Simple, beautiful and thrifty blackboard newspaper content 1 water, the basic substance on the earth, how worthy of 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? So? Water is the source of life? It is no exaggeration.

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. Of the remaining 2.5% fresh water, the water that humans can really use is less than 1% of the global total fresh water. More than half of the countries in the world have a population of about 654.38+0.5 billion, of which 450 million people in 29 countries are in a state of water shortage. ? Water is as expensive as oil? These four words are a metaphor, but in many parts of the world, they have become an indisputable reality. 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 thought that there is a limit to the endurance of water, 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, it is in this emergency that we humans continue to waste and destroy water resources. Because a large amount of industrial wastewater is discharged into Lian and Rong rivers, the water quality of the two rivers is seriously polluted, and the water quality only reaches the third class standard, so it can neither be drunk nor used for irrigation. Does an island county like South Australia depend on water? According to God's arrangement, the rainwater harvesting area of all Shantang reservoirs including flood diversion works only accounts for 365,438+0%, and it is still difficult for industrial and agricultural production and people's domestic water use. It can be seen that it is urgent to properly handle the pollution and destruction of water resources. However, there is a serious shortage of water resources in the world today, and wars caused by water are increasing day by day. For example, among all the resources in the Middle East, water is the most likely to cause crisis, and water in the Middle East is more expensive than oil. Most countries in the Middle East are seriously short of water. The Middle East has suffered from drought for more than ten years and is facing a serious water crisis. The only way is to save water, and in this respect, Israel has done better. Two-thirds of Israel is desert, and there is no rain for seven months in a year. The per capita water resource is nearly 70 cubic meters, which is less than 1/4 in the Middle East, 3% in the world and 1/8 in China. However, it is in this barren and water-deficient land that Israel has built modern agriculture through scientific water use, which has amazed the world.

Agriculture was once the foundation of Israel. 1952, Israel spent 10.50 billion dollars, and it took10 years to build 145 kilometers. South-to-North Water Diversion Project? In the mid-1960s, the scientific water use method of drip irrigation was popularized in water pipelines, which promoted the rapid development of agricultural economy. The agricultural population in Israel has dropped from 60% to 3%, and a farmer can support 90 people, with a per capita GNP 1 80,000 USD, ranking first in the world 12. Israel cherishes water resources very much and regards water as its lifeline. Saving water is a systematic process, involving all aspects of society. Therefore, success has been achieved.

Water makes green grass greener.

Simple and beautiful thrifty blackboard newspaper content 2 When I was old enough to learn ancient poems, what was the first ancient poem I learned? At noon in summer, the sun is very hot, farmers are still working, and beads are dripping into the soil. Who knows that every grain of Chinese food is hard? ? Everything we were late was watered by the farmer's uncle with hard sweat. At that time, I felt that children who grew up in the old society were not as happy as we were, but they had a good habit that our children rarely have now, that is, the good habit of thrift they developed in difficulties. This habit is rare among our children now, because we are all treasures at home, grew up eating honey, and developed the habit of wasting since childhood, and we don't know what saving means at all. Such children will grow up to be absent, greedy and unable to work. Those children who have developed the habit of thrift since childhood will work hard and will not waste too much. Such children will become promising people when they grow up.

Actually, saving is very simple. For example, if each of us saves a grain of rice every day, the poor can eat delicious rice. If each of us saves one degree of electricity every day, we can make the places lacking electricity light up; Each of us saves a drop of water every day, so that people who can't drink water can drink it for a year; If we save a dime or even a penny every day, we can let the children who are eager to go to school go to school, let the hungry and cold get food and warmth, and let the homeless return home. These things seem insignificant to us, but as long as all people in our country are frugal and all people in our country can form the habit of thrift, then there will be no famine, water shortage, electricity shortage and oil shortage in our country.

Saving is a kind of consciousness, virtue and wisdom, and saving should become a habit and style of people. For individuals, saving is a scientific way of life; To society, economy is a civilization. If you can start with me from now on, remember the consciousness of saving, and start with saving electricity, a drop of water, a piece of paper and a grain of rice, our world will become more beautiful.

Students,? Make saving a habit, a way of life? , start from me, start from bit by bit!
