The importance of water resources, the importance of water resources to us

The price of water is going to rise, which shows that water resources are very important.

Water is the source of human life, water accounts for 70% of the total weight of the human body, and the life of plants and animals is inseparable from water, water is the basic unit of life.

It is the basic condition for the development and reproduction of life. Water is also an important component of the atmosphere, and it regulates the climate by evaporating and then forming rainfall.

The importance of water to us.

Water resources are water sources that are available or likely to be used, with 72% of the Earth's surface covered by water, but freshwater resources.

It accounts for only all water resources.

Natural water resources include river runoff, groundwater, snow and glaciers, lake water, swamp water, and seawater. According to the water quality, it can be divided into light pants front water and salt water.

1. Water conservancy and irrigation: Since ancient times, there has been little rain in the northwest and there is often a bitter drought. People have passed the drought season by bringing water from rivers to irrigate their fields.

2. Hydraulic transportation: Sorting out the transportation has a long history, people use the fluidity and carrying capacity of water, driving cargo ships on the water to transport Huaiyu materials, and sea transportation provides a new way for transportation. 3. Seawater desalination

Although most of the earth is covered by water, it is a freshwater resource.

Scarce. Modern technology is used to separate the salt water in the seawater and desalinate the seawater.

In this way, the problem of scarcity of freshwater lead blind rock resources can be solved to a large extent. 4. Hydroelectric power: through the water level difference, the potential energy contained in the water body is used to alleviate the current problem of insufficient power to a large extent.

5. Build dams: intercept the flow of water from rivers and channels for power generation, irrigation, etc.

1。Human survival is inseparable from water;

2。There is now a shortage of water in many places;

3。Water pollution has become a big problem;

4。Therefore, we should actively invest funds in the construction of water resources, and at the same time, we should also take active measures to protect water resources.

5。It is proposed to build a grand canal running through the north and south, and build more reservoirs.

6。Heavy penalties are imposed for polluting water resources.

I am most concerned about the issue of water, and I wrote the above text, hoping that all people will pay attention to this issue!

Water plays a vital role in the development of human society. First of all, water sustains human life. Modern science has proved that each person needs to consume 2000ml of water per day to maintain life, and if you are dehydrated for 7 to 10 days, people will die, and if you lose 15% of water, 20% of people will have symptoms of dehydration.

Secondly, water plays an important role in human life and production processes. Human domestic water is divided into urban domestic water and rural domestic water, the former is mainly household water, but also includes public building water, fire water, watering green space and other municipal water. Affected by the nature of the city, economic level, climate, water source, water quantity, residents' water habits, charging methods, etc., the per capita water consumption of urban domestic water varies greatly, and the generally developed areas are higher than the underdeveloped areas, and the water-rich areas are higher than the water-scarce areas.

The world's urban domestic water accounts for about 7% of the world's water consumption, and China's urban water consumption accounts for the country's total water consumption. [1]

There are two types of water used in production: agricultural water and industrial water. Agricultural water mainly includes agricultural irrigation, animal husbandry irrigation and fishery water. Affected by climatic and geographical conditions, crop varieties, irrigation methods and technologies, management level, soil, water sources and engineering facilities, there are great changes in the spatial and temporal distribution of agricultural water consumption.

Industrial water mainly includes raw materials, cooling, washing, transportation, temperature and humidity regulation, etc., and industrial water consumption is closely related to various factors such as industrial development layout, industrial structure, and production technology level. The world's industrial water consumption accounts for about 22% of the world's water consumption, and China's industrial water consumption accounts for a proportion. China's industrial water consumption is concentrated in thermal power generation, textile, papermaking, iron and steel, petroleum and petrochemical industries, and the water consumption of the five major industries accounts for the national industrial water consumption.

Thirdly, water also plays an important role in ecological and environmental protection. In areas with fragile ecological environment, ecological water must be met as a priority, otherwise it will lead to the deterioration of the ecological environment. Ecological water use is a broad concept, such as river water quality protection, soil and water conservation, water and heat balance, vegetation construction, maintenance of river water and sediment balance, maintenance of terrestrial water and salt balance, protection and maintenance of ecological base flow of river ecosystems, water required for recharge of over-exploited groundwater, and water use for urban green space.

According to the international standard, the utilization rate of river water resources should not exceed 40%, while the utilization rate of the Yellow River in China has reached more than 70%, and the utilization rate of Haihe River water resources is close to 90%. The over-utilization of river water resources has seriously crowded out ecological water, weakened the function of rivers to maintain ecological balance, and deteriorated the ecological environment of river basins. The functions of ecological water use also include maintaining the survival and reproduction of river species and diluting industrial, agricultural and domestic wastewater discharged from urban and rural areas.

From the perspective of the relationship between man and nature, the practice of squeezing out ecological water to develop the economy seriously violates the laws of nature and will be punished and retaliated against by nature.

There are several reasons why the protection of water resources is more important than the exploitation of water resources

1.Water resources are an important ecological treasure house, and protecting water resources is a basic requirement for maintaining the security of the regional ecological environment, and it is also an important part of promoting the high-quality social and economic development of the river basin.

2.There is uncertainty in the development of water resources, which may cause irreversible damage to water resources, and once damaged, it will seriously affect the ecological environment in the basin and the development of human society.

Therefore, in order to maintain the ecological balance and the sustainable development of human society, the protection of water resources is more important than development. In the case of limited water resources, we should try to protect them, but also develop them.

Hello, water is very precious, and when it runs out, it will be gone.

1. The importance of water to human beings.

Water is the source of life and one of the most indispensable and important material resources for human survival and development. On Earth, all life activities originated from water. The body is about 65% of body weight.

Without water, nutrients from food cannot be absorbed, waste products cannot be excreted from the body, and drugs cannot reach the site of action. Once the human body is dehydrated, the consequences are very serious.

2. The importance of water for agriculture.

As a reactive substance of metabolism, water plays a pivotal role in photosynthesis, respiration, and the synthesis and decomposition of organic substances. Water is the solvent used by crops for the absorption and transport of substances. Without water, crops cannot grow and develop, let alone produce food.

3. The importance of water to modern industry.

In modern industry, there is no industrial sector that does not require water, and there is no industry that is not related to water. More industries need to use water to cool equipment or products, such as steel mills. Water is also often used as a detergent, such as rinsing raw materials or products, cleaning equipment or floors, and every factory uses the various functions of water to maintain normal production, and almost every production link has water involved.

The importance of protecting water resources.

Water is the material basis for the existence of life on earth, and water resources are the primary condition for maintaining the sustainable development of the earth's ecological environment. So, what exactly can be done to protect water resources?

1. Change the traditional concept of water use.

It is important to recognize that water is precious, and that the amount of water used to flush the toilet bowl is equivalent to the daily water consumption per capita in some developing countries; Take a shower in the summer, using water equivalent to the daily consumption of dozens of people in a water-scarce country. This is by no means sensational, but the result of many years of investigation by the relevant United Nations bodies. Therefore, it is necessary to call for water conservation in the whole society, establish a sense of cherishing water, use one water for multiple purposes, and fully recycle water.

2. Rational development of water resources.

The development of water resources includes the development of surface water resources and the development of groundwater resources. When extracting groundwater, due to the large differences in the water quality of each aquifer, it should be extracted in layers; Mixed mining of contaminated diving and confined water shall not be allowed; For exploration projects that expose and penetrate aquifers, it is necessary to strictly do a good job of layered water stopping and sealing holes in accordance with relevant regulations, so as to effectively prevent water pollution and ensure the sustainable development of water bodies themselves.

3. Improve the utilization rate of water resources.

The key to effective water conservation lies in the rational use of water resources, strengthening management awareness, doing a good job in long-term planning, and scientifically giving play to the important role of water resources in social and economic development. In terms of domestic water, we should install effective water metering devices, carry out unified management, charge reasonable fees, and strengthen the awareness of water conservation among the whole people; In terms of water use in industry and agriculture, we will carry out multi-faceted water-saving projects and build reservoirs in accordance with local conditions.

4. Prevention and control of water pollution.

Water pollution includes surface water pollution and groundwater pollution, and industrial wastewater, industrial waste, industrial waste gas, domestic sewage and domestic garbage generated in the production process can all cause water pollution through different infiltration methods, and effective prevention and control of production and domestic sewage shall be carried out.

Water is the source of life, the foundation of life, and human health comes from water. A person can go days without food, but not for a few days without water. Water is the source of life.

The metabolism of all living things is inseparable from water, but water is not inexhaustible. Water, to be exact, freshwater, is needed by living beings. Water is about 70% of the Earth's area, but 97% of it is seawater, and only 2% of the rest is actually usable freshwater resources, excluding glaciers and saltwater lakes.

This water is needed to sustain thousands of creatures on our planet.

Water is an indispensable substance in the bodies of animals and plants and in human bodies, and it can be said that there is no life without water. In addition, water is inseparable from food, clothing, housing and transportation in human life. Water is also an important raw material for industrial and agricultural production.

The amount of fresh water consumed in agricultural production accounts for 60%-80% of the total amount of fresh water consumed by human beings, and a large amount of water is also used in industry for production. Water also plays an important role in inland and marine transport. In nature, less than 1% of the total amount of fresh water is available.

According to the 21st Century International Symposium on Urban Water Resources, the United Nations has listed China as one of the 13 most water-scarce countries in the world, and China's per capita water consumption is about 30% of the world's per capita water consumption. Humans are now using more and more water, and the pollution is getting worse, which requires us to protect water resources.

The importance of water resources to humans and to the spring system is manifold. Here are a few key aspects of the importance of water resources:

1.Life is sustained: Water is one of the basic elements of life.

For humans and other living beings, water is necessary to meet the needs of the body and sustain life-sustaining activities. We need water to drink, bathe, cook, and it's also an essential resource for growing crops and raising animals.

2.Food security: Water is one of the key elements of agriculture. Agriculture requires a lot of water to irrigate crops, maintain good soil moisture levels, and promote plant growth. Inadequate or uneven distribution of water resources can have serious implications for crop yields and food security.

3.Industry and energy production: Water plays an important role in industrial production and energy production.

Many industrial processes require water for cooling, cleaning, and manufacturing. Water is also a key component in many energy production processes, such as hydropower, nuclear power, and thermal power.

4.Ecological balance: Water is essential for maintaining the health and balance of ecosystems. Inadequate or polluted water resources can damage aquatic ecosystems such as wetlands, rivers, lakes and oceans, affecting plant and animal species and even leading to biodiversity loss.

5.Economic development: Water plays an important role in economic development.

The rational use and management of water resources is the basis for the development of agriculture, industry, tourism and other sectors of the economy. Water-rich regions are often better able to support economic growth and social stability. <>
