According to statistical analysis, the world’s population may reach 11 billion by 2100 This is 800 million more than supposed in 2011 Basically, this will happen because in Africa’s birth rate has not fallen as fast as planned. By According to the UN, by October 2011, the world’s population reached 7 billion. This is an amazing amount compared to 5 million in 8000. BC. and 1 billion in 1805
The huge population growth is due to the emergence of megacities, due to who have problems with ecology and overpopulation. Now Africa’s population is 1.1 billion and may reach 4.2 billion in 2100g. Along with the countries of the southern continent, from overpopulation countries such as China and India suffer, as well as individual million-plus cities of the USA and Europe. Moreover, the world as a whole does not there is a trend towards positive demographic changes. Europe at the same time may face a decline in population, since today the mortality rate exceeds the level birth rate. The average European family has 1-3 children, while high level of diseases, drug addiction and other social problems kills so many lives that the birth rate simply does not have time cover such losses. Already today many cities and countries suffer from overpopulation, wars, lack of food, drinking water and others important resources for life. New analysis used in research contains a more sophisticated assessment method life expectancy, birth rate and population. Model shows that the population is likely to reach 9 – 13 billion to 2100g. According to UN estimates, at the end of the 21st century, the world’s population may make up 7-17 billion people. The data obtained indicate that special efforts are needed in order to curb population growth in Africa. New demographic data say that it is necessary to improve the standard of living and birth control in third world countries. As known, the higher the standard of living in the country, the more educated and well-off its people, and this leads to birth control in acceptable norms.
