How many people live on earth? Probably, each person sometimes asked a similar question. Population growth on our planet has always happened: climate change, drought, famine, predators, the struggle between the tribes just slowed down the demographic process.
6.7 billion people - this is a figure that indicates how many people live on Earth at the moment, which is 6% of the total population (107 billion) who has ever walked on its surface. Of course, this number is approximate, as it is hard to imagine what happened in ancient times, and even more so to count.
How many people can "fit" on Earth
If one imagines how many people live on Earth, one can understand that as the number grows, the needs of the population grow, and the lack of control over the demographic process can lead to an environmental catastrophe: epidemics, famine, crime growth, poverty.
Many people often ask the question: how many people Earth can stand? More than lives today. But the planet is not dimensionless, as well as her patience and endurance. The German Foundation for population, it was estimated that every minute the number increases by 155 people. In the total annual number that can be represented as the emergence of yet another Germany. How many people on Earth can "fit" depends on the consumption of strategic resources of the planet, what's in the lead, of course, the Americans. If all the residents were consuming the Earth's resources with the same appetite, then the environmental limit of endurance would be left in the past. With the conduct of a frugal lifestyle of Brazilian Indians, the planet would be able to feed 30 billion people.
Scientists theoretically tried to weigh how many people on Earth are in weight units, and found that obesity, which affects half of humanity, harms not only a particular person who consumes a large amount of food, but also the planet as a whole, increasing its load.
Examples of population density
Surprisingly, 7% of the total area of Land close to 70% of the population. In one only to Moscow per square kilometre account for about 13 000 people, while Canada – the whole country is empty. Conventionally, it can even be called deserted, because in certain districts in every canadian has the order of 100 square kilometers. Thus, the uneven distribution of people on the planet is an extremely important question on the minds of many citizens.
The most populous country is China, whose government has already begun to take measures to slow down the process of overcrowding the country. In second place - India and the United States, inactive in the demographic issue. It is India that, according to UN forecasts, in the near future will become the leader in population growth, the number of which in 50 years will reach 1.5 billion people on Earth.
How many years has lasted such rapid demographic progress, which, in addition to the detrimental effect on the ecosystem, breaks the fate of people, forcing them to leave the inhabited lands due to climate change, water and food shortages? Migration occurs due to disturbance of the natural habitat. In 1996, the UN made an attempt to calculate how many people lived on Earth and how many people tried to leave the inhabited lands. The results were shocking: the number of environmental migrants was 26 million; 137 million are going to leave their country.
Causes of growing demographic growth
A number of studies have shown that the main population growth occurs in countries with a low standard of living.
To answer the question: how many people are on Earth right now, it is necessary to understand the reasons for the increased birth rate, especially in countries with a low standard of living:
- the biological law of struggle for survival, implemented on a subconscious level and consisting in the opinion: the less the chances of the offspring, the higher the birth rate
- procreation, supported by economic considerations: the number of children in the family ensures that the planned number of workers, which depends on ensuring old age disabled parents
- social-psychological factors: customs, traditions, religious dogmas, prevailing for centuries, taking into account economic and social aspects of life at different stages of development.
In poor countries that have high infant mortality and short life expectancy, the birth rate is very high, so almost all families have large children. The aid that is allocated annually to the impoverished population to improve their standard of living, however paradoxical it may sound, only worsens it. That is, there is an impact not on the causes, but on the consequence. In addition, the poor countries that are subsidized by richer countries get used to them and stop any attempts to remedy the situation of reducing the birth rate.
High standard of living - low birth rate
With a high degree of material well-being, the need for fertility decreases, the mortality rate falls, the average life expectancy increases. As an example, we can consider Thailand, in which over 25 years (from 1965 to 1990) the standard of living has increased almost 12 times, and the birth rate has decreased dramatically. Such a dynamics is observed in most countries that have stepped on the path of industrialization.
With rising living standards and a well-developed pension system, children are no longer an economic priority for parents, as is the case in traditional society. The number of families with two or more children decreases; many parents have enough one child. Moreover, the decision about the birth of a baby is made deliberately, taking into account all the pros and cons, as individualistic claims to their own happiness become prevalent in modern society. Therefore, many couples remain childless, and this directly affects how many people live on Earth.
According to conservative projections, by 2075 the population on the planet will be about 9 billion people, then this figure will decline.
Due to the assumption of how many people on Earth will be, the following reasons:
- Growth of well-being of the population of developing countries.
- The rapidly growing level of education in developing countries, which dramatically increases the possibility of growth of welfare of the population. Income qualified specialists much more than the uneducated people. A high level of education reduces the need for many offspring.
- The steady growth of urbanization (movement of people from rural areas to the city) all parts of the world. The higher the percentage of urban residents, the higher the level of education of the population and, accordingly, its revenues. And this, again, affects the reduction of fertility.
- Increasing mortality from epidemics and AIDS infitsirovanija for 20 years, more than 60 million people and claimed the lives of more than 22 million. Especially are suffering from AIDS people in poor countries experiencing a catastrophic lack of General health culture, hospitals and medicines.
Today's population of the planet is certainly large. Apparently, therefore, catastrophes began to occur more often on it, the number of which increased by 3 times compared with the previous century. How many people lived on Earth? How many more will be born? How many people are on the earth today? Perhaps the planet independently regulates the population and is trying to restore the natural balance, releasing from its oversupply.
