Once, at the time of the Roman Empire, it was 50 million. In 1800, the population reached 1 billion in 1950 were 2 billion and a half, and today we are 7 billion in 2050 predicted that the number of the earth's population to reach 9 billion. However, the road to survival, which lasted 20 years, seems to be coming to an end.Demographic proportion of the population is in constant decline. After the industrialized countries, the number of births decreased even in developing countries, which have recently begun to enjoy a little phenomenon. Percentage of births across the globe, which in the 50s was 5-6 children per couple is sitting on 1 or 2 children per family.
Fertility specialists have predicted that between 2020-2050, the percentage of births in the world, interrupting the addition of earth's population, which is projected to reach 9 billion people, will begin to diminish. The world scenarios sadder risked unleashing the high proportion of demographic, will save himself.
She has photographed this phenomenon, which recently has been considered seriously by the researchers, it is the British magazine "The Economist". The first to cut the proportion of rich demographic West and more developed. Now this phenomenon is also present in other countries of the world such as Brazil, Indonesia, parts of India and China, where a couple is not allowed to have more than one child. If the UK, which was the cradle of the industrial revolution, it took 130 years to reduce the number of children from 5 to 2 or no, in South Korea sufficed only 20 years, from 1965 to 1985. If Europe and the United States average was two children per family, today the third world women can bring to life three children while their mothers had six or seven children. In some other countries of the world, the percentage of births decreased even more: if in 1984, Iran was average seven children per family in 2006 and nu reduced to 2 children per family.
According to the magazine "The Economist", the reason for which is reduced percentage is a single demographic: "When people get rich, households reduced". Agriculture was very important for the livelihoods and the main source of income of the population of Africa and the rest of the world needed more family members to evolve. Six children in the family once needed to assist parents in planting land. Unlike the past, today many families new middle class of Brazil, China, India, a child can be a joy, concern, or obligation, but not safety, or help to survive. Macroeconomic analysts uncovered moment when the situation began to change: the number of births decreased when revenues were down from hundreds of dollars to 1000 or 2000 dollars per family. N In 1970, the birth rate was 2.1% in 24 countries, while today it has spread to 70 others. However the fact that more surprising is that such a thing is observed in the African continent.
The low number of children per family passage from poverty to the middle class, from an agricultural society, to the modern and complex. They have accompanied the transition of many factors: education, use of kontaceptivëve and great prosperity (one study estimates that in 90 years a quarter of births in developing countries were unwanted pregnancies).
The main article of the magazine " The Economist " called: "Look how will vetëzgjidhet overpopulation problem." Even this article is accompanied by a notice, will not be enough just to reduce the number of births to 'cure' the planet by other problems, such as global warming and the need for human resources needed. Should poor countries, which are on the path of prosperity and reducing the number of births not to imitate the rich Western countries in their economic growth. Today the poorest Africans produce 0.1 tons of CO2 per year, compared with 20 tonnes per capita for every American. So if you copy the consumption and pollution of the industrialized world, the consequences would be devastating for the planet. If it is true that the world is saving himself with a demographic decline, they need people to help with arrangements of governments, economies and technologies of slowing greenhouse. Being that we are adding enough, the time has come to end this phenomenon.
THE HIGH NUMBER OF BIRTHS NOT ONLY DISTURB THE RICH WEST, BUT ALSO IN MANY DEVELOPING COUNTRIESIF IT IS TRUE THAT THE WORLD IS SAVING HIMSELF WITH A DEMOGRAPHIC DECLINE, THEY NEED PEOPLE TO HELP WITH ARRANGEMENTS OF GOVERNMENTS, DEVELOPED TECHNOLOGIES, AS WELL AS SLOWING THE GREENHOUSEBEING THAT WE ARE ADDING ENOUGH, THE TIME HAS COME TO END THIS PHENOMENONSIX CHILDREN IN THE FAMILY ONCE NEEDED TO ASSIST PARENTS IN PLANTING LAND, NO LONGER THE CASE TODAY
