How should we protect water resources?

How should we protect water resources?

First, start from the small things around you, save water in your life, and don't waste it indiscriminately. Second, when traveling or passing through lakes and rivers with water sources, pay attention to environmental protection and don't throw things into the water. Third, advocate the conservation and recycling of water resources, and always warn people around you to join the ranks of environmental protection.

How to protect water resources?

Water is the source of our life, and we should protect water resources. We can't form the bad habit of littering. We should put the rubbish into the dustbin in order. There is phosphorus-free washing powder; You can also use more water, such as washing vegetables, watering flowers, washing your face and flushing the toilet. Don't pour all the sewage into the river. Although you poured less. If you pour it together, it will become black water!

How to protect water resources

What should we do in the face of this severe water resources situation:

1, you should have the consciousness of cherishing water. Only when you realize that "saving water is glorious and wasting water is shameful" can you pay attention to saving water all the time.

2. Develop good habits,

3. Use water-saving appliances,

4. Leak detection and plugging. As far as production is concerned, especially for some industries with large water consumption, we should focus on how to optimize the implementation of water system, how to improve the concentration multiple of reclaimed water and how to improve the recycling rate of water resources, and actively organize technical research to improve the comprehensive utilization rate of water; At the same time, a feasible operation system is formulated to manage the water consumption of products in quota, which is used as a technical and economic index for assessment to reduce waste.

Many people imagine the earth as a blue planet with 7 1% surface covered by water. In fact, 97.5% of the water on the earth is salt water and only 2.5% is fresh water. In fresh water, nearly 70% is frozen in the ice sheet of Antarctic and Greenland water pollution data, and most of the rest is soil moisture or deep groundwater, which is difficult to exploit for human use. Water from rivers, lakes, reservoirs and shallow groundwater is easy to be exploited for human direct use, but its amount is less than 1% of the world's fresh water, accounting for about 0.007% of all water on the earth. The annual precipitation of water data falling on the mainland in the world is about 1 10 trillion cubic meters. Excluding atmospheric evaporation and water absorbed by plants, the global river runoff is about 42.7 trillion cubic meters. According to the world population 1995, the per capita annual water consumption is 7300 cubic meters. Due to the increasing world population, this average is 37% lower than that of 1970.

[Edit this paragraph] The water pollution problem in China.

If you don't cherish it, the last drop of water is equivalent to blood (the cry of nature's grief and indignation)

Seven major water systems, namely Haihe River, Liaohe River, Huaihe River, Yellow River, Songhua River, Yangtze River and Pearl River, are all polluted to varying degrees.

The situation along the coast of Wan Li is also not optimistic, with red tides coming as scheduled every year. In the beautiful Bohai Bay, turbid water splashes, and the oil floating on the sea burns life in the ocean like a black torch.

With the gradual development of science and the gradual increase of high-rise buildings, the problem of water shortage is becoming more and more serious. With the destruction of mankind, the original blue "crystal ball" is no longer Ming Che, no longer blue, and will soon dry up.

Although 7 1% of the earth's surface is covered with water, in fact, fresh water resources only account for about 2% of the earth's total water, and the total amount of fresh water available to human beings only accounts for three tenths of the earth's total water, accounting for 0. 34%。 It can be seen that there is not as much water available on the earth as humans think. If it is allowed to continue to be destroyed by human beings, it will disappear sooner or later.

First of all, we should establish the consciousness of cherishing water and carry out water resources warning education. For a long time, most people generally believe that water is an inexhaustible "cornucopia", which is wasted in use and does not know how to cherish it consciously. In fact, the water resources on the earth are not inexhaustible. Especially in China, the per capita water resources are not rich, the regional distribution is uneven, and the year is unpredictable, with great inter-annual differences. Coupled with serious pollution, water resources are even more scarce, which is vividly reflected in the repeated water cuts of the Yellow River. National water resources utilization projects such as "Yellow River Diversion Project" and "South-to-North Water Transfer Project" are aimed at solving the water shortage problem in some areas, but we should think deeply: Where can we "divert water from the Yellow River" when the water in the Yellow River is exhausted? The water in the south is polluted. How to "transfer water to the north"? Therefore, people must establish the consciousness of water crisis, take saving water resources as our conscious code of conduct, and carry out water resources warning education in various forms.

Secondly, we must develop water resources rationally to avoid the destruction of water resources. The development of water resources includes the development of surface water resources and groundwater resources. When exploiting groundwater, because the water quality between aquifers is very different, it should be exploited in layers. Contaminated diving and confined water shall not be mixed; For exploration projects that expose and penetrate the water layer, layered water sealing and hole sealing must be carried out in strict accordance with relevant regulations to effectively prevent water pollution and ensure the sustainable development of water bodies.

Modern water conservancy projects such as flood control, power generation, shipping, irrigation, aquaculture water supply, etc., while exerting one or more economic benefits, will also have a certain negative impact on the natural and social environment of the project location, upstream and downstream, estuaries and even the whole basin, and may also cause water resources destruction in a certain range. In addition, the destruction of water resources by some mining industries can not be ignored, such as every coal mining. ......

How to protect water resources

Water is the source and foundation of life, and human health comes from water first. 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! In other words, water is the life of 2 billion people. In the world, 50 million children die every year because of drinking unclean water! How shocking this figure is! The water crisis has sounded the alarm for mankind! Saving water and protecting water resources are the top priority now!

How important water is to us! If everyone pays attention to saving water, I wonder how many people will benefit from it; On the contrary, if everyone wastes water resources carelessly, many people may suffer from drinking water difficulties! For example, some water pipes in public places leak, we can find someone to repair them, but if they are not repaired in time, it will be a waste of our drinking water. However, spilled water will never come back, which is tantamount to wasting water resources. How wrong this is!

Some factories do not pay attention to the protection of water resources, and discharge industrial wastewater into rivers and lakes, causing pollution in many rivers and lakes. However, such a result has to be taken seriously. Fish and shrimp will die if they drink such water; If humans bathe with such water, they will get sick; If humans drink such water, it will be harmful to their health. Water ring devours the health of human beings and animals! Imagine that even if the employees in the factory earn a lot of money, the water is polluted and people have no clean water to drink. So how do they survive? What's the use of asking for such money at that time? How bad it is for others!

Some people have developed a bad habit, that is, they like to throw garbage into rivers, lakes or other inappropriate places at will for convenience. Imagine that if everyone throws garbage into rivers and lakes, a lot of water resources will be polluted; If everyone litters at will, when it rains, the rain will wash the garbage into rivers and lakes, thus polluting the water resources on which we depend. If a lot of water resources are polluted, how can we survive? I think this bad habit is a temporary convenience and a lifelong hazard, which must be eradicated!

Now, because many aspects are polluting water resources, and the pollution is getting more and more serious, human beings can drink less and less water. However, without water, human beings can't survive. This means that we should take active actions to save and protect water resources now. In order to save and protect water resources, I think everyone should put an end to the bad habit of littering casually and throw garbage into the trash can; The uncles and aunts of the factory must resolutely prevent industrial wastewater from flowing into rivers and lakes, and must be treated harmlessly before being discharged; If the water pipe at home leaks, find someone to repair it immediately; To form a good habit of saving water, don't waste water resources casually (such as playing with water guns, washing vegetables and clothes can be used to flush toilets, etc.). ).

Let's join hands to save water and protect water resources! I believe that through the efforts of all of us, we will be able to do it!

What should we do to protect water resources?

What should we do in the face of this severe water resources situation: 1. We should have the consciousness of cherishing water. Only when we realize that "saving water is glorious and wasting water is shameful" can we pay attention to saving water all the time. 2, form good habits, 3, use water-saving appliances, 4, check the leakage and plug flow. As far as production is concerned, especially for some industries with large water consumption, we should focus on how to optimize the implementation of water system, how to improve the concentration multiple of reclaimed water, how to improve the recycling rate of water resources, and actively organize technical research to improve the comprehensive utilization rate of water; At the same time, a feasible operation system is formulated to manage the water consumption of products in quota, which is used as a technical and economic index for assessment to reduce waste. In the final analysis, human protection of the environment is based on the protection of the increasingly depleted resources on the earth, and the protection of water resources is the most basic condition for human survival and development. Below, the author talks about some superficial understanding on how to protect water resources in modern production and life. One way: explore new water sources. Another way is to reduce the demand for water. 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.

As a middle school student, how to protect water resources?

First, reduce industrial water consumption and improve water reuse rate.

Popularizing water-saving technologies, processes and equipment in key industries, relying on scientific and technological progress, accelerating the development of water-saving equipment and appliances, and improving production processes and technologies are important ways to save water and improve water utilization.

Establish industrial water-saving incentive mechanism to promote water saving. According to the conditions of water resources and the direction of industrial development, support or restraint policies should be adopted for different industries, water price standards should be formulated reasonably, industrial structure should be adjusted, and industrial enterprises should be encouraged and supported to carry out water-saving transformation and sewage reuse through financial subsidies and tax incentives.

Second, rationally arrange agricultural water use.

According to the different water requirements of different crops, various crops are optimized to achieve the best yield and water consumption, thus improving the benefit of irrigation water, vigorously popularizing the application of optimization technology and computer in irrigation water management, and improving the scientific nature of water management.

Three, recycling urban sewage, and actively promote the use of water-saving appliances.

Recycling domestic sewage to make it available is another effective method to improve the utilization rate of water resources. At present, urban public water, such as flushing toilets, spraying roads, environmental sanitation and municipal engineering, accounts for a considerable proportion, and most of them use tap water. If the domestic sewage reaches the standard after being treated by the sewage treatment plant, it will be widely used in urban greening, road cleaning, car washing, toilet flushing for residents, cooling water for enterprise equipment, etc. through the reclaimed water pipe network, the water utilization rate will be greatly improved.

Actively promoting water-saving appliances is an important means to save water and reduce waste. According to relevant media reports, from the end of 2006, Shanghai began to vigorously promote the application of water-saving appliances in bathroom. According to the statistics of relevant departments, by the end of 2006, Shanghai had renovated "water toilets" 1 1.8 million sets, saving about 1.7 million cubic meters of water annually. As of May, 2007, there are still 480,000 sets of similar toilets waiting for renovation in Shanghai. Upon completion, the city will save at least 8 million cubic meters of water, which is close to the city's daily water consumption, which is equivalent to building a medium-sized waterworks for Shanghai. With the development of the city and the increase of population, the promotion and transformation of water-saving appliances should be one of the key tasks of relevant departments.

Fourth, improve the laws and policies to protect water resources.

Establishing a sound water resources law and policy, strengthening the unified management of water resources and improving the law enforcement and supervision mechanism are the necessary prerequisites to ensure the sustainable utilization of water resources and the sustainable development of economy and society. Therefore, a series of water laws and regulations should be established, so that there are laws to follow, laws to be followed, law enforcement to be strict, and violators to be prosecuted.

If you don't cherish it, the last drop of water is equivalent to blood (the cry of nature's grief and indignation)

The vicissitudes of the old man, facing the turbid and smelly Sushui River, was both sad and angry. As a tributary of Fenhe River, Sushui River was originally very clear. Without it, there would be no prosperity of Yuncheng in Shanxi today. But now, the Sushui River is shameful-the silent old man is not only carrying a gourd ladle of sewage, but also calling for help from the Sushui River.

Naive children pointed to the sewage secretly discharged from the culvert and told adults that because of it, well water can't be drunk, and washing your hair will lose your hair. The child is bald. Not the green leaves that are about to drip, not the fruitful fruits, but thousands of colorful plastic bags fluttering in the wind. It seems so smug that what makes them proud is human misdeeds.

A pool of hard fish, a stream of sewage poured in, leaving only a sigh from the keeper and a pool of dead fish.

Smoky factories, villages buried in dust, creatures in the sky and underground transferred by human beings ... "Song of Life-Large-scale Photography Exhibition of Environmental Warning Education in China" opened today in China Revolutionary Military Museum. As the spokesman of the riddled nature, more than 65,438+000 shocking photos are shouting at human beings.

The photo exhibition is a panoramic review of China Environmental Protection Century Tour 10 years later. Most of the photos are from the works of journalists from China Environmental Protection Century Bank in recent years. In the past 3650 days and nights, hundreds of journalists have gone through hardships. With their professional sensitivity and strong sense of responsibility, they faithfully recorded the history of ecological environment changes in China with their own lenses and pens.

A touching photo warns us that the earth, the home of human beings, has been destroyed by human beings themselves. Wake up! Those stubborn saboteurs

The exhibition is divided into Huaihe River Shouting, Yellow River Ballad, Yangtze River Chanting, Green Variations, Andante Blue, Golden Ensemble, Hope and so on.

Walking towards the mother river, I saw the pond cracked and the land dried up: the water used along the Yellow River has exceeded the carrying capacity of the Yellow River, and the water shortage is serious. From 1972 to 1998, the lower reaches of the Yellow River stopped at 2 1, and the siltation in the main channel intensified. The "hanging river on the ground" in the lower reaches of the Yellow River is becoming more and more dangerous.

Walking towards the mother river, I saw black water surging into the main artery of the mother river. In recent years, the polluting enterprises in the Yellow River basin have developed rapidly during the Tenth Five-Year Plan, and the amount of sewage discharged into the main and tributaries of the Yellow River reaches 4.2 billion cubic meters every year. Sewage is getting more and more serious, and only sewage is flowing in many river sections.

The Yangtze River is also a sad song. An endless yellow sand is crying: the green at the source of the Yangtze River is shrinking. According to statistics, grassland degradation in the source area of the Yangtze River has reached more than 25,000 square kilometers. Due to the influence of rodents, 10% has become a secondary bare land of "black soil beach" type. Human activities have also aggravated the degradation of grassland. According to satellite remote sensing, the grassland area in Qinghai Province is deteriorating at a rate of 2 million mu per year, while the grassland carrying capacity in Qinghai Province is increasing at a rate of 3% per year.

Many tourists are stunned by this photo: the heads of countless Tibetan antelopes are piled together!

Tibetan antelope, known as the "plateau elf", lives on the "roof of the world"-no man's land in Hoh Xil, Qinghai-Tibet Plateau, and is a national first-class protected animal. Fifty years ago, there were nearly a million Tibetan antelopes living in Hoh Xil. When people discovered its amazing economic value (in the international market, the price of a cashmere shawl of a Tibetan antelope was 1. 1 000 dollars, and the highest price could even reach 40,000 dollars), for decades, the Tibetan antelope was on the verge of extinction, and now there are only 50,000 left. It is said that during the most rampant poaching period from 1990 to 1998, 20,000 Tibetan antelopes fell at the gunpoint of poachers every year. For the high profits of cashmere shawls, poachers are still desperate.

On Tianbao Mountain in Diqing, Yunnan, there is a mountainous area where many trees are cut down. Waist-high, black stumps stand quietly on the green grass like tombstones.

This used to be a well-preserved virgin forest. Although large-scale logging stopped at the end of last century, after more than 20 years of unscrupulous logging, how many virgin forests have been destroyed by Diqing, who can tell?

Seven major water systems, namely Haihe River, Liaohe River, Huaihe River, Yellow River, Songhua River, Yangtze River and Pearl River, are all polluted to varying degrees.

One third of the cities in China have air quality exceeding Grade III standard. Acid rain and sandstorms linger around us.

How to protect water resources?

Do not litter, vigorously publicize the protection of water resources, or engage in some beneficial activities related to the protection of water resources.

How to protect water resources

Water is the source and foundation of all things, and people cannot live without water for a moment. It is because of water that human beings will survive and everything in the world will be full of vitality, diversity and richness.

The water resources on the earth seem inexhaustible. In fact, according to the current situation of human use, only fresh water is the main water resource, and only a part of it can be used by people. Fresh water is a renewable resource, and its regeneration depends on the earth's water cycle. However, with the development of work and population growth, a large number of water resources are polluted. Some countries build dams in the upper reaches to extract river water, which changes the water flow and seriously affects water resources. Take China as an example! China ranks sixth in the world in terms of total water resources, but its per capita amount is a quarter of the world's, and it is also known as one of the thirteen water-deficient countries in the world.

At present, there are two kinds of water pollution: one is natural pollution and the other is man-made pollution. At present, man-made pollution is the most harmful to water resources. Water pollution is mainly caused by different impurities. More water, less water, dirty water, muddy water. For example, there is a lot of water in the Pearl River Delta, but it is not drinkable, and there are not many in the Huaihe River Basin in China. In a water network area of Shanghai, the length of the river is one square kilometer.

Do you know that?/You know what? Do you know that?/You know what? Among the 666 cities in China, there are 444 cities with insufficient water supply, and there are11cities with severe water shortage. Not only that, the daily water shortage alone reaches 6 million cubic meters. Take Guangdong Province as an example! At present, hundreds of thousands of people and tens of millions of livestock in rural areas have difficulty drinking water, and one third of people in cities have unclean drinking water. If we can establish the consciousness of saving water and turn off the tap at hand, a family can save hundreds of tons of water a year, and I believe this precious wealth will come back.

Therefore, as citizens, we should actively participate in the action of cherishing and protecting water resources and save every drop of water in our lives. Once people realize the importance of water resources, it is a problem, people! Wake up! Don't let tears become the last drop of water on our earth!

How to protect water resources in daily life

Have the consciousness of cherishing water. For a long time, people generally believe that water is inexhaustible. They don't know how to cherish, and some even waste it in vain. We should know that China's per capita water resources are not rich, and the regional distribution is uneven, with great inter-annual differences and unpredictable changes during the year. Coupled with pollution, water resources are in short supply, and tap water is more difficult to obtain. Cherishing water is the basis of saving water. Only when we realize that "saving water is glorious and wasting water is shameful" can we pay attention to saving water all the time.

2. Develop good habits. According to analysis, families can save about 70% water as long as they pay attention to getting rid of bad habits. There are many habits related to wasting water, such as: flushing cigarette butts and breaking garbage with the toilet; In order to get a cup of hot water, a lot of cold water was put in vain; Wash potatoes and carrots before peeling, or wash them before choosing vegetables; Intermittent use of water (when opening the door to pick up guests, answering the phone, changing TV channels), with the faucet on; Forgot to turn off the faucet during the water stop; When washing hands, washing face and brushing teeth, let the water flow all the time; Do not check the faucet before going to bed or going out; The equipment leaked and was not repaired in time.

3, the use of water-saving appliances, family water saving in addition to pay attention to develop good water habits, the use of water-saving appliances is very important, but also the most effective. In order to save money, many people would rather let themselves go than replace water-saving appliances. In fact, it is even more uneconomical to pay so much water fee in the long run. Using water-saving appliances can not only save money, but also protect the environment. Isn't it killing two birds with one stone? There are many kinds of water-saving appliances, including water-saving water tanks, water-saving faucets and water-saving toilets. Just use a few, and make a lot of contributions to water saving! 4, check the leak and plug the flow, the "drip into the river" at home is not a joke. Always check the tap water pipes in your home. In order to prevent a slight delay, don't ignore the leakage of faucet and water pipe connector. If you find water leakage, please ask someone or yourself to repair it in time to block the running water. For the water leakage that cannot be repaired for a while, it is best to temporarily control the water flow with the main switch. Take good care of the faucet and unscrew the water gate of the faucet by half, then the leakage flow will naturally be small, and the water loss will be reduced by half at the same time.

As far as production is concerned, especially for some industries with large water consumption, we should focus on how to optimize the implementation of water system, how to improve the concentration multiple of reclaimed water and how to improve the recycling rate of water resources, and actively organize technical research to improve the comprehensive utilization rate of water; At the same time, a feasible operation system is formulated to manage the water consumption of products in quota, which is used as a technical and economic index for assessment to reduce waste.

For a long time, most people have the idea of saving water, but there is no concrete action, and extravagance and waste are still common. Some people think that the great cause of the family, coupled with the Yangtze River, always thinks that this source is inexhaustible and lacks the sense of urgency and urgency to save water. If water is more expensive than oil, it will be too late for us to save water.
