By 2100, the world population could reach 11 billion people

According to the statistical analysis, the Earth's population could reach 11 billion by 2100. This is 800 million more than anticipated in 2011. Basically, it is because the birth rate in Africa has not fallen as quickly as planned. According to the UN, by October 2011 the world population reached 7 billion, which is a surprising amount, compared with 5 million in 8000g. BC and 1 billion in 1805.

 

The huge increase in population due to the advent of mega-cities, which are due to problems with the environment and overpopulation.

Now Africa's population is 1.1 billion and could reach 4.2 billion in 2100. Along with the countries of the southern continent, suffer from overpopulation, countries such as China and India, as well as selected megacities United States and Europe.

In the world as a whole do not tend to have a positive demographic changes. Europe at the same time may face a decline in the population, as of today the death rate exceeded the birth rate. European average family has 1.3 children, a high level of disease, drug abuse and other social problems takes away so many lives, that the birth rate has no time to cover such losses.

Already, many cities and countries suffer from overpopulation, war, lack of food, drinking water and other essential resources for life.

The new analysis used in the studies, contains a more complex method for estimating life expectancy, fertility rates and population. The model shows that the population is likely to reach 9 — 13 billion by 2100. The UN estimates that at the end of the 21st century the world population could reach 7-17 billion.

The findings suggest that it is necessary to make special efforts to curb population growth in Africa. New demographic data suggest the need to raise the standard of living and birth control in third world countries. As you know, the higher the standard of living in the country, the better educated and more prosperous its people, and this leads to the birth control within acceptable norms.
