The world in numbers

You wanna see something creepy? Guy came to my job to help out with some repairs (damn broken heater), and we got to talking about the number of people who use the internet in a given day.

It's hard to say what I'm more freaked out by, the global population, the growing debt, the carbon dioxide output, or the number of people who spend their time in front of some sort of electronic device (TV, computer, cell phone, etc.) vs. the number of new books published.

What did you find most interesting/creepy?
