All living things need water, and they can't live without it. Although there is a lot of water in Hangjiahu Plain, everyone will not be rare.
No one will feel distressed because of lack of water. In fact, some areas of our country are very short of water. Now, isn't the South-to-North Water Transfer Project under way? Xinjiang, Inner Mongolia and other places with little water have become deserts.
Water, we should all take it as something as important as our own life to protect. I remember once, I saw a public service advertisement on TV, which told a story.
The story tells that there was only one drop of water, and everyone rushed to buy it. So, someone proposed to hold an auction and sell the last drop of water.
At the meeting, people bid one after another, one higher than the other, and some people paid sky-high prices. No one can pay more money than him. At this time, the whole audience was silent, some were trembling, some were crying, some were giggling ... Because there was no water, they would all die.
I am very interested in this public service advertisement. I really admire the person who made this advertisement. It's really ingenious, let us all know that water is priceless.
Since that day, I have been saving water without any waste. So, now, I want to tell you through the article, so that everyone knows the importance of saving water.
If everyone saves water, then all living things can live healthily and make the whole world so beautiful. Hope to adopt.
2. About the importance of water composition 400 words water resources
Cherish resources and protect the environment, we can start from the small things around us, such as not littering, saving water and electricity resources and not using disposable goods. These are all ways to cherish resources. As long as we have perseverance, we will certainly become small pacesetters who cherish resources.
If most people destroy the environment, then the country needs a lot of resources to manage the environment. This requires not only a lot of manpower, but also a lot of material resources. However, if we all become ambassadors to protect the environment, then we will not only save resources, but also save manpower and material resources. Who wants to waste resources? If most people waste water resources, then there will be no water to drink in the future, even if there is water to drink, it is very precious. A newspaper once said that in about 70 years, water will be more expensive than oil.
Water, the basic substance on the earth, deserves our praise! She gave birth to the world and all sentient beings; It is she who provides energy for life and makes life survive; Or did she let life develop continuously and become more and more prosperous? Therefore, it is no exaggeration to say that "water is the source of life".
If people do not cherish water resources, then the last drop of water in the world is people's tears.
But is water inexhaustible? We can definitely answer: No, although 70.8% of the earth is covered with water, 97.55% of the water is seawater, which can neither be directly drunk nor irrigated. Of the remaining 2.5% fresh water, the water that humans can really use is less than 1% of the global total fresh water. It is true that from the appearance of primitive life on earth to the present, water has been serving life, working hard and never stopping. But I don't know if you have thought that there is a limit to the endurance of water, and now water resources are in short supply!
About writing "water", if you write about the importance of water, 300 to 400 words, the second day of water-the source of life.
Water is the source of life. Without it, everything will cease to exist. Water is the most needed substance for human beings. Without it, mankind will also face extinction. It can be seen that water is closely related to our life.
The ancients thought that water was an inexhaustible gift from heaven, but facts speak louder than words. According to statistics, the global fresh water resources are only 350 million cubic meters, and only 0.34% of this limited fresh water resources can be used by human beings. Due to uneven distribution and waste of life, 60% of the world is short of water, which is serious and the situation is grim.
At present, China is also facing a huge water crisis. In addition, the number of people has gradually increased, and the water supply has also increased. In addition, the severe drought in recent years has led to frequent water cuts. Many vegetable fields planted by farmers died because there was no rain irrigation, and the national vegetable production decreased to the extreme. But people still don't realize the importance of water, and they still waste it at will.
On the way to school, I often see a hotel worker washing vegetables, only to see him turn on the tap at full speed, put the vegetables under the tap and leave. It was a long time before he came back to take the food away, but he didn't turn off the tap, and a lot of domestic water flowed into the drain pipe, which caused great waste.
In the past, we could always see Qingshui River wandering in the river. Now, what we see is a garbage river full of garbage and industrial waste. With the development of modern science and technology, there are so many abandoned industrial wastes that even the ponds in the park are doomed. In this way, the survival of mankind is more threatened.
Faced with such a huge threat, we should learn to save. If each of us saves a glass of water, the world will save the next river. How many rivers and seas will we save in the long run!
Protect the blue sky and blue sea and create a beautiful home. Let's join hands to contribute to the protection of water resources and lend a helping hand to national construction.

4. The importance of water composition 300 words 1 ... Water plays an important role in our life, it is the source of life and one of the most important and indispensable material resources for human survival and development.
People cannot live without water for a moment. Water is the most important substance in people's lives. The physiological functions of human body are varied, and all chemical reactions in the body are carried out in medium water. Without water, nutrients cannot be absorbed. Oxygen can't be delivered to the needed parts; Nutrients and hormones cannot reach their functional sites; If waste cannot be eliminated, metabolism will stop and people will die.
Therefore, water is the most important substance in human life. On earth, where there is water, there is life.
All life activities originate from water. Water in human body accounts for about 65% of body weight.
Among them, the brain water content is 75%, the blood water content is 83%, the muscle water content is 76%, and even the hard bones contain 22%! Without water, nutrients in food can't be absorbed, waste can't be excreted, and drugs can't reach the effective parts. Once the human body is short of water, the consequences are very serious.
Lack of water 1%-2%, feeling thirsty; Lack of water 5%, dry mouth, wrinkled skin, unconsciousness, and even hallucinations; Water shortage 15% is often more than hunger. Without food, people can live for a long time (some people estimate that it is two months). If there is no water, they can live for a week at most.
2. In modern industry, there is not an industrial sector that does not use water. There is no industry that is directly or indirectly incompatible with water.
More industries use water to cool equipment or products, such as steel mills. Water is often used as a detergent, such as washing raw materials or products, cleaning equipment or floors. Every factory should use various functions of water to maintain normal production, and almost every production link involves water.
Therefore, water, as a precious wealth endowed by nature, has long been concerned by people. However, people often use the word "water resources", but it has been nearly a decade or two.
There are dozens of definitions of water resources, and the common one refers to "the amount of water that can be frequently used by people and recovered year by year". It is also commonly called fresh water resources.
In this way, bitter and salty seawater is not included, and even glaciers that have been difficult to melt for thousands of years and some inaccessible groundwater are excluded. In the final analysis, resources are the most clearly understood by human investigation, and will never change their quantitative structure and distribution with new discoveries like coal, iron and oil.
The value of water resources lies in its demand for life on earth and its ability to serve mankind, including power generation, shipping, aquaculture and environment. As we all know, water is an extremely important and active factor in both natural environment and social environment.
Beautiful scenery, birds and flowers, good weather and good harvest are the beautiful scenery that human beings pursue and yearn for, and also the fruits of human labor creation and careful care. Water is constantly flowing, which makes the world full of vigor and vitality in human body, farmland and factory. Dirt is carried away by the current, diluted, dissolved and purified by nature.
When we wander in the embrace of nature, what we are actually facing is the power that water gives us. In our mountain life, water accounts for a large proportion. The earth is called "water polo" The phrase "three mountains, seven waters and one field" vividly summarizes the situation on the earth's surface.
According to authoritative estimates, the water storage on the earth is 385 million cubic kilometers. If these layers are spread on the earth's surface, the earth will become a "water polo" with an average water depth of more than 2700 meters. Sailing in the sea, although the waves lift you up and play with you, you dare not drink any seawater, even if your lips are chapped with thirst.
97% of the water on the earth is this kind of seawater that humans can't drink directly at present. Water plays an important role in our life. It is the source of life and one of the most indispensable and important material resources for human survival and development. People cannot live without water for a moment. Water is the most important substance in people's lives.

5. A 500-word composition about water is mainly about important water, which is the source of all life. It is because of water that this beautiful blue planet exists, which makes human beings, animals and plants survive. What if there is no water? Then the earth will be as lifeless and lifeless as Mars and Saturn. Then, there will be no humans, trees, flowers and other things. Flowers will bloom only if they are watered, and green leaves will be beautiful if they are moistened. Will the flowers bloom if there is no water? Can the stream sing? Can birds fly? Will the young trees flourish? The answer is self-evident. Water resources are limited. There are very few fresh water resources on land. Although the earth's surface is covered with 70% water, most of it is seawater, which is salty and cannot be directly used. However, fresh water resources only account for 2.53% of the total water bodies on the earth, and nearly 70% of them are solid glaciers, that is, alpine glaciers distributed in polar regions and low latitudes, which are still difficult to use. At present, it is relatively easy for humans to use it. It is mainly river water, fresh water lake water and shallow groundwater, accounting for about 0.3% of the world's total fresh water reserves and only 7/100000 of the world's total water storage. In daily life, water is always wasted unconsciously. Washing vegetables requires basin by basin. If you turn on the tap, a meal will consume 50 kilograms of water. Washing clothes with a full bucket of washing machine will consume 65433 more water. Washing with clean water can not only save water, but also effectively remove pesticide residues on vegetables. Wash the water and mop the floor, then flush the toilet. Wash the doors and windows, furniture, shoes and socks for the second time. Flush the toilet after defecation and make full use of the used "dirty water". If you turn off the tap and wipe the soap in the shower, you can save 60 kilograms of water in the shower. And washing water is used after washing. When cleaning bicycles and family cars, do not rinse them with water, but wipe them with a damp cloth. In places that are too dirty, you should also use the water left after washing clothes. Water the flowers at home with rice washing water, tea and washing water. And use a small amount of water to wash towels, small objects and fruits at home. It is recommended to hold water in a washbasin instead of turning on the tap to wash them. If everyone has no awareness of saving water, if it really arrives, cherish water resources, protect water environment and sewage treatment system, strengthen water environment monitoring, strengthen legal awareness, manage water resources and water environment according to law, and save water, which will benefit the present and future generations. Therefore, I call on everyone to save water. From now on, save water, cherish water, cherish water resources and protect water resources. Start from me, start from bit by bit.

However, if you always drink a glass of water at meals or immediately after meals, your stomach will be damaged. If you always collect a lot of water and drink it quickly in one day, it will not help you to have a healthy life. If you often use drinks as water to supplement the water needed by the human body, then you are not far from losing weight.
Drink the right water and good water, so that we can live a healthy and happy life.

Try not to use clean water, and use washing water after washing. When cleaning bicycles and family cars, use wet cloth instead of water. Where it is too dirty, it is also advisable to wash it with the water left over from washing clothes. Water the flowers at home with rice washing water, tea, laundry water, etc. Household washing towels, small objects, fruits and other small amounts of water. It is better to hold water in a basin than to turn on the tap to flush it.
If everyone has no awareness of saving water, if water is really as expensive as oil, countless people will die of thirst, and the last drop of water on the earth will become a tear that people regret!
Cherish water resources and protect water environment. Sewage treatment system, strengthen water environment monitoring, strengthen legal awareness, and manage water resources and water environment according to law.
Saving water is beneficial to the present and the future. Therefore, I call on everyone to save water, save water from now on, cherish water and cherish and protect water resources. Start from me, start from the side bit by bit!
9. A 500-word composition about water. Because of water, the seeds of life have a hotbed of survival.
Life keeps sprouting, continuing and evolving, making the earth full of vitality. Water, in the form of life, slowly flows through our bodies.
Water is a person, and people are also water. Water flows in the human body and people live around it. Man is the heart of water, and water is the backbone of man.
In the dark, we are doomed to be inextricably linked with water. Laozi once said: "There is nothing softer than water. The strong can't win, because it's not easy. The weak wins the strong, the soft wins the strong, and the world is inferior."
Water is so fragile that it can easily disappear without a trace in the warm sunshine. However, water is very powerful.
Look at the dripping spring in the cave. After countless struggles, the weakest water can also run over hard rocks. Watch the water rolling down from the high cliff, like a mountain crashing thunder.
The momentum was overwhelming and the mountains and rivers were swallowed up with a bang. Look back at people, so do people.
Pascal, a French thinker, once said, "Man is the most fragile thing in nature. One breath, one drop of water is enough to kill him. " . However, man is still much more noble than what killed him. "
Man can be easily destroyed, but he has the same great power as water, which can dominate nature, make the world change dramatically, and even destroy the whole earth. Water is selfless, she is the source of life, and she has raised countless lives in the world with herself.
However, she didn't ask for anything in return, but silently and selflessly dedicated herself to human beings and creatures. I really hope that my river of life can flow like water, and the place where it flows is a harvest place for picking the fruits of dreams.
Perhaps in the vast sea of people, I am a negligible drop of water, but I hope I can reflect the brilliance of the sun.
