Earlier today I shared three ways to look at the world as a village. Those infographics try to help us see the world in numbers that we can relate to. On the opposite end of the spectrum we have to consider the challenges posed by a global population that now exceeds seven billion people. The National Geographic video embedded below gives a quick overview of how the population grew to
nearly 7 billion and the challenges presented by a population of 7
billion.

Applications for Education
Before showing the video to your students you might want to share a couple of other National Geographic videos that attempt to help us understand how big seven billion really is. One of those National Geographic videos is about the space needed to host a party for seven billion people. How Big Is 7 Billion? video attempts to put seven billion into terms we can relate to. After watching all of these short videos ask your students to develop and
propose their own responses to the challenges presented by a growing
population.
