Long and Short Essay on Water in English
Water is often considered to be one of the most important resources our planet has, water essay, and rightly so. The Earth is unique among almost all the other planets known water essay us for two reasons: first, it harbors life, second, water essay, it has water on its surface, and the former is the consequence of the latter. There are almost no doubts concerning the fact that life has first appeared in the water and existed in water for billions of years before finally entering the land.
Although this conclusion may be considered a bit far-fetched, the majority of scientists agree that life is only possible on the planets with liquid water; as a result, any astronomical body that has even a possibility of having liquid water on its surface is studied with utmost attention, for it is considered a potential home for extraterrestrial life. To put it in other words, a human can do without almost anything but water. If any other resource on the water essay Earth is exhausted, the negative results of it may be averted.
If we somehow water essay to use up or pollute our store of drinkable water, water essay, there is no way to set it right.

The levels are disorganized while the fish are directly affected by fat, oil and grease. BOD from cleaning, washing, dyeing, pulp centre, motor service station etc. BOD, COD from paper and pulp industry. Ammonia, acid, bacteria; nitrogen and urea from the fertilizer industry;. Food grain mills release pollutants like BOD, oil and grease, which together with water sources pollute the water. The water of these rivers has been polluted by the waste of industries located along the banks of the Ganges and Yamuna rivers. The colour of the water of the river Ganga has changed to the Kishanpur village, 10 km from Kanpur, after the waste of leather factories in Kanpur falls in the Ganges River. The effluent wastewater from the IFFCO chemical fertilizer factory at Phulpur near Allahabad is found in the Ganges River, from which fishes have been found dead for a distance of 16 km.
In present times, the use of various new methods in agriculture is increasing to get more production from crops. Due to new methods in agriculture, there has been an increase in irrigation, on the other hand, the use of chemical fertilizers, indigestible pesticides have also increased at a rapid pace. While these new experiments in agriculture have led to a huge increase in production, but damage to the environment especially water pollution. Defective farming practices have led to a huge increase in soil erosion, blocking the passage of rivers and raising the river bed.
Another cause of water pollution under agricultural effluents is the increasing use of chemical fertilizers. Most fertilizers are inorganic phosphate and nitrogen. Nutrition refers to the condition resulting from excessive enrichment of water by nutrients such as nitrate and phosphate. Water gets polluted due to an increase in the state of nutrition. The excess fertilizer added to the fields slowly flows with water and reaches the rivers, ponds and ponds. Water with high nitrogen content especially by reaching the lake, the process of eutrophication in the lake is intensified.
As a result, algae grow rapidly in water and decomposition bacteria are produced in large numbers due to the death of algae. In the process of decomposition of organic matter, the amount of oxygen in the water is greatly reduced, as a result, aquatic organisms are deficient and water gets polluted. The best example of malnutrition is Dal Lake. This world-famous lake has gone through the initial stages of malnutrition and get polluted. The southeastern part of this lake is getting contaminated at a rapid pace due to the discharge of water waste and agricultural drainage. River and pond water is used in various productive plants to prevent excessive heat effect of various reactors. This water, which has been heated as a result of the cooling process, is then dumped into the water sources.
Apart from industries, thermal pollution is also caused by steam or nuclear-powered power generating plants. Adequate natural water is used in energy plants for cooling the liquidators. Thermal pollution has a special effect on water organisms. Large organisms cannot tolerate high temperatures. With the increase in water temperature, the solubility of oxygen also decreases and the amount of salts increases. Due to the mixing of oil and oily substances in the river and other water sources from industrial plants, oily pollution occurs. There is a high possibility of oil pollution in the seas, due to which oil from the oil carrier keeps seeping in the sea and due to the crashing of the ships, there is a terrible fire. According to an estimate, about 50 lakh to 10 million tons of petroleum products are found in the sea every year for various reasons.
At present, numerous radioactive particles are spread far and wide in the atmosphere due to nuclear explosions and then gradually fall on the ground as sensitized which get into the water sources due to various reasons and through the food chain in the human body. Radioactive substances combined in water sources make water toxic. Since radioactive particles dissolve very slowly, their effect on water lasts for many days. Even some of the most developed nations like the United States are not protected from the effects of water pollution. Poor sanitary conditions, absence of adequate medical facilities and low awareness of health issues are some of the main causes of water pollution and diseases caused by it.
The solution to water pollution lies in a multi-dimensional approach that is directed towards eliminating various causes of water pollution. Water pollution refers to the contamination of natural water resources by harmful and toxic compounds, mainly due to various human activities. The introduction of a toxic substance into water bodies is harmful for consumption by humans, animals, and aquatic life. This results in loss of species, loss of biodiversity, habitat loss among various other complications. In further essays, we will discuss the causes and effects of water pollution. Organic and inorganic chemicals, pathogens, physical impurities and sensory factors such as temperature rise, which are widely found in water, are included in water pollutants.
Water pollutants can be divided into the following three classes based on their properties and parameters-. Physical pollutants include substances and ingredients that affect the colour, smell, taste, light vulnerability of water, conductors, total solids and its normal temperature etc. These mainly include sludge, suspended solids and liquid or other dissolved particles of silt and hot water coming out of thermal power plants and industrial units in certain conditions. Apart from these, paper, plastic debris and containers etc. can also be included. Physical impurities negatively impact the aquatic environment, causing staining by water discolouration. Chemical pollutants mainly include organic and inorganic chemicals, heavy metals and radioactive materials.
These pollutants affect the acidity, alkalinity and hardness of the water, radioactivity, availability of merged oxygen and chemical oxygen, etc. Pollutants found in surface water include detergents, chemicals used in household disinfection, aerated fats and oils, food processing wastes, residues of insect and pesticides, petroleum hydrocarbons, volatile chemical compounds, industrial solvents and cosmetic products, etc. are major organic pollutants. In addition to radioactive materials released from nuclear plants, inorganic chemicals, especially acids and alkaline waters from industrial units, nutrients extracted from fertilizers used in agriculture, especially nitrates, phosphates and fluorides through products of motor vehicles and industrial waste.
Organic pollutants contain unwanted organic materials that affect water-soluble oxygen, biological oxygen demand, immunity, etc. Among these, biological materials, pathogenic bacteria, coliform bacteria, algae, hyacinth, aquatic ferns and parasitic insects, as well as water plants, etc. are prominent. The total faecal coliform germs content in some waters of Indian water bodies is MPN per mg has been found more than the presence of pathogens at high levels in water indicates its insufficient treatment. With the ageing of untreated sewage originating from cities and infrastructural in old cities, the pathogenic discharge has also been found in surface drinking water due to sewage collection, leakage in the pipe-pump-valve system, etc.
Occasionally algae, hyacinth, aquatic ferns, etc. found in surface water and pathogenic microorganisms. Various types of harmful chemical substances and heavy metals present in the waste discharged from factories. Water is vital in our life due to the following reasons. It is essential for our survival. Experts estimate that on average a human body requires about 48 ounces of water to survive. The body utilizes water in to facilitate several functions such as: elimination of toxins from all body parts to the kidneys and quenching of thirst thereby eliminating dehydration that can weaken the performance of the body and its functioning. It also facilitates digestion of food and absorption of nutrients through their dissolving in water, transports nutrients, chemicals and heat throughout the body.
Water is our primary source of food. It does so by facilitating the growth of plants thus, the formation of food. Plants make their food by the process of photosynthesis. Here, starch is formed using water derived from the soil by air combining with sunlight. After this, the plant germinates in the presence of water and begins to grow and water supplies nutrients and materials to these plants. Water also facilitates the swelling, production of energy and loss of heat of a plant throughout its cycle, until it matures and is harvested as food. Additionally, water provides food through its numerous sources by being a home to fishes and aquatic life that are considered food. Water facilitates the continuance of life through reproduction.
Water facilitates this movement, and once fertilization occurs, the woman becomes pregnant. The developing offspring requires many nutrients to enable it to develop well, and it receives them through water referred to as amniotic fluid. During delivery, the first substance to come out is water to facilitate delivery, and once birthed, they are nourished using milk that is rich in water. Water also enables transportation. The hydrogen bonds present in water hold the water molecules together. This substance bonds with any molecule it can form hydrogen bonds with. The hydrogen bonds of water turn into ice when cooled down. The hydrogen bonds are stable and maintain their crystal like shape. The solid form of water which is ice is comparatively less dense as its hydrogen bonds are spaced out.
Water has high level of polarity. It is known to be a polar molecule. It is attracted to other polar molecules and ions. It can make hydrogen bonds and is thus a powerful solvent. Water can moderate temperature owing to its high specific heat. It takes a long time when it comes to heating up. It holds its temperature for long when heat is not applied. This is another property of water that renders it the ability to moderate temperature. As the water evaporates off a surface it leaves a cooling effect on the same. Water is required for most of the activities we indulge in our day-to-day life.
It is necessary for us to conserve it else our planet will be devoid of fresh water in the years to come. Here are a few ways in which water can be conserved:. We must not waste water and contribute our bit towards its conservation. We must practice and promote activities and plans that help in conserving water and protecting its sources to meet the current and future demands of living beings. Water is the most common liquid found on our planet. It is vital for the survival of every living being. However, while most part of our planet is covered with water, fresh water that can actually be used for drinking, cooking and other activities is quite less.
It is thus important to use this substance wisely. Water is present in three different forms on Earth — Solid, Liquid and Gas. Here is a brief look at these forms:. Solid : Water freezes at 0 degree to form ice which is its solid state. As water freezes, its molecules move apart and this makes ice less dense compared to water in its liquid state. This means that ice is lighter than the same volume of water in its liquid state. It can thus float on water. Liquid : This is the most common form of water. Water in its liquid state is used in several ways including drinking, washing, cleaning, cooking, irrigating fields and processing and preparing various products in industries. Gas : As water boils, it changes from liquid to gas, often referred to as water vapour. Vapours are always present around us.
When the water vapours cool, they form a cloud. It is the process wherein water circulates between land, oceans and atmosphere. This involves precipitation, snowfall, drainage in rivers, lakes and streams and its return to atmosphere by way of evaporation and transpiration. Water cycle is also referred to as hydrological cycle. Like most of the other developing countries, many parts of India also face scarcity of water. People in the country do not get clean water for drinking and there is water deficit for the purpose of sanitization as well. It is supplied for just a few hours each day mostly for a couple of hours in the morning and an hour or two in the evening. The quality of water has deteriorated in most of the water bodies in the country.
This is because of the discharge of industrial and domestic waste in water. The situation is expected to worsen in the times to come as the population of the country is likely to increase to 1.
