Causes and consequences of population growth

The progress of science and the improvement of living conditions have led to the rapid growth of the world population. For example, modern medicine has made it possible for babies to grow healthily and human beings to live longer. With the improvement of living conditions, especially in rural areas, people tend to have larger families. As a result, the world population has grown so fast that it has now exceeded 5 billion. But the excessive population growth poses a threat to the survival of human society. The huge population needs a lot of food supply and shelter space. However, limited productivity and scarce natural resources can hardly meet the needs of the growing population. Therefore, in the long run, the excessive growth of the world population will only harm mankind.

In order to ensure the stable development of human society, human beings must realize the consequences of rapid population growth and the importance of family planning. Only by taking effective measures can human society develop steadily and have a bright future.

The progress of science and the improvement of living conditions have led to the rapid growth of the world population. For example, modern medicine can make children grow up healthily and make people live longer. Due to the improvement of living conditions, especially in rural areas, the number of family members is increasing. As a result, the world population has grown so fast that it now exceeds 5 billion.

However, the excessive population growth poses a threat to the existence of human society. A large population needs a large food supply and a large number of houses. However, limited production capacity and insufficient natural resources can hardly meet the needs of the growing population. Therefore, in the long run, too many people in the world will do harm to mankind.

In order to ensure the stable development of human society, human beings must be aware of the consequences of rapid population growth and the importance of implementing the family planning policy. Only by taking effective measures can human society develop steadily and have a bright future.

With the rapid growth of population, there are more and more people on the earth, and there is no longer enough food and land for so many people to use. Excessive population has caused many environmental and social problems, such as crime. We must find more resources to feed so many people, but we only have one earth, and everything is limited. Employment pressure, education pressure and medical problems are becoming more and more serious. Article on food: People in different parts of our country have very different ideas about what is good. Go to eat. For example, in our country, southerners like rice, while people living in the north like bread or noodles. Hunan or Sichuan people like spicy food, while Shanghai or Suzhou people like sweet food. However, even if people live in the same part of the country, their tastes are very different. Old people and young people have different tastes; Men and women also have different preferences. In restaurants, some customers order thick and heavy soup, while others drink thin and clear soup. A few people only eat vegetables. They don't eat fish or chicken. Therefore, it is not easy for restaurants to meet the needs of all customers. In order to increase business, restaurants in the city try their best to prepare different kinds and styles of food. They are constantly adding new dishes to the menu to cater to different tastes of customers.

There are 90 words left in the English composition about "The rapid growth of the world population has brought us many problems" ... It is reported that the world population was 6 billion in 2000, and the growth rate is getting faster and faster. The world population problem is the biggest problem, because it brings many problems, such as water resources, more and more people losing their jobs and so on. These problems are mainly in developing countries, because the population of developing countries exceeds five quarters of the world population. Therefore, as the largest developing country, China has always adhered to the policy of "one child for a couple".

English composition: The troubles caused by population growth This is a CET-4 composition on population problems. It is estimated that there were less than 400 million people on the earth a thousand years ago. Today, however, the world population has reached 5 billion. To make matters worse, it has been growing at an alarming rate. If this trend continues, the world population will soar to 7 billion by the year 2000. This is what we call a population explosion. The rapid development of science and technology is the main reason for the population explosion. We can see that the population has been growing at an alarming rate since the industrial and agricultural revolution in 1650 improved people's living standards and the emergence of modern medicine in 1550 reduced people's mortality. Population explosion will lead to many problems, such as food shortage, housing shortage and unemployment. It's time for us to implement the family planning policy quickly, otherwise, the survival of mankind on the earth will be threatened. What are you willing to do for endangered animals? Maybe you can also write an article about your favorite animals and call on people to take action to protect wild animals. The following words will help you: furry, * * * art, smart, fast, strong, aggressive, noble, interesting, shy, friendly, endangered, law, zoo, feed, etc. One possible statement is: My favorite animal is the panda. I like them very much because they are gentle and shy. They are also very friendly to people. They also look interesting. Their eyes are the most interesting part. The dark circles around their eyes make them look like they are wearing glasses or have just had a fight. Their favorite food is bamboo leaves. They don't like walking around very much. In fact, if possible, they would rather sleep all day. But now pandas are on the verge of extinction. First of all, people have destroyed many habitats. Secondly, they don't have enough food to eat. We must find a way to protect them. I think we should build more panda zoos and plant more bamboo for them. I hope everyone can do something for animals, so that we can keep our world colorful and full of interesting animals. B this year, the heads of several world powers attended the August meeting. The themes of this conference are world economy, energy issues and climate change. Economic development is inseparable from environmental topics. The use of energy will inevitably pollute the environment, and climate change is the product of the contradiction between economic development and environmental problems. Planting trees is very useful and important for us. In order to live better and happier, we should plant more and more trees. In the future. In order to live better and healthier in the future, we should plant more trees. It is everyone's responsibility to care for and protect the environment. It is everyone's responsibility and obligation to care for and protect the environment. It is our responsibility to save water. As we know, water is very important to human beings. ) We can't live without water. We can't live without water. The amount of water suitable for drinking is getting less and less. There is less and less water suitable for human consumption. ) But some people. I don't care about it. But some people don't care or don't care at all. They consume a lot of water in their daily life. They waste a lot of water in their daily life. To make matters worse, they poured dirty water into the river.

It is very important to save our city and die with the garbage in the city. Garbage must be thrown away or reused. Exactly. Otherwise, it may cause many problems. It may pollute the air and water. When people breathe polluted air or drink polluted water, they may get sick. Our city has begun to face this problem. Some rubbish is sorted and sent to a certain place. The waste gas was purified before it was discharged into the air. Waste water should also be purified before it is discharged into rivers. People should be stopped from throwing rubbish everywhere. We should do our best to protect our environment and fight pollution. D. saving the earth) as time goes by, human beings are making the earth sick. People cut down too many trees and litter everywhere. Factories discharge waste, but they don't treat it in An Ying. This has caused some serious problems. For example, the land is sandy, the rivers are dirty and the air is dirty. ...

The rapid growth of the world population has caused many problems. In particular, the population growth rate of some underdeveloped countries has affected the economic development, social stability and the improvement of people's living standards of the whole country, and brought many problems to human life. World Population Problem In order to solve the problem of rapid population growth, human beings must control themselves and have children in a planned way, so that population growth can be coordinated with social, economic development, environment and resources. The rapid growth of the world population has caused many problems.

In particular, the population growth in some economically underdeveloped countries is too fast, which affects the economic development, social stability and the improvement of people's living standards of the whole country and brings many problems to human life.

In order to solve the problem of rapid population growth, human beings must control themselves and have children in a planned way, so that population growth can adapt to social and economic development and be in harmony with environment and resources.

There is a close causal relationship between population and environmental problems. At a certain stage of social development and geographical conditions with a certain level of productivity, the population should be maintained in an apportionable range to promote reproduction. Population problems are closely related to environmental problems. At a certain stage of social development, under a certain geographical environment and productivity level, population growth should be kept in an appropriate proportion.

The rapid growth of the world population has caused many problems. In particular, some developed countries with overpopulation and rapid economic growth have affected the country's economic development, social stability and people's living standards and brought many problems to human life. World Population Problem In order to solve the problem of excessive population growth, human beings must control themselves, achieve family planning, and coordinate population growth and socio-economic development with environment and resources. The rapid growth of the world population has caused many problems.

In particular, the population growth in some economically underdeveloped countries is too fast, which affects the economic development, social stability and the improvement of people's living standards of the whole country and brings many problems to human life.

In the1970s, it was considered to account for 75% of the total population who had lived on the earth at that time. The widely quoted statistics have been greatly influenced by the population explosion in the 20th century-the proportion is incredibly high. In order to get more accurate results, we must determine when modern humans began, what is the birth rate, and how many people have lived in history. It is generally believed that modern people were 50 thousand years ago. As we can imagine, there is no restriction on the birth of the population, and the life expectancy is very short, which leads to a young population and a higher fertility rate-the health level of each mother is about 6 to 8 children. By the middle ages, the birth rate began to decline for a long time. Records show that since18th century, the birth rate has been declining continuously. CarlHaub, an American demographer, believes that before agriculture and hunting appeared, the world population was only about 5 million to100000. According to the news of light, by the year of 1 century, according to the closed census of Rome, China and the Mediterranean, the world population has increased to 300 million. Using this high birth rate, we can estimate that there are about/kloc-0.06 billion people living on the earth so far. We now have 6 1 100 million people, accounting for 5.7% of the total population of life on earth. In 1900, the world's population was only160,000, but the rapid population growth in developing countries led to a sharp increase in the world's population, so we had the population growth to promote the growth of the earth's population. In the 1970s, people thought that the population at that time would account for 75% of the total population that once lived on the earth.

This widely quoted statistical result is too influenced by the bombing of people in the 20th century-the proportion is incredibly high.

In order to get more accurate results, we must determine when modern human beings began, what is the birth rate and how many people have lived in history.

It is generally believed that modern people appeared 50 thousand years ago.

We can imagine that there was no limit to the birth of the population at that time, and people's life expectancy was very short, which led to a younger population structure and a high fertility rate-each mother would probably have six to eight children.

In the Middle Ages, the birth rate began to decline for a long time.

/kloc-Records after the 0/8th century show that the birth rate in industrialized countries continued to decline at that time.

CarlHaub, an American demographer, believes that before the emergence of agriculture, the world population only depended on hunting for about 5 million to 6.5438+million.

According to the light of science and technology, by the 1 century, according to the intermittent population censuses in Rome, China and the Mediterranean at that time, the world population had increased to 300 million.

Applying the higher birth rate to this part of the population, it can be estimated that there are about 654.38+006 billion people living on the earth so far.

We now have a population of 66,543.8 billion, accounting for 5.7% of the total population who once lived on the earth.

1900 The world population is only1600 million, but the rapid population growth in developing countries has led to a sharp increase in the world population, so the proportion of our existing population to the pre-Earth population is rising.

Nowadays, mankind is facing many thorny problems: energy crisis, cancer, polarization, population explosion, science and technology. They threaten the survival of mankind. Therefore, some people are pessimistic about the future of mankind. They are pessimistic because they think that the limited energy on the earth will soon run out; An incurable disease is threatening the lives of more people; Pollution is worsening the environment; The population explosion will aggravate the food shortage. In fact, they don't have to worry too much about these problems. When oil and coal are used up, scientists will have developed new energy sources. In addition, scientists are conducting a thorough study of genes, and they will treat cancer by adjusting the arrangement of genes. They are also trying to control pollution and population. Besides, all the governments in the world are concerned about these problems, and they have taken measures to solve them.

Problems brought about by population growth English 80-word composition There are more and more people on the earth now. It has brought many problems to the earth. Because there are too many people, we don't have enough living space. We don't have enough houses to live in. The streets are crowded with people. The traffic is very busy. There are not enough medicines for patients. So we should take measures to control the population. We should not allow people to have too many children. In this way, we can reduce the population growth rate. ....

The population growth in the past few centuries does not prove that the population will continue to grow indefinitely. Bad luck. On the contrary, population history provides evidence that population growth is not constant at all. According to the paleoecologist Edward Dewey, the past million years have shown three major changes. The first time was around1000000 BC. With the innovation of tool manufacturing and use, the population grew rapidly. However, when the new power of tool use was developed, the world population growth rate declined and became almost stable. The next rapid population growth began about10,000 years ago, when humans began grazing, farming and planting land. When the initial productivity growth was absorbed, the population growth rate dropped again. These episodes show that the third great revolution, that is, the current rapid growth that began in the West 250 and 350 years ago, may also slow down when technology begins to produce less innovation. Of course, the current knowledge revolution may continue with no end in sight. In any case-contrary to the generally believed constant geometric growth-in the long run, the population can adapt to the productive forces. When people hold this view, population growth is regarded as representing economic progress and human victory, not social failure.

The progress of science and the improvement of living conditions have led to the rapid growth of the world population. For example, modern medicine has made it possible for babies to grow healthily and human beings to live longer. With the improvement of living conditions, especially in rural areas, people tend to have larger families. As a result, the world population has grown so fast that it has now exceeded 5 billion. But the excessive population growth poses a threat to the survival of human society. The huge population needs a lot of food supply and shelter space. However, limited productivity and scarce natural resources can hardly meet the needs of the growing population. Therefore, in the long run, the excessive growth of the world population will only harm mankind. In order to ensure the stable development of human society, human beings must realize the consequences of rapid population growth and the importance of family planning. Only by taking effective measures can human society develop steadily and have a bright future. Scientific progress and the improvement of living conditions have led to the rapid growth of the world population.
