What happens when the Earth's population will stop growing?

Recently we wrote about the fact that the Earth's population is aging. All anything, but that happens for the first time in the history of mankind. Compared with 1960, the year the birth rate has decreased significantly. Today, people older than 65 years on the planet more than the children under five years of age. The decline in fertility is particularly noticeable in Europe. If it goes on, in the future, the most populated continent of the planet will be Africa. And the most popular religion in the world already in 2050 will be to Islam. But what would happen if the Earth's population will stop growing?

How many people live in the world today?

Throughout the history of our civilization, the world population grew very slowly. In 1800, the number of people on the planet is less than 1 billion people. In 1950, Earth is home to 2, 5 billion people, and today, as you know, we have almost 7, 7 billion.

Such a sharp rise in fertility mankind owes to scientific progress. Medicine, sanitation, mass production of food made incredible. However, ever since it can not continue. According to United Nations estimates of the Organization, the growth of the world's population will stop around 2100. By that time, according to forecasts, world population will reach 11 billion people. See also: The world really is overpopulated?

Mankind has experienced a decline in population. Only one plague at the time claimed the lives of nearly 200 million people. But this time things will be different. The reason for the coming demographic transition will be a decline in fertility. Access to food, income growth and education for women is strongly influenced by the situation.

How many people will be in the world in 2100?

Despite the error in the calculations of demographers, in the next 100 years the world population will peak. Many experts point out that the most populous region in the world in the future will be Africa. But the most important thing is that the Earth's population will age.

UN figures show that for eight decades, from 2020 to 2100, the number of people aged 80 will increase from 146 million to 881 million; Around the same time, the average age will increase from 31 to 42 years old.

As our culture will change in the future?

Thus, according to scientists, in the future we will be faced with the crisis of the pension system. Moreover, over time the structure of family life to change much. Number of persons in the family is becoming less - children will have fewer brothers and sisters, parents will invest more resources in each child.

In addition, many sociologists have noted that the culture is moving toward reducing the number of people in the family and not the other way around. For example, in Africa, family ties are expanding due to cohabitation with cousins ​​and other relatives. In many cultures, people will prefer cohabitation like the birth of a large number of children. In addition, those who have not got their own or family or people, who have little family will strive to expand the social circle.

Yet such assumptions scientists expressed without taking into account the effects of climate change. Meanwhile, in some Western countries there are civil movements, disclaims having children because of global warming. Despite the fact that the number of supporters of such a sharp rejection of procreation today is small, it is possible that in the future it will affect the population.
