Why do we need to conserve water. Start in science

The source of life on planet Earth is water, and the quality of life of the creatures inhabiting the planet depends on its purity in reservoirs. In all living cells, down to the smallest, a certain percentage is occupied by water. In humans, this figure is approximately 70%. So that humanity does not die out, and the Earth does not turn into a desert, that is why it is necessary to conserve water and monitor the purity of water bodies.

Man and water

All people on the planet know the expression "water is life (or the cradle of life)", but few people think about its meaning. Indeed, everyone knows that a person will not “last” more than five days without water, and sometimes even less. Why, then, do people treat the planet's water resources so irresponsibly? There are several answers to this question, but the main ones are related to human life:

"After us, even a flood" (quote from the Marquise de Pompadour). So say people who, for the sake of personal gain today, do not think about the consequences of their actions for the next generations of people on the planet. For several decades, factories and plants in many countries polluted water bodies with sewage until environmental disasters began. Only then did the world understand why it is necessary to conserve water. The same applies to agricultural activities of people, when, in pursuit of crops, they introduced chemicals into the soil that poisoned groundwater or fell into water bodies with storm streams.
After the seas began to ply not sailing ships, but diesel ships, tankers and nuclear powered ships, pollution of the oceans became a worldwide problem. Their crashes and the release of tons of oil products into the water also caused environmental disasters.
The release of thousands of tons of harmful chemicals into the atmosphere has led to the formation of such a phenomenon that they poison both the soil and water bodies.

Why it is necessary to protect and conserve water on the planet, today they begin to explain to children in natural history lessons from grade 3. Perhaps this will help raise a new generation of people who will consciously approach the use of natural resources, because they are not endless.

The uniqueness of water

All people know what water is:

As a chemical element, it is a compound of 20% hydrogen and 80% oxygen, but at the same time it is a liquid, although in all respects it should be a gas.
It is a transparent liquid, which is the only one of all the chemical elements on Earth, which can be in all three forms: gas (in the form of vapor), liquid and solid form (as ice).
Water is present in all metabolic processes of living cells.
It dissolves many substances.
Without it, all life on the planet will die.

This is not the entire list of properties, but it is already becoming clear why you need to conserve water and reservoirs.

Unique structure

The most surprising thing was the cluster structure of water, which was discovered quite recently. Recent studies by scientists have proven that this liquid is able not only to record information, but also to store it for a long time.

This discovery turned all the ideas of scientists about the structure and origin of life on Earth. If earlier the phrase "water is the cradle of life" meant that everything that exists was born in it, which is confirmed even by the Bible (the second day of creation), today it has acquired a different meaning. Any information can be recorded on a water cluster that will rebuild its original structure, which makes it possible to change the state of living matter.

That is why it is necessary to conserve water, because when it enters the human body, it brings the information that is recorded in it into its liquid medium. For example, it can be data on unfavorable conditions in which the water source is located. In this case, a person who does not even live near this reservoir, but receives water through long pipelines to his apartment, is able to get sick with the same ailments as the inhabitants of this area.

Main characteristics of water

Schoolchildren receive their first scientific knowledge about this chemical element in the classroom in nature studies in grade 3. “Why Conserve Water” is the topic of the lesson on the basic properties of water. Children get acquainted with this liquid from the point of view of science and learn what role it plays in the development and existence of living matter.

Water is characterized by:

Dissolve various substances, so there is no truly pure water in nature. Not so long ago, Russian scientists allocated several grams of such a liquid, but its production took a lot of water and required special equipment. In this environment, not only salts dissolve, but it also contains gold and other precious metals.
Depending on the amount of salt, it is divided into layers in the oceans. Since the saltier the water, the heavier it is, which means it is closer to the bottom. Due to this property, each layer of water in the World Ocean has its own percentage of salt, in which certain microorganisms, fish and marine animals "live". It was this feature that allowed evolution on Earth to develop in the direction that we observe today. That is why it is necessary to protect water bodies and conserve water, because if this balance is disturbed, the planet will experience a gradual global extinction of all living things.

Do not dissolve some chemical elements and substances. It was this property that contributed to the origin of life. Fats, insoluble in water, are the basis of cell membranes, which became the first prototype of everything. Indeed, according to scientists, it was in the ocean that unicellular organisms originated, from which, after millions of years, the animal and plant worlds originated.
It turns into ice when frozen, which is not great as many chemicals can take this form. Surprisingly, water is the only liquid that is lighter in weight in solid state than as a solution. Thanks to this feature, people and all other creatures are still alive, because if ice were heavier than water, it would sink to the bottom of reservoirs, destroying everything in them. Homo erectus would hardly have survived the ice ages if it had other properties, because at that time its existence was largely dependent on water and the fish and animals living in it. Little has changed since then, and people still depend on water bodies, which is why you need to conserve and protect water.
When heated, turn into steam, which is characteristic of many liquids, but water is modified not only in this way. It also evaporates from the surface of water bodies, and even ice, which makes this process continuous. Thanks to this feature, the water cycle occurs in nature, which students learn about in natural history lessons. But little attention is paid to the fact that it is this property of water that creates a favorable climate on the planet. This is why you need to conserve water. This will be discussed briefly below.

Everything in nature is based on the properties of water, and if this balance is disturbed, environmental disasters are inevitable. This should be understood by children from school, in grade 3. The project “Why water should be saved”, done by them independently or together with their parents, helps them to realize their part of responsibility for the quality and quantity of water bodies on the planet.

Reasons for water pollution: heavy metals

Everyone knows that without water, all life on Earth will perish, but few people think that there are only 3% of it in the fresh state. And, despite such a scanty amount of it in the total volume of the planet's water surface, humanity continues (consciously or not) to destroy and reduce this indicator. That is why it is necessary to protect reservoirs, rivers, conserve water, because its shortage is acutely felt in many countries, especially on the African continent.

Industrial plants are the main cause of water pollution. Heavy metal contamination is what happens when wastewater is discharged not only into water bodies, but also into the soil. They seep through it and, upon reaching groundwater, become potentially dangerous to the human body. History knows a lot of facts when people got sick, mutated or died because of artesian or well water. When such water was taken for analysis, nickel, mercury, lead, cadmium and other metals were found in it, which constitute the basis

Radiation contamination

With the development of nuclear production, the contamination of water by its waste has increased. This type of energy harms not only water, but also all life on the planet. This happens in the form:

Radiation precipitation. The vapors generated at the sites of nuclear tests subsequently rain down even in regions located hundreds and thousands of kilometers from the source.
Wastewater. Nuclear enterprises, getting rid of production waste, "bury" them in the ground. Even the best concrete sarcophagus is not able to contain radiation for a long enough time. Today everyone knows about the accident at the Chernobyl nuclear power plant, and the consequences and damage that it caused to people and nature.

Accidents on nuclear submarines and ships with nuclear fuel engines. The waters of the oceans suffer more from this, but fumes from their surface poisoned by radiation can also harm rivers and lakes located far from the source of infection.

Perhaps it is still difficult for grade 3 schoolchildren to understand how harmful radiation is for all life on the planet, but teachers, when asking them to write a story as their homework, why water should be conserved, should mention the existing problem.

Inorganic contamination

Every year people go deeper and deeper underground, extracting minerals from its bowels. Wastes from the production of mines, oil and gas rigs destroy fresh water bodies with inorganic compounds of alkalis, metals and salts.

An example is the dire ecological state of the Sea of \u200b\u200bAzov.

Sewer problems

The consequence of global urbanization has become sewage wastewater, which daily carries food waste, residues of detergents, human waste products and much more into fresh water bodies.

Once in the water, these substances contribute to the development of pathogenic microorganisms that can lead to illness and even death of thousands of people living in cities if they enter their taps through water pipes. History knows examples of epidemics of dysentery and typhoid fever.

Synthetic waste

Nitrates and phosphates, which are used for the production of fertilizers and detergents, get into the aquatic environment and provoke the formation of blue-green algae. It tends to not only grow very quickly, but also completely destroy all life in the reservoir.

In place of lakes, swamps appear in which there is no life.

Compliance with laws

The problem of pollution of fresh water bodies, like seawater, is very urgent today. In most countries, appropriate laws for the protection of nature and water resources are adopted at the state level. Subsequently, special bodies monitor compliance with the norms and the environment in the regions. All violators will face fines and litigation. In most European countries, the USA, Canada and other highly developed countries, environmental laws are enforced by the population, since the penalties for non-compliance are quite severe.

The composition of the water, where enterprises or farms dump their waste, is constantly checked, and if it does not meet the permissible norm, then the consequence may be the complete elimination and closure of the "culprit" with the payment of all fines and legal costs.

Water and human health

Scientists have long been talking about the relationship between the physical and mental health of people and the water they drink. It is believed that up to 90% of diseases are associated precisely with the quality of fresh water that a person consumes. This is not surprising, since the human body consists of 70% of water, which is also capable of recording and storing information, like its counterparts in the seas, rivers and lakes.

When a liquid containing harmful substances enters the body, the internal environment of a person is rebuilt, which causes various diseases up to cell mutation and DNA changes. That is why it is necessary to conserve water, because the quality and duration of human life depends on its composition.

The emergence of deserts

No plant on Earth can survive without water. The exception is seeds, which for many years in a dry environment can retain their properties, but even they require liquid for further growth.

According to archaeologists, once upon a time there were no deserts on the planet, and in place of those that exist today there were seas and lakes. Climate change and human activities have led to their occurrence. The most striking example is the Aral Sea.

School projects

The fact that students from grade 3 are explained what water is on a global scale and how much life on Earth depends on its quality, gives hope that a new generation of people will be able to solve the ecological problem.

The project "Why you need to conserve water" will broaden the horizons of children and help to look at the world that surrounds them in a different way.

In this material, you will find ten simple rules, the implementation of which will allow you to reduce water consumption in your household and make your contribution to the conservation of the planet's water resources.

Unfortunately, every day our civilization causes irreparable damage to the ecosystem of our planet. Every day, rains and drains carry tons of waste from human economic activities into the system of water resources of our planet - these are fertilizers from the fields, and products of fuel processing from highways, and the remnants of building materials, and food waste, and biological waste. All this ends up in the same reservoirs from which we take drinking water, where our children bathe and where we fish. The negligent use of certain substances can even pollute groundwater. Therefore, it is necessary to follow some rules, there are few of them, but they are extremely important.

Save water in your yard

1. Using water-permeable coatings will significantly reduce the loss of water from your site. Asphalt and concrete surfaces for paths and parking areas can be replaced with masonry or gravel masonry, special lawn gratings and wooden decking. A variety of plantings and lawns will also be a nice addition and help conserve water. Planting vegetation below the level of the location of solid surfaces will allow water flows to saturate the soil under these plants, this will make it possible to save on watering.

2. Landscaping of territories by local representatives of flora will help conserve water resources, since these plants are most adapted to the natural climatic conditions of the region and do not need special care. The use of natural fertilizers, such as compost, peat, bone meal, stimulates plant growth, conserves moisture in the soil and does not have a negative impact on the environment as a whole. Moreover, using food waste as “food” for the soil is an excellent solution for disposal of such waste.

3. Do not overmoisten the soil. Abundant wetting of steep slopes and narrow soil strips is ineffective. Therefore, reducing the amount of moisture intended for such landscapes will prevent water from flowing onto roads and sidewalks, saving it for more important purposes. For dense soils with a low peat content, drip irrigation and microspray systems would be appropriate types of humidification. Waterlogging of lawns also entails leaching of the fertile soil layer. Watering plantings before sunrise or after sunset will help minimize moisture loss due to evaporation.

Save water in your home

4. Conserve water! Everywhere they talk about it, but it will not hurt to remind you - TREAT WATER CAREFULLY. Sensory faucets are very convenient (but not very cheap). Use a different intensity of flushing water in the toilet, depending on your needs. Operating washing machines and dishwashers instead of manual labor also reduces water consumption.

5. Store and dispose of household and chemical products “correctly”. Every dwelling contains such “gifts” of the chemical industry as solvents, paints, synthetic oils, glue, and building materials. Many of them contain harmful ammonia, formaldehyde, phenol, petroleum distillates. It is best to keep them away from sinks, toilets and drainpipes, thus keeping the water free from contamination. But such hazardous substances may end up in nearby bodies of water. Improper disposal of medicines and personal care products carries the risk of water poisoning from pharmaceutical waste. And then we drink such water. In developed countries, the issue of waste disposal is regulated at the state level. The programs for returning unwanted products to the manufacturing plant turned out to be very effective. At the enterprise, the resulting waste is disposed of responsibly and without harm to the environment.

6. Use organic household products. By purchasing household cleaning products that are "friendly" for the environment and water in particular, you not only preserve nature for future generations, but also prevent the harmful effects of chemicals on your health.

your car

7. Disposal of used engine oil. Never pour used oil into gutters or simply pour it on the ground! One liter of engine oil can spoil about 950,000 liters of drinking water! The ideal way to "get rid" of this unnecessary substance and save water is to transfer the "waste" to specialized centers. And so that the working fluids of the car do not spontaneously leak out, it is worth taking care of its timely maintenance.

8. Cultivating the "green" principles of car wash. Oddly enough, professional car washes are less harmful to the environment than a manual car wash with a bucket, rag, and questionable detergent. Of course, only on condition that the drainage system of "professionals" is organized correctly. This means that the used water circulates in a closed cycle: after passing through the filters and being purified, it returns to the washing system. Otherwise, water flows directly into the sewer system or spreads over the surface of the earth. The second advantage of professional car washes, as opposed to home “bathing”, is the ability to save half of the water, because you will have to spend half of it! Innovative technologies suggest completely abandoning the "source of life" by using a waterless sink.

In your society

9. "Pollutants": find and neutralize. Of course, nothing happens in this life. Therefore, to preserve water and other natural gifts, it is not enough to adhere to the rules of "etiquette" in relation to the environment. It is necessary to promote and popularize the correct handling of water among your friends and acquaintances. By teaming up with like-minded people, within the framework of the current legislation, it is possible, for example, to monitor potentially hazardous production facilities for compliance with environmental safety rules.

10. Be socially active. Forewarned is forearmed. It will be extremely useful to learn about ways to protect water resources, current investment programs, rates of fees that are paid for the use of water. You can clean beaches and water areas of garbage, plant plants, take samples to determine the quality of water in local waters. In one word - to protect water.

By using even one of the above recommendations, you can bring significant benefits to yourself and society. There is hardly a single representative of the fauna or flora that pollutes the environment. Humanity, unlike animals and plants, is endowed with outstanding intellectual abilities. However, we sometimes behave "inappropriately" in relation to Mother Nature. But, as they say, "everything ingenious is simple"! Let's just brilliantly PROTECT WATER!

For those who are especially interested in this topic, we have prepared another material in which this topic was expanded more broadly and focused only on the household. You can familiarize yourself with it by clicking on the link - "Save water, or how to save water in the household."

In fact, only 1% of the total amount of water a person can use for their own purposes. Most of the water on Earth is salt seas and oceans. This water must not be drunk and is also not suitable for many technical purposes.

Water is our main wealth, it cannot be replaced by anything. After all, the human body consists of more than half of water. It is impossible for a person to live without water. Water is food, washing and bathing, washing dishes, cleaning the house and outside, watering plants, caring for animals. In addition, water generates energy, is expensive for ships and boats, and is used in production for cooling and washing.

If a person can live without food for more than a month, then without water only a few days. Animals cannot live without water for more than ten days, let alone fish and animals living in water. Plants wither and die without water.

Therefore it is very important save water, spend it sparingly, do not pollute. For example, we spend about 100 liters of water on washing a mountain of dishes under a strong stream of water. In an hour, about 1000 liters of water will pour out of an open tap. It takes 150 liters of water to fill a bathtub even halfway. Contaminated water bodies are very dangerous. Firstly, fish and birds die in them, and secondly, water, evaporating from such a reservoir, forms clouds and falls on the ground with acid rains. Such rains are dangerous for all living things.

Conserve water.

I. Choice of research topic.

Vii. Research results:

Water is the source of life.

Water is a part of any living organism. It is enough to crumple a leaf of a plant in your hands and we will find moisture. In the body of animals, water is usually more than half the mass. There is a lot of water in the human body. Our body is almost 2/3 water. A living organism constantly consumes water and needs to replenish it. Fields and forests drink water. Neither animals, nor birds, nor people can live without it.

With the development of mankind from the most ancient times to the present day, water has become increasingly important. At first, she carried the first fragile ships on her. Then they began to irrigate fields with it, created the first primitive water pipes. And now it is already rotating the turbines of modern hydroelectric power stations, carrying giant ships ...

Water is in danger!

In recent centuries, in addition to natural pollution of natural sources with soil particles, rocks, mineral salts, etc., the problem of municipal, industrial, agricultural water pollution has arisen.

Water bodies are polluted by wastewater from industrial and municipal enterprises, during the harvesting, processing and alloying of timber, water from mines, mines, oil fields, emissions from water, rail and road transport.

The widespread use of synthetic detergents in everyday life and industry leads to an increase in their concentration in wastewater. At a concentration of 1 mg / l, small planktonic organisms such as algae, daphnia, rotifers die. At a concentration of 5 mg / l, fish die. Synthetic detergents are practically not removed by treatment facilities, so they quite often end up in reservoirs, and from there into tap water.

Water protection.

For the purification of liquid effluents, special treatment plant systems are used. For the treatment of domestic wastewater, as well as for each enterprise, its own treatment facilities are designed.

Water protection is a system of measures aimed at preventing and eliminating the consequences of pollution and depletion of waters, their rational use. Thanks to special protection measures, the ecological well-being of water resources is ensured. Water legislation regulates not only water consumption, but also the conditions that must be observed in the territories adjacent to water bodies. Drinking water quality standards are contained in a special document - the State Standard “Drinking Water”.

Why water should be protected.

Water on Earth is both a lot and a little. It is abundant in the oceans and seas, but the sea salt water is not suitable for drinking, as well as for many technical agricultural industries. Fresh water is significantly less and a third of the world's population is experiencing an acute shortage of it. The limited supply of fresh water is further diminished by pollution.

Our research.

Having studied the relevant literature on this issue, having conducted a practical lesson “How to treat polluted water”, as well as having learned about water treatment facilities in our city (water supply and sewerage treatment facilities of the Astrakhan municipal unitary enterprise “Vodokanal”), we conducted an interview game among relatives. After analyzing the answers of our relatives, we compiled questionnaires with similar questions to find out the attitude of other students in our classes and their parents to this problem.

The survey involved 28 people: 16 children and 12 adults.

Questions

From the results of the table, we concluded that adults and most students are aware of the danger of water pollution for human life and the need to respect the main wealth of the Earth. Most families have their own water treatment systems. But not all survey participants are aware of the water treatment facilities in our city.

In addition to the questionnaire, we developed a class hour on the topic: “Why water should be saved”, which was held in grades 2 "a" and 3 "a", where we shared with the students the results of our research, talked about what measures are used to protect and purify water in our city, than we - children can help in solving this problem.

Disciple.

The human body, including blood, brain, is more than half water. And some plants contain even more of it. It is enough to pick and crush a leaf of the plant in your hands to make sure of this.

Pupil

Water is an important substance for the body: for 1 kg of a cow's body - 600 g of water, a duck - 700 g of water, a jellyfish per 100 g of a body - 99 g of water. Thus, we see that water is a part of any organism.

Teacher.

The planets orbiting the sun have their own colors. Venus is bright white. This is the color of the enveloping clouds. Mars is reddish. This is the color of the Martian sands. Neptune is bluish, the color of its gases. And our Earth in images from space looks blue. This is the color of its oceans and seas. Do you know any other bodies of water?

They say she is everywhere!
In a puddle, in the sea, in the ocean
And the water tap.
Like an icicle freezes
Creeps into the forest with fog,
It is called a glacier in the mountains,
Curls like a silvery river.
We do not notice her.
We are used to the fact that water is
Our companion is always.

And there is no water - no, no, no ...

Teacher.

You all know Pushkin's tale of how an old man caught a goldfish in ancient times. How is this happening today?

A scene is played out.

Leading.

Denis went to the river to fish. Once he threw his fishing rod into the river - he caught a bottle of juice. The second time he threw down the line - caught out a torn shoe. For the third time, I threw the line and came across a small fish. Denis felt sorry for the fish, he decided to let her go into the river - let him grow up! And suddenly the fish spoke in a human voice.

Small fish.

Don't let me go back into the river! Better to throw in an aquarium with clean water. Mochenka no longer lives in the river!

Teacher.

Why didn't the fish want to stay in the water? After all, water is her home!

Pupils.

The water in the river must have been dirty.

Teacher.

How does water pollution happen? What danger threatens fish and other inhabitants of water bodies? Why?

Disciple.

There is less and less clean water on Earth. Plants and factories, power plants consume a lot of water and at the same time pollute it with industrial waste.

Fish, plants, animals - all living things perish in such water. Dirty waters poison the air and cause disease. But is there a limit to water pollution? After all, this cannot go on forever.

To conserve water means to conserve life, health, and beauty of the surrounding world.

Research results.

Teacher.

In our city, too, not everything is safe with the cleanliness of the reservoirs. Industrial waste is dumped into the Volga River. Debris along the banks of the river gets into the water and clogs it. Car washing near a river contributes to pollution.

Summarizing.

Teacher.Now let's take stock of our class hour and formulate the rules of careful attitude to water.

Pupils.

Pay attention to whether the water from the tap at home or at school is leaking in vain. If you notice this, turn off the tap.

It happens that we waste a lot of water uselessly without noticing it. For example, you wash your hands, wash your face under a strong stream. Turn off the tap a little. This will not interfere with washing, and less water will leak.

Learn how to brush your teeth without wasting water. To do this, do not leave the tap open while brushing your teeth and rinsing your mouth. Pour water into a glass immediately and turn off the tap. It is very convenient to rinse your mouth out of a glass. And how much water will you save!

You want to chill lemonade and keep the bottle under a cold stream. Wouldn't it be better to put the lemonade in the refrigerator and save the water?

If water leaks due to a malfunction of a tap or a water pump, you must immediately inform an adult.

Do not litter on river banks, do not wash cars in them.

Teacher.

Knowing and following the water conservation rules will help you conserve water.

Conclusions:

In the course of the research, we expanded our knowledge about water, got acquainted with the causes of pollution of water bodies and measures for their protection, learned how to treat water carefully and save it.

Water is life. The most ancient civilizations arose near the water, in the valleys of great rivers: the water “left” - cities and villages were emptied.

We will not keep the water tap open unnecessarily, we will not pollute the reservoirs with garbage, we will take care and save every drop of water!

“Water must be protected,” parents and teachers say, at home and at school. They write about it in books and print in newspapers. And this lesson looks very strange. Why take care of it, if there is so much of it around?

At home he turned off the taps - it flows, with good pressure, with a wide stream. If you want it cold, you want it hot. Cook food, bathe, wash as much as you like. He got smeared on the street playing football - a column nearby. I pressed the lever - the water flows like a river, wash, splash as much as you like. And there are many lakes, rivers, ponds in the city and outside the city. And the sea! If you go to the sea in the summer, you generally cease to understand why it should be so protected, this water, if its huge volumes, wherever you look.

Now let's calculate more specifically. Each person drinks about one and a half to two liters of water daily. Yes, plus soup, and even tea, coffee, all kinds of compotes. It's just inside. Hundreds of liters a day are spent on washing, bathing, and other needs of each of the residents of an apartment building. And in the village there are still cows and sheep to drink, and water the garden every evening in hot weather. The water also moves the blades of electric turbines, generating energy for us, and also carries huge ships on its waves. And how much water is used in any production! For cooling, moisturizing, rinsing. Tons, tens of tons, hundreds of thousands of tons daily.

Now let's look at our planet. No, not to the Universe - it is just infinite. And the planet, the Earth? It has northern and southern extreme points, western and eastern. That is, it is limited in size, whatever one may say. And, consequently, its natural resources are also limited. Imagine for a minute: the water might run out! Simultaneously, on the entire planet. That is, absolutely, absolutely. You don't go to your neighbors to get water into the kettle, you can't wash at the water pump, and you won't be given or sold for any wealth in the world. Have you presented? And How? Not really, right? Well, you can wash and wait. And cook the soup? And simply - a sip of fresh clean water, coming from a workout or returning home from a hot street. Meanwhile, within one day, that is, twenty-four hours, humanity uses - just think for a minute - seven billion tons of water! It's even scary to imagine such a number, not to mention saying goodbye to him forever.

But what can I say - on our planet there are already settlements, countries and even whole parts of the continents where people suffer from lack of water. And rest assured: there they do not use it so thoughtlessly, take care of every drop and very accurately calculate how much and when they will spend it. In order not to have to quickly count every drop of water for all mankind on Earth, it is extremely necessary to save water. Close the taps as soon as you stop using water, use it sparingly for any needs. And, of course, try not to litter any of the reservoirs, be it a river, lake or pond - each of us will have to drink from the same one sometime.
