A recently published scientific paper in the journal Science reported that the Earth there are high chances for the year 2100 to become home to 11 billion people. Study was conducted by the University of Washington expert Adrian Raftery. It should be noted that the new figures are higher than earlier forecasts of experts about 2 billion people.

The scientist also points out that the growth of the world population to 9 billion people will be the peak point of growth, after which the rates may be reduced.

“Observations show that over the next 20 years (or so) the world’s population, which currently stands at 7 billion people, will grow to 9 billion, after which it will be noticeable slowdown of growth” – indicates Adrian Raftery said in a statement.

“In this study, we can give 70 percent to the fact that the world’s population does not stabilize in this century.”

The study shows that most of the population growth will be noticeable in Africa. It is noted that by the end of this century, the number of people on this continent will increase by four times and will be 4 billion people. Population growth in the Asian countries will also be very large, and, given all the current circumstances, in 2050 the population of these countries will be 5 billion people, and then is expected to decline.

In turn, the population of North America, Europe, Latin America and the Caribbean will be a total of 1 billion people, or perhaps even less.

Scientists warn that with increasing number of the world’s population, more and more people face the challenges of climate change, the growth of infectious diseases and poverty. Therefore the rational thing would be to take action against the birth rate, especially in Africa ( remember Isaac Asimov).

According to Adrian Raftery and his colleagues, this problem can be solved, for example, higher-quality educational methods of girls and women, as well as providing better access to contraceptives.
