The world’s population is reaching 8 billion and that is not good news for anyone. The world had taken thousands of years to reach 5 billion, which happened in 1987. It has taken just 32 years to close in on 8 billion. The explosive growth had made the world leaders worried as United Nation had created World Population Day in 1989.
This day was created to raise awareness about the problems created by overpopulation. 11 July is observed an annual holiday. As of today, the world’s population has reached 7.7 billion. Just think of a second, 7.7 BILLION. If you start now and count 7.7 billion in terms of second, it will take you to the year 2263. The world population will not stop here.
It is estimated that at the end of 2050, the world’s population would increase by another 2 billion. We are having so many problems with the current population, just imagine the chaos with another 2 billion people. However, some areas have lost population as well. UN has said that since 2019, 27 countries/areas have lost about 1% population.
The main reason for the population drop is the lower levels of fertility, especially in countries like China and Japan. In fact, the global fertility rate has fallen. In 1990, the rate was 3.2 births per woman which has dropped to 2.5 births in 2019. This declining projection will continue. These shrinkages are dwarfed by the population booms in other countries. The most prominent area is the sub-Saharan Africa, whose population is estimated to double by 2050.
According to a 2018 study, nine countries– India, Nigeria, Pakistan, the Democratic Republic of the Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States—will constitute up more than half of the projected growth of the global population between now and 2050
