and sewages are not treated or cleaned. They are directly discharged into the sea or water bodies. As a result, it contaminates water bodies and threatens the survival of aquatic life or results to spread of waterborne diseases.

4. Lake, Ocean, and Marine Dumping

People sometimes dump material waste into water resources including rivers, lakes, canals, and oceans. Examples include food waste, paper waste, rubber, glass, metallic, and plastic waste. Depositing these foreign materials into the water leads to water pollution as they have the capacity to make physical and chemical changes to the water such as discoloration or temperature changes.

Dumping of material wastes into water also modifies some of the naturally occurring chemical and substances. For example, paper waste deposited into the water can take about 6 weeks to decompose. Other substances like aluminum take up to 200 years to decompose, and glass materials can take more than 200 years. When these materials are dumped into the waters, they cause extensive changes that in the long run ruin and even kill aquatic life forms.

5. Underground Storage and Leakages

There are cases whereby chemicals among other products or materials are stored underground. A classical example is liquid petroleum products stored in underground metal or steel tanks. Likewise, some sewer systems are channeled through underground tubes whereas underground pipelines are used to ferry liquids and gaseous chemical products.

After some period, the tanks, tubes and pipelines can begin leak due to rusting or cracks caused by tectonic movements. When this happens, the leakages contaminate the soils and gradually seep to neighboring waters or end up in aquifers that lead to ground water pollution.

6. Pesticides and Fertilizers: Farmers use pesticides and fertilizers to protect their plants from insects and bacterias. These chemicals when mixed up with water cause water pollution and pose serious effects to aquatic ecosystems as they flow down through rivers and lakes to oceans.

7. Leaking Landfills: A landfill site is a site for disposal of waste material by burial. They are not designed to break down trash, merely to bury it. When it rains, the leaking water from landfills filled with toxic contaminants may pollute the underground water.

8. Animal Waste: Animal waste is yet another source of water pollution. When it rains, the waste produced by animals is flown down through rivers and canals to oceans where it gets mixed up with other harmful chemicals. These toxic contaminants may cause serious effects on human health.

Also, most domestic home toilet wastes are predominantly emptied into underground septic tanks. In the septic tank, biological processes break down the liquid materials from the solids. From this point, the liquid material seeps into the ground to adjacent waters or end up in aquifers thereby causing ground water pollution.

1.Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases.

Water pollution can be classified as surface water or groundwater pollution. Marine pollution and nutrient pollution are subsets of water pollution. Sources of water pollution are either point sources or non-point sources. Point sources have one identifiable cause of the pollution, such as a storm drain or a wastewater treatment plant. Non-point sources are more diffuse, such as agricultural runoff.[3] Pollution is the result of the cumulative effect over time. All plants and organisms living in or being exposed to polluted water bodies can be impacted. The effects can damage individual species and impact the natural biological communities they are part of.

The causes of water pollution include a wide range of chemicals and pathogens as well as physical parameters. Contaminants may include organic and inorganic substances. Elevated temperatures can also lead to polluted water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. Elevated water temperatures decrease oxygen levels, which can kill fish and alter food chain composition, reduce species biodiversity, and foster invasion by new thermophilic species.

Water pollution is measured by analysing water samples. Physical, chemical and biological tests can be conducted. Control of water pollution requires appropriate infrastructure and management plans. The infrastructure may include wastewater treatment plants. Sewage treatment plants and industrial wastewater treatment plants are usually required to protect water bodies from untreated wastewater. Agricultural wastewater treatment for farms, and erosion control at construction sites can also help prevent water pollution. Nature-based solutions are another approach to prevent water pollution. Effective control of urban runoff includes reducing speed and quantity of flow. In the United States, best management practices for water pollution include approaches to reduce the quantity of water and improve water quality.i copy this from wikipedia.

What is water pollution?

Water pollution is when waste, chemicals, or other particles cause a body of water (i.e. rivers, oceans, lakes) to become harmful to the fish and animals that need the water to survive. Water pollution can disrupt and negatively impact nature's water cycle as well.

Natural Causes of Water Pollution

Sometimes water pollution can occur through natural causes like volcanoes, algae blooms, animal waste, and silt from storms and floods.

Human Causes of Water Pollution

A lot of water pollution comes from human activity. Some human causes include sewage, pesticides and fertilizers from farms, waste water and chemicals from factories, silt from construction sites, and trash from people littering.
Oil Spills

Some of the most famous incidents of water pollution have been oil spills. One was the Exxon Valdez oil spill which occurred when an oil tanker hit a reef off the coast of Alaska and over 11 million gallons of oil spilled into the ocean. Another bad oil spill was the Deepwater Horizon oil spill when an explosion at an oil well caused over 200 million gallons to spill into the Gulf of Mexico.

Acid Rain

Air pollution can also have a direct effect on water pollution. When particles like sulfur dioxide get high into the air they can combine with rain to produce acid rain. Acid rain can turn lakes acidic, killing fishes and other animals.

Effects on the Environment

Water pollution can have disastrous effects on the environment.

Pollution in the water can reach a point where there isn't enough oxygen in the water for the fish to breathe. The fish can actually suffocate!

Sometimes pollution affects the entire food chain. Small fishes absorb pollutants, such as chemicals, into their bodies. Then bigger fishes eat the smaller fishes and get the pollutants too. Birds or other animals may eat the bigger fishes and be harmed by the pollutants. One example of this was the use of the insecticide (bug killer) DDT. When birds of prey ate fishes that were infected with it, they would lay eggs with thin shells. The population of birds of prey began to drop until DDT was banished.

Sewage can also cause major problems in rivers. Bacteria in the water will use oxygen to break down the sewage. If there is too much sewage, the bacteria could use up so much oxygen that there won't be enough left for the fish.

Water pollution from major events like acid rain or oil spills can completely destroy marine habitats.

Effects on Health

One of the most precious and important commodities for life on planet Earth is clean water. For over 1 billion people on the planet, clean water is nearly impossible to get. Dirty, polluted water can make them sick and is especially tough on young children. Some bacteria and pathogens in water can make people so sick they can die.

Types of Water Pollutants

There are many sources of water pollution. Here are a few of the major causes:

Sewage - Even today sewage is flushed directly into streams and rivers in many areas around the world. Sewage can introduce harmful bacteria that can make people and animals very sick.

Farm animal waste - Waste from large herds of farm animals such as pigs and cows can get into the water supply from the runoff of rain and large storms.

Pesticides and herbicides - Pesticides are often sprayed on crops to kill bugs and herbicides are sprayed to kill weeds. These strong chemicals can get into the water through runoff of rain storms. They can also contaminate rivers and lakes through accidental spills.

Construction, floods, and storms - Silt from construction, earthquakes, floods, and storms can lower the oxygen content in the water and suffocate fish.

Factories - Factories often use a lot of water to process chemicals, keep engines cool, and for washing things away. The used waste water is sometimes dumped into rivers or the ocean. It can be full of pollutants.What can you do to help?

Save water - Fresh and clean water is a precious resource. Don't waste it! Take shorter showers, ask your parents not to water the lawn, make sure the toilet isn't running, and don't leave the faucet running.

Don't use weed killer - Ask your parents if you can pull the weeds in the yard so they don't need to use weed killer (an herbicide).

Scrape your plates clean into the trash and don't put grease into the kitchen drain.

Trash - Always pick up your trash, especially when at the beach, lake, or river.

What is Water Pollution?

The water they say is life, and indeed they were right. With about 70% of the earth’s cover being water, it undeniably becomes one of our greatest resources. As young students, we learned about the various ways to conserve water; coming to think of it, water is used in almost every important human chores and processes. It is an important element in both domestic as well as industrial purposes. However, a closer inspection of our water resources today, give us a rude shock.

Infested with waste ranging from floating plastic bags to chemical waste, our water bodies have turned into a pool of poison. In simple words, the contamination of water bodies means water pollution. Thereby the abuse of lakes, ponds, oceans, rivers, reservoirs, etc is water pollution. Pollution of water occurs when substances that will modify the water in a negative fashion are discharged in it. This discharge of pollutants can be direct as well as indirect.

Save

Water pollution is an appalling problem, powerful enough to lead the world on a path of destruction. Water is an easy solvent, enabling most pollutants to dissolve in it easily and contaminate it. The most basic effect of water pollution is directly suffered by the organisms and vegetation that survive in water, including amphibians. On a human level, several people die each day due to consumption of polluted and infected water.

As per the Economist report (dated 2008) each day over 1000 children die of diarrheal sickness in India and the numbers have only increased alarming in the last five years. Water is polluted by both natural as well as man-made activities. Volcanic eruptions, earthquakes, Tsunamis, etc are known to alter water and contaminate it, also affecting ecosystems that survive under water.

Various Sources of Water Pollution

There are various classifications of water pollution. The two chief sources of water pollution can be seen as Point and Non-Point.

Point refers to the pollutants that belong to a single source. An example of this would be emissions from factories into the water.

Non-Point, on the other hand, means pollutants emitted from multiple sources. Contaminated water after rains that has traveled through several regions may also be considered as a Non-point source of pollution.

Various Causes of Water Pollution

1. Industrial waste

Industries produce a huge amount of waste which contains toxic chemicals and pollutants which can cause air pollution and damage to us and our environment. They contain pollutants such as lead, mercury, sulfur, asbestos, nitrates, and many other harmful chemicals.

Many industries do not have a proper waste management system and drain the waste in the fresh water which goes into rivers, canals and later into the sea. The toxic chemicals have the capability to change the color of water, increase the number of minerals, also known as eutrophication, change the temperature of water and pose a serious hazard to water organisms.

2. Sewage and wastewater

The sewage and wastewater that is produced by each household is chemically treated and released into the sea with fresh water. The sewage water carries harmful bacteria and chemicals that can cause serious health problems. Pathogens are known as a common water pollutant; The sewers of cities house several pathogens and thereby diseases.

Microorganisms in water are known to be causes of some very deadly diseases and become the breeding grounds for other creatures that act as carriers. These carriers inflict these diseases via various forms of contact onto an individual. A very common example of this process would be Malaria.

3. Mining activities

Mining is the process of crushing the rock and extracting coal and other minerals from underground. These elements when extracted in the raw form contains harmful chemicals and can increase the number of toxic elements when mixed up with water which may result in health problems. Mining activities emit a large amount of metal waste and sulphides from the rocks which is harmful to the water.

4. Marine dumping

The garbage produced by each household in the form of paper, aluminum, rubber, glass, plastic, food is collected and deposited into the sea in some countries. These items take from 2 weeks to 200 years to decompose. When such items enter the sea, they not only cause water pollution but also harm animals in the sea.

5. Accidental oil leakage

Oil spill poses a huge concern as a large amount of oil enters into the sea and does not dissolve with water; thereby opens problem for local marine wildlife such as fish, birds and sea otters. For e.g.: a ship carrying a large quantity of oil may spill oil if met with an accident and can cause varying damage to species in the ocean depending on the quantity of oil spill, size of the ocean, the toxicity of pollutant.

6. The burning of fossil fuels

Fossil fuels like coal and oil when burnt produce a substantial amount of ash in the atmosphere. The particles which contain toxic chemicals when mixed with water vapor result in acid rain. Also, carbon dioxide is released from the burning of fossil fuels which result in global warming.

7. Chemical fertilizers and pesticides

Chemical fertilizers and pesticides are used by farmers to protect crops from insects and bacterias. They are useful for the plant’s growth. However, when these chemicals are mixed up with water produce harmful for plants and animals. Also, when it rains, the chemicals mix up with rainwater and flow down into rivers and canals which pose serious damages for aquatic animals.

Save

8. Leakage from sewer lines

A small leakage from the sewer lines can contaminate the underground water and make it unfit for the people to drink. Also, when not repaired on time, the leaking water can come on to the surface and become a breeding ground for insects and mosquitoes.

9. Global warming

An increase in earth’s temperature due to the greenhouse effect results in global warming. It increases the water temperature and results in the death of aquatic animals and marine species which later results in water pollution.

10. Radioactive waste

Nuclear energy is produced using nuclear fission or fusion. The element that is used in the production of nuclear energy is Uranium which is a highly toxic chemical. The nuclear waste that is produced by radioactive material needs to be disposed of to prevent any nuclear accident. Nuclear waste can have serious environmental hazards if not disposed of properly. Few major accidents have already taken place in Russia and Japan.

11. Urban development

As the population has grown, so has the demand for housing, food, and cloth. As more cities and towns are developed, they have resulted in increasing use of fertilizers to produce more food, soil erosion due to deforestation, increase in construction activities, inadequate sewer collection, and treatment, landfills as more garbage is produced, increase in chemicals from industries to produce more materials.

12. Leakage from the landfills

Landfills are nothing but a huge pile of garbage that produces the awful smell and can be seen across the city. When it rains, the landfills may leak and the leaking landfills can pollute the underground water with a large variety of contaminants.

13. Animal waste

The waste produced by animals is washed away into the rivers when it rains. It gets mixed up with other harmful chemicals and causes various water-borne diseases like cholera, diarrhea, jaundice, dysentery and typhoid.

14. Underground storage leakage

Transportation of coal and other petroleum products through underground pipes is well known. Accidentals leakage may happen anytime and may cause damage to the environment and result in soil erosion.

Water pollutants also include both organic and inorganic factors. Organic factors include volatile organic compounds, fuels, waste from trees, plants etc.  Inorganic factors include ammonia, chemical waste from factories, discarded cosmetics etc. The water that travels via fields is usually contaminated with all forms of waste inclusive of fertilizers that it swept along the way. This infected water makes its way to our water bodies and sometimes to the seas endangering the flora, fauna and humans that use it along its path.

The current scenario has led to a consciousness about water preservation and efforts are being made on several levels to redeem our water resources. Industries and factory set-up’s are restricted from contaminating the water bodies and are advised to treat their contaminated waste through filtration methods. People are investing in rainwater harvesting projects to collect rainwater and preserve it in wells below ground level.

Water Pollution is common, and is an area of high alert. Water needs to be preserved and respected today, for us to live a tomorrow.

Water pollution is one the main environmental issues that we are facing, as more than 70% of the Earth’s surface is water-covered.Unsurprisingly, human activity is primarily responsible for water pollution, even if natural phenomenon - such as landslides and floods - can also contribute to degrade the water quality.Water pollution can be defined as the contamination of a stream, river, lake, ocean or any other stretch of water, depleting water quality and making it toxic for the environment and humans.

Water pollution truly harms biodiversity and aquatic ecosystems. The toxic chemicals can change the color of water and increase the amount of minerals - also known as eutrophication - which has a bad impact on life in water. Thermal pollution, defined by a rise in the temperature of water bodies, contributes to global warming and causes serious hazard to water organisms.                            Water pollution has very negative effects on public health. A lot of diseases result from drinking or being in contact with contaminated water, such as diarrhea, cholera, typhoid, dysentery or skin infections. In zones where there is no available drinking water, the main risk is dehydration obviously.There are two types of water pollution:

1.Organic pollution due to microorganisms - bacteria and viruses - present in the water, generated by excrement, animal and vegetable waste

2.Chemical pollution generated by the nitrates and phosphates of pesticides, human and animal 🤬, household products, heavy metals, acids and hydrocarbons used in industries.
SEWAGE AND WASTEWATER
Inadequate sewage collection and treatment are sources of water pollution. According to the United Nations, more than 80% of the worldwide wastewater goes back in the environment without being treated or reused.

URBANIZATION AND DEFORESTATION

Even though it does not have a direct impact on water quality, urbanization and deforestation have a lot of indirect effects. For instance, cutting down trees and concreting over large areas generates an acceleration of flows which does not give enough time for water to infiltrate and be purified by the ground.

AGRICULTURE

Agriculture has an impact on water pollution due to the use of chemicals such as fertilizers, pesticides, fungicides, herbicides or insecticides running off in the water, as well as livestock excrement, manure and methane (greenhouse effect). Regarding aquaculture, pollution is directly in the water, as excess food and fertilizers are causing dystrophication.
INDUSTRIES
Industries produce a lot of waste containing toxic chemicals and pollutants. A huge amount of the industrial waste is drained in the fresh water which then flows into canals, rivers and eventually in the sea. Another source of water pollution is the burning of fossil fuels, causing air pollution like acid rain which then flows to streams, lakes, and other stretches of water.

MARINE DUMPING

Everyday, garbage such as plastic, paper, aluminum, food, glass, or rubber are deposited into the sea. These items take weeks to hundreds of years to decompose, and thus they are a major cause for water pollution.

RADIOACTIVE WASTE

Generated - among others - by power plants and uranium mining, radioactive waste can linger in the environment for thousands of years. When these substances are released accidentally or disposed improperly, they threaten groundwater, surface water, as well as marine resources.Water pollution has very negative effects on public health. A lot of diseases result from drinking or being in contact with contaminated water, such as diarrhea, cholera, typhoid, dysentery or skin infections. In zones where there is no available drinking water, the main risk is dehydration obviously.

Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases.[1][2]

Water pollution can be classified as surface water or groundwater pollution. Marine pollution and nutrient pollution are subsets of water pollution. Sources of water pollution are either point sources or non-point sources. Point sources have one identifiable cause of the pollution, such as a storm drain or a wastewater treatment plant. Non-point sources are more diffuse, such as agricultural runoff.[3] Pollution is the result of the cumulative effect over time. All plants and organisms living in or being exposed to polluted water bodies can be impacted. The effects can damage individual species and impact the natural biological communities they are part of.

The causes of water pollution include a wide range of chemicals and pathogens as well as physical parameters. Contaminants may include organic and inorganic substances. Elevated temperatures can also lead to polluted water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. Elevated water temperatures decrease oxygen levels, which can kill fish and alter food chain composition, reduce species biodiversity, and foster invasion by new thermophilic species.[4][5]:375

Water pollution is measured by analysing water samples. Physical, chemical and biological tests can be conducted. Control of water pollution requires appropriate infrastructure and management plans. The infrastructure may include wastewater treatment plants. Sewage treatment plants and industrial wastewater treatment plants are usually required to protect water bodies from untreated wastewater. Agricultural wastewater treatment for farms, and erosion control at construction sites can also help prevent water pollution. Nature-based solutions are another approach to prevent water pollution.[6] Effective control of urban runoff includes reducing speed and quantity of flow. In the United States, best management practices for water pollution include approaches to reduce the quantity of water and improve water quality.[7]

This is a video on how to save water.
Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment. Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth. It’s the reason we have Kool-Aid and brilliant blue waterfalls. It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.

In order to thrive, healthy ecosystems rely on a complex web of animals, plants, bacteria, and fungi—all of which interact, directly or indirectly, with each other. Harm to any of these organisms can create a chain effect, imperiling entire aquatic environments.

When water pollution causes an algal bloom in a lake or marine environment, the proliferation of newly introduced nutrients stimulates plant and algae growth, which in turn reduces oxygen levels in the water. This dearth of oxygen, known as eutrophication, suffocates plants and animals and can create “dead zones,” where waters are essentially devoid of life. In certain cases, these harmful algal blooms can also produce neurotoxins that affect wildlife, from whales to sea turtles.

Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways as well. These contaminants are toxic to aquatic life—most often reducing an organism’s life span and ability to reproduce—and make their way up the food chain as predator eats prey. That’s how tuna and other big fish accumulate high quantities of toxins, such as mercury.

Marine ecosystems are also threatened by marine debris, which can strangle, suffocate, and starve animals. Much of this solid debris, such as plastic bags and soda cans, gets swept into sewers and storm drains and eventually out to sea, turning our oceans into trash soup and sometimes consolidating to form floating garbage patches. Discarded fishing gear and other types of debris are responsible for harming more than 200 different species of marine life.

Meanwhile, ocean acidification is making it tougher for shellfish and coral to survive. Though they absorb about a quarter of the carbon pollution created each year by burning fossil fuels, oceans are becoming more acidic. This process makes it harder for shellfish and other species to build shells and may impact the nervous systems of sharks, clownfish, and other marine life.

To put it bluntly: Water pollution kills. In fact, it caused 1.8 million deaths in 2015, according to a study published in The Lancet. Contaminated water can also make you ill. Every year, unsafe water sickens about 1 billion people. And low-income communities are disproportionately at risk because their homes are often closest to the most polluting industries.

Waterborne pathogens, in the form of disease-causing bacteria and viruses from human and animal waste, are a major cause of illness from contaminated drinking water. Diseases spread by unsafe water include cholera, giardia, and typhoid. Even in wealthy nations, accidental or illegal releases from sewage treatment facilities, as well as runoff from farms and urban areas, contribute harmful pathogens to waterways. Thousands of people across the United States are sickened every year by Legionnaires’ disease (a severe form of pneumonia contracted from water sources like cooling towers and piped water), with cases cropping up from California’s Disneyland to Manhattan’s Upper East Side.

Meanwhile, the plight of residents in Flint, Michigan—where cost-cutting measures and aging water infrastructure created the recent lead contamination crisis—offers a stark look at how dangerous chemical and other industrial pollutants in our water can be. The problem goes far beyond Flint and involves much more than lead, as a wide range of chemical pollutants—from heavy metals such as arsenic and mercury to pesticides and nitrate fertilizers—are getting into our water supplies. Once they’re ingested, these toxins can cause a host of health issues, from cancer to hormone disruption to altered brain function. Children and pregnant women are particularly at risk.

Even swimming can pose a risk. Every year, 3.5 million Americans contract health issues such as skin rashes, pinkeye, respiratory infections, and hepatitis from sewage-laden coastal waters, according to EPA estimates.
Radioactive waste is any pollution that emits radiation beyond what is naturally released by the environment. It’s generated by uranium mining, nuclear power plants, and the production and testing of military weapons, as well as by universities and hospitals that use radioactive materials for research and medicine. Radioactive waste can persist in the environment for thousands of years, making disposal a major challenge. Consider the decommissioned Hanford nuclear weapons production site in Washington, where the cleanup of 56 million gallons of radioactive waste is expected to cost more than $100 billion and last through 2060. Accidentally released or improperly disposed of contaminants threaten groundwater, surface water, and marine resources. There are four main types of air pollution sources: mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces.Jan 17, 2018.

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.According to the National Oceanographic and Atmospheric Administration, 80 percent of marine pollution comes from land-based sources. The issue, however, is not limited to coastal environments; lakes, rivers, and water tables are affected on a large scale by pollution that comes from agriculture, industry, vehicle emissions, and products used at home every day. Runoff from soils and even pollutants in the air can settle in waterways, creating unsafe conditions for people and wildlife. Pollutants have many ways of making it into the water supply. Water pollution happens when toxic substances enter water bodies such as lakes, rivers, oceans and so on, getting dissolved in them, lying suspended in the water or depositing on the bed. This degrades the quality of water.

Not only does this spell disaster for aquatic ecosystems, the pollutants also seep through and reach the groundwater, which might end up in our households as contaminated water we use in our daily activities, including drinking.

Sources and effects of water pollution

Water pollution can be caused in a number of ways, one of the most polluting being city sewage and industrial waste discharge. Indirect sources of water pollution include contaminants that enter the water supply from soils or groundwater systems and from the atmosphere via rain.

Soils and groundwaters contain the residue of human agricultural practices and also improperly disposed of industrial wastes.

Types of water pollutants

Pollutants can be of varying kinds: organic, inorganic, radioactive and so on. In fact, the list of possible water contaminants is just too vast to be listed here.

I really think some causes of the water pollution is basically people throwing their wastes or trash in the water, Industrial waste, Sewage and wastewater, Mining activities, Marine dumping, Accidental oil leakage, The burning of fossil fuels, Chemical fertilizers and pesticides and Leakage from sewer lines. Some Animals will die and our planet will be filled with trash and garbage. And the garbage or trash may have toxic chemicals and the animals will die because of the toxic chemicals! We must save these animals ! Humans will have no space and plants may die because of all the garbage and there may not be enough air.
