The air also contains water vapor, carbon dioxide, sulfur oxides, nitrogen oxides, dust and other gases and substances. If the content of sulfur oxides, nitrogen oxides, dust and other harmful gases and dust in the air is too high, the air will be polluted. The more these harmful gases and dirty things are mixed in the air, the more serious the air pollution is, and the greater the harm to people, animals and plants.
Air pollution is harmful to people's health first, and then affects the growth of animals and plants. If measured on the spot, it will also cause global climate change. Air pollution leads to human respiratory diseases and increases mortality.
The mortality rate of lung cancer in heavily polluted areas of Chongqing is increasing year by year, exceeding 50 people/65,438+10,000, which is 4.7 times that in relatively clean areas. The mortality rate of lung cancer in individual blocks in Changsha is as high as 94 .36/65,438+10,000.
2. Harm of greenhouse effect and climate warming to human body In recent decades, due to the influence of human activities, especially the sharp increase of energy consumption and the destruction of forests, the content of carbon dioxide in the air has been increasing, which has made the greenhouse effect continuously enhanced and the global climate has become warmer. This will increase the incidence of respiratory diseases, cancers and headaches, and contribute to the occurrence and spread of tropical epidemics such as malaria.
3. The influence of acid rain on human production and life. Acid rain is called "God in the sky", which can acidify soil and lakes, thus making forests decline and wither, and many aquatic organisms cannot survive. Thus affecting human production and life.
Moreover, acid rain will erode cultural relics and buildings. 4. The influence of water pollution.
The consequences of water pollution are serious, which not only causes losses to industrial and agricultural production, but also greatly reduces the catch of freshwater fish. The output of many rare fish species, such as Yangtze River shad and Heilongjiang salmon, decreased sharply, and some even disappeared. Poisoning incidents of fish, people and animals caused by national pollution occur frequently, and the incidence of digestive system cancers such as liver cancer, stomach cancer and esophageal cancer is increasing year by year. The water pollution in China has reached the point where it must be treated.
Noise pollution has a great influence on residents' life and health. According to the statistics of 29 environmental protection departments, more than 30% of the people sent letters and visits to reflect the noise problem. The incidence of deafness, hypertension, heart disease and neurasthenia in some factory workers is as high as 30%~60%.
According to the statistics of the Department of Otolaryngology, Shanghai First Hospital, about 1/3 of patients with otopathy is caused by noise. In some areas, noise has threatened the intellectual development of teenagers.
According to the forecast of relevant departments, by the end of this century, 85% of urban residents in China will be unable to work and live normally unless measures are taken. The materials provided are for reference only.
I wish you progress in your study.
The earth's environment will be better in one hundred years. What will the earth look like in a hundred years? Is it green or bare? I think it should be green, because humans no longer throw garbage into the bright eyes of the earth, cut off the green hair of the earth, and discharge sewage into the blood of the earth ... At this time, the earth has become a beautiful girl of seventeen or eighteen.
At that time, smart people made smokeless cars. Just give it a bottle of water and it can walk all day. Without black exhaust gas, the earth will wear that beautiful light blue tulle every day and travel in the solar system.
Walking on the road, as long as someone litters, there will be a kind exhortation not far away: "Please give me the garbage, thank you!" " "It turned out to be a new trash can with electronic eyes and electronic mouths. After receiving the garbage, they will automatically sort it, and automatically make recyclable garbage such as peel vegetables into delicious food for piglets, and put it in a special box for easy collection.
Every year on Arbor Day, if the school organizes every student to plant trees, a hundred years later, our home will be full of paradise for trees and birds.
3./kloc-the composition of the earth after 0/00 years. I came to the earth on 2 1 10 by "time shuttle". The houses here are all made of glass, so that people can't see the outside from the inside and the inside from the outside. The taxis here are unmanned! Later, I learned that this kind of taxi can drive automatically. Just tell the destination and it will arrive accurately. This kind of taxi can not only drive automatically, but also avoid obstacles automatically!
Then, I took this taxi to the underground aquarium. I really don't understand why it's called an underground aquarium. At this time, the robot greeter next to him explained, "Because the aquarium goes all the way to the depths of the ocean." I went through a corridor to the aquarium, where all kinds of fish swam freely in the water. There are also many tourists who put on diving suits and go downstream to play with fish in the sea accompanied by staff. How amazing all this is!
At dinner time, I walked into a restaurant, only to see something similar to hospital infusion. I thought to myself: Am I wrong? It turns out that the chef here has come up with a wonderful way: make food into nutrient solution and input it into people's bodies. In this way, people can not only "eat enough" but also supplement nutrition, which really kills two birds with one stone! I lost fifteen minutes, walked out of the hotel and found a hotel to stay. The next day, I returned to 20 10 by "time travel".
/kloc-what will the earth be like in 0/00 years? After 400 words 100 years, the earth's air is fresh and the environment is beautiful. With the rapid development of high technology, everything on the earth has undergone earth-shaking changes. A hundred years ago, people wantonly wasted resources and abused chemicals. But it's different now. People protect the environment and save resources. Therefore, with unlimited resources, people's lives are very happy. A hundred years later, cars can be charged without oil, and it is very convenient-as long as there is light, they can be charged, and even flashlights can be used. Every minute they see the light, they can spend 24 hours. Therefore, people no longer have to worry about running out of oil. A hundred years later, the house is even huge. There is a display screen and a pen on the wall of its living room. All you have to do is write the name of the place you want to go on the screen with a pen, and you will go in five seconds. Moreover, it can choose any means of transportation. If you write about an airplane, it will fly; if you write about a train, it will run on the rails. This is very convenient for our trip! Anyway, the earth in one hundred years is definitely a high-tech earth, but we should study hard to realize this great fantasy and turn it into reality.
One hundred years later, when the last person on the earth was sitting at home, someone knocked at the door. ...
He was surprised that he was the only one left on the earth. Who will knock at the door? He stood up weakly and opened the door.
A very strong young man stood outside the door and said politely, "Hello, I'm an emissary from the planets in the universe. I regret to inform you that we will blow up the earth in 10 hours. Please come with me. " "Why? Who decided? Don't ruin my home! " "Is the universe planet * * * with a vote, the earth pollution is too serious, has harmed other planets, we are also forced. You still have 10 hour, please pack your things. "
The messenger turned and left, leaving only the crying earthlings.
It turns out that as early as a long time ago, the earth has been seriously polluted, with a large river bed, beautiful scenery no longer exists, and the population has dropped sharply ... The last survivors can only stay at home every day, sucking the only oxygen left. But what happiness is there in this life? Health and love have abandoned him. Now, the earth will come to the end of its life. ...
Time goes by quietly, and the earth people count down in their hearts. He thought, who is to blame for all this? A beautiful home and a happy life were destroyed by human beings themselves, which was self-inflicted!
9 hours and 59 seconds arrived. As soon as the earth people left with the cosmonaut, they heard a loud noise behind them, and countless pieces of the earth were flying in the universe.
Tens of thousands of years later, on the celestial sphere (livable planet), a little girl stared at the starry sky. She found that there were always some objects floating like stars, so she asked her grandmother, "Grandma, what are those floating?" Grandma thought for a moment and said, "That should be a fragment of the earth." "What is the earth?" Grandma smiled and said, "It used to be a very beautiful planet, and it was also a myth that passed down through the ages ..."
/kloc-the earth in 0/00 years.
I woke up and looked at my calendar. Oh, my God! Actually, it is 2 1 10 year. I was shocked. Look out the window. This is a planet composed of three colors: blue, black and yellow. Turn around and get out of bed, and find a robot beside you. It claims to be my housekeeper. I thought even robots would be like computers, so I pointed to the planet and asked it, "What's the name of that planet?" It says, "Earth!" Suddenly, I was shocked. I feel my heart shaking violently. It was a long time before I came to my senses and stammered, "Is this really the case ... in fact ... the earth?" ..... Then where am I now! How ... how did this happen? " After a while, I saw it shoot light from my eyes and shine on the wall like a projector. An image appeared on the wall. It pointed to the image and said to me, "You are living in an China house on the moon. The reason why the earth has become like this is because human beings do not cherish the environment. You know, technology has two sides. Although human beings have advanced technology, they don't know how serious the environmental pollution is.
Although human beings have changed their lives with science and technology, they do not cherish the environment. Since the invention of automobiles, batteries and airplanes and the construction of a series of factories, a large amount of waste gas has been discharged into the atmosphere, which has made the hole in the Antarctic ozone layer almost extend to the south temperate zone, and also melted all the glaciers in Antarctica, which has caused the water level of the earth to rise a lot. However, human beings are not satisfied, and continue to discharge pollutants, which has polluted the fresh water resources of the earth. Humans have no fresh water, so they thought of a way, that is, boiling seawater and releasing steam. In the end, human beings used up all the combustible materials such as natural gas on the earth, and even extended their evil hands to the trees in the forest. Later, they burned all the trees on the earth. Finally, they realized that they flew to the moon and Mars, and there was only a little electricity left, and you have lived on the earth since then. On the earth now, nothing grows, and there is yellow sand all over the sky. The situation is very dangerous.
Suddenly heard a burst of * * *, turned out to be a dream. This dream is really terrible. Humans should stop destroying the environment, otherwise it may become like this.
6. The Earth in One Hundred Years' Time 700 words The Earth in One Hundred Years' Time
The earth is the only place where human beings live and the hometown of human beings. Like her mother, she has made great contributions to mankind. However, the rapid growth of population makes the earth more crowded. Moreover, among the beautiful and young Mother Earth, she is now old and has become the first victim of human destruction of the environment!
One hundred years later, this loving, beautiful and young human mother came back to us. She was full of vitality. ...
In the morning, birds are singing in the branches, people are sleeping, the sun rises in the east early and shines on all the creatures on the earth ... The vegetable garden is full of vitality and laughter.
"ah! Guys, it's not a good idea for us to be so quiet. Let's be happy! " The impatient green pepper opened its mouth. Cucumber said with a smile: "Although we have a lot of troubles, what makes us most happy is that the original alma mater of the earth is back, and human beings know how to protect the environment!" " "After the cucumber said this, the vegetables were all very excited and scrambled to speak one by one. The small animals in the forest looked at the excitement in the vegetable garden and leaned in. The panda said, "Let's have a forest party!" " "Everyone agreed. The white swan jumped into Swan Lake first, and then the white-headed langur took out his housekeeping skills and turned it upside down. Black-necked cranes, Yangtze geese and golden monkeys are also eager to try ... everyone is celebrating the return of Mother Earth to them again.
Humans have aged Mother Earth, and all kinds of flowers, trees and wild animals have given her a beautiful face and a young heart ... Humans have realized that they have compensated their sins by actions, planting trees for their mothers and the earth. Year after year, day after day, pollution control of rivers and lakes. ...
At night, the blue sky shakes the little star and the moon bud to sleep. Mother Earth looked at the beautiful starry sky and smiled with relief.
7. One hundred years later, the composition with the theme of the earth is about 500 words. Time flies, the sun and the moon fly like a shuttle. In an instant, 20 years have passed. By this time, I have set up a big company and become a big boss. Nevertheless, I still miss my hometown, because that's where I live and there are good memories of my childhood. Busy for several months, finally arrived at the National Day. It's rare to have a holiday. You should go back to your hometown. So I told the robot nanny to look after the house and set off at once.
I returned to my long-missed hometown with a folding plane. Ah! I finally came back. At this time, I was broad-minded and full of thoughts, and a little warmth flowed into my heart. How warm and kind my hometown is!
Arrive at Endeavour Square in Jiangbei New Town. I remember when I was a child, I used to chase, play and fight with my classmates in this square ... how naive and happy I was! Now, I don't know what my former friends are busy with. Alas! We should go to them. Now, many recreational facilities have been built here, such as water skating rink, underwater surfing, pirate ship and bungee jumping bed, which have become a paradise for children to play.
Then I walked around the street and looked up. Wow, the original ordinary buildings are now replaced by magnificent intelligent high-rise buildings. The staff showed me around the house. The room is spacious and bright with fresh air. As long as the owner sits on the sofa and presses the ammonium button, the robot nanny can present anything he wants, which is very convenient. I didn't expect my hometown to change so quickly that it could rival London in England!
In the past, the exhaust gas from cars would pollute the environment. Now, a "smoke eliminator" is installed at the rear of each car, which will absorb the exhaust gas bit by bit. It is really happy to let people live in an elegant and quiet environment.
I didn't expect my hometown to change so much in just 20 years. Among many words, I only think the word "hometown" is the kindest and warmest. Whether it is a backward hometown or a modern advanced hometown. As long as I come back here, it will make me feel particularly warm.
8. Write a short essay on protecting the ecological environment with the theme of 50 years of the earth. One day in 2055, the telephone of the hospital emergency center kept ringing.
On the wide road, a shrill alarm sounded "beep-beep-beep-beep". Ambulances shuttled along the road like arrows.
The patient poisoned by inhaling polluted air was sent to the intensive care unit of the hospital. A critically ill patient was taken to the emergency room; Groups of deformed people were pushed into the operating room. Hospitals are several times more lively than holidays! At this time, it is hot summer, and the strong and harmful ultraviolet and infrared rays in the sun easily pass through the ozone layer. The ozone layer used to be its nemesis, but now it is full of loopholes and hits the earth directly.
Without the newly invented multifunctional sun umbrella, people dare not go out. Most plants and animals on the earth died out in the early days, and it is extremely rare to survive now.
The air inside and outside the window is very dirty, and it seems to be some dirt; It was dark between heaven and earth, as if there was going to be a strong big explosion on the earth. The big chimneys in the factory spit out clouds of black smoke, like cigarette butts that will never go out. The water in the small lake is black and smelly, smells bad and smells musty. All the dead branches and leaves are floating on the river. Plastic bags are flying all over the sky ... everything on earth is worrying.
Because the oil on land has been exhausted, oil exploration workers went to the sea to collect oil, leaving a very ugly hole on the seabed; Miners drive deafening machines, as if to dig through the earth; All the resources on the earth will be destroyed in human hands! I felt very uneasy about this matter and went to the staff of the Environmental Protection Bureau. After that, I saw that the door of the Environmental Protection Bureau was locked.
In the message room, a few thin people were smoking there, which made me feel even worse. Just when I was desperate, I don't know who stripped me.
I woke up suddenly and realized that all this was my nightmare. The picture in my dream has been in my mind for a long time.
In order to prevent the "tragic scene" in our dreams from becoming a reality, let's be "little guardians of environmental protection" together, starting from individuals and starting from small things.
9./kloc-the earth after 0/00 years and the earth after 450 years are estimated to be not much different from Mars.
According to satellite observation, there were once humans (or intelligent life) on Mars. Personally, I feel that there are signs that Mars once had intelligent life. It is estimated that they will either look for another planet to survive or be completely destroyed.
Now the earth is developing too fast, and the development of science and technology can't keep up with the destruction of the harsh environment. That is to say, when the earth's environment is destroyed and human beings can't survive, we humans can't carry out another planet that Ad Astra can provide for human survival.
Some people may say that we can build a perfect world in the sea (when the land is seriously damaged and the sea still exists), and it is estimated that technology is enough.
It is very likely that the original story of Noah's Ark is true. Because of the natural environment, we human beings are very small in nature, unless technology advances to the height of science fiction films, but this is very difficult.
On the one hand, the earth's environment, on the other hand, is the human itself, such as war.
It may be that after 100 years, water resources will be extremely poor, and the war caused by it is estimated to be the same as that caused by oil now, and it will be even bigger in the future. In order to survive, everyone will try their best.
If it is a conventional strategic weapon, if a country drops a nuclear bomb first, the earth will definitely be destroyed by a nuclear bomb. Not to mention blowing it up, radiation can also greatly reduce the survival of mankind.
There are more aspects, I think I can live to 70 80. Although the above personal guess is a bit exaggerated, I don't think this will happen after 100 years, and it will definitely be destroyed after 200 years (without human understanding).
Although we are talking about environmental protection now, a large number of people still turn a deaf ear because it has nothing to do with their immediate interests. Why do they want to protect the environment? Some black-hearted bosses continue to destroy the environment (unless they are caught), but just like me, I will do the same when I see others do it. Environmental protection has not reached the point where it affects our survival. How much can I do? The same mentality can be seen everywhere on earth.
Let's talk about the nuclear bomb problem of war first. Now it's just that everyone is in a stage of forbearance, because there is no final bottom line to trigger the interests of all countries, and everyone will not be crazy. If the environment is so bad that a bottle of water costs tens of thousands, then war will inevitably occur, and few people will survive in the end, and a new round of cycle will begin.
Hey, having said so much, live in the present! ! ! .
10. What will happen to the earth after one hundred years? The earth is home to many creatures. In the life course of hundreds of millions or even billions of years, the earth has experienced too many vicissitudes.
But now we are all spoiled, and the environment is changing too fast! At the beginning of our earth, the environment was comparable to a fairyland: water flowed in the bushes, and all kinds of strange insects and animals played in the mountains and streams; In the sea, many strange animals and plants live peacefully ... now we have turned this "fairyland" into a "hell" situation. For more than 8000 years, humans have killed a large number of animals.
In ancient times, we killed cattle and sheep to fill our stomachs, which was nothing. The most painful thing is the "blood station" for decades: because sharks hurt humans, humans fished it up with a hook weighing dozens of kilograms, then "cut it open", cut off its fins, and finally threw it into the sea. The seawater turned red ... The cut fins were made into "fishtail soup".
Fish's tail soup is a famous dish, and it costs two or three hundred yuan a plate. In fact, the fins didn't play any role in the soup at all, but the seasoning brought out a little taste.
I remember once, a large number of whales were salvaged by humans, and their fins were cut off and thrown into the sea ... I really don't want to believe that this was done by humans! We saved lives tens of thousands of years ago. Isn't it thanks to biology? Why should we kill each other? Let's not give up the big earth, for ourselves! Today's oasis is almost a Gobi, and Minqin, which is close to or even surrounded by Gobi, is sometimes bullied by the "old demon" of the black wind. The trees were cut bare; The grass was trampled flat; The water is polluted and stinks; The sky becomes gray.
