How many people live on Earth? Probably, every person sometimes asked such a question. The growth of the population on our planet has always occurred: climate change, drought, famine, predators, the struggle between the tribes only slowed down the demographic process.
6.7 billion people - this is the figure that indicates how many people live on the Earth at the moment, which is 6% of the total population (107 billion) that ever walked on its surface. Of course, this number is approximate, since it is difficult to imagine what happened in ancient times, and even more so to calculate.
How many people can "fit" on Earth
If we imagine how many people live on the Earth, it can be understood that with the growth of the population, the population's needs also grow, and the lack of control over the demographic process can lead to an ecological catastrophe: epidemics, hunger, crime, 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 in weight units of measurement, and found that obesity, which affects half of humanity, not only harms a particular person who consumes a large amount of food, but also the planet as a whole, increasing the load on it.
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 densely populated country is China, whose government has already begun to take measures to slow the process of overpopulation of the country. In second place - India and the US, inactive in the demographic issue. It is India, according to the UN forecasts, in the near future will become the leader in population growth, the amount of which in 50 years will reach 1.5 billion people on Earth.
How many years has this rapid demographic progress, which, in addition to damaging effects on the ecosystem, breaks the fate of people, forcing them to leave their marginalized lands due to climate change, lack of water and food? Migration occurs due to disturbance of the natural habitat. In 1996, the UN attempted to calculate how many people lived on the Earth and how many people tried to leave the ruled territories. The results were shocking: the number of environmental migrants was 26 million people; are going to leave their country 137 million.
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 today, it is required to understand the causes of increased fertility, 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, which have high infant mortality and short life expectancy, the birth rate is very high, so almost all families there have many children. The aid given annually to the poor in improving their standard of living, however paradoxical it may sound, only worsens it. That is, there is an effect not on the causes, but on the effect. In addition, poor countries that exist on subsidies from richer countries get used to them and stop any attempts to improve the situation of reducing the birth rate.
High standard of living - low fertility
With a high degree of material prosperity, the need for fertility decreases, the death rate decreases, and the average life expectancy increases. As an example, we can consider Thailand, where for 25 years (from 1965 to 1990) the standard of living has grown almost 12 times, and the birth rate has sharply decreased. Such dynamics are observed in most countries that have set foot on the path of industrialization.
With the growth of the living standard of the population and a well-developed pension system, children cease to be an economic priority for parents, as occurs in traditional society. The number of families with two or more children is decreasing; many parents have enough and one child. And the decision to give birth to a baby is taken deliberately, taking into account all the pros and cons, as the individualistic claims to one's own happiness become the most important in modern society. Therefore, many couples remain childless, and this directly affects how many people live on the Earth.
According to conservative projections, by 2075 the population on the planet will be about 9 billion people, then this figure will decline.
The assumption is made of how many people on Earth will be, the following reasons:
- Growth in the well-being of people in 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 size of the world's population is certainly great. Apparently, therefore, more and more often catastrophes began to occur on it, the number of which has increased threefold in comparison with the last century. How many people lived on Earth? How many more will be born? How many people are on Earth today? Perhaps the planet itself regulates the population and tries to restore the natural balance, freed from its overabundance.
