How to protect the water environment

Question 1: How do we protect water resources? First, start from the small things around you, save water in your life, and don't waste it indiscriminately.

Pay attention to environmental protection when traveling or passing through lakes and rivers with water sources, 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.

Question 2: What should we do to protect the environment? 1. No littering.

2. Don't spit everywhere

Don't chop and change.

4. Try to save stationery.

5. Try to avoid using disposable goods.

6. Don't kill wild animals at will.

7. Replace ordinary light bulbs with energy-saving lamps as much as possible.

8. Gardeners should apply organic fertilizers.

9. Slow down when driving.

10. Try to walk instead of riding a car or bike.

Question 3: How should we protect water resources? First of all, we should start from the small things around us, save water in our lives, and don't waste it wantonly. Second, pay attention to environmental protection when traveling or passing through lakes and rivers with water sources, and don't throw things into the water. Thirdly, we should advocate the conservation and recycling of water resources and always remind people around us to join the ranks of environmental protection.

Question 4: 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. Leakage and blockage. As far as production is concerned, especially for some industries with high water consumption, we should actively organize technical research to improve the comprehensive utilization rate of water around how to optimize the operation of water system, how to improve the concentration multiple of circulating water and how to improve the recycling utilization of water resources; 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. Water resources development includes surface water resources development and groundwater resources development. 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 coal mining every ... & gt

Question 5: 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.

Question 6: How to protect water resources There is a lot of water on the earth, but the fresh water reserves available for people to directly use only account for 2.53% of the total water in the world, of which 68.7% belong to solid glaciers, which are distributed in the mountains and poles that are difficult to use, and some fresh water is buried deep underground and difficult to exploit. At present, only groundwater, lake fresh water and river bed water can be directly utilized by human beings, and the sum of the three accounts for about 0.77% of the total water volume of the earth. In fact, the water available to human beings only accounts for about 0.26% of the total water of the earth. In addition, the amount of fresh water resources used by human beings is increasing. Therefore, the protection and utilization of fresh water resources has become a major concern of contemporary human beings.

As far as China is concerned, according to statistics, 20 million people in China have difficulty drinking water; More than 400 cities are seriously short of water. From the end of 2009 to 20 10, once-in-a-century droughts occurred in Yunnan, Guizhou, Guangxi, Chongqing, Sichuan and other places in China. It is predicted that there will be a water shortage peak in China in 2030.

In order to save limited fresh water resources, I explored a small water-saving method for toilets. I might as well try. The method is as follows: put two bottles of mineral water filled with water in the toilet tank (or put a large bottle and a small bottle, depending on the effect), so that each time the toilet is flushed, the two bottles of mineral water will not come out, but the urinal will be flushed clean. So you can save two bottles of water every time you flush the toilet. According to this calculation, if a family of three flushes 10 times a day, it can save 20 kilograms of water every day and (20×360)7200 kilograms of water a year, that is, 3.6 tons. Therefore, a city with a population of 6,543,800+0,000 will save (30× 3.6) 6,543,800+0,800 tons of water a year. At the same time, it can save more than 3 million yuan.

The principle is that the water tank volume of the toilet is fixed. Put a certain volume of mineral water bottle in the water tank, and the volume of water in the water tank includes the volume of mineral water bottle. When washing, the water in the mineral water bottle volume cannot flow out, and the washing effect depends on the washing pressure and water quantity. Under the condition of keeping the pressure constant, as long as there is enough water, the flushing effect should not be affected (I use a four-dimensional toilet at home, and put two bottles of water in it, and the flushing effect is still very good).

Of course, saving water resources is just a small way for me, for reference only, not enough! About13 of the world's population lives in areas with moderate and high water shortage, and the consumption of fresh water in these areas exceeds 10% of the total renewable water resources. 1972 The United Nations Conference on Human Environment pointed out: "After the oil crisis, the next crisis is water". 1977 The United Nations Water Conference further emphasized that "water will soon become a profound social crisis". Nowadays, the global situation of fresh water resources is not optimistic, water resources are short, water quality is deteriorating, and the crisis of fresh water resources seriously restricts sustainable development, and human beings are facing severe challenges.

To protect water resources, we must raise the awareness of all mankind, reach an international consensus, conclude a unified international convention, protect global water resources through global cooperation, and even more need a unified international water law. International water legislation should move towards codification and globalization, and use it to coordinate the actions of countries, guide countries to cooperate in the protection and utilization of global water resources, and at the same time assume corresponding international obligations and responsibilities. And establish, develop and improve regional freshwater protection mechanisms on all continents.

Facing the water crisis, only by strengthening water resources protection legislation and forming an effective water law system can China effectively deal with the problems it faces.

Please remember that we can't make water, we can only cherish it!

Question 7: 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 injury, and it must be carved from the roots!

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!

Question 8: How to protect water resources? Water is the source and foundation of all things. 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 have been 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!

Question 9: How to protect and cherish water resources in daily life? For a long time, people generally think that water is "inexhaustible", and some people even waste it without knowing how to cherish it. 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 and lack of water resources, tap water is even more difficult. 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 high water consumption, we should actively organize technical research to improve the comprehensive utilization rate of water around how to optimize the operation of water system, how to improve the concentration multiple of circulating water and how to improve the recycling utilization of water resources; 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.
