Water is the source of all life on earth. Although the total amount of water resources on the earth is10.8 trillion liters, there are not many water resources that can be directly utilized by human beings, so water conservation cannot be just a slogan. The following is an example of an 800-word water-saving composition I collected for you. I hope you like it.
Water-saving composition 800 words (1) Water, the basic substance on the earth, deserves our praise! She gave birth to the world and all sentient beings; It is she who provides energy for life and makes life survive; Or did she let life develop continuously and become more and more prosperous? Therefore, it is no exaggeration to say that "water is the source of life".
But is water inexhaustible? We can definitely answer: No, although 70.8% of the earth is covered with water, 97.55% of the water is seawater, which can neither be directly drunk nor irrigated. In the remaining 2% or 5% of fresh water, the water that humans can really use is less than 1% of the global fresh water. It is true that from the appearance of primitive life on earth to the present, water has been serving life, working hard and never stopping. But I don't know if you have ever thought that there is a limit to water tolerance, and now water resources are in short supply! There are two main reasons for this situation: first, the lack of nature itself; Second, man-made destruction. Of course, we can't blame God for being unfair to us and giving us a planet short of water. On the contrary, we should thank God for creating a beautiful home for us.
However, even in this emergency, we humans are still wasting and destroying water resources. In addition, many citizens in our city secretly dig wells to steal groundwater. What a shameful act! Excessive pumping of groundwater will not only destroy the crustal structure, but also cause a series of disasters such as land subsidence and water level decline in rivers, lakes and seas.
"Destroying the environment at will will ultimately harm human beings"-this is not the case, but the problem comes-due to the discharge of a large number of industrial wastewater, the water quality has been seriously polluted, and it only meets the Class III standard, so it can neither be drunk nor used for irrigation; In an island county like Nan 'ao, water use depends entirely on "God's arrangement"-the rainwater collection area of all Shantang reservoirs, including flood diversion projects, only accounts for 3 1%, and it is still difficult for industrial and agricultural production and people's living water. It can be seen that it is urgent to properly handle the pollution and destruction of water resources.
Therefore, I would like to make some suggestions. First, advocate "multiple uses of one water". As the name implies, it is to reuse used water. For example, rice-washing water can be used to water flowers, and the nutrients in rice-washing water are excellent fertilizers for flowers and plants, which really kills two birds with one stone; Second, increase publicity. For saving water and protecting water resources, the most important thing is the awareness of all citizens, strengthening education and publicity, starting from me and starting from every little thing around us.
Finally, I want to make a loud appeal: "protect water resources, cherish water resources, and don't let our tears become the last drop of water on the earth."
Water saving composition 800 words (Chapter II) Water is the source of all living things on the earth. People need water, plants need water, and animals need water. What if there is no water in the world? Animals will appear listless; Plants will wither; The last tear of mankind will be the last drop of water.
Water is a valuable resource. According to statistics, the fresh water on the earth only accounts for 2.7% of the total water, while the fresh water available for human use only accounts for 25% of all fresh water. Human activities not only consume a lot of resources, but also cause water pollution, leading to water crisis. The crisis of water resources is not only related to the sustainable development of mankind, but also to the survival of mankind. Students, nature has sounded the alarm for us!
In the face of these bleak data, isn't our heart touched at all? Yes, that's right! Each of us is still wantonly destroying it. Generally speaking, on the one hand, China's water supply is quite tight, and the water shortage situation is becoming increasingly severe; On the other hand, the utilization rate of water resources is low and the waste is amazing.
According to statistics, China's agricultural water consumption accounts for more than 60% of the total water consumption, but the effectively used water only accounts for about 1/3 of the total agricultural irrigation water consumption; The water consumption per 10,000 yuan of industrial output value is also twice that of developed countries. The extensive use of industrial wastewater, urban sewage, pesticides and fertilizers in agriculture has increased the pollution of water resources. Serious water pollution also reduces the available value of water resources and further aggravates the water shortage in China. About half of the country's production and domestic wastewater is discharged into rivers and lakes without treatment, which leads to the deterioration of water environment in most parts of the country and makes the already scarce water resources more tense.
Saving water and protecting water resources is one of the important ways to solve the problem of water shortage in China. In agriculture, it is necessary to change irrigation methods, abandon flood irrigation and gravity irrigation, and popularize sprinkler irrigation and drip irrigation technology; Change crop varieties and plant crops with drought tolerance and low water consumption; Reduce the use of pesticides and fertilizers. In industry, industrial water is reused and recycled; Reduce production water consumption and improve utilization efficiency; Water treatment, discharge up to standard. At home, water has many uses; Promote water-saving appliances; Use less detergents and cleaning agents.
The water-saving sign I see is made of water drops, human hands and the deformation of the earth. The green circle represents the earth, and the blank part holds up a drop of water like a hand. Hand is a variant of the Chinese phonetic alphabet J and S, which means saving water, indicating that saving water requires public participation, encouraging people to start from me and saving every drop of water; The hand is like a winding river, symbolizing that water drops converge into a river.
Let's act now, and don't let the last drop of water on the earth turn into our tears!
A long time ago, when dinosaurs became extinct, a brand-new term "human" was born, which always made people wonder whether there would be higher-level evolutionary creatures if humans became extinct for a long time.
The answer is yes. However, due to the wanton destruction and waste of water resources by human beings, I think even if that creature does appear, it can't adapt to this dense fog and exhausted water environment.
The earth is no longer what it used to be. She lost her old face and didn't have enough milk to feed us.
I always hear people say how clear the river was at that time, and now people are not so anxious. Saving water should be the most important point for people on earth, because the depletion of water resources has seriously affected the daily life of people all over the world. With the continuous expansion of the world population, water resources are inversely depleted. Take China as an example, China is one of the countries with the poorest per capita water resources in the world. 13. Although the total amount of fresh water is 2.8 trillion cubic meters, the per capita resources are only 2,200 cubic meters. It is only 1/4 of the world average, ranking 27 1 in the world. What an exciting and frightening number this is.
Seeing this, you will definitely ask, then how can we protect the only water resource? The whole world has taken appropriate measures. For example, Washington, USA has enacted a temporary law prohibiting people from watering their lawns for a certain period of time, and will be fined immediately upon discovery. In Japan, the only developed country in Asia, all governments, enterprises and public places have signs of "saving water", and public toilets even have that kind of infrared-sensing water-saving device. Of course, we should not only learn from countries that lack water, but also reflect on the practices of countries that do not lack water: in Germany, many German families will save the water for cooking noodles and reuse the water for washing clothes to mop the floor.
Please join me in defending the future of water resources! This is also defending the future of mankind, the future of all living things on this planet.
Water-saving composition 800 words (Chapter IV) Water is indispensable in life, the source of life, the lifeblood of agriculture and the blood of industry. Water also allows Mother Earth to give birth to our offspring. But human beings are ungrateful and waste water resources. According to the data, although China is rich in water resources, there is little available fresh water, and with the development of industry, water pollution has become a serious problem, and many industrial wastewater stinks. In addition, the phenomenon of wasting water is also very serious. A medium-sized city wastes the equivalent of a Dongting Lake every year!
On earth, where there is water, there is life. All life activities originate from water. Water in the human body accounts for about 65% of the body weight, of which brain water accounts for 75%, blood water accounts for 83%, muscle water accounts for 76%, and even hard bones contain 22%! Once the human body is short of water, the consequences are very serious. Lack of water 1%-2%, feeling thirsty; Lack of water 5%, dry mouth, wrinkled skin, unconsciousness, and even hallucinations; Water shortage 15% is often more than hunger. People can live for a long time without food. If there is no water, they can live for about 5 days at most. So water is very precious.
Now that people are rich, their living environment is good, and they feel that water charges are cheap, they all increase water consumption, resulting in increased waste of water resources. For example, most families now use toilets, which makes flushing very convenient. But the toilet needs 5 ~ 7 liters of clean fresh water every time it is flushed; Sometimes in order to pick up a pot of hot water, a lot of slightly cold water is released in vain; Also, people in the city are very busy now, and often forget to turn off the tap, wasting a lot of water. Don't underestimate the dripping water. A drop of water is negligible. But it has been dripping, and the number is very large. It is estimated that Didi can collect 3.6 kilograms of water in 1 hour; 1 month can collect 2.6 tons of water. This amount of water is enough for a person's life. It can be seen that there should be no waste at all. As for the continuous small water flow, it can collect 17 kg per hour and 12 tons per month; Roaring "running water" can collect 670 kilograms of water per hour and 482 tons of water per month.
Although human beings have wasted a lot of water resources, they have already felt the value of water and started to protect it. Let's put an end to wasting water resources and protect them together.
An 800-word composition on saving water (Chapter 5): "The grace of dripping water is rewarded with a spring". Let's put aside its inner meaning and only look at its surface meaning. I can't help thinking, "Do we still have so much water to spray?"
In recent years, people pay less and less attention to saving and protecting water resources. Take China as an example. In China, 1/3 water body is not suitable for fish survival, 1/4 water body is not suitable for irrigation, 90% of urban water bodies are seriously polluted, 50% of urban water sources do not meet drinking water standards, and 40% of water sources are no longer drinkable. Let's not talk about these national events, just say Jiusan Lake next to the school. The water there is as black as ink and as smelly as rotten eggs. There are no lively fish in it, only the dead lake. Look at the lake. There are rubbish everywhere: broken plastic bags, discarded food bags and some mops. I really feel sorry for the swimmers in Jiusan Lake, so I took a bath with smelly water!
We have to, no, save water because of the shortage of available water resources. This may be just a drop in the ocean, but if we save a drop of water in Wenzhou, Zhejiang, China and even the whole world, these waters will merge into rivers. Now, let me talk about my water-saving action:
First, I turn on the tap moderately.
Maybe some students usually turn on the tap the most when washing their hands. Do you think this is the way they wash their hands? In fact, this is just a psychological effect, which has nothing to do with the size of water. Like me, I usually twist the faucet a few times, about 80 degrees, and the water volume is moderate. If you don't wash and wipe carefully, your hands will still be as clean as ever, and you will save a lot of water. Kill two birds with one stone. Why not?
Second, I will flush the toilet with face wash water. '
After washing your face every time, the water will become turbid and lose its transparency. At this time, I will think, "It's a pity to spill it. It is better to keep it for flushing the toilet! " "Just use the quilt to lift the water and pour it into the water over and over again. Sometimes there is too little water left to lift the cup, so I soak the towel in the water and put it on the toilet to squeeze it hard. I didn't put the towel back until the last drop of water was so big.
I think we should treat those unknown waters that continue our lives with this mentality. She is thirsty, too, so we should cherish her more. Otherwise, loach is the last fish, and human tears are the last drop of water.
