Water is the source of life speech 1 water, the source of life, human beings can't live without water all the time.
Although one third of the earth's surface is covered with water, the total amount of water resources is very large, but 97.5% of it is seawater, and only 2.5% is water. In this limited water resources, 90% are ice sheets, glaciers and ice and snow in the North and South poles beyond human reach. In addition, a certain proportion of deep groundwater resources are difficult to use. Therefore, at present, the water resources available to human beings are quite limited, accounting for only 0.26% of the total global water resources.
On campus, some students run around in the flower beds with water guns, chasing and fighting; At the entrance of the canteen, some students turned on tap water, but forgot to turn on the tap. When they gloat, have they ever thought that they may waste insignificant water, but there is hope to save several lives? I always listen to my classmates complaining about why the water is cut off again. In fact, we all know who is important, and we lack the knowledge to do this little trick of tightening the faucet.
Today, people still often admire that the greatest invention of thousands of years is that mankind finally flew into space in the last century, looked back at the earth and appreciated this "sapphire" embedded in the darkness of the universe. It is water that gives the earth soft blue light and a beautiful home. March 22nd this year is the19th World Water Day. Please let us cherish, save and protect water like stunners.
Thank you!
Water is the source of life Speech 2 Dear teachers and students:
Hello everyone!
Water is very common in our life, but many living things can't live without water. For example, flowers and trees around us, all kinds of birds and animals need water resources, and we humans can't do without water resources.
Seemingly ordinary water has different meanings for us. They are the source of our life and the necessities of our survival. I hope every student can cherish water resources, not wasting or polluting. Maybe we don't feel short of water now, but there are many places that are short of water, such as deserts. Because of the serious water shortage and no vegetation, Wan Li is uninhabited and sees endless yellow sand. Due to lack of water, many deserts have become forbidden areas of life, and water is too important for us.
Around us, we can see clear rivers and streams, beautiful lakes and mountains. Although water resources are abundant, we can't squander them at will. There are many creatures in the water, and all kinds of fish depend on it for their livelihood. However, pollution has appeared in many places now. The clear river turned into black and smelly black water. Near the polluted river, aquatic life has disappeared and the surrounding trees have withered, because there are too many harmful substances in the sewage.
The water resources available to us on our planet will not increase because of the increase of our population, but will decrease because of the increase of the number of people, because water resources are limited, not endless, and will be exhausted one day. Although water resources can be recycled, they also need to be filtered by nature. However, when a large amount of water resources are polluted and the source of life on which we depend is reduced, it is very serious for us. Because there is not enough water, we should cherish water.
In normal times, if we can save water, we must save every drop of water. Many people, limited water. At the same time, we should also supervise the discharge of sewage. Don't directly discharge the sewage and domestic water from factories into rivers and lakes, because nature has its limits and the purification ability of ecosystems is limited. We should treat sewage in time instead of directly discharging it into nature and protect water resources, because water is the source of our life and we can't live without it.
Students let us take action, let us cherish and protect water resources, and also start from us, do not waste water resources, save every drop of water in life, cherish every water source, maintain the virtue of thrift, and leave the source of life to more people. Although we are ordinary, we can cherish water resources. I hope students will remember the importance of water resources, don't waste them, and protect them firmly forever. Water is life.
Thank you!
Water is the source of life Speech 3 Water is the source of life. As the saying goes, "People can't eat or drink water for a day". "Human life is inseparable from water, and water is an indispensable and important resource in human life".
According to the data, the fresh water resources that can be directly used by human beings account for 0.3% of the earth. Most parts of the earth are seriously short of water, and many trees, villages and fields are swallowed up by the desert, so the area of the desert is gradually expanding. The reduction of fresh water resources has seriously affected human economic construction and threatened human survival. Saving water and resources has aroused great concern of mankind.
However, in our life, the phenomenon of wasting water resources is serious. Around us, the waste of water resources is amazing. I noticed some tap water faucets, some of which are broken, and the water is still flowing, and some faucets often drip, so I don't know how much tap water is wasted. Many families seem to be saving water, but in fact they are wasting water resources. In some families, tap water drips into the water tank all day long in the kitchen and bathroom, but the water in the water tank and storage bucket keeps flowing into the sewer. Some families directly pour some completely usable water, such as vegetable washing water and face washing water, into sewer basins in pots. Look at all this wasted water. If you drop by drop all the year round, you will lose 1 ton of water, which is really incalculable. Calculate it carefully, and the result will make you dumbfounded! !
While we are wasting water, we are also polluting our water source, so that the polluted water of urban life and industrial wastewater are directly discharged into the river, so that the river water can no longer be used.
Everyone saves water, cherishes and protects water resources, and gives us a beautiful living environment with lush trees, flowers and birds, clear rivers and happy fish! !
Water is the source of life Speech 4 Dear Mayor:
Hello!
"Building a conservation-oriented society" is our slogan of cherishing and saving resources. However, how can we really save resources? Why do you strongly recommend saving? Please listen to my heart below!
Let's start with water resources. The total amount of water resources in China is about 2.8 trillion cubic meters, ranking sixth in the world. The per capita water consumption is more than 2 100 cubic meters, accounting for only a quarter of the world's per capita level. It is a country short of water, and more than 400 cities in China are short of water. In particular, the water shortage in the western region is very serious, and it is very difficult for people and animals in some mountainous areas to drink water.
Water use in China is facing a serious problem, so we should cherish water resources and save water. For example, after running out of water, tighten the faucet to avoid the waste phenomenon of "one river of clear water flows eastward" If the faucet is found to be broken, it should be repaired in time to avoid a lot of water loss. Don't underestimate the discarded batteries, because a button cell will pollute 600 tons of water. If it is thrown into the water, the water can't be drunk. We should collect the batteries and send them to the recycling station, which can not only avoid polluting the water source, but also recycle the batteries, killing two birds with one stone. You can't just talk without practice, you have to act!
Be sure to save water: Beijing, as the capital, has only 300 cubic meters of water resources per capita, which is only 1/8 of the national average and 1/32 of the world average, with an average annual sewage of 2.3 billion tons. Serious water shortage is a huge problem facing this city, and water saving is imminent. The main reasons of water shortage in this city are the lack of water resources, insufficient capacity of urban water supply equipment and serious water pollution. Nowadays, more and more Beijing residents have become car owners, and car washing has become an indispensable part of life. But car washing will consume a lot of water, especially roadside car washing. If recycling facilities are not used, water will be seriously lost and wasted.
It is Mother Earth who brings us one beautiful spring after another. On April 22nd, when the 37th "Earth Day" came to us with the footsteps of spring, we couldn't help thinking about how to treat Mother Earth well and how to cherish the spring scenery in Wan Li given to us by Mother Earth.
Be kind to the earth-cherish resources and sustainable development are the themes of this spring.
However, the current situation of protection, utilization and sustainable utilization of land resources and mineral resources in China is not optimistic. We have to ask: is the spring of the earth forever?
"Cherish resources and advocate economy" is the obligation of every citizen. For our better tomorrow, please act quickly!
Water is the source of life. Today, people still admire it from time to time. One of the greatest discoveries in thousands of years is that mankind finally flew into space in the last century, looked back at the earth and enjoyed this "sapphire" embedded in the darkness of the universe. It is water that gives the earth a soft blue light, so that human beings who live in seclusion on the earth can enjoy the vitality it breeds and the hope it creates.
Water is an indispensable and irreplaceable important natural resource and environmental factor for all life and social and economic development. However, with the rapid development of population growth, industrial and agricultural production activities and urbanization in modern society, the limited water resources and water environment have been greatly impacted. On a global scale, the pollution of water quality, the sharp increase of water demand and the unreasonable utilization caused by competing development among departments have further shortened water resources, worsened water environment, seriously affected social and economic development and threatened human welfare. 1993, the United Nations General Assembly designated March 22nd as World Water Day every year, and tomorrow will be 18 World Water Day with the theme of "Urban Water Resources Management".
China is a country with serious water shortage, and the per capita river runoff is only 1/4 of the world average. China has 668 established cities with a total population of 379 million. However, compared with the rapid development of cities, urban water conservancy construction is still lagging behind and water resources are obviously in short supply. More than 400 cities in 668 established cities are short of water, and more than 1 10 cities are seriously short of water. In addition, the water environment is deteriorating. Nearly 50% of river sections and more than 90% of urban waters in China are polluted to varying degrees. Serious over-exploitation of urban groundwater leads to ecological problems such as continuous decline of groundwater level, land subsidence and seawater intrusion. Therefore, starting from 1994, China designated March 22nd to 28th as China Water Week.
Although Shanghai is located in the south of the Yangtze River, it is still a water-deficient city. Only 1% of Shanghai's surface water meets the national drinking water source standard. As middle school students, we should realize that water is of special significance to us in such an international metropolis. On the occasion of World Water Day, on behalf of the Student Union, I propose that everyone should use their own practical actions to save water. Let's start by cherishing every drop of water, and don't let the last drop of water become our tears!
My speech is over, thank you.
Water is the source of life speech 6 teachers and students:
The topic of my speech under the national flag today is water, the source of life.
March 22nd every year is World Water Day, and the week of March 22nd every year is designated as China Water Week. Water is the source and foundation of life, and human health comes from water first. People can go without food for several days, but they can't go without water for several days. Now, there are 2 billion people in the world who are seriously short of water! Every year, 50 million children die from drinking unclean water! How shocking this figure is! The water crisis has sounded the alarm for mankind! Saving water and protecting water resources are serious problems that we must face now.
What is more noteworthy is that from the end of last year 10 to today, there has been a large-scale drought in Yunnan, Guizhou, Guangxi and Sichuan, which has lasted for nearly five months. According to the statistics of the National Defense General Office, as of March 20th, crops in five southwest provinces (autonomous regions and municipalities) such as Yunnan, Guizhou, Guangxi, Chongqing and Sichuan suffered from drought of 56.68 million mu, with about 50 million people and 610.20 million livestock suffering from drinking water, which is a once-in-a-century drought. Therefore, it is urgent to protect water resources, which is also the obligation of every citizen in China. Although we may not feel that we are short of water, you should think about the people in Yunnan-Guizhou area. Many people are worried about draught.
Please think about this scene: an old man used a thick rope to slide his seven-or eight-year-old grandson into a deep well, just to scoop up a ladle of slightly turbid water. When a mother is boiling water in a pot, there is white alkaline sediment all over the pot. Think about this scene again: just to wash a towel, we washed water, and many similar behaviors often happen to us. The water crisis is not far away from us. Saving water and protecting the environment are the most basic tasks for each of us.
World Water Day is a time when the earth warns people to use water: it tells people that water breeds and maintains all life on the earth, and human society cannot exist without water.
Let's take a look at the things around our classmates. Some of our classmates have a bad habit. After washing their hands, they don't tighten the tap and throw the garbage into the pond. Imagine that if each of us is the protagonist, then a lot of water resources will be wasted and polluted. If a lot of water resources are wasted, how can we survive?
Teachers and students, let's join hands and use our practical actions to save water and protect water resources! I believe that through the joint efforts of all of us, we will be able to do these things within our ability. Don't let the last drop of water in the world become our tears.
My speech is over, thank you.
Water is the source of life Speech 7 Dear teachers and students:
Hello everyone!
I'm Lai Qi from Class Four, Grade Five. Today, the topic of my speech under the national flag is: protecting the source of life-water.
As we all know, water is the source of life, and the global fresh water resources only account for less than 3% of the total water of the earth. And nearly two-thirds of them are hoarded in the thick snow and ice in mountainous areas and polar regions, and nearly one-third are buried deep in the stratum. The fresh water that can really be used by us only accounts for about 0.26% of the total water of the earth. Fresh water resources are so scarce, and the seawater, which accounts for 90% of the earth, is bitter and salty, so it can neither be drunk nor used. If seawater can irrigate crops, it will also lead to the rapid death of crops. If seawater is used to burn the boiler, scale will form on the boiler wall, which will affect heat transfer and even cause explosion.
Groundwater is mainly used for our life, work and farmland irrigation. Underground water is hidden underground, which is not exposed to sunlight and the temperature is relatively stable. If you accidentally let some pollutants seep into the ground, it will stay there for a long time and pollute the groundwater for a long time. Because groundwater is not as easy to wash away pollutants as river water.
Most of the groundwater has been infiltrated. The soil layer near the ground is loose and porous, so the rain, snow water and water vapor on the ground will penetrate along the gap. There is less rain on the ground, and there must be less groundwater. So groundwater is hard to come by. We should start with saving a drop of water and protect water resources. According to scientific calculation, if "dripping water" keeps flowing, 1 hour can collect three. 6 kg of water, 1 month to 2. 6 tons of water. This amount of water is enough for a person to meet his needs for half a year. Obviously, every drop of water should not be wasted.
In order to save water resources better, I think we should do the following:
First, we must protect the water source. Don't throw garbage into rivers and lakes to prevent water resources from being polluted.
Second, we should use water rationally. In life, the water after washing your face can mop the floor, the water after washing clothes can flush the toilet, and the water after washing vegetables can water the flowers. After reusing water, you must save a lot.
Third, we should save water. Advise mom and dad not to wash the car often, twist the faucet, and the faucet should be repaired or replaced in time.
As a primary school student, although we can't do great things to save water, we can start from ourselves and convince people and friends around us to do the above. Finally, I propose to all the students again: please save every drop of water in your life. Clear water and water drops are precious. I believe that as long as we all cherish the water resources on which we live, our tomorrow will be better!
My speech is over, thank you!
Water is the source of life Speech 8 Teachers and students:
Hello everyone!
The theme of my speech today is water, the source of life.
Nowadays, as we all know, China is a country with serious water shortage, especially in Taiyuan, where water resources are extremely scarce. How to rationally utilize and develop water resources is the responsibility of each of us.
Speaking of water, we are no strangers. Almost all of us have been using water. Someone has done such an experiment, saying that it is more important for people to eat or drink water. The result is obvious. Natural water is more important, which reminds me of the word "alive". As we all know, literally speaking, there is water beside the tongue, and there is life with water. China's population is 654.38+0.3 billion.
Water is the source of life. When we open the long river of history, we can easily find that rivers are distributed in four ancient civilizations. Yes, only with water, only with the dew given by God, can our life be extended and our wisdom be broadened. The ancients said that "mountains are like water", who is beneficial to everything without competing with anything, water is noble.
We often say, green mountains and green waters. With water, our world will be beautifully dressed. With water, flowers and plants will begin to bloom luxuriantly and brilliantly. With water, fish will be active between the sea and water, adding infinite vitality to this beautiful world. With water, there will be a vibrant scene in which eagles strike the sky, fish are shallow and flowers are numerous, and everything is magnificent ...
What would the world be like without water?
We all know that when we write with a pencil, we can erase our mistakes, but when we use water, if we make mistakes, we can't repent, because water is a non-renewable resource!
Water is the source of life. Save water, starting from me, starting from now, starting from the side, starting from small things, not saving national water resources, starting from small things around, putting an end to the phenomenon that water pipes run, run, drip and leak, washing vegetables with rice washing water, washing feet with face washing water, storing waste water to flush toilets and so on. As long as we can do a lot.
Water is the source of life Speech 9 Teachers and students:
Hello everyone!
The topic of my speech today is: water, the source of life.
Water is the origin of life. Water is the foundation of survival. Water is a valuable resource. Water is not only indispensable to life, but also an all-encompassing cultural existence: the inspiration of artists.
Sources, the focus of scientists' research, and the indispensable elements of religious ceremonies of many traditions and beliefs.
Student: You must have seen such a public service advertisement: there is a faucet on the TV screen, which is dripping with difficulty. The dripping speed became slower and slower, and finally the water was used up. Then a pair of eyes appeared on the picture, and a tear flowed out from it. Followed by this sentence: "If human beings don't cherish water, then the last drop of water we can see will be our own tears."
China is a developing country. With the continuous development of social economy, many factories have been established. These factories often discharge sewage into rivers. As a result, the water in many river basins was destroyed and could not be drawn. Water has a great influence on the earth and its residents, and it is indispensable for people in families, factories and rural areas. More than two-thirds of the human body is water, so we should drink water every day to replenish the water lost during sweating and breathing and keep healthy.
March 22nd is World Water Day. Every year on this day, all countries in the world will publicize that everyone should cherish water resources and protect the water of life. In fact, it is not only this day, but every day in our life should cherish every drop of water and cherish the water of life with practical actions!
Water is the source of life. With water, there are clear rivers and blue oceans. With water, there are plants, animals and humans on the earth. In fact, nothing in nature can exist without water. So we should save water.
Students, we can't live without water. If we don't save water, what should we do when water resources are exhausted? Where can we find water and where is the hope of life? Let's act together, save every drop of water, make the source of life inexhaustible, and make our society a "harmonious society of people and water!"
Thank you, my speech is over.
Water is the Source of Life Speech 10 Dear students:
"Water is the source of life, and we should protect every drop of water." This sentence is true, without water, the surging Yangtze River and Yellow River will be cut off, and those dotted lakes will dry up; If there is no water, human beings will disappear; Without water, our beautiful world would not exist.
On earth, where there is water, there is life.
All life activities originated from water, and secondly, water also contributed to crops.
One kilogram of corn is watered with 368 kilograms of water; Similarly, wheat is 5 13 kg of water; Rice is as high as 65,438+0,000 kilograms of water ... Today's bumper harvest in agriculture and orchards is attributed to "water".
Now many families have bought cars, and in order to keep them clean, they spend money to wash them.
Whenever I pass by the car wash shop and see the clear fountain-like water flowing along the traffic and wasting on six roads, I will think of the scene that people in water-deficient areas are eager to drink water.
I think: if these people carry a bucket of water and scrub it with a towel, how much water will they save? How many children who lack water will be bathed?
So, class, let's turn off the tap after washing our hands. Turn off the tap when brushing your teeth ... I remember the science teacher said that if the water on the earth is compared to a bowl of water, there is only one spoonful of fresh water for people to drink, so let's protect this spoonful of water from now on.
Because of this spoonful of water, we will see the earth as a landscape painting; Ten thousand kinds of crops will be stored; We will have the best life.
