An impromptu speech on saving water (120 words)

Student: You must have seen such a public service advertisement: there is a faucet on the TV screen, which is dripping with difficulty. The dripping speed became slower and slower, and finally the water was used up. Then a pair of eyes appeared on the picture, and a tear flowed out from it. Followed by this sentence: "If human beings don't cherish water, then the last drop of water we can see will be our own tears."

Water is the source of life. If there were no water on the earth, Mother Earth would not give birth to our descendants. Because the earliest primitive life was first bred in the ocean and gradually extended to the land. Therefore, water is the cradle of life. The survival and development of human beings are also inseparable from water. Because we have to drink water every day, food growth can not be separated from water, and industrial production can not be separated from water. Water is also the "air conditioner" of nature. How happy it would be to have a rain in the hot summer when people feel unbearable heat! Walking by the sea, the sea breeze blows gently, sweeping away the hot and irritable mood; When the cold winter comes, the seawater continuously transfers the stored heat to the surrounding land ... all these are the functions of water.

Is water really not worth it? Is it really unimportant to save water? 93% of the water in the world is salty and can't be drunk. Fresh water accounts for only 7%, and drinking water accounts for only 0.8%. The world's 5 billion people depend on drinking this 0.8% fresh water. Look, how precious water is! Although China is rich in water resources, there are few available fresh water resources, and with the development of industry, water pollution has become a serious problem, and many industrial wastewater stinks. What a terrible thing!

March 22nd is World Water Day. Every year on this day, all countries in the world will publicize that everyone should cherish water resources and protect the water of life. In fact, it is not only this day, but every day in our life should cherish every drop of water and cherish the water of life with practical actions! Water exists in the sky, underground, rivers and lakes. 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.

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, 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.

Then how do we get the tap water we use every day? It is the uncle who works in the waterworks who introduces river water or groundwater into the factory, puts the water into the sedimentation tank, adds drugs for disinfection and sterilization, removes harmful substances and impurities, and buries many pipelines underground. These pipes are tied up one by one, which is the result of the hard work of many waterworks workers and uncles day and night. When we turn on the tap, we should think that the bread in the water contains the hard work of many workers' uncles!

Students, do you know the meaning of saving water? Please look at an account: one ton of water can supply about 150 kg of steel, generate electricity 1000 kg per hour, produce 500 kg of chemical fertilizer, weave 220 meters of cloth and grind 34 bags of flour. "Dripping water becomes a river", if everyone saves water, every little makes a mickle, they can play a greater role!

Students, we are small masters of the country, and we should develop good ideas and habits of saving water from an early age. Whether at school or outside school, we should pay attention to saving water. We should be a good boy who saves water by taking practical actions.
