Just 12 years after reaching 6 billion people, the population hit its next milestone of 7 billion on Monday Oct. 31.
The increase in population has sparked thoughts on the challenges associated with this increase according to this CNN article and how big that number really is.
“The number is just outside of our usual everyday scale of thinking,” Associate Professor Villanova University, Klaus Volpert was quoted saying in the article.
“We count to 10 on our fingers and that’s our scale, you know? Even counting to a million is already kind of outside of the everyday experience. And then once you go past a million, it becomes a blur,” he said.
To put the number in perspective, to take 7 billion steps at two feet per step, you could walk around the world 106 times, according to the article.
The U.N. has estimated a population of 9.3 billion by 2050 and more than 10 billion by 2100, according to the article.
