Conceptualizing a world with 7B+ people is HARD. I have no point of reference for what a BILLION people is, save China and India, and since I've never been in a room with all the Chinese or Indians in the world at once, it's still pretty rough for me.
Let's be real. I've never counted past 100 without getting a bit bored. But I can count to 100. So let's conceptualize the world today in 100. Sounds lovely.
Toby Ng makes this possible by creating a 20 poster series that parses up the resources, religion, literacy, birth, death, etc in a bunch of different ways. Best of all, you can purchase the postcard series for just under $25. Cool for a bellringer exercise at the beginning of class.
GREAT for when you start talking CompPol.
