In order to understand the rate of population growth, you have to analyze the numbers. More than 300,000 years ago, the first homo sapiens lived in Africa. Fast forward 300,000 years to 1968 and there are 3.6 billion people already living on Earth.
In May 2020, the population topped 7.8 billion, more than twice the number just 50 years earlier. This means that we needed only 6,000th of the time to double the global population. At this rate, experts estimate that by the year 2100, more than 10 billion people will roam the Earth.
