This article will cover three essays in particular. An Essay on Air Pollution, An Essay on Noise Pollution and An Essay on Water Pollution. Pollution is a broad term that describes a huge range of environmental problems. Pollution IS any unwanted change in the natural environment, caused by human activity. Pollution can come from a number of natural or man-made sources, including mining, agriculture and manufacturing.
There are many forms of pollution, but they all have one thing in common: they’re caused by humans. Pollution can be described as the release or emission of any contaminants into the environment that cause adverse effects to biodiversity and ecosystems, human health and welfare, property, or economic values.
We must deal with the negative effects or consequences of pollution in our everyday lives. Some people might even benefit from a little bit of pollution, but when it becomes excessive, it can cause all kinds of problems for humans and the environment.

Essay on Air Pollution [1000+ Words]
Our existence depends on air. We cannot survive for even a moment without air. Sadly, modern humans are actively contaminating the air they need to breathe to survive.
Particularly to blame for the air’s toxicity are factories. As it enters the atmosphere, the poisonous smoke emitted by the factories loses its toxicity. The result is that the environment around us also becomes polluted. In addition to this, smoke from automobiles, trains, trucks, and other moving objects pollutes the environment. They were created, nonetheless, to reduce the need for human work and time.
Nothing in the world is more priceless than life. What use does the blind race of progress serve if all these facilities cast doubt on our existence? To hold the industrial sector solely accountable for this would not be appropriate from any standpoint. Human society is divided into numerous groups. They share accountability for it.
Causes of Air Pollution
When coal and other mineral fuels are used in furnaces, factories, power plants, automobiles and trains, high amounts of carbon dioxide and sulfur dioxide reach the air. Incomplete burnt mineral fuel from motor vehicles also reaches the atmosphere.
In fact, fine particles of carbon-dioxide, sulfur-dioxide, carbon-monoxide, dust and other compounds are found in the air in the form of pollution. From this point of view, motor vehicles have been considered as the ‘biggest polluters’.
There are industrial areas and a many factories in the metros. Sulphur acid, hydrogen sulfide, lead, mercury and other chemicals are used in these factories. These include chemical factories, refineries, fertilizers, cement, sugar, glass, paper, etc. The pollutants from these factories are carbon monoxide, nitrogen oxides, various types of hydro-carbon, metal-particles, various fluorides, sometimes particles of radio-active substances, non-flammable fractions of coal and liquid fuels reaching the atmosphere as pollutants.
A large amount of dust and smoke is released from various metallurgical processes. They contain air pollutants such as lead, chromium, beryllium, nickel, vanadium, etc. Through these research processes, particles of zinc, copper, lead, etc. also continue to reach the atmosphere.
Our farmers spray a variety of pesticides to protect the crops that are burning in the fields from pests and diseases. These drugs are – organic, phosphate, lead, etc. These chemicals work to poison the air.
Many countries have carried out nuclear explosions to obtain nuclear energy. Nuclear furnaces have been built in these countries. This causes some air-pollutants to get into the air. These include uranium, beryllium chloride, iodine, organ, strasium, cesium carbon, etc.
Cutting of trees and forests – Trees, plants, trees and vines are natural means of purifying the environment. Air pollution is increasing rapidly due to indiscriminate and irregular felling of trees for house-building, timber, furniture, paper industry and firewood etc. It also affects the monsoon. It doesn’t rain on time. There is a situation of excessive rainfall and drought.
Impact of Air Pollution on public life
The impact of air pollution on human life is as follows : Sulphur dioxide and carbon-dioxide gases dissolve in rainwater to form ‘acid rain’. Acid rain means acid rain or acid rain. Organic acids and sulfuric acids have a high impact in this ‘acid rain’.
Thus, when these gases enter the lungs through respiration, they absorb moisture to form acid. These cause lesions in the lungs and respiratory ducts. Not only this, germ-containing dust particles get trapped in them and give rise to lung diseases. When these gases reach the leaves of plants, they destroy the ‘chlorophyll’ of the leaves. The green color of the leaves in plants is due to the presence of ‘chlorophyll’. This chlorophyll itself prepares food for plants.
Due to the presence of ‘ozone’, the leaves of trees and plants start respiration more quickly. Due to this, food is not supplied in proportion. The leaves begin to be destroyed due to lack of food. This is the reason why they do not lead to photosynthesis. This has an effect on the amount of oxygen in the atmosphere.
Motor vehicles, industrial plants, household stoves and smoking add carbon monoxide and carbon dioxide to the air. For this reason, in the respiratory process, along with ‘hemoglobin’ in the blood, oxygen stops there. As a result, the heart has a serious effect on the blood circulation system. Hemoglobin is the base of the blood. If these toxic gases continue to go into the lungs with breathing for a long time, then death is also possible.
Oxides of nitrogen and some organic gases obtained from the burning of residual materials, chimneys of chemical industries and petroleum and some organic gases are converted into ‘ozone’ and other pollutants in the presence of light. Its side effects cause water to come out of the eyes, it is also difficult to breathe.
An excess of carbon dioxide in the atmosphere hinders respiration. There is a possibility of the earth’s surface becoming hotter than normal. The presence of nitrous oxide leads to an increase in lung, heart and eye diseases. Fine particles of lead and cadmium combine in the air to act as poisons. Iron ore and silica particles give rise to lung diseases.
Radioactive radiations accumulate tropium in place of calcium in bones. Similarly, many dangerous elements are gathered in place of potassium in the muscles.
Prevention of Air Pollution
Air pollution can be prevented more easily in places from where pollution is generated in the air. Nowadays, there are some pollution-controlling devices available that can prevent pollution. Electrostatic precipitators, filters, etc. are devices that can be installed in industrial plants to prevent air from being polluted. At present, the following measures are possible to control air pollution:
By removing sulphur from pollutant fuels, such as sulphur dioxide or by using modern fuels by not burning conventional fuels. Modern fuels include natural gas, electric furnaces, etc.
Pollutants from motor vehicles can be used by installing a ‘catalytic converter’ device.
By applying high chimneys, pollutants can be prevented from accumulating on the earth’s surface.
Air pollution can be controlled by setting up industrial plants away from the population and installing pollution-preventive plants.
Air Pollution Essay Conclusion
Air pollution can be prevented to a great extent by planting more trees in vacant and waste land and creating green belts in industrial areas. According to scientists, if 23 percent of the population is forested, then air pollution does not harm.

Short Essay on Noise Pollution [700+ Words]
Today, the problem of noise pollution is creating a stir all over the world. This has a major adverse impact on the regional environment. Noise has a tremendous role in increasing mental diseases and diseases of ears, eyes, throat etc.
The ‘pungent sound’ is called noise. ‘Decibels’ have been arranged to measure the noise intensity. Whether it is the thunder of the plane or the whistle of the train, whether it is the horn of the car or the scream of the loud-speaker – the noise anywhere does not leave us. This pollution is spreading day by day.
Noise also affects the heart and mind. This causes our arteries to shrink. The heart starts working at a slow pace. It also starts having an adverse effect on the kidneys.
Constant noise increases ‘cholesterol’. This causes a permanent stretch in the blood vessels. This leads to the possibility of a heart attack. The nervous system is affected by more noise. It also has a bad effect on the brain. This is the reason why most of the people living around the airport become insensitive.
Noise has such a bad effect on children that they not only hear high, but their nervous system is also affected. As a result, children do not have proper mental development.
Unbearable noise also has a bad effect on childbirth. Pregnant women living in the vicinity of the airport give birth to low-weight babies. If a pregnant woman is in the midst of constant noise during pregnancy, then health of the baby in her is also badly affected.
There should be noise up to a maximum of 45 decibels in any city. Mumbai, Delhi, Kolkata and Chennai recorded noise levels of more than 90 decibels. Mumbai is considered to be the ‘third most noisy city in the world’. Delhi is also at par with Mumbai in terms of noise pollution. If this continues, by 2010, 50 percent of Delhi-citizens will be severely affected.
According to international criteria, noise can be tolerated up to 56 decibels. However, around hospitals it should be only 35 to 40 degrees.
In western countries, noiseless vehicles have been made to prevent noise pollution. Fences have been erected along the roads to prevent noise there. An underground path has been built. Noise-polluting vehicles have been banned. Apart from these, most countries have stopped flights at night.
The movement against noise pollution in India is very slow. According to environmental experts, the major reason for this is that most of us consider it not ‘pollution’, but ‘a part of daily life’.
According to a survey, if a person is constantly in a very noisy place, then he becomes a victim of deafness permanently or forever. The highest number of such cases was found in 40 per cent. The foundry industry and the lowest in oil mills at 32.7 per cent. Textile mills were found to have 32.6 per cent, refineries 28.2 per cent, fertilizer factories 19.8 per cent, power companies the lowest i.e. 8.1 per cent.
If the sound of the flute is very loud then the person becomes a victim of mental illness. In many cases, he starts behaving aggressively. Most of the noise is from loud-speakers. Apart from this, road and rail and air traffic, noise of industrial units, screaming sirens, firecrackers etc. are included.
No comprehensive law has yet been enacted in India to control noise. If no effective measures are taken to avoid this pollution, most of the people will become deaf due to it in the next twenty years.
Noise pollution control ranks at the bottom of the priority list of the Union Environment Department and central and state pollution control boards.
Control on Noise Pollution can be achieved through the following measures:
- Separate routes should be made for slow and high speed vehicles and pressure horns should be banned in them.
- Slums and colonies should be constructed in such a way that they remain at a considerable distance from the road.
- A large part of the land between the main road and the settlements should be left vacant.
- Public awareness programs should be made to make people aware of noise pollution.
- There should be a complete ban on the use of loud speakers during marriage ceremonies and parties etc. and the use of high-powered firecrackers should be banned on festivals or happy occasions.
- The honking of vehicles should be stopped unnecessarily.
- Such laws should be made so that noise can be reduced on roads, factories and public places.
Short Essay on Water Pollution [600+ Words]
Water is very essential to our lives. Not only for humans, but also for animals and birds. Water is the basis of life. No organism can survive without water. After eating or after doing any work, the heat in the human body increases. That heat comes only from water. Water has the highest utility in every human work. In areas where air and water are contaminated, the life of biologists is in crisis.
In the twentieth century, man-civilization and science-technology developed very rapidly. Of course, human life has improved and improved, while there has also been a lot of loss. Today, the air-water-sky three has been indiscriminately and uncontrollably exploited.
For this reason, the question of protecting human existence stands before us. Ganga is considered the most sacred river in India. It is a river that travels to heaven. The Ganges is considered a river for many sins. The same life-giving Ganga has been polluted today-by the toxic garbage of factories.
The government of India has also carried out a comprehensive program for cleaning the Ganga, self. The central Ganga authority was also formed under the chairmanship of Prime Minister Shri Rajiv Gandhi, but its serenity has not returned yet. This is also the case with other rivers.
There is a lot of pollution in the reservoirs as a result of our unscientific living. Pollution has increased so much that bathing in them and using their water leads to dangerous diseases such as skin disease and paralysis.
The trend of bawls is almost over. In every village of the country, water has been used since time immemorial, but in many areas, deadly polluted elements are found in Wells.
Reasons of Contamination of Water:
Water becomes contaminated mainly for the following reasons:
- Keep the water stable,
- Water from the city’s dirty drains and drains,
- Different types of mineral salts in water,
- Getting germs of infectious diseases in water,
- Bathing and washing clothes with soap, shampoo, etc. in the water of pools,
- Release of chemicals from factories and factories etc. in water sources,
- Bathing, washing, cleaning of shoes near River, wells and other water sources.
- Bathing in ponds and draining feces and urine in them,
- By dropping waste and chemical residual materials from factories into water sources. Almost 1700 industries that require waste water-treatment in India.
The amount of water in the human body is about 70 percent. This is the water that we get from nature.
Categories of Natural Water:
The Nature Water can be divided into following Four Categories:
- Under the first category comes ‘Rainwater’.
- In the second category comes the ‘water of the river’.
- Under the third category comes the water of ‘wells’ or ‘soops’
- The fourth category includes ‘water of the sea’.
Prevention of Water Pollution:
Water pollution can be prevented by following measures:
- Periodically in the wells should be sprayed red drug.
- Wells should be covered by nets, etc., due to this, garbage and dirt cannot get into the well.
- When you know that the water is polluted, boil it first, then consume it.
- Use alum to keep dirty water clean. Use alum only according to the amount of water. This will cause the amount of dirt in the water; everyone will sit down in the bottom of the pitcher.
- Water tanks and cisterns should be cleaned periodically.
- Installation of ‘treatment plants’ in industrial units should be made mandatory. It should be taken to punish the industries that do not follow it with due diligence.
- Do not throw waste and sewage into the river and use new technologies to generate energy from them and make compost from it.
- Don’t give licenses to highly polluting factories.
- Ban on killing frogs, turtles, etc. in rivers, ponds, pools and Wells.
- Be strict against any type of water contaminants.
