How Did We Get to 7 Billion from 1 Billion People in Just 200 Years? (Video)

Via NPR:

It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West. U.N. forecasts suggest the world population could hit a peak of 10.1 billion by 2100 before beginning to decline. But exact numbers are hard to come by — just small variations in fertility rates could mean a population of 15 billion by the end of the century.

      Isn’t he the guy that’s always wrong because never took science advance in his projections?

    My working hypothesis is that it was done with lots and lots of sex. But lets watch the video anyway and see what they say.

    • I’m going to need to have a few trial runs before I can confirm your hypothesis. I’ll need a sample size of a few thousand before I can come to any proper conclusions.

        Hear hear! I concur with my learned colleague. This must be investigated, stand back everyone were going to try science.
