The plane passage can actually attract some inherent substances, whether those things are some treasures or some precious medicines, but they can pass through the plane passage, and these resources are the most powerful treasures for the aliens on the earth.

Because of this reason, the entire earth is caught in the competition for these plane passages, after all, whether in reality or within the ability realm, resources are limited, not infinitely reborn, and some top resources are used up a little less. One person uses some, and the other will definitely use a lot less.

In this way, whether it is for the sake of one's own strength, or in order to prevent others from appropriating these resources, then a round of struggle is inevitable.

This kind of situation will be more serious, especially after the great awakening of the supernatural and the number of supernatural people increases. This situation is similar to a real piece of history.

In 1798, the English economist Malthus published one of his pamphlets, entitled The Principle of Population. The central idea of the book is that population growth can be infinite, while the amount of food is definite and finite, and that the number of people will exceed what food can sustain. Since the growth of food cannot keep up with the growth of population, natural and man-made disasters such as wars, plagues, and famines will accompany mankind.

Malthus's "population theory" caused great social repercussions at the time, and also had a profound impact on the research of population in later generations. In the 20th century, the British economist Keynes's theory of effective demand was heavily inspired by Malthus's "effective demand theory", and Keynes called Malthus "the first Cambridge economist". "Having a deep economic intuition is not only able to keep an open mind to the changing empirical picture. and has been explaining experience in the light of the principles of his normative thought".

In 1796, Malthus wrote an essay entitled "Crisis. A Constitutional Proponent's Views on the Recent Interesting Condition of Great Britain", which deals with socio-political-economic issues, including demographic questions, but no one wants to publish it. In 1798, at the age of 32, Malthus published his Principles of Population, which was entitled On Population; the impact of population on future social progress; Commenting on the theories of Mr. Godwin, Mr. Condorcet and other authors. In 1803, Malthus supplemented and revised the Principles of Population, publishing a second edition under his real name.

In 1793, the British philosopher Alexander Godwin published Political Justice, a book that attacked the existing social system from an anarchist standpoint. In his book, Godwin argues that improving society with justice will eliminate all sin and poverty. Thus attaining the complete state of rational human society. In 1794, the French philosopher Condorcet published "The Evolution of the Human Spirit", which advocated that the evolution of the human spirit promotes the evolution of human beings, believed that the poverty of the people was caused by the defects of the social system, and therefore demanded the improvement of the social system.

Malthus started by criticizing them, arguing that human poverty and evil do not come from institutions, but from the growth of population and food, and he linked the problem of population to the future of mankind. He thinks of himself as "studying the obstacles to the progress of human society due to the fact that the population is growing faster than the human ability to survive." ”

In his book The Principle of Population, Malthus said: "I think I can put forward two reasonable assumptions. First, food is essential for human survival. Second. Erotic desires between the sexes are bound to exist and will remain as they are almost forever...... Suppose, then, that the two assumptions I have proposed are accepted. I can say that the multiplicative power of the population is infinitely greater than the ability of the land to provide human resources for survival. Once the population is not suppressed, its growth will proceed in geometric proportions. And the means of subsistence will only increase at an arithmetic rate. Anyone who knows a little bit of arithmetic can see it. Relative to the latter, the former's immense power. ”

Malthus added: "Suppose the world's population is arbitrary, let's say 1 billion. then the population will be 1, 2, 4, 8, 16, 32, 64, 128, 256, 512...... and the means of subsistence are increased by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10...... multiples of the increase. After 225 years, the ratio of population to the number of means of subsistence will be 512:10, and in 300 years, it will be 4,096:13, and after 2000 the difference between the two will be incalculable, although the output of the means of subsistence will increase to an alarming degree. ”

The publication of The Principle of Population coincided with the flourishing of the Industrial Revolution in the West. Malthus's use of two mathematical progressions to reflect the relationship between population and food growth is a pioneering achievement, and it also basically summarizes the basic characteristics of the growth of human resources in the industrial age. Malthus's idea has caused great repercussions in society. On this basis, both the natural sciences and the economics circles have published many works and theories on the development of economic and social development. Of course, after the publication of Malthus's "The Principle of Population", it also aroused criticism from some scholars.

In the early 70s of the 20th century, with the assistance of a 152-member Communications Committee from 58 countries, Barbara ? Ward, René? Dubos's Only One Earth, an unofficial report prepared for the first United Nations Environment Assembly in Stockholm in 1972, describes how "the world's population gradually increased from the level of the number that Neolithic agriculture could support to about 400 million by the time of the fall of the Roman Empire." It took 1,000 years, around 1600 AD, for the population to reach its first billion. Since then, population growth has begun to accelerate. This is the result of the accumulation of momentum from the industrial revolution, which led to an increase in both industrial and agricultural production, as well as a continuous decline in mortality, especially infant mortality. After only 300 years, by 1900, the population had reached its second billion. The third billion only passed 50 years (to 1950). By 1980, it would only take 30 years, and we would soon reach the fourth figure of 1 billion people. This result also seems to support Malthusian theory that the population is growing in a geometric progression.

The French economist Walras said: "Malthus's theory of population contains two aspects, one is that the population will grow in a geometric rate, and the other is that the production of food, the means of subsistence, will increase at an arithmetic rate." The gap between the two cannot be bridged. Malthus's first argument is almost absolutely correct, according to the general laws of reproduction in the biological world. The population will increase exponentially from one generation to the next, if the means of subsistence are sufficient. It is true that the population will increase in a geometric progression. The rate of population growth seems to be an indisputable fact. The second inference, on the other hand, does not contain the correctness of the first inference, fails to distinguish between technological development and economic development, and does not adequately take into account the impact of technological development on food production. Because, if technological factors are added, both food production and population increase geometrically, but the former is slower than the latter. ”

From now on, Walras may have been the first scholar to propose the impact of technological development on social production, but he did not escape Malthus's conclusion in the end. Forty years after the publication of Malthus's The Principle of Population, Engels also discovered the flaws in Malthus's thought. He argues that if the population grows exponentially, so does the labor force that produces food. Engels emphasized labor productivity and the ability of the population to use science and technology to meet needs, so the Malthusian law was not immutable. Engels corrected Malthus's conclusion, and this scientific assertion has been proven by the practice of the development of science and technology in modern society.

Looking back at the history of England, from the plague and famine that occurred at that time, Malthus has reason enough to wonder whether human society is destined to suffer from a constant crisis of resources. When all the food and fuel that nature provides to human beings reaches the limits of nature, that is, when all arable land is cultivated, it is still not enough to eat. Humanity is going to starve. With the production technology of 1798, this is obvious. In the view of classical economists, land greatly constrained the growth of social wealth, and no society could escape the restrictions imposed by nature. But. After the industrial age, the situation changed radically, and people reduced the demand for land used to produce food. It is not a decrease in population, but an increase in the efficiency of land use. And the economic importance of land, the most important factor of production in the agrarian era, has declined dramatically relative to other resources.

In the classical theory of economic growth. The analysis of the relationship between population growth and economic growth was largely pioneered by Malthus, who first saw population growth as an important part of the theory of economic growth. In Malthus's view, both the finite nature of resources and the economic scarcity are absolute, and Malthus's idea is considered to be the theory of absolute scarcity of resources. In modern economic growth theory, Malthus's theoretical model is summarized as the "Malthusian trap".

After the Second World War, a pessimistic view of the world's population development prevailed in the West. The main representatives and works are: J.W. Vogt's "The Road to Survival" (1949), J. W. Vogt's "The Way to Survive", J. W. Vogt's "The Way to Survive" (1949), J. W. Vogt's "The Way to Survival" O. Hetzler, The World Population Crisis (1956), P. Hetzler, P. Hetzler, The World Population Crisis, P. Hetzler, P. Hetzler, The World Population Crisis, P. He R. Elrich's "The Population Bomb" (1968), G. Taylor's "The End of the World" (1970), D. L. Meadows's "The Limits to Growth" (1971), A. Pechey's "The Future of the World" (1981), and many more.

Using population statistics, the growth rate of food, and the degree of resource consumption, they predict that the world today is facing a crisis of "human bombing", and that the "population crisis" will inevitably lead to an "ecological crisis," a "food crisis," and a "resource crisis," and that population growth has exceeded the carrying capacity of land and natural resources. These scholars warn that if this situation is not brought under control quickly and effectively, mankind will face a catastrophe as devastating as the explosion of the atomic bomb and the hydrogen bomb. They almost unanimously came to the conclusion that the root cause of these problems is the rapid population growth in developing countries.

In 1968, El Rich, an entomologist at Stanford University in the United States, published the book "Population Bomb", in which Professor Elrich asserted that it is foreseeable that in view of the explosive growth of the world's people, the earth will eventually be unable to support human beings. "The Population Bomb" begins with the words: "The battle to feed all humanity is over." In the 70s of the 20th century, thousands of people around the world will die of hunger. Elrich also wrote: "No one or anything can halt the dramatic rise in mortality in the world." ”

Since the publication of The Population Bomb, Professor Elrich has become a world famous and has sold millions of copies. It was soon translated into many languages and sold well in countries around the world, and it did achieve sensational results. It has caused people's panic about "human * bombing" and has had a great social impact.

Elrich is a pessimist through and through. His point is simple: he thinks that in a limited space, resources will be exhausted, and that there will be no mine if there is yours. He believes that due to the growth of human beings, human demand for food is increasing, and in order to increase production, a large number of chemical fertilizers are applied to the land, so that the organic matter is destroyed, and the land is desertified and barren. Other than that. Industrialization and urbanization have led to the encroachment of large amounts of arable land, reducing food production and making it more difficult to find food sources.

In 1974, Elrich once again predicted that before 1985, mankind would enter an era of resource scarcity, many non-renewable mineral products on which human beings depended would be on the verge of depletion, and human beings' devastating consumption of the earth's mineral resources would cause disastrous consequences for mankind. Human beings have caused damage to the natural world, causing air pollution to become more and more serious, and the ecological environment has been destroyed. He thinks. People come from the Third World, where the population is growing too fast, causing unemployment, poverty, resource depletion, environmental pollution, and so on. This is the real reason why the world is divided into poor and rich countries.

Society did not develop as Malthus and Elrich expected. As a scholar, Malthus was careful in his predictions of such a tragic prospect for humanity. With the same doubts, at first the article was published anonymously. Elrich is a big fan.

Malthus's "population principle" is essentially similar to Elrich's pessimistic view of "man*bombing", as Malthus argues. Humanity had to reach a balance of population through war, plague, famine. Elrich, for his part, directly advised the U.S. government not to provide any food aid to food-starved developing countries. Their doctrines and views have caused great panic among people, and then they are full of doubts and fears about the prospects for the development of human society. What is even more frightening is that some countries and political groups have absorbed and adopted their erroneous views and opinions and proposed to interrupt the development of the country. food and other humanitarian aid to the country. This trend of thought has hindered the healthy and harmonious development of human society in a certain historical period.

History did not go in the direction predicted by the "Population Bomb". United Nations statistics show that since 1961, the world's per capita agricultural production has continued to increase, with per capita agricultural production in developing countries increasing by 52 per cent. In some poor countries, living standards are improving, the number of people suffering from global hunger is decreasing, and the average life expectancy has increased to 67 years. Fertility rates around the world have declined significantly, from developing countries to fertility rates and developed countries. The new threat to humanity is not overpopulation, but population ageing due to declining fertility. In the 80s of the 20th century, according to the World Bank, after adjusting for inflation, the average price of metals and minerals fell by 20%, and the price of food fell by 50%, which means that the poorest people can also eat enough, and the main problem in more and more countries is not that people do not have enough to eat, but that they have to spend money to lose weight and treat various diseases caused by overnutrition.

In the 21st century, the world's population has reached more than 6 billion, and the number of people in 1968 increased by more than 2.5 billion when Bill Ritchie published his article "The Population Bomb". Time has also surpassed the age of the man* bombing predicted by Elrich. Why haven't resources been exhausted, and why haven't thousands of people starved to death, and why is human society not only not destroyed, but still moving forward. Not only that, but people are healthier and more affluent, infant mortality rates have dropped dramatically, and life expectancy has been greatly extended, especially in the third world countries that Professor Elrich is referring to. Of course, we have also seen that there are still some countries that are still suffering from wars, natural disasters or famine caused by wrong policies, but the growth rate of food production in the world has exceeded the rate of population growth, and it is a common consensus that the average population of the third world countries is now much more nutritious than in 1968.

The predictions of pessimists such as Malthus, Elrich, etc., failed.

The development of population has its own laws, and it is impossible for people as individuals to increase their height and physical fitness indefinitely due to genetic limitations, and their basic needs are a certain amount. The development of man as a population is also limited, and in terms of reproductive capacity, almost all plants and animals have the ability to reproduce indefinitely. Nature does not and cannot allow a species to exist alone. Malthus only illustrates the natural nature of infinite human reproduction, ignoring the social nature of human beings. Population growth will be constrained by social development. Once the growth of human beings affects the overall interests of human society, human beings themselves will rationally maintain a balance between population growth and resource supply. Humans are the rulers of the planet. In the 20 th century, the global population tripled from less than 2 billion at the beginning of the century to more than 6 billion at the end of the century, and if we simply reason by this multiple, by the end of the 21st century to 18 billion, and the population at the end of the 22nd century to 54 billion, in a few centuries, the earth will be full of people, and there will be no living space for other creatures, which is obviously impossible.

It is true that the population of the contemporary world is developing too fast. Anthropomorphists stress that it is also necessary to control population growth. However, they are wrong to blame the population growth of the third world as the cause of social poverty and backwardness, and they ignore that the reason why many countries in the third world are socially and economically backward and the people live in poverty is mainly because of the long-term imbalance in the development of the world economy and the plundering of colonies by the developed countries.

In fact, population development has its own laws, with the socio-economic and cultural development, the increasingly modern mode of production and lifestyle, since the 70s of the 20th century, the growth rate of the world population has begun to decline. Further declines are expected in the future. Human beings will increasingly consciously control population growth, the level of social productivity will continue to increase, and human society will develop in a more scientific and healthy direction. The arguments of "human * bombing" and "the end of the world is coming" are pessimistic. Lack of scientific basis.

American environmental expert Barry? "There is an intrinsic process in human society that adjusts the size of the population: an increase in the standard of living initiates population growth, if the standard of living continues to rise to a certain extent," Commanna said. Eventually, the population will stabilize. The main reason why the population of developing countries has not yet stabilized is that this basic condition has not yet been met. ”

With the development of the economy. People's incomes are increasing in various countries. According to World Bank statistics, the growth rate of the population tends to decline as income increases. The average population growth rate from 1990 to 1993 and their per capita income in 1993 for almost all countries. There is a tendency to associate low population growth rates with higher per capita incomes, and the linear straight lines in the graph represent this characteristic. As incomes grow, population growth tends to zero. (Each dot represents a country) (see figure).

The American economist Schultz, winner of the 1979 Nobel Prize in Economics, said: "There is also a lack of historical insight on the issue of population. We extrapolate global statistics and explain them to our own horror. Our explanation is that the poor reproduce like lemmings, only to end up destroying themselves. However, looking back at our own socio-economic history during the period of poverty, such a thing did not happen, nor does it occur in the context of population growth in poor countries today. Schultz added: "As incomes rise, parents show a preference for having fewer children and using quality over quantity, which Malthus could not have foreseen." ”

In September 1994, the director of the Worldwatch Institute in the United States, Lester Brown, was appointed to the United States. Dr. Brown published an article entitled "Who Will Feed China" in the American "World Watch". In the article, Dr. Brown argues that, on the one hand, with the increase in social population and the improvement of consumption structure, the demand for food will increase by 85% by 2030. On the other hand, China's food supply will be 20% lower by 2030 than in 1994 due to declining productivity, reduced arable land due to urbanization, and environmental damage caused by industrialization. Dr. Brown concluded that in the event of an increase in population and a decrease in arable land, the problem facing China would be a huge food shortage. By 2030, if China's per capita grain consumption level is calculated at 400 kilograms, the import of grain will reach 100 million tons, while the world's total grain exports will only be more than 200 million tons. At that time, not only will China not be able to feed itself, but the world will not be able to feed China.

Brown's specific analysis is that by 2030, China's population will increase from 100 million in 1994 to 1.6 billion, grain consumption will increase from the current 300 kilograms per capita to 400 kilograms per capita, and the total demand for grain will increase from the current 100 million tons to 100 million tons, an increase of 85%. At the same time, by 2030, China's grain planting area will increase from 100 million hectares in 1994. to 100 million hectares, a decrease of 47%. While yields could rise from the current 3,705 kg per hectare to 5,700 kg, total grain production would fall from the current 100 million to 100 million tonnes. 20% reduction. It is clear that from 1990 to 2030, food production will decrease by 20 percent on the one hand, and food demand will increase by 85 percent on the other, resulting in a gap between food supply and demand of 100 million tons. In this way, China's domestic grain production in 2030 can only be satisfied, and the rest of its needs will be imported.

Li Zhensheng, an academician of the Chinese Academy of Sciences and a researcher who won the country's highest science and technology award in 2006, said at the Boao Forum in 2005: "The result of our comparison is that Brown's inference is incorrect. It does not conform to the reality of China! First, the population growth rate is 1/3 slower than he expected, Brown predicts that the average annual population growth in the next 40 years will be 12 million, while the actual population growth in China in 2003 is only 7.61 million; Second, the rate of per capita arable land decline is not as severe as Brown expected, because the area of arable land in China measured by remote sensing is more than the traditional figure originally announced; Third, China's total grain imports and exports in the past 15 years have been basically flat, and the net import volume is only 100 million catties, which is equivalent to total consumption. Unworthy! ”

Researcher Li Zhensheng has been engaged in scientific research on wheat breeding for a long time, and has bred excellent genetic varieties with drought tolerance, dry and hot wind resistance, and resistance to a variety of wheat diseases, Xiaoyanmai No. 4, No. 5 and No. 6. By 1988, the cultivar of Xiaoyan No. 6 had a cumulative promotion area of 54 million mu. The output of wheat increased by 3.2 billion catties. He also established a new system of wheat chromosome engineering breeding, which overcame the two major problems of "monovalent chromosome drift" and "excessive workload for chromosome number identification" that had existed for a long time in the process of wheat utilization, and cultivated self-flowering and fruit-bearing deficient wheat. In addition, the new method of "missing body backcrossing method" was used to create rapid breeding of wheat heterogeneous lines, which laid the foundation for wheat chromosome engineering breeding.

At the Boao Forum, he confidently told the world: "Chinese people can feed themselves!" So for now. In the future, we believe that with China's correct policies and the development of science and technology and economy, we will be able to support ourselves! ”

Academician Yuan Lao, an agricultural scientist in China, is the world-renowned "father of hybrid rice". Hybrid rice is a world-class agricultural science and technology problem. Developed countries stepped in earlier and invested heavily. Academician Yuan Longping used scientific and innovative thinking and courageous exploration spirit to make a breakthrough in the research of hybrid rice in China. With the historical mission of "keeping everyone away from hunger", he mastered a variety of key technologies through trial and error, and achieved a major breakthrough in previous theories step by step with difficulty and perseverance. This scientific research achievement has enabled China to enter the world's leading level in the field of research and application of hybrid rice. After the promotion, it not only solved the problem of feeding the Chinese people, but also made outstanding contributions to world food security. Academician Yuan Longping said: "I now have three wishes: the first is to go to the third with Super Rice. Grade super rice research, in 2010 large-scale use. The second is to carry out the project of 'planting three crops and producing four', and within five years 80 million mu of grain will be produced on 60 million mu of land. The third wish is to promote hybrid rice to other countries and to the world. We are negotiating that within five or six years, we will be able to grow from the current 20,000 hectares to 10 million hectares, with an increase of two tons per hectare. Contribute to solving the problem of food shortage in developing countries. ”

In August 2005, during his visit to Hunan, Premier Hua praised him: "Yuan Longping's contribution is not only beneficial to China, but also to the world. Yuan Longping used his research to tell the world that China can not only feed itself, but also help developing countries solve the problem of food shortages.

Historically, between 1954 and 1964, the average annual increase in Asian rice production was %; The yield increase rate of new varieties is slightly higher than the population growth rate. The annual yield increase rate of Asian wheat hybrids increased from % to %. If enough land is secured to grow these new varieties and produce the same high yields, it will be possible to ensure that the areas with the fastest population growth will be able to feed the population.

From the 70s to the 80s of the 20th century, some developed countries in the West popularized high-yield cereal varieties and agricultural science and technology to parts of Asia, Africa and South America to help these countries and regions increase grain production. For example, "Mexican wheat" and "jasmine rice", after these varieties and technologies were popularized in some countries, grain production increased significantly, and history is called the first "green revolution". Since the Green Revolution, world food production has grown much faster than the number of people. China's hybrid rice is also an outstanding representative of the first Green Revolution period.

American economist Schultz noted: "In 1933, before the introduction of hybrids, corn was planted in the United States on an acre of 100 million acres. Production was 2.4 billion bushels. By 1987, corn was planted on only 100 million acres. But production amounted to 100 million bushels. In 1987 compared to 1933, although the acreage was reduced by 100 million acres. The output is more than three times that of the case. In addition, the decline in the cost of corn production, the decline in the cost of raising livestock and poultry products, and the sharp increase in consumption surpluses, etc., are all fruits of the green revolution. ”

The breakthrough of the "Green Revolution" in agriculture has comprehensively promoted the development of various important factors of modernization. Food security remains a "top priority". In the process of future development, human society will also face a series of problems such as water shortage, desertification, and consolidation of cultivated land. However, these problems that have arisen and encountered in the course of development in developing countries will certainly be gradually resolved in the course of development.

Humans have lived on the earth for three to four million years before they know that the shape of the earth is oval. This may seem absurd to modern people, but it is a fact. Some organisms, in fact, many organisms, even all living beings except humans, have lived on the earth for millions of years or even longer without realizing this. For example, trilobites have been asleep on the earth for 700 million years and do not know what the earth is.

The specific position of the Sun is on the Orion spiral arm north of the Milky Way, and the volume of the Sun in the Solar System accounts for about 99.8%, and the volume of the Sun is about 1.3 million times that of the Earth. What is the concept that the sun is 1.3 million times larger than the earth? If the volume of the earth was as large as the sun, and the area of the five continents and four oceans were proportionally expanded to the size of the sun, perhaps human beings would still live independently in different closed areas. Perhaps Columbus still did not discover the New World until today, and the development of human history is certainly not as fast as it is now.

In addition to going to the moon, human beings have even been to the nearest planet, Venus (also known as the Morning Star or Chang Gung Star in ancient China, which is the third brightest celestial body after the Sun and the Moon. When the sky is bright, the star will gradually disappear as the sun rises. Haven't been there either. Moreover, judging from the current human exploration results, among the nine planets and their moons in the solar system, only the earth adapts to the survival and development of organisms and human beings.

Some say it's possible to go beyond the solar system in search of new human settlements. That's a great idea, but it's too difficult to implement at the moment. It's just a fantasy. Of course, if humanity does not perish for a long time to come. Moreover, human science and technology are still developing and improving, and this idea can also be realized by Zhou Yuna. Take Centauri A, the closest star to our solar system (and of course to Earth), which is our neighbor star, which is about 4.2 light-years away from us, how can humans reach such a long distance? It takes more than 4 years for light to travel 300,000 kilometers per second, and almost all of these distances of more than 4 light years are ethereal space, and there is no rest transit station in between. Some friends here will say that due to technical reasons, there will be errors, we give a discount, 2 light years, which is not a lot! Also, some people always like to use this analogy: what is said to be thick or as many as the stars in the sky, in fact, this is not true, the stars in the sky are very thin and thin. Otherwise, we will really be able to take the moon, but this is very dangerous, and it is not good for the survival and development of living things! As for the reports that humanity can reach Centauri A in no more than 100 days through the four-dimensional space, this great ambition will remain on paper for mankind for now and for a long time to come. If humanity needs to travel farther to the stars, then the difficulty is even greater.

At present, although human beings can be said to dominate everything on the earth, human beings are still insignificant to the earth and even to this vast and boundless universe. The Milky Way is currently about 1,021 meters wide, which means that humans live in the Milky Way galaxy about 100,000 light-years wide. You can think about it, what kind of concept is 100,000 light years, light travels at a speed of 300,000 kilometers per second for 100,000 years, the distance is really incredible, but this is only the Milky Way, what about extragalactic galaxies?! Isn't it even bigger? According to the most authoritative data, the length of the universe that can be observed by humans is about 1027 meters. Obviously, is there anything that humans haven't observed? Think about it again, aren't humans and the earth too small for this universe?

In the vastness of the Milky Way. A single star that moves independently accounts for only 1/4 of the total number of stars, while binary or clustering star systems abound in the Milky Way. Of these one-quarter of a single star system, there are even fewer stars with planets like the Sun. There is only one in about 100,000 stars, and the reader can be told for sure that the closest star to humanity, Centauri A, is a binary star system (two stars orbiting each other, but no planets), and even if our spacecraft or space shuttle could get there, there would be no place to rest.

In the vast universe, there are shining and dazzling stars that glow and emit heat, but what about planets? Not only are they very few, but they are also very small in terms of quality and volume. It can be said that stars are one of the most basic and primary roles in the universe. Ours is a universe where we can see that the universe is a star, not a universe of humans or planets, and the stars are the protagonists of this universe. Of course, as mentioned above, dark energy is the protagonist of the universe, so even from the perspective of dark energy, it is not an environment suitable for human survival and development.

From the astronomical knowledge that mankind has obtained so far, we know that not every star system in this universe has an earth, and there is an environment like the earth that is suitable for human survival and development. On the contrary, in almost every star system in the universe, there is hardly a Earth, and almost none of them are as adaptable to the environment for human survival and development as the Earth. If every star were like the sun, there was a planet around it that had life like the Earth. Then the survival resources of human beings are not scarce, or the radius of the earth of human beings is very large, the larger the living resources of human beings are relatively not so scarce, in fact, the universe and various celestial bodies did not appear for human beings. The finite nature of the resources that God has given to human beings for survival. This determines or restricts the survival and development of human beings, and it can be said that in the vast universe, human survival resources are extremely scarce. The scarcity of human resources is the root cause of human catastrophe. It can also be said that the scarcity of human survival resources is the greatest disaster for mankind. It is the root cause of all human disasters.

Take the solar system in which humans live, for example, and humans inhabit the earth. Its survival and development depend on the sun. The survival and development of human beings is inseparable from the star of the sun and the planet of the earth revolving around it, and the distance between the two should be appropriate. The state of the two should be at least relatively stable, and at the same time, there needs to be proper temperature, gravity, moisture, sufficient sunlight and the atmosphere to prevent external radiation from harming human beings. We can imagine that if there is life in the universe in which human beings live in such a three-dimensional space and one-dimensional time (in fact, the two are closely linked and inseparably integrated), then it must be like the relationship between our sun and the earth. First of all, there must be a star that emits light and heat, secondly, there must be planets revolving around it, and finally, the planet's environment must also have the conditions for the survival and development of living things. It's a pity that only one out of about 100,000 stars will have something like the Sun. What is the concept of one in 100,000? Only one of the 100,000 stars that can move alone and have planets like the Sun is even less likely than winning a lottery ticket. What's even more frustrating is that the stars are so far apart, with the average distance between stars in the Milky Way being about 6-7 light-years. Therefore, it can be said that in the universe, resources for human survival and development are extremely scarce.

"At the end of the 20th century, the United States conducted an experiment code-named 'Biosphere 2' to study whether humans could live in a sealed artificial ecosystem for a long time. The experiment built a steel-framed glass seal, covering an area of more than 13,000 square meters, which was carefully designed and arranged with woods, meadows, pastures and 'artificial oceans' to feed pigs, chickens and other animals, and the entire installation cost more than 200 million US dollars. In 1993, eight scientists joined the group, and they planned to conduct scientific research while farming and breeding. According to the plan, the ecosystem should be able to maintain ecological balance, oxygen levels can be maintained, food can be self-sufficient, and scientists will live in this sealed body for 2 years. But after more than a year, the oxygen level in the seal has dropped from 21 percent to 14 percent, and the harvest has failed, forcing people to eat the grain. Under these circumstances, personnel were forced to withdraw early, and the Biosphere 2 experiment was declared a failure. "The failure of this experiment shows that human beings cannot survive long without the earth's environment. At present, although humans have built some space stations and left human footprints on the moon, this is still a great distance from the environment in which humans will live and live for a long time.
