Earth’s Human Population hits 8 billion mark

by Subhechcha Ganguly

Tuesday marked the arrival of the planet’s 8 billionth person, a momentous occasion for humanity that will likely cause India to surpass China as the world’s most populous nation next year amid escalating international problems.

On November 15, the population clock flashed 8,000,000,000, with the world’s population having increased by one billion during the previous 12 years.It took approximately 300,000 years after Homo sapiens first appeared for there to be one billion of us on the planet.

The UN estimates that it will take until 2080 to reach 10 billion people, which indicates that the global population’s overall growth rate is declining. It may take 15 years to reach nine billion people. Low and declining fertility rates are a major factor in population decline on a worldwide scale, the UN said.

Numerous climate and population experts told The Associated Press that while more people using energy, primarily from the burning of fossil fuels, is warming the planet, the real problem is how a small percentage of those people are contributing far more than their fair share of carbon pollution.

With historically high birth rates, Africa is also experiencing a drop. The continent experienced approximately 6.5 live births per woman between 1950 and 1980.Today, there are about 4.4 live births per woman. Although it may not appear to be a significant fall, not all regions of the continent are experiencing a decline in births at the same rate.However, China and India, two of the most populous nations, provide two of the most prominent instances.India and China both have slightly smaller populations than 1.4 billion, respectively. However, fertility rates have decreased in both nations.
