It is generally believed that there is a good supply of fresh water. But to our disappointment, the fact is just the opposite.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. What’s more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So it’s high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.
With fresh water, the world will be prosperous.
Water is very important for our life. Every day we use water to drink, too cook and to wash. Water is necessary for all plants. They need water to grow.
People can’t live without water. Plants will die without water. It is important to all living things. However, many people pollute lakes and rivers with waste water, so we must stop some people or some factories from wasting water or polluting water and help keep the water clean. At the same time we should save as much water as possible.

However, the pump suddenly a problem, Shen Yu-guang initiative to ask the next hole repair. Did not expect, the pump suddenly issued a loud noise, Shen Yu Guang was shocked into the unfathomable pool. 4 days later, his body was found.

"The happiness of the world, what is more than living in the rich water is also big?
Water, what is it? Water is the source of life. If there is no water, we will not be able to continue to survive, we can see how important water is important to us! However, people are "saving water" these five words often linked to the mouth, parents often educate us to develop such a good habit, but today I found that my mother often educated me, but even My mother did not do it.
Before dinner, I went to the kitchen to help my mother some busy, busy busy never tired, I accidentally noticed the faucet, wash basin on the faucet, the two faucets are dripping! I am surprised, and asked her mother why not tighten the two taps, my mother actually does not matter, said: "Oh, it does not matter, these two taps have long been bad bad tight, drops on the drop Well, but also how much water ah? God, how can my mother say that? To know that, every second, every minute, every time, every day, every week, every month, does not matter, then every year? How much water will be wasted every year? I can not imagine it. There are many areas of severe water shortage in the world, and we are rich in water in these areas, but in the waste of water, we simply do not know the importance of water, it is how precious ah!
In daily life, I also carefully observed that my parents do in these areas is also very good, for example: every time the wash water is poured in a bucket, accumulate together to keep mopping the ground, if the accumulation of water Really not enough then use tap water.
Drag the towel of the water to wash my battery car ... ... these methods can save a lot of water! Mom and Dad do that I think is very right, but he (she) who also made a mistake, why not tighten the faucet? If the faucet is broken, why not buy a new one? Do not care about the taps of the money, saving water is the real event, we say that I am right?
The water on earth is not inexhaustible, the real fresh water resources are not many, if everyone does not cherish, then the water on the earth will be less and less until the disappearance of water, is limited of. Friends, water conservation, treasure water resources, our mother of the earth crying, she cry for the lack of water for the body, but we should not do something?
Water is the source of life for people, something that is necessary for the growth of all things. Water, everywhere, home, nature, and we always think it does not matter, some water! Waste is not how it will be. But you are wrong, the water has been wasted by you.
When we go to the hotel to eat, whether to wash their hands found a taps did not shut, there are ticking water, then, how do you do? If nothing had happened, or to save this dripping and go up and turn off? If you close, then you save some water, but if you did not close, you know whether you have a small move, and how much water wasted.

Xiaogang took out a piece of wood, and then took out four nails, he wrote on the board: saving water. Xiaogang wood board nailed to the wall, only happily to find Xiaoming play.

With the development of industry, water pollution is becoming more serious now. The polluted water not only kills fish, it is also harmful to our health. Many people get sick because they drink the polluted water. In some rivers the water is so dirty that they can even kill plants.
We should fight against the pollution. We should stop using harmful things. I wish it is not a dream that in the near future we can have clean rivers again.
Environment Protection
Nowadays, peoples life has changed a lot with the development of modern technology and economy, which has put lots of negative effects on the environment.
Why this? Because, firstly, some factories are pouring wastes into rivers, lakes, seas and so forth; secondly, because of human activities, a great number of plants and animals are losing their lives; thirdly, using modern machines and chemicals is bad for the environment. Besides these, there are a lot of human activities which have done or are doing harm to our surroundings.
For this, I think, first, our government should make drastic measures to regulate human activities; second, we human beings should take pains-taking work to stop ourselves destroying the environment and try our best to protect our living space more.
The water is the life fountainhead, as the saying goes, the “person may not eat meal by first, but cannot on first not drink water the “humanity's life to the boiling water, the water is not the humanity lives the essential important resources.
According to the material demonstrated that, on the Earth can by the human direct use fresh water resources, only occupy the Earth 0.3%. On the Earth the overwhelming majority area all seriously lacks the water, many trees. The village and the paddies other desert swallows, the desert area is expanding gradually. The fresh water resources reduction, has affected humanity's economic development seriously, also is threatening humanity's survival. Saves the water used, protected the water resources already to cause the universe to take tructs a water source to be rich. The clear waters beautiful homeland is our desire.
However, in ours life, the waste water resources phenomenon is quite serious.. The material investigates which from us indicated that, in our real life, in ours periphery, the waste water resources situation is extremely astonishing. . Says first our school, we have paid attention, the classroom building the water hydrant sometimes the water cock has gone bad, Shui Huahua subcrust current does not water cocks are frequently drop of drop of water toward the outside drop, these did not know has wasted how much water situation, on the very many family surface looked saves the water used very much, in fact is in the waste water family kitchen and the bathroom water cock water day in day out all drops in one drop of one drop toward inside the water jar and the Chu bucket, however the water jar and the Chu bucket water in does not stop actually toward the outside flows in the sewer.
Water resources on earth are limited. But maybe some people don't know, because they waste water casually. Some people turn on the tap and forget to turn it off so that the water keeps running; others forget to turn it off because they are doing something else. This little thing is a waste of water caused by carelessness, but it is not necessary.
Here, I suggest that we must close the tap, turn off the water in time when we leave, recycle the water, such as: floor water can be used to flush toilets, rice water can be used to wash dishes and so on.
Let's start now!
Water is the source of life, life, human health without water. Few people can not eat, but you can't days without water. And now, global 20 million people are in severe water shortages!!!!!!!!!! Water crisis, has to humans was a wake-up call!
China's water resocurces, but most of all, is the sea water of the sea is salty, is not directly drinkable, Plus most all freshwater distribution in cold north and south poles and permanent snow mountain, this place is freshwater resources. And uneven distribution, east of north, south west of less than, the local water.
When I was a child I want to tap water, water has been flowing nonstop not? Mom and dad always told me what was recently and drought.
Who is willing to drink the polluted water? It can cause us to be ill and even to die. We can't wait for a moment to protect our water sources. The water we use comes from oceans, lakes, rivers or streams. But many of these water sources are getting seriously polluted. Towns and cities are pouring dust into the water. Many people are throwing all kinds of dirty things into the water. Factories are pouring waste material into the water.
Therefore, water sources have become so badly polluted that some of the water is unfit to drink or to use. Now it is high time that we should do something to protect our water environment from being polluted.
Water is very important to us. We can’t live without it. But some people don’t really care about this. They waste a lot of water, pour dirty water and throw rubbish into rivers or lakes. As a result, many rivers and lakes are polluted, and there is less and less water for us to drink. So we must do something to protect the water resource. We should stop the pollution and find ways to reuse water. If everyone can do so, we are sure to save a lot of water.
Water is the most valuable resource on the earth. Water is the necessity of our life and we must drink it , many people can not drink clear water, because many of them are badly polluted. So, in order to save water, the first thing we should do is reducewater pollution. In addition, we should develop good habits to save water.
For example,turn off the tap after we use. Or we should recycle the water to make it full use. In one word,water is scarce for all of us and we should try our best to save it.
Pollution is becoming more and more serious.
Iook at the batteries all around us. We all know that used batteries are bad for environment. We shouldn't throw them away. We should recycle them. Look at the plastic bags all around us. We all know plastic bags never rot. When we do shopping, we can use paper bags to store goods instead of plastic bags.
As a matter of fact, we can do a lot to prevent the 's do something to bring pollution under control.
Water is the source of can't live without ver,with the increasing population and industrial development,water pollution has become a serious e amounts of wastewater go into rivers and seas directly without being treated,which can be dangerous to lots of people pay no attention to saving water in daily life,while in some place water is badly needed.
It's time for us to take some measures to improve the ories should treat the wastewater before letting it go into can play a positive role in saving example we can reuse the water for wishing rice to wash vegetables and then clean a mop.

Water is an indispensable resource in our life, just as children cannot live without their mothers, and fish cannot live without water. However, some people still don"t know the importance of water to us: factories discharge a lot of sewage, making many fish and frogs lose their homes, and rivers become dirty and smelly; People do not turn off the tap after using water, and the water is lost bit by bit... I don"t know how many people get sick from drinking dirty water, or even die from lack of water.
Today, I finished my homework and came to help my mother wash clothes. After washing the clothes, I saw my mother left the water that had just been washed. I asked doubtfully: "Mom, why did you leave the water after you washed your clothes?" Mother smiled and said: "Although the water for washing clothes is dirty, if you leave the water to mop the floor and wash the toilet, you can save water." Yes, if we all save a drop of water, maybe we can save the lives of people in water scarce areas! A drop of water is a life of our human beings. I want all those who waste water to know that if there is no water, we cannot survive! Without water, there would be no life on the earth! If there is no water, then the last drop of water on the earth will be human tears! Does everyone have the heart to let this beautiful thing become a desert with nothing? Does everyone have the heart to let the beautiful earth become a colorless planet? If you don"t want to, everyone should take action and learn to save water, because water is our life.
For our homeland, for our earth, and for our future, everyone should start from me, save every drop of water, and work hard for a better future!
"Water is the source of life!" If there is no water, the earth will dry up; If there is no water, living things will perish; If there is no water, there will be no our beautiful world. We should cherish every drop of water and every tear of Mother Earth.
According to data, the freshwater resources on the earth that can be directly used by human beings account for only 0.3% of the earth. Most areas on the earth are seriously short of water. Many trees, villages and fields are swallowed by desert, and the desert area is gradually expanding. The reduction of freshwater resources has seriously affected the economic construction of human beings and is also threatening the survival of human beings. Saving water and protecting water resources have aroused great attention of all mankind.
However, how many people will save water resources? In our real life, around us, if you observe carefully, you will find that the waste of water resources is amazing. First of all, let"s talk about our school. We often find that there is no one beside the faucet in the public toilet, but the water in the faucet flows out drop by drop. A little makes a lot, which will waste a lot of water. We have also seen that the faucet or pipe in the school is broken, and a lot of water flows out. Whenever I see this situation, I will hurry to turn off the tap. If I can"t turn it off, I will tell the teacher to repair it in time.
In life, we don"t pay attention to saving water at home. For example, the water for washing rice and vegetables and washing face is poured into the sewer basin by basin. In fact, the water can be reused. I saw my mother use the water for washing vegetables. My mother said that the water for washing rice also has the function of sterilization and disinfection. The water for washing vegetables is reserved for washing dishes. The water for washing clothes and faces is used to flush the toilet. In the past, when I brushed my teeth, I always used to wash while the tap was on. My father saw it and criticized me severely. He reasoned with me and conducted field tests to make me understand how much water I would waste if I brushed my teeth once. My father took a bucket and put it under the tap for two minutes. He said that this was the water that I would waste at least once when I brushed my teeth. I didn"t know, but I was shocked when I saw it. Half of the bucket of clean water was carelessly wasted by me and went into the sewer for nothing. Since then, this bad habit has disappeared from me, and I also know how to cherish water and save water.
China does not have much fresh water resources. As the slogan says, "The last drop of water in the world will be the tears of mankind". If we waste water resources, rivers will dry up one day. "If there is no water, the wood will wither, and if there is no source, the water will be exhausted." Please start from yourself, and start now to save water!
Water is the source of life. We should protect water resources. If there is no water, trees cannot grow, flowers cannot open, life will stop breathing, and the earth will become a withered and withered planet. Therefore, we should protect this precious source of life.
Before, I didn"t know how to cherish water. I often wasted water and forgot to turn off the tap. But after a little thing, I learned to cherish and protect water resources. It was a summer afternoon. My friends and I were playing games on the grass. Suddenly, my mind flashed: we can play water gun war. Thinking of this, I went home with my partners to fetch the water gun. My water gun has a large capacity, and the water is not full.
I began to inject water into the water gun. After the water was injected, I forgot to turn off the tap and ran out of the house. After playing for a while, my mother just came back. When she saw that my tap was not turned off, she dragged me into the house, He said to me earnestly: "Water is the source of life. Many children in disaster areas cannot drink water, but you are wasting water here. Isn"t this destroying the source of human life?" After listening to my mother"s words, I lowered my head with shame, and decided that I would never waste water again in the future. I would waste my "source of life".
Human beings, water is the source of life, but it is not inexhaustible. We should protect it, not waste water, and protect the resources on which human beings depend!
Water is very important for living things. Without water there can be no life on earth.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population.

My classmates and I had an outing this spring. We had a good time. But meanwhile I noticed that water pollution in our city was becoming more and more serious.
On our way, we could see women washing clothes in the river. Litter was floating on the river. Waste water produced by a chemical factory was being discharged into the river. We did not see any fish in the river. The fiver was not so clear as before. Water quality was very bad. I am worried
about it because water is important to all living things. Man can not live without water. I hope people pay more attention to this problem, especially the government. Try to control the pollution of water as early as possible.
At last I would like to say, "To protect water is to protect life."
On Saturday, xiao Ming play his hands dirty, he went to sink to wash their hands. Wash your hands when he played, he put all the faucet is opened, but I can't go off after washing.
Xiao Ming left, small fang saw didn't turn off the faucet, hurriedly run to close the tap. Small fang ran back home and then took a piece of paper and glue, write on the paper "save water" four word, and then stick in the pool.
The next day, the small fang passing beside the pool, I saw two boys in the wash their hands while a water fight, small fang walked over to the two boys said: "you should save water, because water is the source of life". The two boys bowed his head, and secured the tap.
There is fresh water in rain, in rivers and wells. This fact leads us to think that fresh water is everywhere and it will never be used up in the world. But the fact is that such a belief is unfortunately wrong and possibly dangerous.
We know that despite the fact that seventy percent of the earth＇s surface is covered with water, only a little part of it is fresh water. Yet the demand for fresh water in our daily life and in industry seems great. Moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. It is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. What is worse, more and more water resources are being polluted, making the water unfit to use.
We still have time if we begin to act right now. We must warn the people of the importance of fresh water and the danger we are facing. We should control the wastes produced by factories. We should also develop new ways to use our limited fresh water more economically and recycle the used water. In short, the global shortage of fresh water can be solved if some measures are taken right away.
People can＇t imagine life without water. Without it, the earth we live on would be a dead one. There would be no trees, no crops, no animals and no people. So water is considered to be next to oxygen in importance.
Although nearly three quarters of the earth＇s surface is covered with water, it is sea water and undrinkable. The demand for water is increasing, while water resources are scarce. Agricultural production needs enormous amounts of water, so does industry. Besides,the rapid growth of population makes it more and more difficult for people to survive because of the water shortage. So water shortage has become one of the most serious problems.
Fortunately, people have realized this pressing problem and are trying to find ways to salve it. First, people are urged to economize on water. Second, measures are taken to protect water resources. Third, circulating water is used for industrial purposes over and over in factovies and treated sewage water is used for irrigation in farming land.
Directions: For this part, you are allowed 30 minutes to write a composition on the topic Global Shortage of Fresh Water. You should write at least 100 words and you should base your composition on the outline (given in Chinese) below.
No creature can live without water and human being is not an exemption as well.
Our body is mainly formed by water, about 70% or more.
So everyday we need to drink a lot to keep ourselves healthy and full of energy.
Except that, there are lots of things we need water in our daily life.
We need to use water to cook, to wash clothes, to shower and so on.
As we know the water shortage is a big issue all over the world. Therefore save water is very important in our life.
Hello, my name is water. Life, everywhere. Wash and brush, wash hair, cooking, cooking, washing clothes.
You see how important life everywhere, I cannot, so everyone should cherish, saving water blessing.
Everybody must be hard, vying for saving little angel!

Water is the basic source of life. There would be no life without water.
More and more water is needed in the modern society.
Many places are short of water; many rivers and lakes are polluted.
What’s worse, many people are wasting water.
In order to protect water, let’s do something to fight against all kinds of pollution and waste of water.
In recent years, water becomes more imporant,so how we protect the water from the pollution.
To begin with,All of the creatures made of the water,water is essential things that we live in the earth.
So we can't live without over,we can use water that we wash our faces with to flush the toilets,
In general,We should learn how to save water and make water management an important part of our life.
We have only one earth. But now, the environment becomes worse and worse. As you know, there's no enough clean water for people. So many of them lose their lives because of water. In a lot of countries, people have to cut trees for living.
So there's nothing to keep water from running away. Also we have polluted the land, the river and the air. So we have to face more and more floods and droughts . It's time that we must do something useful to protect our environment. We can plant trees and take good care of them. We can save the water and ask our parents to do so. We can't throw any litter onto the ground and we should collect them for recycling. If we take good care of our earth today, it will be more beautiful tomorrow. As you know,t here's no enough clean water for people. So many of them lose their lives because of water.
Presently, the world is faced with serious water problems. but these problems witt become more intense and more comple in the future. our increasing population witt tremendously increase urban waters, primarily sewage. on the other hand, increasing demands for water witt decrease substantially the amount of water available for diluting wastes. rapidly epanding industries which involve more and more comple chemical processes will produce large volumes of liquid wastes. many of thesewitt contain chemicals that are poisonous. to feed our rapidly epanding population, agriculture will have to be intensified. this will involve ever increasing quantities of agriculture chemicals. from this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problems.
There are two ways by which these pollution problems can be lessened. the first relates to the treatment of wastes to decrease their pollution hazard. this involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes to permit the reuse to the water or best reduce pollution upon final disposal. the second approach is to develop an economic use for all or part of the wastes. farm manure is spread in fields as a nutrient. wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. liquid wastes from other processing plants may also be used as a supplemental source of water. only by doing these promptly now can we epect to solve the serious water problems in the future.
We live in the earth which is surrounded by the water, water is very important to people’s lives, no one can live without water. Electricity is also important, we can see in the night and so many things we use must work with electricity. Water and electricity are precious resources, we should save them and use them in recycle.
Saving these precious resources makes a contribution to people.
It is generally believed that there is a good supply of fresh water. But to our disappointment, the fact is just the opposite.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. What's more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water.
Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So it's high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.
With fresh water, the world will be prosperous.
The world is not only hungry,but also thirsty for water.
This may seem strange to you, since nearly 75 % of the earth's surface is covered with water. We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. eriments have already been done in this field, but only on a small scale.
For us, the systems are as important as the spacecraft.
Water is very important in our drink it every day and use it to cook and wash can not live without how can we save water?
There are several ways to save water.
Firstly,take shorter showers and don’t leave the tap running when we don’t need to use ndly,Try to reuse water ’s the most important way for us to save last,We should not pollute water so that we willl have fresh water for years and years.
If we do not save water,the last drop of water will be a protect water is to protect our life.
We have only one earth. But now, the environment becomes worse and worse. As you know, there's no enough clean water for people. So many of them lose their lives because of water. In a lot of countries, people have to cut trees for living. So there's nothing to keep water from running away.

With the development of modern industry and the growth of population, water shortage has become a growing concern for Chinese government and people.
Several factors contribute to this problem. On the one hand, water supplies are being consumed by a growing number of heavy industries as well as the growing population. On the other hand, many rivers and lakes have been polluted. What’s more, the well-developed root system of trees can keep the water from diffusing into the earth, but deforestation at the upper reaches of rivers has made the situations worse.
To solve the problem, several measures can be taken. First, we must economize the use of water resources and practice a recycling policy. Second, stricter laws and regulations should be implemented to protect the limited water resources we have. Finally, more diversion projects should also be used so as to direct the surplus water resources in the Southern Chine to the under-supplied regions. In a word, stronger measures can and should be taken to protect the water resources we have now.
To sum up, water shortage is already serious in China these days. It is high time for us to do something to prevent it from being worse. Therefore, if everyone takes action to save water, the situation will be better.
Hello everyone, I am Chuck. Today, I want to tell you something about water resources.
Water is one of the indispensable conditions to human survival. If there no water,there would be no life existence. Water is like a great gentle mother who gives us life, so we should protect water resources to show how much we love it!
Although about three-quarters of the global area is covered with water, only one percent can be used. Lack of freshwater resources is a common problem in the world. One of the reasons is that the global freshwater resources have a uneven distribution. And the other reason is wasting water.
China is one of the most water-short countries in the world. It has less than 1/4 of the world average water. By this token,we all can see how important the freshwater resources are for us. According to statistics, there are about two-thirds of the urban cities on a national scale that don’t have enough water to use. In the area of Loess plateau, the water consumption per capita only has about 23 liters. What an appalling number it is！
But in our daily life, we can see the scene of wasting water everywhere. We usually see the tap running water but nobody turns it off. And the water pollution in our life is also a common behavior. People always use excess laundry soap to wash clothes, and it always makes pollution.
Today the water resources are more and more important. In order to make the last drop of earth's water is not our tears, let’s take actions,use our practical action to save water!
Saving water means saving our life!
Thank you for your attention!
Since 1900, the U.S. has pulled enough water from underground aquifers to fill two Lake Eries. And in just the first decade of the 21st century, we've extracted underground water sufficient to raise global sea level by more than 2 percent. We suck up 25 cubic kilometers of buried water per year.
That's the message from the U.S. Geological Survey's evaluation of how the U.S. is managing its aquifers. Or mismanaging. For example: water levels in the aquifer that underlies the nation's bread basket have dropped in some places by as much as 160 feet.
The rest of the world isn't doing any better. A conference of water scientists just issued the so-called Bonn Declaration, which declares that this lack of foresight will cause the majority of people alive in 2050 to face "severe" freshwater shortages.
Mismanagement of water resources is a hallmark of this new human-dominated era in the Earth's geologic history, known as the Anthropocene. Despite building, on average, one large dam every day for the last 130 years, we use more water than we store. And we're letting that freshwater escape to the seas. Which means we may find ourselves with water, water everywhere, but not much fit to drink.
Israel knows how to deal with drought. The small Middle Eastern country has experienced dry weather conditions and water shortages for many years. The American state of California is in the fourth year of a drought. So a Jewish group proposed a conference to show Californians what Israelis can offer in terms of technology, knowledge and support.
Barry Broad is head of the Sacramento Jewish Federation. He says the idea for the meeting wasa product of Sacramento's Sister City relationship with the Israeli city of Ashkelon.
"We thought given California's water situation -- we're in a very serious drought -- and Israel'sadvanced technology in this would be the perfect Sister City event to plan. Bringingexperts from Israel to tell us what are the things we can learn from Israel's longer and moreextensive history dealing with life in a permanently arid climate."
In California, hundreds of thousands of people pay a flat rate for their water. In other words,they pay the same amount, whether they use a lot of water or very little.
Israel treats water differently. Eilon Adar is director of the Zuckerberg Institute for WaterResearch at Ben-Gurion University in the Negev desert. He says water is considered a nationalresource, like oil or natural gas. The Israel Water Authority sets the price of water. Mr. Adarsays that the more water someone uses, the more they must pay.
"In my country, when I buy a unit of water to my house, I pay for the water as a commodity; Ipay for the transmission, and I pay for the treatment of the water released later on from myhouse. And this, I think, is the key for success."
Israel has five desalination plants in operation. They remove salt from sea water so it can bedrunk and used to cook and clean clothes. More than half of the water for homes, farms andbusinesses comes from this desalination process.
A desalination plant will soon begin operating near the city of San Diego, California. CaliforniaGovernor Jerry Brown has called for a 25 percent reduction in the use of water. And inNovember, voters approved a plan for the government to raise money to help solve the state'swater problems.
Mr. Adar says the biggest barrier to solving California's long-term water problem may havemore to do with politics than technology. He says large cities in the southern part of the statedemand fresh water from the northern part.
Darryl Steinberg is the former president of the California Senate. He says cities throughout thestate have to stop fighting each other for water.
"Truth is, we don't have room for division here. It's one state. There's less water. There's morepeople, and we're going to have to be much more aggressive and come together in a muchmore effective way over time, if we're going to deal with this. And I'm confident we can."
Mr. Adar says farmers, property owners and water companies must work together to savewater. He says Israel will use its advanced technology, information and experience to help anycountry that asks.
Scientists may have found one answer to the problem of water shortages. It is a new material that collects water from the air. They got their idea from a small beetle that lives in the desert in Africa. The deserts of the Skeleton Coast in Namibia are very dry, but the Namib desert beetle is an expert at surviving in hot and dry conditions. Its shell is covered in small bumps that collect tiny water droplets from the air. The water is enough to keep the beetle alive. Scientists studied the shape and material of the beetle's bumps. They want to use what they found out about the beetle to make their own materials that can collect water from the air. This will help people who live in very dry areas.
The scientists believe this new technology could help in many areas of our life. They said it could be very useful for power plants and for the heating and air conditioning in airplanes, cars and trains. One of the scientists, Philseok Kim, said: "Thermal power plants, for example, rely on condensers to quickly convert steam to liquid water. Our design could help speed up that process and even allow for operation at a higher temperature, significantly improving the overall energy efficiency." Another scientist, Joanna Aizenberg, said she was looking forward to the future of getting ideas for new technologies from nature. She said: "Everybody is excited about bio-inspired materials research."
Water is the source of can't live without ver,with the increasing population and industrial development,water pollution has become a serious e amounts of wastewater go into rivers and seas directly without being treated,which can be dangerous to lots of people pay no attention to saving water in daily life,while in some place water is badly needed.
It's time for us to take some measures to improve the ories should treat the wastewater before letting it go into can play a positive role in saving example we can reuse the water for wishing rice to wash vegetables and then clean a mop.
