Water resources are getting less and less

Bell..., the bell rang, and the students left the classroom one after another, preparing to eat. At this time, I found a classmate who was making soap, and the water pipe in front of him was flowing with water, as if to remind him, don't turn on the faucet but don't use water, you don't think about how much water it will waste. But the classmate was indifferent. I quickly went up and turned off the faucet, but he said, "Why did you turn it off? I still need to use it." I said, "You can just turn it on when you use it. Why do you have to waste this water?" He was helpless. Enough to say.

Yes, although one person cannot waste much water, but if everyone in the school or even in Beijing wastes such a small amount of water, then in one year, the water will be enough to form a big river. In order to make the data more accurate, let's do some calculations. Assume that the water flows at the same rate as when we wash our hands, 75 milliliters of water per second. There are 10 million people in Beijing, and each person washes their hands three times a day. Each person loses water for 60 seconds each time they wash their hands. In this way, it can be easily calculated that if all the people in Beijing use water without restraint every day, then everyone in Beijing will waste 49275000000 liters of water every year just by washing their hands, which is 49275000 tons of water, not to mention the water wasted by industry and agriculture. . From this data, it is easy to understand why Beijing’s groundwater is being pumped so quickly. Moreover, these water resources are enough for some small and medium-sized cities that are short of water for a year.

Although the south-to-north water diversion is currently underway, how many years will this water be enough to be used if it is wasted like this? Even if you don’t think about the people in water-scarce areas, you should think about your own future generations. Although there is still a lot of water on the earth, due to human destruction, water resources are no longer renewable and are gradually decreasing. If we don't take action immediately and everyone contributes to environmental protection, our earth will be destroyed sooner or later.

I really hope that the earth’s water resources will become more and more abundant instead of less and less.

Goal, score! !

Environmental protection means that humans consciously protect natural resources and make reasonable use of them to prevent the natural environment from being polluted and damaged; the polluted and damaged environment must be comprehensively managed to create a suitable environment. to the environment in which humans live and work. Environmental protection refers to the general term for various actions taken by humans to solve actual or potential environmental problems, coordinate the relationship between humans and the environment, and ensure the sustainable development of the economy and society. The methods and means include engineering technology, administrative management, legal, economic, publicity and education, etc. Its contents mainly include:

(1) Prevention and control of environmental pollution caused by production and living activities, including the prevention and control of the "three wastes" (waste water, waste gas, waste residue), dust, radioactive substances and generated emissions from industrial production. Noise, vibration, odor and electromagnetic microwave radiation, harmful gases, liquids and noise generated by transportation activities, pollutants discharged from maritime ship transportation, toxic and harmful chemicals used in industrial and agricultural production and people's daily life, smoke and sewage discharged from urban life and pollution caused by garbage;

(2) Prevent environmental damage caused by construction and development activities, including preventing environmental damage caused by large water conservancy projects, railways, highway trunk lines, large ports, terminals, airports and large industrial projects, etc. The pollution and damage to the environment caused by engineering construction, the damage and impact on the environment caused by agricultural reclamation and lake reclamation activities, the development of offshore oil fields, coastal zones and swamps, the development of forests and mineral resources, the establishment and construction of new industrial zones and new towns Damage, pollution and impact of construction on the environment;

(3) Protect the natural environment of special value, including rare species and their living environments, special natural development history relics, geological phenomena, and landforms etc. provide effective protection. In addition, urban and rural planning, controlling soil erosion and desertification, afforestation, controlling population growth and distribution, rational allocation of productivity, etc. are also included in environmental protection. Environmental protection has become one of the common actions and main tasks of governments and people around the world today. Our country has declared environmental protection as a basic national policy of our country, and has formulated and promulgated a series of environmental protection laws and regulations to ensure the implementation of this basic national policy.

my country’s ecological environment damage situation

1. Species extinction. my country is one of the countries with the richest biodiversity in the world. Higher plant and wild animal species account for about 10% of the world's total, and there are about 200 endemic genera in the country. However, environmental pollution and ecological destruction have led to the destruction of animal and plant habitats, a sharp reduction in the number of species, and some species have become extinct. According to statistics, about 4,600 species of higher plants in my country are endangered or threatened, accounting for more than 15% of higher plants. In the past 50 years, about 200 species of higher plants have become extinct, with an average of 4 species extinct every year; about 400 species of wild animals are in Endangered or threatened status, in recent years, illegal hunting, management, reselling, and consumption of wild animals have been repeatedly prohibited. Cases such as the illegal sale of rhino horns in Wuchuan County, Guangdong Province and the bile harvesting of live bears in Zhuhai have had a negative impact internationally.

2. Vegetation destruction. Forests are an important backbone of ecosystems. A healthy ecosystem requires forest coverage of only 13.9%. Although large-scale afforestation activities have been carried out since the founding of the People's Republic of China, forest destruction is still serious. In particular, the stock of mature forests and over-mature forests available for harvesting in timber forests has been significantly reduced.

At the same time, a large amount of forest land has been encroached upon, with the national annual average reaching 8.37 million acres from 1984 to 1991, showing an increasing trend year by year, which has largely offset the effectiveness of afforestation. Grassland is facing severe degradation, desertification and alkalization, which has intensified soil erosion and sandstorm hazards in grassland.

3. Land degradation. my country is a country with more serious land desertification in the world. Land desertification has developed rapidly in the past decade. The average annual desertification area was 1,560 square kilometers in the 1950s and 1970s. The average annual desertification area expanded to 2,100 square kilometers in the 1970s and 1980s, and the total area has reached 20.1 square kilometers. kilometer. Over the past 40 years, more than 500,000 square kilometers have been initially controlled, and the current soil erosion area has reached 1.79 million square kilometers. The problem of farmland degradation in my country is also very prominent. For example, in the Beidahuang area where the land was originally fertile, the organic matter of the soil has dropped from the original 5% to 8% to 1% to 2% (the ideal value should be no less than 3%). At the same time, due to imbalances in the agricultural ecosystem, approximately 2 million acres of cultivated land are destroyed by disasters across the country every year.

The same blue sky, the same fertile soil

The happiness of the sky is that it is dressed in blue; the happiness of the sun is that it has a dazzling brilliance like crystal; the happiness of the earth is It breeds colorful life...and my happiness is collecting the light spots of friendship around me.

Time flies, and my footsteps are about to pass the wonderful childhood. In the passing time, I bathed in the rain and dew of love, enjoyed the tenderness of love, which allowed me to grow up happily between heaven and earth, making my childhood life wonderful and colorful. All this comes from the fact that I live in a country of love and a life full of love. A society of family affection.

At 4 a.m. on December 31 last year, a rare double disaster of sandstorm and blizzard swept through the Xilingol League of Inner Mongolia. This snowstorm caused a severe shortage of forage in the affected areas of Inner Mongolia. In just two months, more than 650,000 livestock were killed or injured. At this critical moment, it was the people of the whole country who extended a helping hand, transporting nearly 800 million kilograms of feed to the disaster areas and investing 1.091 billion yuan in disaster relief funds. October 30, 1999 marked the 10th anniversary of the implementation of Project Hope. Through the efforts of the government and local people, 7,549 Hope primary schools were built with assistance, allowing more than 2.29 million out-of-school children to return to school.

The same blue sky, the same fertile soil. We learned about friendship through our eyes and ears. Although these are so ordinary in life, it is these countless ordinary things that have created our deep friendship with each other. It is fate that brings us all together to bathe in the warmth of the sun, share the sweet rain and dew, and taste the mellow flower season together, but we have also braved the wind and rain to survive difficulties and setbacks together. Although there are beautiful memories and sad memories in my life of more than ten years, no matter what, I am haunted by it: during the summer camp, there were our voices comforting the sick classmates in front of their beds, and there were our voices in the cafeteria. Every word of politeness, and even the laughter when we helped each other in the picnic competition; at the sports meeting, everyone shouted and cheered loudly. Beside the 100-meter track, those who passed around were a few bottles of inconspicuous mineral water, a few yuan A wet handkerchief also conveys selfless friendship. Not only that, every time we compete, we will hear the sincere wishes of "I wish you success." Every time we shed tears, we will also hear "Don't cry, laugh." The honest relief of a smile, it’s all too numerous to mention. As the saying goes: "Ten thousand taels of gold are easy to get, but it's hard to find a confidant!" When we have so many confidants and feel sincere love, aren't we gaining endless wealth?

The same blue sky, the same fertile soil, we are the same flowers blooming on the earth, and we are the same flying eagles fighting in the sky. Let us love and help each other, use sincerity to water the flowers of friendship, and use love to help every friend around us who is temporarily suffering - this is our true happiness.

When I was young, I heard my grandfather tell a story like this: Once upon a time, there was a villa where the forest was lush, the river was clear, the birds were singing and the flowers were fragrant, and people lived very happily. Later, a man came here and said to the local people: "You have great wealth." People were very happy, thinking that there was a lot of gold and silver buried here. So they started cutting down trees in search of gold. A year later, the man came again, and people questioned him because they had not found the treasure. The man sighed and said, "The wealth I'm talking about is the beautiful and pleasant environment you originally had." People were very sad after hearing this, because the climate here is now very bad, and few birds visit.

At that time, I did not understand this story. I don't think it's wrong for the villagers to destroy the paradise-like environment. Instead, I blame the outsiders for inducing people's thoughts. Thinking about it now, the villagers were really wrong. Beautiful nature is infinite wealth, which everyone can realize. Outsiders are just reminding the villagers to cherish it.

Camels walking across the desert, geese lining the sky, fish swimming in the shallows, and flowers blooming, these are the harmonious beauty of nature. Things develop according to certain laws, whether they rise or fall, they are beautiful. Even if it is like an epiphyllum, it is so amazing when it blooms, but it is also so vigorous and admirable when it withers. The beauty of nature itself may be a kind of infinitely charming beauty!

"The Great Wall of the Yangtze River, Huangshan and Yellow Rivers weigh a thousand pounds in my heart..." The song "My Chinese Heart" has touched the hearts of many Chinese people. However, due to people's deforestation, the beautiful Yangtze River and Yellow River have become yellow and dirty, and even stopped flowing.

Human beings are the leaders of nature. They can make nature more harmonious and unified, or they can destroy nature. In recent years, in order to seek more economic benefits, people have caused serious damage to nature, making many precious flowers and rare animals on the verge of extinction. Fortunately, people now realize that the ecological value of nature far outweighs its economic value, and various nature reserves have been established. However, people paid a huge price for this. If people respect nature, they can save more money and invest in scientific research.

Nature is the home on which we depend for survival. By attacking and destroying it we are pushing ourselves into a pit of fire. In order for us to survive and develop better, we should cherish it and protect it.

Natural beauty, sacred beauty, let us protect it together!

Let natural beauty become holy and eternal!

I want to open my arms,

fly to the sky.

I want to sing loudly,

Better tomorrow.

Tomorrow is a new century.

Tomorrow is a new vision.

Tomorrow is the yearning of hundreds of millions of people.

I want to work hard and make progress.

Defend the motherland.

I want to gaze with my heart,

Green home.

Home, our home.

Home is the hope of hundreds of millions of people.

We only have one home,

We should cherish it.

p>

Green home,

The origin of our life.

Green home,

Our health protection.

Protection Environment,

Start with me,

Let us work together to protect nature,

Together we can protect our home

——Earth

The earth is the home of all things and is the true mother of mankind. In the past, the earth had a clear blue sky, green mountains, and clear rivers. It was truly beautiful, spectacular, and amiable. But what about the earth now? The sky is no longer as blue as it was yesterday, the mountains are no longer as green as they used to be, and the rivers are no longer as clear as they used to be. Compared with the previous earth, earth-shaking changes have undoubtedly taken place.

A little canary said sadly: "Not long after I learned to fly, my green home was destroyed, and my parents had to take me away from home. In the process of escaping, we still couldn't avoid this cruelty. The reality - my father was killed by a ruthless hunter, and my mother left this world to protect me. At the same time, I had to continue looking for a new home alone. "Uncle Dadi?" asked with concern. The little canary wiped her tears and said, "No way. All I found were hot deserts, bare forests, and turbid rivers... The world is so big, but I can't find a place where I can live and work in peace and contentment." Xiao Jin The canary was so thirsty that it came to a small river and was about to drink water, but Uncle Dad stopped him: "You can't drink that water! It's poisonous!" The little canary couldn't bear it any longer, and said: "I If you don't drink, you will die of thirst. Anyway, you will die horizontally and vertically, so it's better to die happily!" After saying that, it started to drink water, and as soon as it took a sip, the little canary said, "Ah!" Then he died.

Are there too many tragedies like Little Canary? We have only one earth, and it is the only home for mankind. Human beings, take action and protect the ecological environment! Otherwise, the consequences would be really unimaginable! It’s not too late to “make things right”, the earth can still be saved! Let us live together on this earth, enjoy the blue sky together, and enjoy the warmth of sunshine, rain and dew together!

The alarm bell has sounded, it’s time for mankind to wake up!

The Earth does not need heavy makeup. I don’t know since when, it has become more and more beautiful. Its sapphire-like skin color makes it the most beautiful planet in the solar system. She kept turning, and everything around her kept changing. And she doesn’t know when a group of makeup artists—human beings—appeared around her. At first, human beings only decorated the earth with some houses sporadically, and took care of the hair that had not been taken care of for many years, making the earth look more beautiful and energetic. Makeup artists think it is inappropriate to dress up the earth in this way. The earth is still the same as before, and it has not achieved a refreshing effect. So, they began to carry out large-scale cosmetic operations on the earth. First of all, the object of makeup artists' treatment is still the earth's "luxurious" hair. They believe that too much hair will affect the visual effect, and the earth's hair is a good building material, so they came up with a way to kill two birds with one stone, that is, give the earth a haircut. The more broken the better, it is possible to cut out a hair. A hairstyle that is extremely broken - "Three Hairs". If those three hairs are accidentally removed, it may become "Zhuo Zhuo Tongshan". Therefore, makeup artists don't know whether it is possible for the earth to be bald by them. When they were interviewed by reporters, they said: "Our purpose is to make her hairstyle more avant-garde. How can we give her a bald head?" In order to obtain a large amount of wood and to make the earth's hairstyle more avant-garde, they immediately broke ground. As everyone knows, if their plans continue to develop, it will become inevitable for the earth to become a big bald head.

So, they invited a lot of loggers and porters to move all the felled trees to the place they had planned for the big house building operation. As buildings rise from the ground, the earth does become more and more beautiful, hairstyles become more and more avant-garde, and makeup artists feel more and more great about themselves. They consider their bold design a success. So they let lumberjacks carry out predatory development and architects build like crazy. The earth, which used to live a leisurely and comfortable life, no longer feels that its life is easy. The roar of machines day and night makes the earth feel upset, and the dust flying during construction makes the earth breathless. As a result, the earth began to grieve and shed tears, and tears flooded many cities. But the makeup artists don't pay attention to this, they just keep doing their job. Not only do they have to cut Earth's hair and make clothes, but they also have to "paint her". The originally blue and clear face became cloudy and rough due to their makeup. Not only that, they also put a thick layer of oil paint on her. The earth has not become more beautiful because of their dressing up. On the contrary, it has lost its previous purity. She couldn't stand it anymore, she started to get angry, she screamed, she cried. When the makeup artists were rushed far away by the tears of the earth, they realized that the makeup they gave to the earth was too thick, so thick that the earth almost stopped breathing. They realize that they are not beautifying the Earth, but torturing it, and that they are not making the Earth glow any more charmingly with their presence. So, they began to remove the makeup from the earth. Fortunately, it was not too late for them to wake up. The earth after the makeup was removed was full of vitality and relaxed. The luxury is gone and the truth is revealed, and the earth turns leisurely and leisurely as before.

What are humans?

Under a huge photo of dinosaurs is written the following sentence: "There are many giant beasts that cannot adapt to changes that have disappeared from the earth." That What about people? What are people? Are they giants compared to ants, or are they tiny ants at the feet of dinosaurs? Are they what we call advanced animals, or are they a group of fools who actually know nothing? Are they the owners of our lovely earth, or are they a bunch of pitiful people? Slaves of nature? Oh, what on earth are humans!

Ever since humans emerged on the earth, they have been nondescript. It is said to be a monkey, but it cannot jump between branches. It is said to be an ape. Its arms are a bit short, and it does not like to make graceful movements of beating its chest.

This thing is inherently destructive. It creates fire that can destroy everything with ulterior motives, just like it creates atomic bombs today. It tries every means to attack other innocent animals and leisurely shuttles through various nutritional chains of the food chain - eating anything as long as it is edible. And this ability is getting better and better from generation to generation. Nowadays, except for rats, all the animals in the world are almost becoming rare animals. They still protect them all day long. Why don’t we just stop! It’s shameless to say that other people’s animals cannot adapt.” Variety". It is asking endlessly from nature, asking her lush green to turn into black charcoal for cooking delicious food, asking her beautiful rivers to turn into carriers of sewage, and asking her blue sky to turn into rags full of holes. , turning her originally moist and flat ground into a trap-like funnel. They were even digging into the hard earth day by day, trying to extract every element from her body - as long as they lived comfortably. As long as they live comfortably, humans are willing to do anything. They use the tools invented by their ancestors to shave off pieces of the earth's head. In some places, pus is leaking and black smoke is emitting! The earth is groaning, I'm shouting, will the next behemoth disappear be the earth itself? Because she can't adapt to crazy humans! It is said that people don't care about this - they still want to live on Mars, the sun, etc.! Look! Come on, humans will not stop until they turn the universe into powder!

What are humans? I still don’t understand.

Comment: Lu Xun said: "Laughter, anger and curses all become articles." Saying "what are people" is almost a curse. But sometimes, that indifferent criticism is really not as good as a scolding that makes people happy to listen and makes people wake up easily. The author ruthlessly exposed and bitterly ridiculed the bad behavior of human beings that destroy nature and ecology out of their selfish instincts. He calls nature "her" and calls humans "it". He repeatedly emphasizes that he doesn't know what humans are and calls them nondescript. His dissatisfaction and resentment towards human behavior are palpable. Compared with various related texts of warnings, rules and even prayers, the article shows a fierce and sharp fighting style and a serious and cold personality behind the humor, which leaves a deep impression on people.

Development and Environmental Protection

Countries in the world must increase their efforts to develop their own economies if they want to establish their prestige internationally. In industrial production, people seem to ignore environmental protection and only want to benefit from economic interests. Don’t think that you haven’t suffered any losses. If you receive a benefit in the economy, you will also suffer a loss in terms of environmental protection. Over time, it is you who suffers in the end.

After the founding of the People's Republic of China, China's industry has developed rapidly, its economic value has improved a lot year by year, and its international status has slowly risen. However, the degree of environmental damage has also become greater and greater. Therefore, if we want to develop rapidly while also being environmentally friendly, we have to take the path of sustainable development.

Since we are going to take the path of sustainable development, we must proceed in an orderly manner.

We cannot develop first and treat later. We must focus on "prevention", combine prevention and control, and implement comprehensive management; whoever develops will protect it, and whoever pollutes it will treat it. It is impossible to achieve the expected goals by relying on individuals alone. We must also rely on the power of the masses to protect the environment.

Let us work together to create our beautiful life!
