Hans Roslings 200 years in 4 minutes.

We watched a short clip in class of a man name Han Rosling. In the video he was explaining  what has happened to the population over 200 years. Han is a college professor and teaches Global Health. He uses simple tricks in order for us to understand what he is saying more. For example he color coded a few regions. Europe was brown, Asia was red, the Middle East was green, Africa (south of the Sahara) was blue, and The Americas were yellow. With these colors he created a graph. The y-axis on the graph represented lifespan and the x-axis represented income. Based on income and lifespan the colored dots would move up or down. If you are closer to zero then your area is poor and sick but if you have a high lifespan and income then you are rich and healthy. Hans made it easier for us to understand the information he was sharing by doing this.
