I believe everyone knows that "water is the source of life", and each of us can't live without water.
However, there are few fresh water resources on the earth, accounting for only 2.7% of the total water resources on the earth, so the earth is very short of water now. Although we know that water resources are precious, we are still wasting water. Because we don't lack water now, we don't know how to save water, but do you know how those people spend it in those places where water is extremely scarce? They use the water washed in the morning to wash rice for cooking, and then take some water to drink, which means that only a small basin of water is used every day. Do you know how hard these days are?
Therefore, we should protect water resources and prevent water pollution, starting from the small things around us. For example: save water and use phosphorus-free washing powder. ...
Everyone must understand this kind of public service language! If humans don't save water, then the last drop of water on the earth will be human tears. After listening to my speech, you must feel something! Then let's act quickly!
Speech on saving water resources 2 Dear teachers and students:
Hello everyone! The topic of my speech today is: saving water resources.
Water is the source of life and the foundation of life. Our 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! In other words, water is the foundation of life for 2 billion people. The water crisis has sounded the alarm for mankind. Saving water and protecting water resources are the top priority now!
There is a saying: Don't let the last drop of water on the earth turn into human tears. I believe that this is not only my personal wish, but also the wish of hundreds of millions of people!
There are not many fresh water resources on the earth. In the past, many people thought that water, like air and sunlight, was an inexhaustible natural resource, but it was not. Although two thirds of the earth is water, 97% of the water is ocean. As we all know, seawater is salty and can't be eaten by human beings, and the remaining 3% fresh water is mostly concentrated in the cold north and south poles, so the water resources available for human beings on the earth are even less.
Therefore, I propose: save water resources and protect the environment!
That's the end of my speech, thank you!
Water is the source of life and is necessary for all kinds of life. What would it be like without water?
Through my research, I know that water in the human body is also very important. The water content in adult men is 60%, and that in adult women is 50%. Among them, the plasma water content is 9 1%-92%, the muscle water content is 76%, and the bone water content is 23%. Water shortage is more serious than hunger. Human body is short of water 10%, and life activities will be seriously unbalanced. Water shortage of 20% will lead to death. At present, the annual water consumption of mankind has reached 7 trillion cubic meters. Water consumption will increase by 5% every year. Every fifteen years, global consumption will double, and now there are more than 100 countries and regions in the world that are seriously short of water, which has endangered the water use and survival of 2 billion people.
After reading the above information, it gives me the creeps. I didn't expect our beautiful life today to be hard-won. I think what will happen to everyone if there is no water here! Not only can it not survive, but it will also affect all living things. In the desert without water, life is very scarce, only some insects, grass and no higher animals. However, across the desert is the sea. The sea is full of vitality. There are fish and microorganisms in the water, and corals, sea cucumbers and octopus on the seabed. Most species on the earth are in the ocean, and there are many creatures in freshwater lakes. If there were no lakes and oceans, more than half of the living things would be extinct.
Therefore, whether it is seawater or fresh water, we should protect, cherish and cherish it.
Speech on saving water resources 4 Teachers and students:
Good morning!
I come from Class Two, Grade Four. The topic of my speech today is: saving domestic water and protecting water resources.
Water is the source of all life. With it, the blue planet was formed; With it, the whole world has the breath of life; With it, our world becomes full of vitality; With it, we have beautiful mountains and rivers, clear streams and blue oceans ... With it, we have everything.
Each of us must improve our awareness of water conservation and start from scratch. For saving water, students always feel less important than saving other things. Some students turn on the tap, wash their feet and wash their children. Some students don't drink boiled water, but drink tap water with their mouths to the faucet. The sound of water doesn't hurt at all.
Is water really not worth it? Is it really unimportant to save water? Don't! 93% of the water in the world is salty and can't be drunk. Fresh water only accounts for 7%, and drinking water only accounts for 0% and 8%. The world's 5 billion people depend on drinking this 0.8% fresh water. Look, how precious water is!
Although three liters of water per person per day can sustain life, in fact, every urban resident has to cook, wash clothes and wash vegetables every day ... everything can't be separated from boiling water, and it takes hundreds of liters of water. In addition, with the improvement of living standards, air conditioners are generally installed in people's homes. In the process of using air conditioner to cool down, there will be water dripping. If you use air conditioning at night, the dripping water will be connected to a bucket, several kilograms. This water is often wasted. Is it possible to lead the air-conditioning drip pipe to the balcony or home and connect the water to the bucket and washbasin? This method can be used by families, enterprises and institutions with air conditioning. If we make full use of air conditioning to turn waste into treasure, the water saved will be an amazing number. In addition, agriculture and industrial production are inseparable from water. For example, steelmaking and steel rolling only need water cooling; In order to maintain a certain temperature and humidity, the textile workshop needs to adjust the moisture; Building construction is inseparable from water; Paper-making, power generation ... Food, clothing, housing and transportation, which can be separated from boiling water?
People can live without food for several days, but they can't live without water for several days. Humans can't live without water, which shows how important it is to save water.
Water is the source of life, and lack of water is more than anemia. A drop of ordinary water moistens the innocence of life. Thanks to water with a pious attitude, it always stirs water-saving notes in the ordinary. Let's appeal to people with sincere voice: save water, and you will shape a life! Save water, you will have more precious space! Save water, the blue planet where we live will still flow, with the magnificence of "flying down thousands of feet" and the poetic meaning of "flowing water over a small bridge"! Protect water resources, starting from you and me; To save water, we should start from the small things around us. Let's cherish the water of life, be proud of saving water, turn off the tap at hand and never let the water run empty. As long as we always have the consciousness of saving water, we can use more water, so that the water after washing vegetables, washing rice, washing clothes and washing hands can be used to water flowers, flush toilets and clean floors ... If we can persist for a long time and develop good water-saving habits, then everyone will make due contributions to saving water, protecting water resources and protecting human homes!
Cherishing water means cherishing life. Only when everyone cherishes water can human society be endless; Only when everyone cherishes life can mankind have a happy and beautiful home. May each of us become a drop of water that nourishes human civilization.
Please join me in shouting: cherish life and save water!
Thank you!
Speech on Saving Water Resources Dear teachers and students,
Hello everyone!
I found that some children like to play with water, so that they waste some water.
Water is an indispensable part of human beings. People can go without food for three days, but they cannot go without water for three days. The water on the earth is very rich, * * * as much as145 billion cubic kilometers. But 97.5% of them are salt water, which cannot be directly used by human beings. The freshwater resources of the earth only account for 2.5% of the total water, but 87% of these freshwater resources are difficult to use. The water that human beings can really use accounts for about 0.26% of the total water of the earth. Even more frightening, it is predicted that by 20xx, 3 billion people in the world will face water shortage, and 40 countries and regions will be seriously short of water. The total water resources in China is 2.8 trillion cubic meters.
According to internationally recognized standards, the per capita water resources below 3000 cubic meters are mild water shortage; The per capita water resources below 2000 cubic meters are moderately short of water; The per capita water resource 1000 cubic meter is a serious water shortage; Water resources below 500 cubic meters per capita are extremely short of water. At present, there are 16 provinces, cities and districts in China, and the per capita water resources of 6 provinces (Ningxia, Hebei, Shandong, Henan, Shanxi and Jiangsu) are below 500 cubic meters. Visible how precious water is!
Let's save water and cherish what we need-water!
Speech on Saving Water Resources Dear teachers and students,
Hello everyone!
"When the last leaf falls, life is over, and I have to leave this world." This is a sentence in the last leaf, which reveals a fact invisibly: people can't live without nature, let alone water!
Some people say that water is inexhaustible. But I can definitely refute him: "That's not the case!" Although most of the earth's surface is water, 97. 55% of the water is seawater, which can neither be drunk nor used to water crops. The water available to human beings is less than 1% of the fresh water in the world! I don't know this data without reading it. Shocking. But even so, how do we humans do it?
"A ton of water is seventy cents, which is too cheap. What can be saved? " I always hear someone say this in my ear, and then scenes appear in my mind: in the bathrooms of hotels, canteens, schools and so on. Many faucets are left on and ticking away. Listen, it's like Mother Earth is crying!
Water is not just water, it is the origin of life, the embodiment of life and the source of life! Without water, flowers will not bloom, butterflies and bees will no longer dance for them, beautiful fireflies will not be seen, and frogs will not be heard. Any living thing will disappear and be destroyed. What a terrible, cold and lifeless world it is.
Water moistens the grass, washes the flowers with the green of hope, and embellishes the flowers with exquisite elegance ... Now, the water is slowly decreasing and moans in the torture of time. However, the actual actions of human beings will inevitably restore it to its previous mental state! Students, let's cherish and protect water resources from now on, so that the earth is no longer sad and sad. Saving water resources is everyone's responsibility!
Speech on saving water resources 7 Dear teachers and students,
Hello everyone!
Do you still remember the text we learned? It used to be the largest and most spectacular waterfall in the world-Sete Caidas Waterfall. She poured thousands of miles and stirred up thousands of lotus flowers. It is said that the loud noise of the waterfall is still audible 30 kilometers away. It has attracted countless people to watch it ... but now, if you want to visit it, you may be extremely disappointed. Today, Seti Caidas Falls has become withered.
Coincidentally, Huangguoshu Waterfall, which is recognized by us as the most spectacular waterfall in China, was originally the envy of all those who have experienced his style. But now, he is like a dying old man, and all the tourists who come here can only go on a whim and be disappointed. It is said that only when senior officials go to inspect, the manager opens the reservoir to release water, and then he is lucky enough to see its former style.
What a sad thing it is! What makes the source of our life gradually die out? Deforestation, pollution and uncontrolled waste ... Statistics show that every year, 654.38+0.2 billion people in the world suffer from various diseases due to drinking polluted water, 654.38+0.5 million children under 5 years old die from diseases caused by unclean water, and more than 5 million people die from diseases caused by water pollution, such as cholera, dysentery and malaria.
Water is a necessity in our life, but now most of it has been destroyed, so it is urgent to take good care of water resources. If we continue to waste blindly, our country and even the world may fall into a serious state of water shortage, and we will die of thirst because there is no water. You may say that our country has the Yellow River and the Yangtze River. How can you be afraid of running out of water?
In fact, they are already on alert. China is a country with drought and water shortage. China's total freshwater resources are 29 trillion cubic meters, accounting for only 6% of the global resources, ranking fourth in the world after Brazil, Russia and Canada. However, the average per capita is less than 2,200 cubic meters, accounting for only a quarter of the world average and a fifth of that of the United States. It is one of the countries with the least water resources per capita in the world. More than half of the more than 600 cities in China are short of water to varying degrees. In fact, 1 10 cities are seriously short of water, and the total water shortage in cities nationwide is 6 billion cubic meters.
Oil will lead to war. What kind of war will happen when water is as expensive as oil? If you don't want this cold and bloody war to happen from us, then start from us, cherish water resources and save water!
Maybe you will say, "saving water is the responsibility of the government. Even if I have the heart to do it, I have no ability." Actually, you are wrong. It's not just those vigorous events that are called salvation. There are many things we can do around us: turn off the faucet when we see it; Use a cup to receive water when brushing your teeth; The water for washing vegetables is used to water the flowers; Flushing water is used to flush the toilet; Tell your parents tips on saving water ... these are all things you can do to save water.
Students, don't think that our mother earth is still full of vitality and unlimited energy. In fact, she is getting old and losing some important resources. Save water resources, gather sand into a tower, as long as we join hands and work together, we will definitely make our mother earth radiant and show a healthier and younger face!
Speech on saving water resources Dear teachers and students:
Hello everyone!
Saving water resources is a truth that we all know. Water is the source of life and an indispensable substance in human life. Plants need water, and animals need water ... if there is no water in the world, will there be life in the world? We lead everyone to start from the usual bit by bit and reduce waste. Let me tell you a few things about our family cherishing water:
Once, my grandfather and I were watching TV with great interest. Grandma washes clothes at home, so I hurried over to help her wash clothes and reduce her burden, so I helped her wash clothes seriously. After a while, grandma finished washing clothes like hills.
My grandmother and I finished the clothes as bright as new. When my grandmother was about to pour water, I immediately said to her: Grandma, the water you use for washing clothes can be used to mop the floor and flush the toilet. Now, because humans don't know how to save water, many places can't drink water, even dirty water. We are really lucky where there is water to drink. Grandma said happily, "OK, that's a good idea. Grandma wants to learn from you to save water and reuse it. " The grandfather sitting next to him smiled and said, "Fan Yi has grown older, is sensible and knows how to save water." I also smiled happily after listening to it. It was the teacher who made me form the good habit of saving water!
Another time, when I was doing my homework at home, my mother brought back a bag of fruits, including bananas, apples, plums, mangoes and so on. My mother asked me if I wanted to eat fruit, and I said "yes". Mother turned on the tap when washing fruit. I went into the kitchen and said to my mother, "Mom, you can put a basin under the faucet to receive the water for washing fruit, and then you can water the flowers with the water for washing fruit." Mother thought what I said was reasonable, so she took the water in the basin as I said. In this way, the fruit is washed and the flowers are watered. Kill two birds with one stone.
Finally, I appeal to everyone: we should cherish water resources and save them. For a beautiful and happy tomorrow, don't let the last drop of water in the world be human tears, cherish every drop and save water resources.
Speech on Saving Water Resources Dear teachers and students,
Hello everyone!
I-a poor little water drop; We-the source of life!
Our mission on earth is to serve mankind wholeheartedly, but you humans always don't cherish us very much, as if you don't want us to stay too long. You only allow us to stay in the world for one second. You can easily turn the tap. At this moment, we are most worried, because thousands of unfortunate compatriots will disappear in an instant, and we can only cry and say goodbye reluctantly. ......
Faced with this wrong behavior, you humans often explain: we didn't mean it, and then we will guarantee to save water next time! However, they are not sincere! These mistakes are like Pandora's box, which is opened again and again, even ...
In fact, we really want to make some contributions to the world. The point is that you have to give us a chance. If you don't cherish us and end our lives conveniently, how can we serve mankind? Isn't there an old saying that if you don't respect others, others won't respect you!
Today, we suffered another misfortune. During the break, a boy went to the sink to wash his hands after going to the toilet. He turned the tap hard and turned it to the full range. After washing his hands hastily, he ran back to the classroom. Forgot to turn off the tap, only to see countless drops of water decisively end his life. I was angry and anxious, so I had to work hard with my companions behind me to pull back my compatriots in front. We tried our best, but to no avail. How does our little body escape the choice of fate? Fortunately, a teacher later found that the faucet was turned off in time, otherwise the consequences would be unimaginable!
Humans! We are innocent, don't hurt us! You humans can't live without water resources, what's more, water resources are non-renewable. So, please cherish us! Really don't want me to be the "last tear"!
Speech on saving water resources 10 Dear teachers and students,
Hello everyone!
Turn on the TV, turn to the news broadcast and see this inspiring news.
On TV, there is a dry land, the land is cracked and nothing grows. There is no water in the river, no water in the well, no water in people's pots and cups ... there is drought everywhere. This is Yunnan, where residents live without water, one or two glasses of water a day; Take a bath only once a month; What a hard life it is to pile up the dishes after dinner and rinse them with a little water when there are too many dishes. It hasn't rained here for a long time. How will the residents live without water?
Seeing this news, I really sympathize with those residents. You know, life without water is so miserable. Water is the source of life. We can't live without water. Nowadays, most parts of our country are suffering from drought. Fortunately, Guangzhou is fine, and we are not short of water. However, if we don't cherish water resources, Guangzhou will still encounter drought.
In the city, some water faucets and water pipes can be seen everywhere, and a steady stream of water flows out from there. Who wastes water so much that he doesn't turn off the tap? A few days ago, it was reported in the news that another water pipe burst in Guangzhou. Think about how many lives will be saved if these waters reach our west. This water may be nothing to us, but it is a life-saving medicine for the residents suffering from drought. How precious.
Therefore, from now on, we should cherish water resources and can't waste water any more. When you turn on the tap, please think of the people who are suffering and turn down the tap; When you see an unfinished faucet in the street, please think of the people who are suffering and turn it off actively; When you see someone washing their hands without turning off the tap, please think of the person who is suffering and go forward and say, "Please turn off the tap." If everyone could do it, then we wouldn't waste so much water and there wouldn't be so much drought. Cherish water resources and start from us!
