However, when I traveled to the countryside, I found a hateful situation. On the same day, I came back from washing my hands in the bathroom and found that the faucet there was broken and a drop of clear tap water flowed out like a waterfall. I tried my best to turn it off, but I couldn't taste the taste I wanted. I'll call an uncle immediately and ask him to turn off the tap for me. But he casually said, "Don't worry, kid, this is tap water, which can't be used up. Forget it, it's okay. Open every day. " After listening to this sentence, my heart trembled: "Oh, my God! Although there are many mountains and rivers, there are times when they are exhausted. No matter how wide the sea is, there is an end. " I immediately defended my uncle's words: "Water is limited, so we should save it." He shook his head and said, "Never mind, never mind …" I really don't like his habit. "Only silently low head, to turn off the tap. Although the faucet is not completely turned off, it is much smaller than the water that was turned on before.
Seeing this, I want to tell you: "We can't live without water. Once there is no water, there is no life.
Cherish the water of life You must have seen such a public service advertisement: there is a faucet on the TV screen, dripping with water. 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. 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! In addition, the phenomenon of wasting water is also very serious, according to statistics. A medium-sized city wastes as much water as a Dongting Lake every year! 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.
65,438,000 delegates from 65 countries and regions around the world gathered in Kyoto, Japan, this month 16 to attend the Third World Water Forum, offering suggestions and suggestions for the sustainable utilization of water resources. The background of this meeting is the rapid deterioration of the global water resources situation and the increasingly serious "water crisis". According to the estimation of hydrogeologists, the total water resources of the earth is about 65.438+38 million cubic kilometers, of which 97.5% is seawater (65.438+34.5 million cubic kilometers). Fresh water accounts for only 2.5%, mostly polar ice and snow glaciers and groundwater, and only 0.0 1% is suitable for human consumption. After 1950s, the global population grew rapidly and the industry developed rapidly. On the one hand, human demand for water resources is expanding at an alarming rate; On the other hand, the increasingly serious water pollution consumes a lot of water resources available for consumption. According to the United Nations World Water Assessment Report provided by the World Water Forum, about 200 tons of garbage are dumped into rivers, lakes and streams every day, and each liter of wastewater will pollute 8 liters of fresh water; All the rivers flowing through Asian cities are polluted; 40% of the water resources basins in the United States are polluted by processed food waste, metals, fertilizers and pesticides; Only five of the 55 rivers in Europe have poor water quality. In the 20th century, the world population tripled, while human water consumption increased fivefold. Many countries in the world are facing water crisis: 65.438+0.2 billion people lack water, 3 billion people lack water sanitation facilities, and 3 million to 4 million people die of water-related diseases every year. By 2025, the water crisis will spread to 48 countries and 3.5 billion people will be trapped by water. The deterioration of ecosystem and the destruction of biodiversity caused by water crisis will also seriously threaten human survival. The water crisis not only hinders the sustainable development of the world, but also threatens world peace. In the past 50 years, there have been 507 conflicts caused by water, including 37 violent conflicts, and 2 1 turned into military conflicts. Experts warn that with the increasing shortage of water resources, the competition for water will intensify.
All life activities originate from water. Water in human body accounts for about 65% of body weight. Among them, the brain water content is 75%, the blood water content is 83%, the muscle water content is 76%, and even the hard bones contain 22%! Without water, nutrients in food can't be absorbed, waste can't be excreted, and drugs can't reach the effective parts. 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. Without food, people can live for a long time (about two months), and without water, they can live for a week at most.
