If you’re interested in population ecology or population dynamics or just sustainability, then you might find this interesting…
_ Population size of the Earth now vs population size over history
If you add up the total number of humans who have ever lived and compare that total to the number of people walking around on the planet today, you’ll find that there are more people alive now than the sum total of all humans who have ever lived in the entire history of humanity.
If you’re just a geek, you’re probably going to mention this at some stage anyways ;-)
Seriously though, this is not a nice or encouraging graph to look at (which are these days?), and totally makes you wonder how the hell we’re going to support such a large human population in years to come…. ;-(
Thanks to Jeff for pointing me to this.
