The bell rang, and the students left the classroom one after another, ready to eat. At this time, I found a classmate making soap, and the tap water pipe in front of him was running, as if to remind him not to turn on the tap but not to use water, and you don't want to think about how much water it would waste. But this classmate is indifferent. I quickly went up and turned off the tap. He said, "Why did you turn it off? I still need it. " I said, "Just open it when you use it. Why do you have to waste this water? " He has nothing to say.
Yes, although one person can't waste much water, if everyone in the whole school and even Beijing wastes such a little water, one year will be enough to merge into a big river. To make the data more accurate, let's calculate it. Suppose that according to the flow rate of water when we wash our hands, 75 ml of water flows every second. There are10 million people in Beijing who wash their hands three times a day, and each person loses water for 60 seconds each time. In this way, it is easy to calculate that if everyone in Beijing uses water without restraint every day, then everyone in Beijing will waste 492.75 million liters of water every year just by washing their hands, which is 49.275 million tons of water, not to mention the water wasted by industry and agriculture. From this data, it is easy to know why the groundwater in Beijing is pumped so fast. Moreover, these water resources are enough for some small and medium-sized cities that lack water for one year.
Although the South-to-North Water Diversion Project is being carried out now, how many years can the water be used if it is wasted? Even if you don't think about the people in the water-deficient areas, you should think about your future generations. Although there is still a lot of water on the earth, due to the destruction of human beings, water resources can no longer be regenerated and are gradually decreasing. If we don't act immediately and everyone contributes to the encirclement, then our planet will be destroyed sooner or later.
I really hope that there are more and more water resources on the earth, not less and less.
Goal! Goal! !
Environmental protection means that human beings consciously protect natural resources, make rational use of natural resources, and prevent the natural environment from being polluted and destroyed; It is necessary to comprehensively control the polluted and destroyed environment and create an environment suitable for human life and work. Environmental protection refers to various actions taken by human beings to solve real or potential environmental problems, coordinate the relationship between human beings and the environment, and ensure the sustainable development of economy and society. Its methods and means include engineering technology, administration, law, economy, publicity and education, etc. Its contents mainly include:
(1) Prevention and control of environmental pollution caused by production and living activities, including prevention and control of "three wastes" (waste water, waste gas and waste residue), dust, radioactive substances, noise, vibration, odor and electromagnetic microwave radiation, harmful gases, liquids and noise generated by transportation activities, pollutants discharged by ships at sea, toxic and harmful chemicals used in industrial and agricultural production and people's life, and smoke and dust discharged from urban life.
(2) Preventing environmental damage caused by construction and development activities, including preventing environmental pollution and damage caused by large-scale water conservancy projects, railways, highway trunk lines, large-scale ports and docks, airports and large-scale industrial projects, and preventing environmental damage, pollution and impact caused by land reclamation around lakes, development of offshore oil fields, coastal zones and swamps, development of forests and mineral resources, and establishment and construction of new industrial zones and new towns;
(3) Protecting the natural environment with special value, including effectively protecting rare species and their living environment, historical sites of special natural development, geological phenomena, landforms and landscapes, etc. In addition, urban and rural planning, controlling soil erosion and desertification, planting trees, controlling population growth and distribution, and rationally allocating productive forces also belong to environmental protection. Environmental protection has become one of the common actions and main tasks of governments and people all over the world. China declared environmental protection as a basic national policy, and formulated and promulgated a series of environmental protection laws and regulations to ensure the implementation of this basic national policy.
Ecological environment destruction in China.
First, species extinction. China is one of the countries with the richest biodiversity in the world. The species of higher plants and wild animals account for about 10% of the world, and there are about 200 endemic genera under basic protection. However, environmental pollution and biological destruction have led to the destruction of animal and plant habitats, the number of species has dropped sharply, and some species have become extinct. According to statistics, about 4600 species of higher plants are endangered or threatened in China, accounting for 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 endangered or threatened. In recent years, illegal hunting, trading, reselling and eating wild animals have been repeatedly prohibited. Cases such as illegal sale of rhinoceros horn in Wuchuan City, Guangdong Province, and taking gall from live bears in Zhuhai have caused bad influence internationally.
Second, vegetation destruction. Forest is an important pillar of ecosystem. A benign ecosystem only needs 13.9% forest coverage. Although large-scale afforestation activities have been carried out since the founding of the People's Republic of China, forest destruction is still very serious, especially the volume of mature forests and over-mature forests available for logging has been greatly reduced. At the same time, it occupies a lot of forest land, with an annual average of1984 ~199/kloc-0 of 8.37 million mu, showing an upward trend year by year, which largely offsets the effect of afforestation. Grassland is facing serious degradation, desertification and alkalization, which aggravates soil erosion and sandstorm hazards.
Third, land degradation. China is a country with serious land desertification in the world. In the past decade, land desertification has developed rapidly. In 1950s and 1970s, the average desertification area was 1.56 square kilometers, and it was expanded to 2 1 square kilometers in 1970s and 1980s, with a total area of 20. 1 square kilometers. Over the past 40 years, more than 500,000 square kilometers have been preliminarily treated, and the current soil erosion area has reached 6,543,800 square kilometers. The problem of farmland degradation in China is also very prominent. For example, in the fertile northern wilderness area, the soil organic matter decreased from 5% ~ 8% to 1% ~ 2% (the ideal value should not be lower than 3%). At the same time, due to the imbalance of agricultural ecosystem, about 2 million mu of cultivated land in China is damaged by disasters every year.
The same blue sky, the same fertile soil
The happiness of the sky lies in its blue clothes; The happiness of sunshine lies in its dazzling brilliance like crystal; The happiness of the earth lies in its rich and colorful life ..... and my happiness is to collect the light of friendship around me.
Time flies, my footsteps are about to go through a wonderful childhood. In the passing time, I bathed in the rain and dew of love and enjoyed the tenderness of love, which made me grow up happily between heaven and earth and made my childhood life wonderful. All this comes from living in a loving country and a loving society.
Just at 4: 00 a.m. on February 3 1 last year, a double disaster of sandstorm and blizzard, which is rare in history, swept through Xilin Gol League in Inner Mongolia. The snowstorm caused a 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 juncture, it is the people of the whole country who lend a helping hand, dispatching nearly 800 million Jin of feed to the disaster-stricken areas and investing 19. 1 100 million yuan in disaster relief funds. 65438 19991October 30th, the anniversary of the implementation of Project Hope10th. Through the efforts of the government and local people, 7,549 Hope primary schools were built, which enabled more than 2.29 million dropouts to return to school.
The same blue sky, the same fertile soil. We learned to be friendly by listening and watching. Although these things are so ordinary in life, it is these countless ordinary things that have created our deep friendship with each other. It is fate that makes us all bathe in the warmth of the sun, share the sweet rain and dew, and taste the mellow flower season together, but we have also spent difficulties and setbacks together. Although there are good memories and sour memories in my life for more than ten years, no matter which one makes me dream: in summer camp, there are comforting voices in front of our sick classmates, courtesy in the canteen, and laughter when helping each other in the picnic contest; At the sports meeting, everyone shouted and cheered loudly. Next to the 100-meter runway, a few bottles of humble mineral water and some wet handkerchiefs were sent, as well as selfless friendship. Not only that, we will hear the sincere wishes of "I wish you success" in every competition, and we will also hear the frank relief of "Don't cry, smile" every time we cry. As the saying goes, "Two thousand gold is easy to get, but a bosom friend is hard to find!" "We have so many intimate friends and feel sincere love, haven't we gained endless wealth?
The same blue sky, the same fertile soil, we are both blooming flowers on the earth and eagles fighting the sky in the blue sky. Let's love and help each other, water the flowers of friendship with sincerity, and help every friend who is temporarily suffering with love-this is our real happiness.
When I was a child, I heard a story from my grandfather: a long time ago, there was a mountain 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 are very happy and think that there are a lot of gold and silver treasures buried here. So they began to cut down trees in search of gold. A year later, the man came again and people questioned him because he didn't find the treasure. The man sighed and said, "The wealth I'm talking about is the beautiful and pleasant environment you once had." People are very sad after hearing this, because the climate here is very bad now, and there are few birds visiting.
At that time, I didn't understand the story. I don't think it is wrong for villagers to destroy the rural environment, but to blame outsiders for inducing people's thoughts. Now that I think about it, the villagers are really wrong. Beautiful nature is infinite wealth, and everyone can feel it. Outsiders just remind villagers to cherish it.
Camels walk in the desert, geese line up in the sky, fish swim shallowly and flowers bloom, all of which are the harmonious beauty of nature. Things develop according to certain laws, whether they are prosperous or declining, they are all beautiful. Even if it is like epiphyllum, it is so amazing when it opens and so vigorous and admirable when it withers. The beauty of nature itself may be a charming beauty!
"The Great Wall of the Yangtze River and the Yellow River in Huangshan are heavy in my heart ..." A song "My China Heart" touched the hearts of many people in China. However, due to people's deforestation, the beautiful Yangtze River and Yellow River have become muddy and dirty, even cut off. Human beings are the leaders of nature, which can make nature more harmonious and unified, and can also destroy nature. In recent years, in order to seek more economic benefits, people have seriously damaged nature, making many precious flowers and rare animals on the verge of extinction. Fortunately, people have now realized that the ecological value of nature is far greater than its economic value, so they have established various large nature reserves. However, people have paid a huge price for this. If people respect nature, they can save more money to invest in scientific research.
Nature is our home. By attacking and destroying it, we are pushing ourselves into a fire pit. In order to survive and develop better, we should cherish it and cherish it.
Natural beauty, sacred beauty, let's protect it together!
Let the beauty of nature become sacred and eternal!
I want to open my arms,
Fly to the sky.
I want to sing loudly,
A beautiful tomorrow.
Tomorrow is the new century.
Tomorrow is a new imagination.
Tomorrow is the wish of hundreds of millions of people.
I want to work hard,
Defend the motherland.
I want to stare with my heart,
Green home.
Home, everyone's home.
Home is everyone's dream.
Home is the hope of hundreds of millions of people.
We only have one home,
We should cherish it.
Green home,
The origin of our life.
Green home,
Our health care.
Protect the environment,
Starting with me,
Let's defend nature together.
* * * defend our home together.
-Earth
The earth is the home on which all things live and the veritable mother of mankind. In the past, the earth's sky was blue and clear, the mountains were green and the rivers were clear and pure. It's really beautiful, spectacular and kind. But what about the earth now? The sky is hard to find the blue of yesterday, the mountains and rivers are not the green of the past, and the rivers are lost in the past. Compared with the previous earth, there is no doubt that earth-shaking changes have taken place.
A little golden finch 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 escape, we still can't avoid the cruel reality that my father was killed by a ruthless hunter and my mother left this world to protect me. At the same time, I lost my parents, and I had to continue to look for a new home alone. ""did you find it? " Uncle Earth asked with concern. The little golden finch wiped her tears and said, "No, I only found the desert in full swing, the bare forest and the muddy river ... The world is so big, but I can't find a place to live and work in peace and contentment. "Goldfinch is too thirsty. It came to a small river and was about to drink water, but it was stopped by Uncle Earth: "You can't drink that water! Toxic! " Goldfinch couldn't help it. It said, "If I don't drink it, I will die of thirst. Anyway, it is better to die happily than to die horizontally or vertically! " Say that finish, it began to drink water, just took a sip, the little golden finch "ah!" " "With a cry, he died.
Are there fewer tragedies like the golden finch? We only have one earth, which is the only home for mankind. Humans, take action to protect the ecological environment! Otherwise, the consequences are really unimaginable! It's not too late to mend, and the earth can still be saved! Let's live together on this earth, enjoy a blue sky and enjoy the warmth of sunshine and rain!
The alarm bell has sounded, and it is time for mankind to wake up!
The earth doesn't need heavy makeup. I don't know when it becomes more and more beautiful. The color of sapphire makes it the most beautiful planet in the solar system. She keeps turning, and everything around her is constantly changing. I don't know when, a group of makeup artists-human beings appeared around her. At first, human beings just decorated some houses on the earth's body and tidied up the hair that had been left unattended for many years, making the earth look more beautiful and energetic. The makeup artist thinks it is wrong to dress up the earth like this. The earth is still the same, and it has not achieved a refreshing effect. As a result, they began to carry out large-scale cosmetic surgery on the earth. First of all, the object of makeup artist's rectification is the "lush" hair of the earth. They think that too much hair will affect the visual effect, and the hair of the earth 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 broken hair, the more broken the better, and get an unbreakable hairstyle-"San Mao". If you accidentally pull out that San Mao, it may become a "child mountain." So makeup artists don't know if it is possible for them to cut the earth into bald heads. In an interview with reporters, they said, "Our aim is to make her hairstyle avant-garde. How can we give her a haircut? " In order to get a lot of wood and make the hair style of the earth more avant-garde, they immediately broke ground. As everyone knows, according to their plan, it is inevitable that the earth will become a big bald head. Therefore, they invited many loggers and porters to move all the cut trees to the place where they planned to build houses. When buildings rise from the ground, the earth really becomes more and more beautiful, hair styles become more and more avant-garde, and makeup artists feel their greatness more and more. They think their bold design is successful. So they let loggers carry out predatory development and let architects build houses crazily. The earth, which once lived leisurely, no longer feels that life is easy. The roar of machines day and night makes the earth feel uneasy, and the dust flying during construction makes the earth breathless. As a result, the earth began to be sad and began to shed tears, flooding many cities. But makeup artists ignore these things, and they just keep doing theirs. They not only want to cut hair and make clothes for the earth, but also give her a "portrait". The originally blue face becomes turbid and rough as soon as the powder is removed. Not only that, they also painted her with a thick layer of paint. The earth has not become more beautiful because of their clothes, on the contrary, it has lost its mellow past. She can't stand it any longer. She started to get angry, she growled, and she shed tears. When the makeup artists were washed away by the tears of the earth, they realized that their makeup on the earth was so thick that the earth was about to stop breathing. They realized that they were torturing the earth instead of dressing it up, and they didn't make the earth glow with more charming colors because of their existence. So they began to unload the soil. Fortunately, they woke up too late. The earth without makeup is full of vitality, a relaxed face. When luxury comes to an end, the earth still turns leisurely.
What is a person?
There is a sentence written under a huge dinosaur photo: "Many behemoths have disappeared from the earth and will not adapt to change." What about that guy? What is a person? Is it a monster relative to ants, or a small ant at the foot of dinosaurs? Are they advanced animals that we call ourselves, or are they idiots who actually know nothing? Is it the owner of our lovely earth hukou book, or a group of poor slaves of nature? Oh, who is it!
Ever since there were humans on the earth, it has been neither fish nor fowl. It's said to be a monkey, but it can't jump from branch to branch. It's said to be an ape, with a little short arm, and doesn't like to do graceful movements of patting the chest.
This kind of thing is inherently destructive. It has ulterior motives to create a fire that can destroy everything, just as it makes an atomic bomb today. It tries every means to attack other innocent animals and leisurely shuttles through all the nutrient chains in the food chain-it will eat anything as long as it can eat. This ability is increasing with each generation. Now almost all animals in the world are rare except mice, and they are protected all day. Stop. It is also shameless to say that animals can't adapt to "change". It endlessly asks nature to turn her lush green into delicious black charcoal for cooking, her beautiful river into a carrier of sewage, her blue sky into riddled rags, and her originally wet and flat ground into a trap-like funnel. Even they are digging hard soil day after day, trying to squeeze out every element in her body-as long as she is comfortable. As long as they are comfortable, people are willing to do anything, shave their heads with tools invented by their ancestors, and some places still have pus and black smoke! The earth groans and cries. Will the next disappearing behemoth be the earth itself? Because she can't adapt to crazy humans! It is said that people don't care about it-they are still thinking about living on Mars, the sun or other places! It seems that mankind will not stop until the universe is turned into powder!
What is a person? I still don't understand.
Comment: Lu Xun said: "Laughing and cursing are both articles." Saying "what is man" is almost swearing. But sometimes, it is not as good as a heartfelt criticism, which makes people happy and easy to wake up. The author is interested in humans.
Selfish instinct crazily destroys the bad behavior of nature and ecology, and makes ruthless exposure and bitter ridicule. They all say that nature uses "she" and human beings use "it", and repeatedly emphasize that they don't know what a person is, which is neither fish nor fowl, and their dissatisfaction with human behavior is beyond words. Compared with all kinds of warnings, rules and even prayers, the article shows a pungent and sharp fighting style and a serious and cold character behind humor, which leaves a deep impression on people.
Development and environmental protection
If all countries in the world want to establish their prestige on the international stage, they must increase their efforts to develop their own economies. In industrial production, people seem to ignore environmental protection and just want to benefit from economic benefits. Don't think you haven't suffered. If you gain a share in the economy, you will suffer losses in environmental protection. Accumulate over a long period, and finally it is yourself who suffers.
After the founding of New China, China's industry has advanced by leaps and bounds, its economic value has increased a lot year by year, and its status in the international arena has also risen slowly, but the degree of environmental damage has also increased. Therefore, if we want to develop and protect the environment rapidly, we must take the road of sustainable development.
Since we want to take the road of sustainable development, we must proceed in an orderly way. We can't develop first and then treat, so we must give priority to "prevention", combine prevention with treatment, and treat comprehensively; Whoever develops, protects, pollutes and governs. Individuals alone can't achieve the expected goal, and we must also rely on the strength of the masses to protect the environment.
Let's work together to create our beautiful life!
