New statistics and studies done by the United Nations (UN) Population Division has estimated that by 2100, the population will hit 11 billion, which might significantly affect the quality of life on our planet. Overpopulation is already an issue taken into study by many and has been said to be the main cause of numerous problems.
However, our current 7.3 billion might just be nothing in comparison to what is to come by the turn of the century. In only 35 years, the population is set to reach 9.7 billion and then to climb over the 11.2 billion mark by 2100, which will unfortunately aggravate already existing problems across the globe.
Pollution and food scarcity might be two very serious issues which we now have to somehow combat and accommodate to before the future brings an even more damaging consequence to humanity.
According to John Wilmoth, director of the UN Population Division, damaging factors such as lack of resources, unemployment, poverty, crime and political unrest should be taken into consideration.
It seems that Asia will maintain its title of ‘most populated continent’, by going from the current 4.4 billion people to 5.3 billion in 2050 and then to steadily lower back to 4.9 billion. Still, it will be a considerable increase to an already overpopulated continent that is streaked with issues, such as poverty and disease due to poor conditions and crowded communities.
Among all, however, it seems that Africa will see the most significant increase. Currently standing at 1.2 billion, the African continent might see a rise in population that could range between 3.4 billion and 5.6 billion by 2100 due to the rising to high levels of fertility and the near stop in the rate of fertility decline.
In fact, Africa’s most populous country, Nigeria, will go from a population of 182 million to a whopping 752 million by 2100, which is the biggest increase any region will see in the next eighty five years. It’s estimated that even if the fertility rate take a steep fall, the African country will still see its population doubled at the very least.
The United States is set to expand as well, though in a very small increment when compared against others, with a rise from the current 322 million people to 450 million by 2100. However, it has also been observed that the average age will go from 38 years old to 44.7 years old, which means that the U.S. population is steadily aging. The support ratio will fall, which implies that a need for better pension plans should be considered early on.
Measures might have to be taken across the entire world to prevent overpopulation to an alarming degree, because there’s only so much our planet can take.
