I once read an article called Taohuaxi People Talk. The story goes like this: in the western suburbs of Chongqing, there is a small stream called Taohuaxi, which has been flowing for decades. It turns out that the stream is crystal clear and there are many peach trees planted next to it. The trees are full of peach blossoms, which often attract swarms of butterflies and bees. Therefore, many children will play by the stream, while listening to the singing of the stream "Ding Dong, Ding Dong" and enjoying the beautiful peach blossoms. What a wonderful thing! However, how do ruthless humans treat the flow? They threw a lot of domestic garbage into the stream, and some factories near the stream discharged a lot of sewage and waste. The stream changed from a beautiful little girl to an ugly old woman, and a beautiful stream was destroyed in this way.
Humans! Don't you know? How important water resources are to us! Now, countless streams, rivers, lakes, rivers and oceans are calling on us: "Help us ..."
This example gives us a wake-up call, there is only one earth in the world! Let's take action, protect the environment, beautify our homeland, keep green mountains always there and green water always flowing!
Chapter II Protecting Water Resources and Being an Environmental Citizen Dear teachers and classmates,
Hello everyone! The topic of my speech today is: protect water resources and be an environmental citizen.
Water is the source of all life. 60% of human body weight is water and 90% of blood is water. Each of us needs two kilograms of water every day to maintain life. Water is the main resource in production: it takes 65,438+0,400 cubic meters to produce one ton of rice, 200 cubic meters to smelt one ton of steel and 500 cubic meters to produce one ton of paper. It can be said that without water, human beings can't survive.
Students, in the hot summer, when you turn on the tap and take a cold bath comfortably, do you know that the water you use for bathing is the daily water consumption of dozens of people in water-deficient areas? When you flush the toilet, your disposable water consumption is equivalent to the per capita daily water consumption in developing countries; When you accidentally tighten the faucet, the water it loses in one night is equivalent to the drinking water of a village in a water-deficient area in Africa or Asia in one day ... These examples are by no means sensational, but the conclusions drawn by relevant UN agencies after years of investigation.
As we all know, China is a water-deficient country, with per capita fresh water of only 2,240 cubic meters, which is less than a quarter of the world average. It ranks 109 in the world and is listed as one of the 13 countries with severe water shortage in the world. Due to the lack of water, China's rural grain production has been reduced, and desertification is serious in northwest China, with frequent sandstorms. Saving water is the top priority for each of us in China.
However, looking around, the phenomenon of destroying and polluting water resources is common.
Students, "Gold is valuable, but water is priceless". For our own health, for the future survival and development of mankind, let's take active actions, start from the small things around us, start from bit by bit, save water, protect the water resources we depend on, and be an "environmental citizen" who cherishes water like gold! Let/"the last drop of water on the earth/will be the tears of mankind"/such an advertisement/become an advertisement forever!
Thank you!
Chapter III Protection of Water Resources Water is our precious resource. We use water every day: cooking, washing vegetables, washing hands, washing faces, bathing, even vehicles, and almost all objects use water. With water, we have this beautiful life. In the past, the water in the river was crystal clear, and you could almost see small animals and algae at the bottom of the river. When fish of all sizes see that you want to catch them, they will run away at once, but the clear water helps us. Those fish want to escape to other places. When we see where they swim, we stand in front of them so that the fish can't escape.
Now, the water in the river suddenly turns black. People keep building factories, and society has become modern. Excellent composition 400 words, "400 words to protect water resources". The discharged waste gas and sewage blacken rivers and water in other places. In some areas, the river stinks to death, so people should hold their noses when they walk by. The water in the river is polluted, and the pests will be happy. This river is full of thousands of mosquitoes and flies in Qian Qian. People use lunch boxes, plastic bags, residual branches and leaves, discarded umbrellas, broken balls, feces pulled by animals and countless rubbish. People can see sewage discharged from pipelines along the river bank everywhere. We'd better go swimming less in summer to avoid being hurt by sewage. The exhaust gas from the factory is black, which will also pollute the water body.
We should protect water resources. Water is the source of our life. Let's not litter everywhere. Society should protect water resources. We should throw the garbage in order and put the cans in the yellow trash can; Put the lunch box in the white trash can; Put daily necessities in the green trash can; Put the paper in the red trash can. We not only throw rubbish everywhere, but also form a good habit of saving water.
We usually don't play with water whenever we have time. Some schools have set up several special places to wash their hands, but some people turn on the tap very loudly and seal the drain, so that more and more water flows in the basin and precious water is wasted. At present, the water on the earth accounts for 70% of the whole earth. Don't think there is so much water. Not 70% water can be drunk, only 10% water can be drunk, and the rest can't be drunk. Even this poor water, human beings still don't cherish it. At present, some countries are competing for oil. If we humans continue to pollute water resources in this way, we may cause a tragic water war in the future. The whole world should cherish water resources and save water, so that human beings can have a colorful life.
Chapter IV Protection of Water Resources 550 words In our world, the most precious thing is not gold, silver and jewels, not delicacies, but water, which is the resource and the foundation of life. Without water, we humans can't survive.
I remember when I was a child, my mother took me to my grandmother's house to play. There is a clear stream in front of grandma's house. You can clearly see the sand and stones at the bottom of the river. Look at the lively and lovely little fish jumping, and from time to time there are small fish spitting bubbles! I can't help rolling up my trouser legs and barefoot, which makes me feel its coolness and softness. Beautiful and lovely waves roll up and down, like blooming water lilies. Listen, the stream is singing a beautiful and moving song!
But not long after, when I came to my grandmother's house again, I saw a dirty and smelly stream, and the crystal clear stream was gone. I saw a lot of rubbish floating on the water, and I couldn't hear the beautiful song of the stream anymore. Small fish are not so active, and they gradually lose their lives. I feel so sad that I want to cry. Why become so ugly?
When I got home, I felt terrible. If human beings do not protect nature and water, then our life will lose happiness and life.
Friends, let's take action together! Call on our family and friends to save water and make good use of waste water. In addition, we should also remind those who cut down indiscriminately not to destroy our beautiful home again.
As long as we realize the importance of water in our bones, I believe that as long as every citizen knows how to cherish and cherish our water resources, the water source will definitely shine again! It will always be beautiful, surrounded by green trees, and it will always be our lovely home!

Chapter V Protection of Water Resources 650 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!
Chapter VI Protection of Water Resources 700 Water is the source of life, the foundation of life, and people's 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! ! The water crisis has sounded the alarm for mankind.
Although China is rich in water resources, most of it is seawater, which is salty and can't be drunk directly. In addition, most of the fresh water is distributed in the mountainous areas with perennial snow in the North and South Poles, and there are few fresh water resources left. And uneven distribution, less in the east, more in the south and less in the north, leading to serious water shortage in most places.
When I was a child, I thought, isn't tap water always flowing? Dad often tells me that that place is short of water again, not to mention planting crops, and even drinking water is difficult to solve. He also often warned me to save a little when using the faucet in the future. I thought to myself: Isn't there a lot of water in the world? Why is there such a serious water shortage?
Later, I gradually understood through learning, and I gradually understood. It turns out that China has only 28,000 cubic meters of fresh water resources, but the per capita water is only 2,200 cubic meters, accounting for only a quarter of the world's per capita. The world ranking is 1, 3 1, and it is one of the countries with 13 water shortage in the world. There are 600 cities in China, and 400 cities are short of water at present. Now every time I use water, I think I can save a little, at least I can save some people!
But this grim situation has not attracted people's attention. Now the pollution of rivers and lakes is very serious! Some factories often discharge industrial waste into rivers, and some people throw the garbage from picnics by the lake into the lake ... All these phenomena lead to water pollution, which means more people will be short of water! As long as I see this situation, I will stop it at once. Although I was scolded a lot, it didn't stop my progress! At that time, I felt that there was always a belief in my heart: protecting water resources is my responsibility and everyone's responsibility.
