Based on current projections and some margin of error, it looks like we’re fast approaching $8 billion. human limits, and we can reach it “any day,” according to the Wall Street Journal.
“This year, World Population Day is celebrated in an important year, when we await the birth of the eighth billionth inhabitant of the Earth. It is an opportunity to celebrate our diversity, to recognize our common humanity and to recognize the health achievements that have increased life expectancy and dramatically reduced maternal and child mortality, UN Secretary-General António Guterres said in a recent statement. “At the same time, it is a reminder of our shared responsibility to care for the planet and a moment to reflect on where we are still falling short of our obligations to each other,” he added.
UN forecasts also state that by 2030 world population may increase to 8.5 billion by 2050 – up to 9.7 billion, and in 2100 – up to 10.4 billion Due to this huge change, by 2023 India will overtake China to become the most populous country on the planet.
Meanwhile, the population of developing countries will increase significantly. According to the UN, more than half of the projected increase in population by 2050. will be concentrated in just eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and the United Republic of Tanzania.
However, other forecasts predict a slightly different future. in 2020 A major study published in the journal The Lancet suggests that the world’s population will continue to grow over the next few decades, and by 2064, will reach a peak of around 9.7 billion people, and in 2100 will decrease to 8.8 billion If true, it will be the first time the world’s population has declined since the 14th century. middle, when the Black Death was raging.
In both of these scenarios, sub-Saharan Africa will experience massive population growth, while the Arab world will experience slower population growth. As a result of this global demographic movement, we can expect a massive shift to a multipolar world dominated by not one but many superpowers.
The rest of this future, as always, we will see later.
