Everyone has written a composition in our daily study, work and life. An activity, an essay contest, etc. generally require essay writing. After the author submits the manuscript to the organizer of the essay contest, the author's work can participate in the contest, but part of the copyright is also given to the organizer of the essay contest. What is the composition you have read? The following is my collection of short articles about saving water for reference only. Let's have a look.
Water-saving essay 1 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, can dominate nature, can make earth-shaking changes in the world, and can 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.
Ershui is the basic condition for the reproduction of human beings and other creatures, and it is an irreplaceable important resource for human life. There is such a public service advertisement: "The last drop of water of human beings is their own tears!" " "At this point, I seem to see a huge eye rolling down and falling to the ground with a voice. Behind the tears, there are cracked land and dead crops everywhere, and I vaguely hear the painful groans of nature because of thirst and dying.
Some people may think this advertisement is alarmist, but vivid examples add enough footnotes to it. This is a true story: In 2006, Chongqing, a municipality directly under the central government in western China, suffered from drought. At that time, the sun was overhead and cracks appeared in the land. Every crack is thirty or forty centimeters deep and twenty or thirty centimeters wide, so cruel that even the crops bow their heads and people can't get a grain. Someone said, "It doesn't matter if you don't eat or drink for ten days. Not drinking water for ten days is a big deal. " Facts have proved everything: people in Chongqing are thirsty, and some children and old people died because they didn't drink water for several days.
Jinan is known as the "Spring City" and used to be "every spring and Liu Yiyi". There is enough water, and many cities that lack water are envious. But now Jinan, due to the need of building a well-off society in an all-round way, over-exploitation of groundwater has caused Baotu Spring, a famous scenic spot, to stop spraying several times. The fresh and energetic spring water written by Lao She has become a beautiful and painful memory of the spring city, and another water-deficient city is about to appear before our eyes. How do you feel after hearing this story?
As far as I know, China is a country with severe drought and water shortage. China's total fresh water resources are 2.8 trillion cubic meters, but China's per capita water resources are only 2,300 cubic meters, which is a quarter of the world average and one of the poorest countries in the world. However, China, with a population of/kloc-0.3 billion, is the country with the largest water consumption in the world. Someone said, "It doesn't matter to waste a drop of water. We don't lack this. As soon as the tap is turned on, water gushes out. " Is that really the case? No, vivid examples have long denied all this.
Human beings do not cherish water resources and protect ecological balance, and finally taste the bitter fruit they planted. Nowadays, many people drink polluted water and chew polluted food every day. While enjoying modern industrial civilization, people are also threatened by water pollution, resulting in non-digital social and economic losses. This is nature's revenge on human beings, and it is a great mockery of human self-blame!
Water is the source of life and the foundation on which all things live. Saving water and protecting water resources are our unshirkable responsibilities. Let's cherish and protect water resources for the lovely and fragile earth.
In Dunhuang, there is a crescent moon spring. It has a history of hundreds of years, and people praise it as a mirror in the sky. The stars are playing in heaven, which is fascinating. However, with the passage of time, today's crescent spring is not as grand and spectacular as before. Underwater aquatic plants have dried up and died. The fish didn't swim as freely as before, but accidentally returned to the mud pit under the ground, and the water level dropped obviously, and there was a fence around the crescent spring. Now people can't get close to it. This shows the importance of water to animals!
A drop of water may not save a person's life, but it can prolong a thirsty person's life. A drop of water may not fill the earth with spring, but it can save a dry tree.
I learned from TV that there is a 1000-pound chinemys reevesii. In recent days, it has lost its appetite and refused to eat. The staff around were anxious and found the veterinarian. They want to do B-ultrasound for it. But because it is too heavy, even veterinarians can't help it. A few days later, chinemys reevesii died. It died tragically. When the staff dissected. It was discovered that chinemys reevesii's stomach was wrapped in a black plastic bag. It is said that it was because the sea water was turbid and the turtle could not see the food clearly that it swallowed the plastic bag into its stomach, which led to its inability to eat and its tragic death.
Wake up! Terrible human beings! The culprit of this consequence. It's actually you! From now on, save every drop of water, protect the water source and save our friends!
Water is the source of life. It can be said that people evolved from water, and people can't live without water. Once there is no one, human beings will not exist!
Ignorant people please save water!
China is a country short of water resources. Although the total amount of water resources ranks sixth in the world, with an annual output of about 2.8 trillion cubic meters, accounting for 6% of the total amount of water resources in the world, the per capita water consumption is the first in the world. There are 10 provinces, municipalities and autonomous regions in China whose water resources have fallen below the minimum survival line, and the per capita water resources are insufficient 1000 cubic meters. Therefore, China is one of 13 water-deficient countries in the world. So it is urgent to save water!
As we all know, the fresh water resources on the earth are scarce and non-renewable. According to the current means, we can only rely on the advanced treatment of sewage to alleviate the pressure of production and domestic water. In fact, many times, we waste a lot of water resources intentionally or unintentionally. For example, in the summer when I graduated from high school and took the exam in the county, I lived in the dormitory of Northwest Medical Device Factory where my cousin worked. That afternoon, I went to the bathroom. To my surprise, I can not only wash my hands, but also take a bath. What is the reason? The water pipe seems to be broken, and the glistening water is flowing down from the roof, making people have nowhere to live. I had no choice but to take out an umbrella from my room, and soon my coat was wet. At that moment, I was thinking, on the one hand, many places are dry and short of water, and people have no water to drink; On the other hand, we don't cherish water and let it flow. This is purely a human omission. The water pipe is broken and can be repaired, but no one in the factory is in charge, which makes people very helpless.
A few years ago, I went to Taigu Agricultural University and lived there for more than a month. After a long time, I noticed that many students there had little red dot on their faces, probably because of skin allergy and acne all over their faces. I'm confused. At first I thought it was caused by too much oil in my diet. Later, I asked my classmate, who said that the school's drinking water came from the sewage treatment plant there, and it was said that the water contained lead, which led to this result. I'm surprised. I didn't expect this reason. I think, if we can treat clean underground fresh water resources well, why can't we drink advanced sewage? With the waste and consumption of fresh water resources, we will have to pay for it.
When I read an article about water saving in Israel, I was surprised by their cleverness. As we all know, Israel is a very arid country, and 60% of its land area is covered by desert, especially in the south of its border, which is extremely short of water. However, under this natural condition, Israel has made remarkable achievements in agriculture, and its exports of fruits and vegetables account for 40% of the European market. What is even more impressive is that it has become the second largest flower exporter in Europe after the Netherlands. We can't help asking, how did such a water-deficient country create the miracle of turning desert into oasis?
It is said that the per capita annual water consumption in Israel is only 300 cubic meters. For a family of four, the monthly water consumption does not exceed 24 cubic meters, and each cubic meter 1.5 USD. Exceeding this requirement is $5 per cubic meter. In fact, in Israel, every apartment has two water pipes, one is high-grade water for bathing and flushing toilets, and the other is underground fresh water for eating and cooking. Their toilets also have two flush switches to ensure that water is saved as much as possible in different situations. It's really a matter of detail.
When I was traveling on the long and narrow border of Israel, I was surprised to find that there were blue and white pipelines extending in all directions on both sides of the road. He asked his friends around him that there is water more precious than oil. In agricultural production, they take drip irrigation measures and use tiny cracks at the bottom of water pipes to make water flow like plant roots. In this way, the absorption rate of water reaches 95%, while that of sprinkler irrigation is only 75%, which greatly improves the utilization law of water resources. If we use open-air canals to irrigate crops as we do now, they will soon be evaporated and will not reach the roots of plants at all. Later, the Israelis also invented drip irrigation, which provided water, fertilizer and medicine at one time. It was really a multi-purpose and one step in place. This is a clever way for smart Israelis to save water. China # Education Digest "
In addition, they also invented the greenhouse, using the sufficient light, temperature and climate in the desert to grow vegetables in the greenhouse. The greenhouse in Israel is not our ordinary plastic greenhouse. They connect the computer system with the light, temperature, climate, humidity, ventilation and density in the greenhouse to provide the most adequate protection measures for plants at any time. In this way, their greenhouse crops are naturally bumper. Take tomatoes for example. The greenhouse built by Israelis in the desert can yield up to 500 tons per hectare, while the output in the open air is only 60 to 80 tons. This surprised the Israelis to find that miracles can also be created in the desert!
Because dripping water is like oil, they cherish water resources very much and try not to waste them. This rational use of natural resources has created great returns for them.
Look at ourselves again. In my building, we have to pump several plastic buckets of water every day. As a result, due to human negligence, water often flows all over the floor. How can I not be sad? The gardener watered the lawn. For some reason, the ground was full of glistening fresh water, which was wasted. Because I don't cherish it, I become numb and feel indifferent. Anyway, water doesn't cost money, and many people still have this understanding today.
The difference in details cost us too much. Many people create unnecessary waste, so we should really be alert and learn from the Israelis to cherish every drop of water.
Looking at the children in the arid area now, you will burst into tears, and your heart can't bear to waste another drop of water!
Please work together ~ As long as everyone gives a little love, the world will become better!
Drought is merciless, dear friends, as long as we work together, I believe the difficulties will soon pass!
Ignorant people, please save water!
Water used for farmland irrigation is often transported from water sources through channels, ranging from tens of meters to hundreds of meters to hundreds of kilometers. If the canal is earth, some water will leak down during the water conveyance, but it will not reach the field. This water loss along the way generally accounts for 50%-60% of water delivery, and even reaches 70% in some places. What a pity! The land was flooded.
After the water is sent to the ground, how to water it is very learned. Farmers in many places still hold the old idea that watering the land is watering the land, so they have followed the traditional method of thousands of years and adopted flood irrigation. When watering the land, the whole land is full of water. If the land in the field is uneven and low in height, more water is needed to flood the land. In fact, the purpose of watering the land is to get and maintain the necessary water for the roots of crops, but it is completely unnecessary in other places. Deep watering is a huge waste.
Unreasonable packaging fee system
It is probably accepted by most people that water should be paid. However, many places still implement unscientific and unreasonable package charging system. Every household pays the same water fee, regardless of the number of people, not to mention how much water is used. This simple and easy-to-charge practice actually encourages everyone to open water, resulting in a lot of waste of water resources. The same is true for rural irrigation, and the charging system of drinking only "big pot of water" should have ended long ago. Disposable water use
We often hear about the situation. If the production process is backward, the amount of water needed for industrial production is very large. If you use water once and then discharge it, you will consume too much water. Most early factories did this. So far, some small and medium-sized enterprises are still doing this. The advanced method is to improve the production technology level as much as possible, use more water and recycle water as much as possible.
Don't underestimate dripping water.
A drop of water is negligible. But it has been dripping, and the number is considerable. According to estimates, "Didi" can collect 3 pieces in 1 hour. 6 kilograms of water; 2 can be collected at 1 Shuiyue. 6 tons of water. This amount of water is enough for a person's life. It can be seen that there should be no waste at all. As for the continuous small water flow, it can collect 17 kg per hour and 12 tons per month; Roaring "running water" can collect 670 kilograms of water per hour and 482 tons of water per month. Therefore, water conservation should start from a little bit.
Amazing running and dripping
There is a large amount of leakage in the pipeline during water conveyance. According to analysis, due to years of disrepair, the pipeline leaked due to rupture. The leakage rate of urban pipelines is often 8%, and that of factory pipelines is 10%-20%. In some cities in the third world, 60% of tap water was leaked due to rust of water pipes or problems with joints. In Manila, Philippines, the water leakage rate of water mains reaches 58%. In Singapore, which is well managed, the leakage rate of water pipes is only 8%. Managers are negligent and forget to turn off the tap for watering the courtyard, and the formation of long running water has become commonplace. Don't underestimate the dripping caused by the tap not being closed tightly in every household.
Reverse car wash method
Maintaining the good image of urban and rural vehicles such as cars is a sign of civilization, so car washing activities can be seen everywhere. The usual car washing method is to aim a high-pressure spray gun at the car from a distance, and spray water violently from front to back, left and right, up and down to wash away the dust and dirt on the surface. The water falling to the ground quickly flows into the sewer, and it takes more than ten minutes to complete the task. Car washing consumes the same amount of water as a person's daily life. There are 1.2 million cars in Beijing, which consume a huge amount of water every day. Wash away a Kunming Lake in a year. This backward car washing method has three shortcomings: clean tap water is used; Water has not been reused, consuming a lot of valuable water resources; The direct discharge of sewage pollutes the water source environment of rivers.
Yellow river cut-off bright yellow card
During the 27 years from 1972 to 1998, the lower reaches of the Yellow River were cut off for 2 1 year, totaling 1050 days. The most serious is 1997, 13 days, with an interruption of 226 days; At the end of the day, the cut-off river reaches 704 kilometers. The flood of Wan Li will be cut off one day, which is unimaginable to ordinary people. In addition to drought and lack of rain, the decrease of upstream inflow and water storage of water conservancy projects, river siltation, excessive water diversion and poor running water are also factors that cannot be ignored. This is a yellow card warning from the Ministry of Water Resources. Experts and scholars have held a forum to discuss countermeasures.
Does using more water mean a high standard of living?
Some people generally think that using more water is a sign of a high standard of living. This matter should be analyzed in detail. Generally speaking, in the past half century, with the improvement of living standards, the per capita water consumption of the national residents has increased day by day. There are also differences between big cities and small and medium-sized cities, even between the south and the north. But it is obviously unconvincing to say that the living standard in Guangxi is higher than that in Zhejiang and that in Hainan is higher than that in Beijing. Among them, living habits, water source conditions and climate play an important role, and waste can not be ignored. It is the best explanation to look at the huge difference in water consumption of households living in the same building.
On Sunday, I lay on the sofa, singing drinks and watching TV leisurely.
In the picture, a child and his father live in the mountains, and the genius is breaking dawn. The child is carrying a small jar and his father is carrying two barrels. He walked more than ten miles of mountain roads and finally came to a stream. The child and his father were as happy as discovering the new world, and ran to the stream to have a big drink. Then they filled the bucket with water and went home. All the way was bare, and no flowers and trees could be seen again. Back home, it was already dark.
Seeing this, I was very shocked, thinking that I usually only drank half of the mineral water and threw it away; Every time I take a bath, I put a jar of water in it and enjoy it. These things came back to my mind. Water is the source of life. Without water, there is no life, and nothing can survive. We should cherish every drop and don't waste it.
Action is action. I immediately called my parents to the living room for a family meeting.
I said seriously, "Now, China's water resources are getting less and less. So we should save water. My mother pours out all the water for washing clothes every day, which is a waste. My mother can use the water from washing clothes every day to flush the toilet and mop the floor ... so, isn't the water used well? By the way, and dad, I brush my teeth with water every time. When I brush my teeth, the water is still running. In fact, you can brush a glass of water with a cup when brushing your teeth, and the water will not be wasted! "
"What about you?" Mom and dad asked in unison.
"Don't worry, I will take a bath in the future, and I won't waste a drop of water." I'm embarrassed to say.
But I'm still not at ease. I posted a "Save Water" note in the bathroom and kitchen.
Let's take action and start from the dribs and drabs of life. If each of us saves 1 ton of water a year, China1300 million people can save1300 million tons of water a year! In this way, the sky will be bluer, the earth will be more vibrant and you will see more smiling faces.
"It is everyone's responsibility to save water" is a common saying, but how many people have done it?
Students must know that water is the "source of life". Without water, we cannot live and produce. In order to let everyone know the importance of water, let me tell you a set of data! In those areas of the world that lack water resources, one child dies of water shortage every 15 seconds, and 7000 people are drinking unqualified groundwater. How terrible!
Around us, many people are wasting water. I remember once I was absorbed in reading a book. Suddenly, the neighbor's little sister came running happily and said, "Sister, let me get tap water for your home. I want to play water polo. " Before I could speak, she had turned on the tap, poured a bottle of water and played games happily with her partner. Afterwards, I felt ashamed from the bottom of my heart: why didn't I stop them? Don't watch them waste water? Around us, some children like to play with water because they are happy for a while, but they didn't expect that the water resources around us have begun to decrease slowly. We should get rid of this bad habit.
Another thing also shows people's bad habit of wasting water. Once, I saw my neighbor's grandmother carrying water. I asked, "Grandma, what are you doing?" "I'm watering the flowers. Come and water them together. " After that, I came to the garden and began to water the flowers. When I washed all the flowers, it suddenly occurred to me: isn't there a basin of dirty water in grandma's house? Why not use it to water the land? Wouldn't it be more water-saving if everyone reused the washing water at ordinary times?
Humans, hurry to protect our scarce water resources! Otherwise, the last drop of water will be our tears.
Water is indispensable in daily life. For example, use water when washing vegetables, when washing clothes, and even more when you are thirsty. How can we live without water? However, many people do not cherish water. Among our classmates, many students regard water use as a trivial matter. Washing a rag is also washing and washing, rubbing and rubbing, and some simply ask for water to "help", put the mop under the faucet and let the water flush, and the water droplets splash one meter away from the faucet; Others turn on the tap and tap water becomes "self-flowing water" and "constant water". Don't countless water charges also flow to the sea of Wang Yang?
You know, water doesn't "come by itself". A drop of tap water has to go through a series of production processes, such as pumping, sedimentation, filtration, disinfection and water delivery, before it can "come" to users. How much hard work the workers have to pay! We don't cherish water now, are we worthy of comrades who produce water? You can really say, "Who knows that it is difficult to control water?" Isn't it a crime if we use water without restraint? Although the country is very developed now, we should carry forward the fine virtues of diligence and thrift and make them play a greater role in the construction as much as possible. Don't think that thrift is stingy, rustic and generous. Diligence and thrift is also an important embodiment of one's ideology and morality.
I hope everyone will make a mountain out of a molehill on water saving and develop good water saving habits.
