World’s population evolution

Is a known fact that the world’s population is now on a serious growing trend. In Antiquity and Middle Ages the life was very hard and the new born mortality was extremely high, while the life expectancy was small.

Things started to change since the 18th century when the Agricultural and Industrial Revolutions improved the life quality. The life expectancy of both children and adults improved dramatically and the world’s population started to grow towards unprecedented levels.

In Europe, at the beginning of the 18th century lived nearly one hundred million people. By the end of the same century the Europe’s population nearly doubled, and by the end of the 19th century it doubled again. The new discoveries and the development of medical systems also contributed to a considerably growth of the population all over the world.

Currently is it estimated that the world’s population is around 6,893,500,000 people. The annual births worldwide are now 140 million and the number of deaths is around 57 million per year. It is expected that the number of deaths to increase, while the number of births to remain constant. This will result in a small decline of the population’s growing rate which now is 1.1% per year. It is estimated that by 2050 the population will reach more than 8 billion people.

The most populated countries in the world are China with around 1.3 billion people, India with 1.2 billion inhabitants and United States with only 310 million people.

Many scientists say that the intensive population growth has its share of guilt in current environmental problems. They say that the global warming, pollution and high levels of atmospheric carbon dioxide were also influenced by the population growth.

A large population needs more resources and could threaten the entire ecosystem. It is a known fact that the natural resources are quite limited and many fear that at one point these resources could disappear putting to a survival test the entire human race.
