How many people can the planet withstand? What is the population of the earth?

You may think that the current population of 6.5 billion people on Earth is already overwhelming the planet, but according to the calculations of scientists in the United States and Romania, the maximum limit of the Earth's population is 200,000 times the current number of people on Earth! But scientists say this is just a theoretical figure, and it must be based on the premise that humans can solve food shortages with high-tech methods. Once the obstacle of "shortage of survival necessities" is overcome, the population of the planet will reach a maximum of 1,300 trillion!

At that time, humans on Earth will be as dense as ants, and most people will be crammed into 2,000-story skyscrapers everywhere, living in an orderly manner like prisoners, rarely seeing the sun again.

According to reports, the global population will rise from the current 6.5 billion to 9 billion by 2050, but according to the research of Dr. Vioriel Badi Scoo, a scientist at the University of Arts in Bucharest, Romania, 9 billion people are far from reaching the limit of what the planet can sustain. Dr. Buddy Treasurer declares in the forthcoming issue of the journal International Journal of Global Energy Issues next month that according to his calculations, the earth will eventually be able to sustain 200,000 times as many people!

As early as 1964, Professor Franklin claimed that as long as the heat obtained by the earth (including the heat generated by the earth's organisms and the solar energy absorbed by the earth's surface) can be kept in balance with the heat it emits, then the earth will always be in a state suitable for human habitation. If there are too many people on the planet, then like a crowded, stuffy party, there will be too much heat to be generated for the planet to bear. Through calculations, Professor Flemlin concluded at the time that the maximum population limit on Earth would be 600 million people.

Dr. Buddy Treasurer and Richard Cascart, geographer in Bubank, California, USA, re-evaluated Professor Frommlin's research using more advanced thermodynamic models. Scientists hypothesize that each person emitting 120 watts of heat, and when the average temperature of the earth's surface rises too high, it will no longer be suitable for human habitation, according to calculations, Badi Scu and other scientists finally declared: Under the condition that the earth's temperature is not too hot, the limit number of people that the earth can carry should be 1,300 trillion people, which is 200,000 times the current population.

Scientists admit in their research reports that this limit of the earth's population is only a "theoretical number", and that the earth's population will face a serious shortage of living resources before the earth's population reaches this limit.

Dr. Buddy Treasurer wrote: "In the not-too-distant future, the shortage of food and necessities will become a critical issue, but with the development of human civilization and science and technology, the shortage of food and other necessities will continue to improve." ”

Scientists say that in terms of living standards, if every person on the earth can enjoy the diet of ordinary people in developed countries, the maximum capacity of the earth is only 2 billion people; And if we are based on the daily standard of minimum food necessities, the earth can support 12 billion people. Many scientists, such as Edward, a social scientist at Harvard University. Wilson believes that the planet has a maximum capacity of about 9 billion to 10 billion people.

Russia's Morning Post reported that many scientists believe that 15 billion people are the limit of the planet, and unless immediate action is taken to control the rate of growth, the earth's resources will face catastrophe. The global population will reach this staggering number by 2100. Edward Wilson, a social scientist at Harvard University, believes that the maximum carrying capacity of the planet is about 9 billion to 10 billion people.

The Earth's population is 7,262,310,000. There are hundreds of millions of people in the world. According to the U.S. Census Bureau, the global population exceeded 7 billion on March 12, 2012, while the United Nations Population Conference (UNDEMORATE**) showed that the global population reached 7 billion on October 31, 2011, and 7.1 billion in 2014.

In 2016, the world's population reached 7,262,306,342 people, and according to estimates from the U.S. Census Bureau, as of January 4, 2013, there were 100 million people in the world.

Sustainable development

Negative population growth and population aging go hand in hand and interact with each other. First, negative population growth will lead to labor shortages. On the one hand, labor efficiency will decline accordingly, affecting the process of economic development; On the other hand, more countries have introduced deferred retirement policies, which have squeezed out job opportunities, affected fertility intentions, and entered a vicious circle.

Second, the accelerated aging of the population will increase the burden of the state on the elderly population, which is not conducive to the equalization of social security. Finally, even if the total population reduction will reduce the burden on resources and environment, with the continuous escalation of personal consumption, negative population growth will still affect the sustainable development of resources and environment.

As of 2020, the world's population totaled 7,262.31 million.

The world's population continued to grow after the Black Death and the Great Famine in Europe in the 50s of the 14th century, and there were about 100 million people in the world at the time of the collapse. Subsequently, due to factors such as war, the growth rate was sometimes fast and sometimes slow. After the end of World War II, from the 1950s onwards, the rate of world population growth accelerated markedly – exceeding each year – due to reductions in factors that led to slowing population growth, such as war and famine.

This state lasted until 1970. In 1963, the world's population grew and reached an all-time high. Subsequently, with the development of the economy, people's conception of fertility changed, and the population growth rate gradually declined.

In 2011, the world population growth rate was about: The world's population is expected to reach 8 billion by 2040.

Current projections all point to a sustained increase in the world's population for decades before the hailstorm, but it is difficult to estimate the decline in the birth rate and other factors make it impossible to derive specific figures, only that the world's population will be between 7.5 billion and 10.5 billion in 2050, depending on the rate of decline in the birth rate.

In the long run, it is estimated that the world's population will stop growing and decline slowly around 2050-2150. At the same time, some analysts have expressed concerns about whether population growth can be sustainable.

As of 2020, there were 7,262.31 million people living in the world. The world's population grew in the 50 years of the 14th century, when it was about 100 million people, after the Black Death and the Great Famine in Europe. Subsequently, due to factors such as war, the growth rate was sometimes fast and sometimes slow.

After the end of World War II, from the 1950s onwards, the rate of population growth in the world was due to the reduction of factors that led to a slowdown in population growth, such as war and famine.

At present, the total population of the world has reached 100 million. For every billion people added, the time required was shortened from 100 years to 10 years. The world's population is expected to reach 9.5 billion by 2050.

As of 2021, the world's population is about 7,585.2 million.
