Speech on saving water on campus 1 Dear teachers and students:
Hello everyone!
Water is the source of all life. It is because of water that this beautiful blue planet is created, and that human beings, animals and plants can survive.
What if there is really no water? Then the earth will be as lifeless and lifeless as Mars and Saturn. Then, there will be no humans, trees, flowers and everything else. Flowers will bloom when watered, and green leaves will be beautiful when moistened. Will the flowers bloom if there is no water? Can the stream sing? Can birds fly? Will the young trees flourish? The answer is self-evident.
Water resources are limited. There are very few fresh water resources on land. Although the surface of the earth is covered with 70% water, most of it is seawater, which is salty and cannot be directly used. However, fresh water resources only account for 2.53% of the total water bodies on the earth, and nearly 70% of them are solid glaciers, that is, alpine glaciers distributed in polar regions and low latitudes, which are still difficult to be utilized. At present, the freshwater resources that are easy to be used by human beings are mainly river water, fresh lake water and shallow groundwater, accounting for about 0.3% of the global freshwater reserves and only 7/100000 of the global total water storage.
In daily life, water is always wasted unconsciously. Washing vegetables should be done basin by basin. If you turn on the tap, a meal will consume 50 kilograms of water. Washing clothes with a washing machine will consume 120kg of water twice. Washing vegetables with rice washing water and then washing them with clear water can not only save water, but also effectively remove pesticide residues on vegetables. Wash the mop, sweep the floor and flush the toilet.
The second washing water for washing clothes cleans doors and windows, furniture, shoes and socks, etc. Flush the toilet after defecation, try not to turn on the big water pipe for flushing, and make full use of the used "dirty water". If you turn off the tap and rub soap in the shower, you can save 60 kilograms of water in the shower. In summer, indoor and outdoor ground sprinkles water to cool down. Try not to use clean water, and use washing water after washing. When cleaning bicycles and family cars, use wet cloth instead of water. Where it is too dirty, it is also advisable to wash it with the water left over from washing clothes. Water the flowers at home with rice washing water, tea, laundry water, etc. Household washing towels, small objects, fruits and other small amounts of water. It is better to hold water in a basin than to turn on the tap to flush it.
If everyone has no awareness of saving water, if water is really as expensive as oil, countless people will die of thirst, and the last drop of water on the earth will become a tear that people regret!
Cherish water resources and protect water environment. Sewage treatment system, strengthen water environment monitoring, strengthen legal awareness, and manage water resources and water environment according to law.
Saving water is beneficial to the present and the future. Therefore, I call on everyone to save water, save water from now on, cherish water and cherish and protect water resources. Start from me, start from the side bit by bit!
Speech on saving water on campus 2 Dear teachers and students:
Hello everyone!
Seen from space, the earth is like a blue ball, with a lot of water,1* *1.45 billion cubic meters. How can it be short of water if so much water is inexhaustible? In fact, more than 97% is seawater, which is bitter and salty. How can I drink it? Besides, it can't be used for irrigation, so it is difficult to be used in industry. The fresh water that can be directly used by people in production and life is pitiful, only more than 2.5%, of which 70% is frozen in the north-south level and frozen soil far away from human beings and cannot be used.
A person who doesn't have enough water can't live for a week under normal circumstances. However, as long as there is water, even if there is nothing else in the desert, at least it will last until next month; Without water, plants can only last for a few days even if they germinate. And when there is a little moisture and sunshine, it will try to grow up and thrive. The food we produce is even more inseparable from water. According to statistics, corn 1 kg uses 368kg of water, wheat 5 1 3kg of water, cotton 648kg of water and rice 0/1,000kg of water.
With the increase of population, water resources are getting less and less, and the quality of water is getting worse and worse due to agricultural pollution and chemical pollution. With so little fresh water, people still waste and pollute water resources extremely. The World Summit on Sustainable Development held in South Africa has listed the water crisis as one of the most serious challenges facing mankind in the next 10 year. By 2025, nearly half of the population will live in water-deficient areas, and water-deficient or water-deficient areas are expanding. In Africa, there is a serious shortage of water resources, and thousands of people die because of drinking problematic water or no water. For them, water is the supreme treasure!
Nowadays, people are less and less saving water. Maybe when the radio will send out such an alarm: "In a few months, the water will disappear." At that time, it was discovered that the price of a drop of water was equivalent to the price of a drop of blood. What a terrible thing!
Therefore, saving water and protecting water resources have become the top priority now! Each of us should start with me, from now on. For example:
1, rice washing water can be used for washing face, watering flowers, mopping floor and flushing toilet;
Don't leave the shower nozzle on all the time, but let the water shower intermittently. Turn off the water in time when scrubbing;
3, clothes should be washed centrally, reducing the number of laundry; Moreover, advocating hand washing for small items such as underwear, socks and summer clothes can save a lot of water.
Don't forget to turn off the tap after washing your hands!
Save water! Everyone should start with me, from now on!
Speech on saving water on campus 3 Dear teachers and students,
Hello everyone!
Today, the topic of our national speech is "Whether we know it or not, let's protect the environment together".
Let me tell you a little story first. A certain media once held an essay contest with the theme of "environmental protection". Entries poured in, and many people put forward their own opinions on how to protect the environment. However, the final winner is an ordinary student. He contributed an ordinary article, but how did he stand out? Faced with doubts and doubts, the judges took out thin entries and said, "His article may not be the best, but he is the only one who wrote it on the front and back of the manuscript paper. If everyone saves paper as he does, then we will save towering trees. In the face of many environmental protection coups, only he did his best and really achieved environmental protection! "
Indeed, in the face of "doing", any gorgeous rhetoric has become eclipsed. Protecting the environment and caring for trees don't need too many slogans. What it needs is practical actions, "doing" one by one. However, many times, we didn't "do it". The towering trees fell in the harsh sound of the chainsaw, leaving only bare stumps in the lush forest. In the eyes of some people, forests can only provide wood and have no other use. In fact, the role of forests should not be underestimated. China put forward the development concept of "innovation, coordination, green, openness and enjoyment", among which "green development concept" is an important content. Protect the ecological environment "We need both Jinshan Yinshan and green mountains and green hills. Together, we will build a beautiful campus.
When we are in nature, will we feel relaxed and happy when we see gurgling streams, tinkling springs and quiet lakes? It will also sigh, "How much energy does a drop of water have?" A drop of water can moisten the wheat field and produce grains; A drop of water can quench thirst and create magic; A drop of water can reflect sunlight and create beauty. These are people's compliments on water.
Students, on today's flag-raising platform, I also want to show you the theme poster released by the Ministry of Water Resources. They pay close attention to the publicity theme of World Water Day this Friday.
Students, since forests and water droplets are so important to us, what can we do for them?
Next, on behalf of the school brigade, I would like to propose the following initiatives to all the students:
1, don't throw litter everywhere, and take the garbage to the designated place.
2, do not trample on climbing flowers and trees at will, and be a civilized observer.
3. Save water and protect water resources like eyes.
4. Bring green into the classroom, into the campus, into the family, and let the breath of spring be everywhere around us.
Sow a green seed today and reap a blue sky and green land tomorrow! Protecting the campus environment is everyone's responsibility! Students, protect the environment, let's work together!
My speech is over, thank you!
Speech on saving water on campus Dear teachers and students,
Hello everyone!
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 is no water on the earth, Mother Earth will not give birth to our offspring for generations to come. 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. In the hot summer, when people feel unbearable heat, if only it could rain! 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! For example, the water consumption for a picnic. 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.
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.
There is also water, 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 drink boiled water, but they drink tap water with their mouths to the tap, and the sound of water doesn't hurt at all.

Speech on saving water on campus 5 Dear teachers and students:
Hello everyone!
Students, when you turn on the tap to have a water fight, when you hear the bell ring and run to the classroom and forget to turn off the tap, you will know that you have made a big mistake! That is "wasting water resources"!
Water looks so ordinary that people can forget it at any time. People only think of drinking water when they are thirsty, but they seldom or never care about water itself. Without water, there would be no life, let alone life civilization and development. At present, due to the rapid increase of the world population, excessive demand and waste of human beings, industrial pollution and other reasons, the world's fresh water resources are increasingly scarce, and human beings are facing a serious water crisis.
China is also a country short of water resources. Although the total water resources reserves reach 2.8 1 trillion cubic meters, ranking sixth in the world, China has to feed a quarter of the world's population, and the per capita water resources are less than a quarter of the world's per capita water resources. It is listed as one of 13 countries with poor water resources in the world. Experts predict that the population of China will reach the peak of 65.438+0.6 billion in 2030. Coupled with the increasingly serious water pollution, by then, China will become a country with serious water shortage.
Listen attentively, the Huaihe River is shouting, the Yellow River is crying, and the Yangtze River is sighing ... Water pollution, like a persistent chronic disease, plagues rivers, lakes and reservoirs, and the deterioration of the water environment directly threatens people's health. In order to appeal to people to pay attention to water pollution and save water resources.
Dear students, do you know? After years of investigation by relevant United Nations agencies, the results are as follows: the water consumption for flushing toilets is equivalent to the per capita daily water consumption in developing countries; The water used for bathing in summer is equivalent to the daily water consumption of dozens of people in water-deficient countries; When the faucet is not tightened, the water lost in one night is equivalent to the total amount of drinking water in a village in Africa or Asia in one day. This shows how important it is to save water!
Dear students, we are the little masters of the country. You should develop good ideas and habits of saving water from an early age, whether at school or outside school. We should take practical actions from now on and be a good boy to save water together!
