On saving water resources 1 Water is the source of life, the blood of industry and the lifeblood of a city. For a long time, people generally believe that water is "inexhaustible". If you don't know how to cherish it, you will waste it.
When I learned that China's per capita water resources are abundant, the regional distribution is uneven, the year is unpredictable, the inter-annual difference is large, and the water pollution is more serious, which makes water resources even scarcer. Tap water is actually hard to come by. Only by cherishing water and firmly establishing the belief that "saving water is glorious and wasting water is shameful" can we pay attention to saving water at all times. Do you know that?/You know what? Do you know that?/You know what? A faucet leaks a drop of water every second, wasting 360 tons a year, and a leaky toilet drains 3 to 25 cubic meters a month. If toilets or showers are replaced with water-saving products, cities across the country are expected to save 4% water every month. 900 million tons.
Beijing is short of water, Tianjin is short of water, and Shanghai is listed as a water-deficient city by the state. Today, more than half of the more than 660 cities in China are short of water to varying degrees, among which11is seriously short of water. The total urban water shortage in China is 6 billion cubic meters.
The problem of water resources in China has once again sounded the alarm. The shortage of water resources is a common problem in the world today, and governments and researchers all over the world are doing their best to solve this problem. Our government has also made relevant efforts to this end. From now on, I will contribute to the water-saving work, starting with the details of life. When the washing machine washes a small amount of clothes, the water level is set too high, and the clothes float around in the high water, lacking friction with each other, but not clean and wasting water. Don't wash clothes too little. It is also a water-saving method to concentrate on washing after waiting too much.
You can wash your feet first, and then flush the toilet with face wash water. A vat for collecting waste water should be prepared at home, which can completely guarantee the amount of water needed for flushing the toilet. Taomi water can be used to wash dishes, remove oil and save water. Raising fish and watering flowers can promote the growth of flowers and trees. Don't turn on the faucet when washing vegetables. Wash them in a clean water tank first, and then rinse them with Koshimizu. The automatic dishwasher can only be used when it is full of dishes to be washed. If the dishwasher is not used for washing dishes, don't wash them directly with water. Tableware is best washed in a basin, not directly with a faucet. Saving water is everyone's responsibility. Only when everyone pays attention to saving water, water shortage can keep us away, life will be stable and harmonious and the environment will be beautiful and comfortable. However, the problem of water cannot be completely solved overnight. However, I believe that as long as everyone takes action and insists on saving water, the water problem will be solved perfectly one day.
Save water, since childhood, water is the source of life, please cherish every drop of water.
Water is an important natural resource for human survival and the source of life. Every life on earth needs water to grow. How great water is, it is selflessly dedicated to those who need its help! However, is water inexhaustible? Many cities in China are seriously short of water because people use a lot of water and waste water resources at will!
According to the data, the fresh water resources that can be directly used by human beings only account for 0.3% of the earth! The desert mercilessly devours many trees, villages and fields, seriously affecting human economic construction and threatening human survival! People all over the world pay attention to saving water and protecting water resources. I also want to contribute to the society, starting from myself and starting from my side.
Getting up every morning, washing your face and brushing your teeth are all things we have to do, and naturally we can't do without water. At this time, it is necessary to use clever methods to save water! When washing your face, in order to save water, you can wash your face by putting half of the water in the washbasin. After washing your face, water can't enter the sewer. We pour it into a bucket specially filled with this kind of water and use it next time we flush the toilet. When we brush our teeth, we usually use ordinary cups to change water three times. It only takes about 3 liters of water to brush your teeth intermittently, and it takes about 6 liters of water to drain water continuously for 30 seconds! A family of three, brushing your teeth twice a day, can save about 540 liters of water a month! It seems that as long as you use water-saving methods, a little brushing will make a great contribution to society! Tap is one of the ways we get water every day. It can bring us convenience in getting water. On the contrary, when it is "angry", it will vent clean water droplets and send them into the sewer one by one. Therefore, be sure to tighten the faucet after using up the water and check whether the faucet leaks at any time. Even a small drop of water every day, a month will waste immeasurable water! In hot summer, people always feel unbearable heat. We always take a cold bath before going to bed every night. Then, when you take a shower, you should control the amount of water in the shower head and wash it intermittently. If you keep cleaning for a long time, you will waste a lot of water ... These are the tips for saving water when washing clothes. So, before adults prepare a sumptuous dinner for us, what are the clever ways to save water? It turns out that the water after washing rice and the water for washing vegetables also have their own uses. They can be used to water flowers, clean chairs and mop the floor ... adults say that washing rice can make flowers grow better! After listening to my introduction, it seems that everyone knows that second-hand water has many wonderful uses! You can also try these coup, I believe everyone will become a glorious water-saving guardian!
Cherish water more and waste less. Let's save water together! I believe that with the joint efforts of 65.438+0.3 billion people in China, water resources will become more and more abundant, and the motherland will become more beautiful and rich!
Argument 3 for saving water resources If there is no water, we humans will die of thirst; If there were no water, there would be no lovely world like ours. If there is no water ... yes, we should cherish every drop of water and every tear of Mother Earth. Everyone knows that water is very important and the only indispensable thing in life, so why waste water like that? Why do people still want to play with water? Why can't they realize their mistakes? Why didn't you stop them when you saw their behavior? Countless "why" came to mind.
This afternoon, our class held a "water saving" activity. During the activity, the teacher showed us many photos. What shocked me most was that Premier Wen was squatting on a cracked land. According to the teacher's explanation, I know: it used to be a wetland for people to grow crops. Because it didn't rain, it was very dry here. Premier Wen stood a foot deep, and looked down at the land with his head buried very low ... Seeing this scene, I was deeply lost in thought and thought: God, the drought in Yunnan has fallen to this point, we.
When I got home, I accidentally opened a website when I was looking up information on the computer. In an obscure corner, I found this amazing news: China is a country with severe drought and water shortage. The total amount of fresh water resources is 2.8 trillion cubic meters, accounting for 6% of the global resources, ranking fourth in the world, second only to Brazil, Russia and Canada, but the per capita water resources are only 2,200 cubic meters, only 25% of the world average, and 20% of the United States, ranking 1 in the world. It is one of the poorest countries in the world with per capita water resources 13. I was shocked when I saw it: the water we drink every day is facing such a great threat, and maybe one day we will be short of water. No wonder teachers often tell us that the last drop of water on the earth is your tears when we use water. I didn't know the meaning until I saw the news.
After today's class meeting and online news, I know that saving water, although only a small matter, is also our modest effort to cherish every drop of water from now on. If everyone does this, 654.38+04 billion people will gather into a very powerful force, and then our earth home will be even better. Students, let's start by saving a drop of water!
Water is a familiar substance around us.
March 22nd is the 9th World Water Day, and March 22nd-28th is the 24th China Water Week.
It is said that when the earth was just formed in the universe (from soil gasification to virtual reality), volcanoes erupted everywhere, bringing the water inside the earth to the ground; The landing of extraterrestrial meteorites also brought a lot of water from other planets. After hundreds of millions of years of evolution, the earth has become a blue planet, with water covering more than 70%.
However, in this huge "reservoir", more than 97% of the water is occupied by the salt in the soil, which is salty and bitter seawater. Only 2% or 8% of the remaining water is drinkable, and most of it is confined in glaciers in the Antarctic and Arctic, so that only about 1% of fresh water resources exist in rivers, lakes and underground. I can't help but feel sad and surprised: the Yellow River has been cut off, Settsadas Waterfall has disappeared forever, Huangguoshu Waterfall has lost weight overnight, and the Gulf of Mexico is mixed with water and oil-how many drops of water on the earth can moisten our withered mouthparts? I think the mother river has raised all the children in the world; Liang Shanshui spans 800 miles in Fiona Fang; Seeing that there is no water available in thousands of cities today, it is feasible to walk on the north and south banks of the Yangtze River! Where can we see your face today when the waves are rolling and the rivers are surging? I saw a few remnants, tears like broken beads: "I didn't see the elegance of that year"!
Think about how many dull but painful scenes there are in real life: water is beating here, and dripping water is hard to find in the distance; But at the faucet, the waves are rough and no one makes it close; Here is a drop of water, but there is no disdain to enter the throat; Although I feel sad before looking at the dry well, I still let the clear water flow forever.
The era of inexhaustible water has long passed, and the era of cherishing, protecting and utilizing water resources has arrived. We should develop the habit of saving water from childhood: the water for washing vegetables and rice can be used to wash dishes and mop the floor, and the oil removal effect is very good; The water after washing clothes can be used to flush the toilet; The water from fish farming can be used to water flowers and effectively promote plant growth; Mixing cigarette butts and other things in unused dirty water can kill some pests; Face washing water can be used as foot washing water; Conditional home to install some water-saving appliances; You can also use special large barrels of sewage to flush the toilet; Don't try to flush the garbage with the toilet and waste water-water is the source of life. Of the eight planets in the solar system, only the earth has enough liquid water for life to multiply. If all this water is used up, how can we talk about the word "survival"
If we act now, the last drop of water on the earth will no longer be the tears of human regret.
Water is the source of life. Water is the most precious gift given by nature to human beings. Water drops, trickle, rolling waves, surging rivers, we can't live without water all our lives.
As for water, everyone thinks that it is inexhaustible. Because of this, in today's 2 1 century, water resources are quietly dying with environmental pollution. The shortage of water resources has also become a major crisis facing the world today. Only three-tenths of the water in the world is fresh water for human use, and these precious water resources are also being lost in our waste. It won't be long before mankind will perish, all the creatures in the world will be unlucky, and the earth we have been defending will eventually be destroyed in our hands and become a ruin. This will also be the result of human beings continuing to waste water. However, even so, I found a hateful phenomenon on campus. That day, I came out of the bathroom and found that the faucet there was broken. Drops of clear tap water flow out like a river. I tried my best to turn it off, but I couldn't get what I wanted. I immediately called a strong boy and asked him for help. But he casually said: "classmate, don't worry, this is tap water, which can't be used up." It doesn't matter. " After listening to his words, my heart couldn't help trembling: God, there is a lot of water, but sometimes it is used up. No matter how wide the sea is, there will be an end, and there will be times when it will dry up. For this classmate's words, I immediately defended: "Water is the most precious resource of human beings and the foundation for maintaining human life. We should cherish it. " But who knows, my words not only didn't wake him up, but brought him a cold shoulder. I can only turn off the tap with all my strength.
I learned a lot through this incident. It is precisely because of human's ignorant attitude towards water that some factories discharge waste water into the water day and night, which makes fish lose their homes, seriously threaten their lives and die constantly. But water, which ignorant people always think is not surprising, is the source of war. The Nile is the largest river in Africa, flowing through 65,438+00 countries. However, due to the influence of global warming, pollution and waste, its water flow has been decreasing in recent years, which makes many countries that take water from it suffer from "thirst". Nowadays, the dispute over water resources in Sudan, Egypt and other countries is intensifying, and the danger of "water war" is increasing day by day. Please save the gift of nature. Water is a beautiful paradise and a resource for human survival. Protect it, don't let it become human tears and regrets!
Water is the need of all things, cherishing water is people-oriented, human life needs water to protect, and water life needs people to protect. Let's start from ourselves, cherish water resources and protect the environment, and the world will be better!
Water is an important natural resource for human survival and the source of life. Every life on the earth needs water, and water is the same resource as life. However, human beings think that water resources are renewable, so they waste them at will. Africa and other continents are short of water to varying degrees, and some areas in China, such as Inner Mongolia and Xinjiang, have experienced land desertification. So, how can we effectively alleviate this phenomenon? I think we should start with me.
You can wash your hands with the water after washing vegetables, because there are green pigments in vegetables, and maybe you can beautify yourself! Now some families raise fish, and the water that raises fish can water the flowers, because there is fish excrement in the water that raises fish, and excrement is fertilizer, which is equivalent to fertilizing your flowers! We can store the used water in a bucket and use it when flushing the toilet. And this method is also beneficial, because it is free and clean to flush anywhere with barrels. In some families, the water for washing faces is directly dropped, and the water for washing feet is connected again. If you use 4 liters of water for washing your face and feet, wouldn't you save 4 liters of water by using the water for washing your face and feet again? Such people can save 1460 liters of water a year! In the north, people like to eat noodles, and most families will throw away the cooked soup, but I think it is better to stay, because as the saying goes, "the original soup is the original dish." Drinking this soup can help digest food, save water and wash the pot. You can kill two birds with one stone by using this soup to save your detergent!
In hot summer, people always feel unbearable heat. Every night before going to bed, we have to take a cold bath. When taking a shower, we can completely control the amount of water in the shower nozzle, and we must wash it intermittently. If you keep cleaning for a long time, you will waste a lot of water ... these are tips for saving water when we take a bath. So what are the clever ways for adults to save water before preparing a sumptuous lunch for us? It turns out that the water after rice washing can wash vegetables and effectively remove pesticides. Remember not to pour water after washing vegetables. You can use it to water flowers and wash toilets ... adults say that the water after washing rice can make flowers grow better. After listening to my story, you may know some ways to save water! You can try these coup, I believe everyone can become a glorious water-saving guardian!
Cherish water more and waste less. Let's save water together! I believe that as long as each of us tries to save every drop of water, we will certainly be able to alleviate our water shortage problem and not let our tears become the last drop of water on the earth!
As we all know, the water on the surface of the earth accounts for 70% of the earth, but the fresh water that can make life on the earth only accounts for 2% of the water resources. 5%, this water, is a necessity for our human survival. Do you think it should be wasted?
If you don't waste water, you must save it. So how can we save water? Try the following methods: Taomi water can be used to water flowers, and the faucet should not be turned on all the time; The waste water used at home can be used to flush toilets, etc ... You may ask, "Is it necessary to save so much? It's too stingy to wash rice and water flowers! " Haha, I don't understand. Taomi water is nutritious, and you can also wash your face!
We should not only save water resources, but also make rational use of them. Now, many hydropower stations have been built. They use water to generate electricity, which is both environmentally friendly and beneficial. It's killing two birds with one stone. People also use reservoir water to irrigate farmland, which plays a role in agriculture.
Despite the above-mentioned water-saving measures, due to the rapid growth of population, our water resources are still lacking. In fact, protecting water is not easy. On the one hand, we should plant various trees and crops to prevent soil erosion; On the other hand, let everyone know that polluting water resources is a real suicide. Only by not excessively polluting water sources, cutting down trees and reclaiming wasteland can we really and effectively achieve the purpose of saving water. Therefore, no matter what measures the government takes, the key lies with each of us, and our lives are in our own hands. Everyone must think about this problem.
You know Africa, where there is a serious water shortage. Every day, a family only weighs five pounds of water, including cooking, feeding animals, bathing and washing faces ... After hearing this "notice" of emergency water shortage, act quickly! Every year on Arbor Day, I plant a piece of "green love" in the wild with saplings, shovels and buckets. I believe that as long as people all over the world plant a tree, soil erosion will be greatly reduced every year.
Water is the material basis on which life on earth depends, and water resources are the primary condition to maintain the sustainable development of the earth's ecological environment. Therefore, protecting water resources is the greatest and most sacred duty of mankind. Let's protect every drop of water from now on!
Water is the source of life, animals and plants can't live without water, and humans can't live without water. Once there is no water, we cannot live. However, potable fresh water resources are decreasing day by day. One of the reasons is the growth of the world population. Another more important reason is that many water resources have been seriously polluted. Therefore, in order to have sufficient water resources, we should not only protect water resources, but also save water.
How important water is to us! If everyone pays attention to saving water, I wonder how many people will benefit from it; On the contrary, if everyone wastes water resources carelessly, many people may suffer from drinking water difficulties! For example, some water pipes in public places leak, we can find someone to repair them, but if they are not repaired in time, it will be a waste of our drinking water. However, spilled water will never come back, which is tantamount to wasting water resources. How wrong this is!
If we don't save water, we are accelerating the pace of death.
Some people have developed a bad habit, that is, they like to throw garbage into rivers, lakes or other inappropriate places at will for convenience. Imagine that if everyone throws garbage into rivers and lakes, a lot of water resources will be polluted; If everyone litters at will, when it rains, the rain will wash the garbage into rivers and lakes, thus polluting the water resources on which we depend. If a lot of water resources are polluted, how can we survive? I think this bad habit is a temporary convenience and a lifelong injury, and it must be carved from the roots!
How should we save water? It's actually quite simple. Develop good water-saving habits in daily life, and you will save a lot of water inadvertently. People have created many effective methods in their daily life. I'll teach you a few tricks, such as washing water and shower water for flushing toilets, fish water for watering flowers, rice water for washing dishes, residual tea for cleaning furniture, water-saving faucet and vegetables. ...
Earth! This thing is a miracle of the universe, so cherish it! Saving water means protecting the earth from dryness. More importantly, saving water resources means saving our next generation!
If we humans resolutely waste water again, then our children and grandchildren will soon be short of water? So, don't our future generations just ...
Humans! The prodigal son never changes money! Let's go to * * to save our important resources! Let's make tomorrow better in the near future! Become richer and stronger!
Water is the source of life, the 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! In other words, water is the life of 2 billion people. In the world, 50 million children die every year because of drinking unclean water! How shocking this figure is! The water crisis has sounded the alarm for mankind! Saving water and protecting water resources are the top priority now!
How important water is to us! If everyone pays attention to saving water, I wonder how many people will benefit from it; On the contrary, if everyone wastes water resources carelessly, many people may suffer from drinking water difficulties! For example, some water pipes in public places leak, we can find someone to repair them, but if they are not repaired in time, it will be a waste of our drinking water. However, spilled water will never come back, which is tantamount to wasting water resources. How wrong this is!
Some factories do not pay attention to the protection of water resources, and discharge industrial wastewater into rivers and lakes, causing pollution in many rivers and lakes. However, such a result has to be taken seriously. Fish and shrimp will die if they drink such water; If humans bathe with such water, they will get sick; If humans drink such water, it will be harmful to their health. Water ring devours the health of human beings and animals! Imagine that even if the employees in the factory earn a lot of money, the water is polluted and people have no clean water to drink. So how do they survive? What's the use of asking for such money at that time? How bad it is for others!
Some people have developed a bad habit, that is, they like to throw garbage into rivers, lakes or other inappropriate places at will for convenience. Imagine that if everyone throws garbage into rivers and lakes, a lot of water resources will be polluted; If everyone litters at will, when it rains, the rain will wash the garbage into rivers and lakes, thus polluting the water resources on which we depend. If a lot of water resources are polluted, how can we survive? I think this bad habit is a temporary convenience and a lifelong injury, and it must be carved from the roots!
Now, because many aspects are polluting water resources, and the pollution is getting more and more serious, human beings can drink less and less water. However, without water, human beings can't survive. This means that we should take active actions to save and protect water resources now. In order to save and protect water resources, I think everyone should put an end to the bad habit of littering casually and throw garbage into the trash can; The uncles and aunts of the factory must resolutely prevent industrial wastewater from flowing into rivers and lakes, and must be treated harmlessly before being discharged; If the water pipe at home leaks, find someone to repair it immediately; To form a good habit of saving water, don't waste water resources casually (such as playing with water guns, washing vegetables and clothes can be used to flush toilets, etc.). ).
Let's join hands to save water and protect water resources! I believe that through the efforts of all of us, we will be able to do it!
