Please don't just paste AI-generated summaries into a low-effort comment. I don't know why your summary only picked up on the first half of the first paragraph, but estimating global population volume has nothing to do with the article. Also, even taking the assumptions at face value, your model's calculations are wrong by several orders of magnitude. There are not 5,280 square feet in one square mile and 600*5280 is not 3,160,000,000.
