72% of the total area of the earth is water, and the water we can use only accounts for 0.75% of all water resources. Nearly 70% of the water is frozen in the north and south poles, and the rest we can collect is even less. The total amount of fresh water in only nine countries in the world has reached 60% of the global total!
For us, and for the whole nature, let's act together and walk into the ranks of water saving! At ordinary times, our bath water and washing water can be collected to flush toilets and water flowers; Turn off the tap when not in use; Try not to play with water; I turned off the tap when I saw it dripping. ...
We should not only save, but also protect water resources.
Like the river behind my house. It used to be covered with large pieces of moss. The river was as black as ink, and it smelled bad in summer. A few months ago, a cleaning ship, a huge manipulator, reached into the water and grabbed a large piece of black mud. I was shocked. It turned out to be so dirty. After cleaning, the river turned green, the breeze blew, the blue waves rippled, and the small fish and shrimps frolicked underwater, very happy. But it didn't take long to think that the neighbors upstairs were still littering the river. Do they still want to make the river smelly and dirty? Please be kind to the uncles and aunts upstairs. Let's protect this clear river together.
If China/KLOC-0.3 billion people save one drop of water per person, there will be about 6,500 liters of water. Save a bottle of water, a bucket of water or even a can of water? Come on, let's save and protect water resources together, starting from individuals and starting from small things around us, and making the earth more beautiful!
I came across an article on protecting water resources during my holiday 2. The title of this book is "Will there be enough water?" . Yes, there isn't enough water, you know? It is estimated that by 20xx. Three billion people in the world will face water shortage. 40 countries and regions are seriously short of water. Water is the source of our life, and water is the root of life. Without water, we humans can't survive.
Water is essential for us humans, animals and plants. Without water, the earth will become a place without animals, plants, people, trees and air, so we humans must protect water. I saw in the book "100,000 Why" that "the water consumption of human beings is increasing sharply". It said: With the rapid growth of population and the development of urbanization, people's water consumption will also surge. Due to the accelerated development of industrialization, the amount of wastewater discharged by industries and cities all over the world has reached more than 500 billion cubic meters per year, which has reached 20xx years. 300 billion cubic meters, half of the world's groundwater resources are being polluted. According to the survey, about 1500 children under 5 years old die every year because of drinking polluted water. I feel terrible after reading it, so I think it is very important to protect water resources. How to protect water resources? I think we should always remind everyone around us to save water, not to waste every drop of water, not to cut down trees indiscriminately, not to use disposable things, not to pollute nature, and to protect the surrounding environment. Only in this way can we have more water to use on our earth and people can live better on the earth!
Children, saving water resources and improving water environment are very worthwhile and meaningful things. I believe that children's actions will influence and drive more people to participate in water-saving activities. I hope the children will be caring people who save water, leaders of civilized water use, and fully demonstrate the style of the times in saving and protecting water resources.
Kid! Let's take action immediately and actively join the ranks of water conservation!
Protecting water resources 3 Water is the source of life. We all know that the earth has life because it has water. Science has proved that people can live for a week without food, but they can't live without water. Seedlings, flowers and trees will wither without water, and animals will perish without water. Because of lack of water, cars can't drive on the highway. Sometimes a drop of water can decide a person's life and death. Therefore, whether it is domestic water, production water or farmland irrigation water, it is closely related to our lives.
"Water is the source of life, please save water." Everyone knows this sentence, but who can really do it? Whenever the teacher asks, "How should we cherish water resources?" Students always answer: "Turn off the tap …" But it's easier said than done! It is not enough to say it, but to prove it with your own practical actions. Below, I will discuss several issues with you.
First, is the water on the earth infinite or limited? Many voices came: "Limited, limited." It seems that many people think that water is inexhaustible. Actually, this is not right. Water is not like solar energy. It is limited.
Second, what percentage of the earth is water? Someone shouted: "water accounts for more than 70%, and land accounts for more than 20%." At this time, some people may think that I worry too much, but it is not. Think about it. How much water can you drink if you go out into the ocean and sewage? Even if we are not short of water now, what will our children and grandchildren do?
So through the above two questions, I believe everyone is self-evident. In the past, because people didn't cherish and destroy water resources, we could use less and less water. Students, as a good student, can we watch people waste water resources wantonly? And you don't care No, we should stop them and advocate human saving water.
Of course, it's no use talking. It is our duty to save water. Let's save water and protect water resources, and give us a beautiful living environment with green trees, birds and flowers, clear rivers and happy fish!
Protect water resources. Saving water is everyone's responsibility. How many people in today's society can do this? They all think that water is inexhaustible, but they are wrong.
When people turn on the tap, clean and sweet water will flow out. However, this tap water is not really "spontaneous", but is taken from rivers and reservoirs hundreds of meters deep and dozens of kilometers away, and it is difficult to be disinfected. Some countries can't even drink water and quench their thirst by rain, but it doesn't rain often.
When it rains, people take out pots to receive water. You know, rain is also very unsanitary, but you must drink it in order to survive. If you give it to me, you may not be able to drink it. There is another story: some people who travel in the desert are so excited that they can't wait to run in and wash their faces when they see a village in front of them. They came to a house and asked them for water to drink. They thought about it and agreed. When they saw the tourists splashing water on their faces, they immediately rushed to dig out the sand soaked in the water and cover it next to the plants. How precious water is!
According to statistics, families can save about 70% water by getting rid of bad water habits. Water in human body accounts for about 60% of body weight. But how to save water? First, the water after washing your face can be used to wash your feet and then flush the toilet. 2. Rice washing water or noodle cooking water can be used to wash dishes. The water from fish farming is used to water the flowers. ...
Therefore, water is the source of life, so we should save every drop of water around us. If human beings do not cherish water resources, the last drop of water on the earth will be human tears!
Protect water resources 5 water, a necessity in life; Water, the most common and precious thing; Water, one of our greatest wealth. I often ask myself, "Are we still here without water?" -inscription
People who love life must love water. Because they know that water is not the whole of life, but an indispensable part of life. It is water that gives life to nature, makes life full of vitality and makes the Chinese nation flourish. If there is no water, it will naturally wither; If there is no water, the world will be destroyed; Without water, everything would be gone. Therefore, we can't leave the water and the support of life!
However, in real life, how many people understand this truth? They just think that water is the most common thing, who will cherish it? No, few people cherish water like me. Now, how many people worship money? In their eyes and hearts, I'm afraid there is only money, right? How can such a person with a copper smell know the coolness and sweetness of water? How do you know the importance of water? In their minds, only money is the most important thing, right?
People often say that I was the purest when I was young, and my eyes were watery. This shows that the water is pure, and she is clear and pure. She is cool and sweet. She is the most beautiful thing in the world!
Really, I like water. Because of her purity, how many things in this world are pure? I'm afraid not much?
Don't pollute water any more, they can't stand it, they are pure, but they are also fragile; Don't hurt them any more, they are already scarred ... It really hurts to see those white, unrecognizable waters break my heart ... Wake up, how many things in this world have not been destroyed by us. ...
Protecting water resources 6. Water in life is inseparable from us, and it cannot be separated from water at any time. It can maintain human life, shipping, breeding and support agricultural production. It can also be used in daily life: washing clothes, cooking and feeding livestock. Water is the source of life for all things in the world.
Water accounts for 65% in human body, 90% in blood and about 70% in muscle. Even bones have more than 20% water content, and the eyeball has the most water content in human body. If there is no water, human beings can live for up to 3 days, and people have to drink at least 8 glasses of water every day to keep our health. It seems that water is so important!
On the earth, although there is a huge amount of water, most of it is salty and bitter seawater, and some of it is icebergs, glaciers and groundwater, which human beings cannot drink. The remaining fresh water is water that people can drink. It can be seen that our available fresh water resources are very limited.
The fresh water on the earth is very limited, but some students still waste it. Some students always like to play in the bathroom. They will throw water at each other. Maybe they are happy, but I am sad. Some students said to the dripping faucet, "Isn't it just a small drop of water?" But have you ever thought that there is only one earth, and if we don't love him, who will love him? We must start with individuals.
For example, the water after washing vegetables can be used to water flowers and vegetables; The water after wiping the floor can be used to flush the toilet. Isn't this more water-saving?
Please look at the fact that there is less and less fresh water on the earth now. Rivers and streams have been destroyed by human beings. They turn clear and sweet water into bitter water and poisonous water, making it impossible for fish to survive, for humans and animals to drink, and for plants to absorb.
In this way, the last drop of water will be the last tear of mankind.
Protect water resources. Has it changed from water pollution in the past to air pollution today? The safety on the tip of the tongue has become an unsafe fact. Why are there all kinds of environmental pollution problems today? There is no explanation, it is human's fault! ! !
Can't be ignored! I don't want life on this earth to last only 100 years.
Why should the wastewater discharged from industries and factories be directly discharged into various rivers, lakes and seas? Do you know that there is a lot of water on the earth? It is estimated that the total volume of water is about 65.438+0.38 billion cubic kilometers. If these layers are distributed on the earth's surface, it is equivalent to that the whole earth's surface is covered with a layer of water with an average depth of 2650 meters. Unfortunately, 98% of this water is salt water, which is mainly distributed in the ocean. Fresh water accounts for only 2% of the total water volume of the earth, about 30 million cubic kilometers, and this 2% fresh water cannot be fully utilized by human beings, because 88% of it is frozen in polar ice sheets and glaciers, and the remaining 12%, that is, rivers, lakes and exploitable shallow groundwater, can be utilized by human beings, most of which are groundwater, and the water of rivers and lakes can be directly utilized without exploitation. The water on the earth is always changing. Water in the ocean and land evaporates into the atmosphere, and then rain or snow falls back to the earth, nourishing everything, replenishing rivers and lakes or injecting into the sea. Water will also seep into the ground and flow into the aquifer. The extremely deep groundwater can neither be replenished nor exploited, which is called primary water, so it can't be regenerated. It is precisely because of this fluidity of water resources that land floods or droughts occur, resulting in uneven distribution of water resources. About 65% of the world's water resources are concentrated in 10 countries every year, and 80 countries (including 9 countries in the Middle and Near East) with a population of 40% of the world's total population are seriously short of water! ! Cherishing water resources is what every qualified citizen should do! Warn all unscrupulous factories not to drain water indiscriminately!
It is urgent to protect water resources, starting from small things!
Protecting water resources 8 70% of the earth's surface is covered with water, but fresh water resources only account for 2% of all water resources. 5%, nearly 70% of fresh water is fixed in the ice layers of Antarctica and Greenland, and the rest is mostly soil moisture or deep groundwater, which cannot be used by human beings. There is less than 1% fresh water or about 0. 007% of water can be directly used by human beings, while the per capita fresh water resources in China only account for a quarter of the world's per capita fresh water resources.
Even though the water resources we have are so scarce and precious, we don't take it seriously. Global water pollution, excessive consumption and improper management of water resources have led to a sharp decline in the quantity and quality of available water resources. Now, 6000 people in the world die every day because they don't have access to water or clean water. If this trend cannot be effectively controlled, after 20 years, two-thirds of the global population will be in danger of running out of water.
In order to better protect water resources, I want to give you some suggestions:
1, start from yourself and don't destroy water resources with others. We should also start from the family, let them know the harm of destroying water resources, and let them not destroy water resources. Let others protect water resources like you.
2. Save water at home. Don't pour water after washing vegetables. It can also be used to water flowers. Parents should also save water at work. Don't think that workers' water can be wasted. This is an incorrect performance of saving water. It is also irresponsible.
If you see someone deliberately destroying the water source, you should bravely persuade him and explain that destroying the water source will bring us great danger. And let him protect water resources in the future. Those who do not listen to dissuasion and the circumstances are serious should report directly to the relevant departments and be punished according to law.
4. At school, we should be role models for our classmates, and we should also be role models for our classmates. Let students also have a sense of responsibility to protect water resources. Like mopping the floor, students waste a lot of water when washing mops. If you waste it like this, you will waste a lot of water! There should be two pools where mops are washed, one for washing dirty things and the other for cleaning. When students mop the floor, there are many dirty things on the floor. First, go to the pool where the dirty things are washed. Rinse in a clean place. This saves a lot of water, not only saves water, but also cleans the mop. It's killing two birds with one stone!
Friends, let me take action and make efforts to protect water resources and nature! Let's form the consciousness and habit of cherishing, saving and protecting water resources from the beginning, not only for human beings, but also for everyone's tomorrow! Don't let the last drop of water become our tears.
Protecting water resources 9 In the boundless desert, there will always be strong winds, which will blow the earth scarred; In a muddy lake, there will always be poor shrimp and fish who can't adapt to the environment and die; Every time I walk into the street, there is always a stench covering my nose and mouth; Whenever a car passes by, there will always be a dust. Our mother, the earth, is being destroyed. It is her children who are destroying her, making her tired and her eyes shining with tears. It seems that he is moaning.
This is all man-made: cutting down trees, building chemical plants and discharging harmful liquids at will. "The annual emissions of gases that pose a greater threat to mankind in the world exceed 600 million tons ...; It is estimated that by the middle of the next century, one third of the earth's surface will be in danger of desertification, and 6 square kilometers of land will be desertification every year, threatening more than 60 countries ... "Let's open our eyes and look at these terrible figures and information! The earth is beautiful, but I don't want her to be down and out from now on!
To this end, we should protect the environment! I advocate students to improve their awareness of environmental protection, and also suggest that uncles and aunts join our team to contribute to environmental protection and benefit future generations. Because: protecting the environment is urgent!
"The real test of our contribution to the environment is not words, but actions." Although I am only doing some small things now, it is ok to start from myself, from small things, and from now on! Take a nap on the vast grassland; Grow up in the beautiful sky and bathe in the clear river. Although this is only a dream, I think it will come true one day, so we should do our best to protect the environment. To realize this dream.
The earth is the planet where we live. If you are dirty, how can you live well? If we destroy it, where else can we go
Zeng Xianfeng
Protect water resources 10 Water is our life resource. In many cases, we can't live without water. People can go without food for several days, but they can't go without water for several days, so water is the foundation of life. It was water that saved our lives in difficult times, but people didn't know how to save them.
At present, there are more than 2 billion people on the earth without water. How amazing this figure is! Yes, but some people are still wasting water resources. For example, they leave the tap on when washing their hands and throw rubbish into the river at will. ...
In front of our school, there is a river called Liangyunhe. In the past, the river was crystal clear. There are many beautiful willow sisters and all kinds of flowers and plants on both sides of the river. Sometimes there are one or two boats in the river for people to enjoy, and the small fish in the river are also playing freely. In summer, the river "spouted" and became a beautiful movement. People are proud of it. However, today's grain river is different. The river has gradually turned from clear to black, and it will smell a pungent smell from a distance. The river is full of rubbish and rotten leaves, which makes people tired of it gradually.
It's all people's fault, which turned the beautiful grain river into today's stinking grain river, but no one stood up to protect it. In order to protect water resources, we should start from an early age and call on all mankind to protect the source of life with gratitude. Now, countless oceans, lakes and rivers are asking us for help: "help us!" " Help us! This is for yourselves, too ...
Finally, I sincerely warn people: protect water resources! Don't let the last drop of water become people's tears, and don't let the last one become people's confession!
Protect water resources 1 1 Small fish shuttle between lotus leaves like silver needles, and ducklings swim "fluttering" ... This is a story closely related to water that my mother told me when I was a child.
But now the water has become like this: there are some beverage bottles, white lunch boxes and plastic bags floating on the water. Some unscrupulous businessmen discharge a lot of sewage for their own benefit, which makes the water surface dirty and smelly, and some management departments do not pay attention to the importance of protecting ecological water. All the fish died tragically one after another, floating on the water with their stomachs turned upside down, which was very disgusting. The consequences of all this are caused by human beings themselves, and they are for their own interests.
What should we do in the face of this severe water resources situation: We should have the consciousness of cherishing water resources. For a long time, people generally believe that water is "inexhaustible", and it is not cherished, and some even wasted. We should know that China's per capita water resources are not rich, and the regional distribution is uneven, with great inter-annual differences and unpredictable changes during the year. In addition, some water is polluted, which makes water resources scarce and tap water more difficult to get. Cherishing water is the basis of saving water. Only when we realize that "saving water is glorious and wasting water is shameful" can we pay attention to saving water all the time. On the other hand, everyone should pay attention to environmental protection and make friends with water. All water-related damages should not happen again. We should not pollute and waste water, but protect and save it. Only in this way can our world become better.
Water is one of the indispensable conditions for human survival. Without water, there would be no life, which shows the importance of ecological water.
Protect water resources 12 If all rivers dry up, it means that all living things will perish. What a terrible thing!
If all the small rivers dry up, there will be no water in the big rivers; There is no water in rivers, and there will be no water in the sea one day; There is no water in the sea, so there is no water in the world. If there is no water, animals can't drink sweet water, and we can't hear the beautiful songs of birds and the cheerful calls of lions ... Without animals on earth, we can't see the thriving scene of nature.
If all the rivers dry up, the life of plants will be threatened, or even never survive. Without water, there would be no flowers, no grass, no trees ... without color, there would be no vitality naturally.
If all the rivers dry up, there will be no water. Without water, not only the lives of animals and plants are threatened, but also the lives of people. Without water, people can't eat fish, shrimp and other animals living in water, plants growing on the ground, livestock raised by people and so on. , so people can't get enough nutrition; Without adequate nutrition, people will get sick and even die. Water is really important to us human beings. Water accounts for four fifths of our body. Without water, the circulation of many physiological functions such as transportation, regulation and digestion in the human body cannot be carried out normally.
If all the rivers dry up, there will be no water. Without water, all living things on the earth will be threatened. I hope this will never happen. Let's protect water resources and live in a world with water forever. Let's cherish a beautiful and peaceful "green home", and don't let our "green home" have only the last drop of bitter water _ our tears!
Protecting water resources 13 water is an irreplaceable resource for human survival and development, and it is the foundation of sustainable economic and social development. Every time I step out of the house, I feel stinking. The problem lies in the ditch in front of the door. From the day I have a memory, it is so clear that I can even go swimming. However, due to the economic development in recent years, industrial wastewater, garbage and domestic dirty water are continuously discharged into the ditch, which leads to the small ditch becoming turbid and yellow-brown, and the shaking gravel at the bottom of the ditch is no longer visible.
Is it only when we hold up withered skin with trembling hands in the endless desert that we finally realize the preciousness of water? Facing the continuous waste of water resources, what should we do? When it rains, we can use the "free water" given by God, or we can design a collector to recycle the collected water for drinking! This not only makes the water fee cheaper, but also saves water resources. I also have a "coup" to save water resources! Now that the economy is improving, every household is equipped with air conditioning. Have you ever thought that air conditioning water can also be saved? Every night, put a big bucket under the air conditioner. Looking into the bucket after getting up, you will be surprised to find that the water in the air conditioner is actually full of vats, which is estimated to be several kilograms! Can be used to flush the toilet!
Can't this also save water? The vegetable washing water we usually use can be left to water the flowers and flush the toilet; The water discharged from the washing machine for the second and third time can also be left to wash the floor; And mopping water. Don't underestimate it. It can also flush the toilet! In order to protect water resources, I would also like to make the following suggestions:
1, make full use of water resources without wasting.
2. Do not discharge waste water and garbage into rivers, lakes, rivers and ditches.
Don't wash dirty clothes by the ditch.
4. Promote "protecting water resources" to people around you.
Water is the cradle of life, and it is what any living thing depends on. People, don't just ask for it, but don't know how to cherish it, or even pollute and destroy it. There is a blue sky above us and a piece of land under our feet. Let's protect water resources together!
Protect water resources 14 water is the source of life, the foundation of life, and human health cannot be separated from water. 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 in the world die from drinking unclean water! How shocking this figure is! The water crisis has sounded the alarm for mankind! Although China is rich in water resources, it is unevenly distributed, with less water in the east, more in the south and less in the north, and many places lacking water. Where there is no shortage of water, people waste and pollute water too seriously. Last year, the school organized students to visit Maozhou River. When I came to Maozhou River, the riverbank was full of ant nests, and the river was full of plastic bags, old sofas, cigarette cases and other wastes. This river has been polluted by human beings for a long time, giving off an unpleasant smell, which makes people feel very uncomfortable. Teacher Zhang told us that Maozhou River is the largest river in Bao 'an District, which originates in Yang Tai, flows through Shiyan, Gong Ming, Songgang and Shajing from east to west, and flows into the Pearl River Estuary. Maozhou River has some problems, such as low flood control capacity, serious soil erosion and serious river pollution. I thought: If people didn't throw rubbish into the Maozhou River, how could it be like this? I remember another time, my mother happily bought a fish head from the street and used it to make fish head soup at noon. Unexpectedly, the cooked fish head soup is not fresh and sweet at all, but has a strong smell of kerosene. My mother quickly told me not to eat it, saying that it was polluted fish and it would be poisoned if eaten. My mother also told me that some factories did not pay attention to protecting water resources and discharged industrial wastewater into rivers and lakes, which caused serious pollution of water resources. Fish and shrimp live in such water and will slowly die of poisoning; People who drink such water will get sick and seriously affect their health. After listening to it, I feel really terrible! Why do humans only know how to make money and not how to protect water resources? At this rate, it will be difficult for us to drink clean water. So, how do humans survive? I really want to shout out: human beings! Don't make the river ugly, don't let the fish be poisoned, and protect the water! Protect the source of our life!

Protecting water resources15165438+10/8, the sudden cold wind did not stop our enthusiasm. Accompanied by my parents, my friends and I participated in the activity of "Walking into the Water Source" organized by Wuhu Ecological Center.
We came to the Yangtze River water intake of Limin Road. We introduced ourselves to each other and then began to play games. The host divided us into four groups and sent some pictures to each group. Let's arrange the pictures according to the purification order of tap water. The last group of students got it right. The correct sequence is: water intake, coagulation, sedimentation, filtration, disinfection, and household entry. Through this game, we soon understood that the water from the original water source has to go through six processes before it can become the tap water we use every day! Knowing this, how can we not save water and protect water resources?
Knowing the order of tap water entering the house, we came to the Yangtze River to pick up garbage. A closer look shows that there is a lot of garbage on the riverside, including snack bags, beverage bottles and plastic bags. Despite the cold wind, everyone picked up a lot of rubbish. When I was picking up garbage, I couldn't help blaming the litterer again and again. This is very wrong. If the high tide of the river washed up on the shore, wouldn't it bring garbage into the river? How unsanitary that would be!
After picking up the garbage, the staff of the ecological center began to take us to measure the water quality of the river. Water is generally divided into five categories, one is the best and the other is the worst. We scooped up some river water with cups and compared it with the color chart to determine what kind of water our source belongs to. Fortunately, the water quality of the water intake of Limin Road probably belongs to the second-class water, which is still relatively good.
This activity made me deeply realize the importance of protecting water resources. The Yangtze River is our mother river, and people's domestic water comes from it. Let's protect our water source, don't throw rubbish on the shore, and don't throw rubbish into the water. Water is the source of our life. Protecting water means protecting ourselves.
