Every human being on the planet should watch this, unfortunately many will never even have the opportunity to do so. When you have the time, please watch this video. It is 1 hr & 30 mins. I must say after watching it, I found myself sitting there thinking about what I had just learned, and how much of an impact it had on me. We have all heard something about the concerns with earths natural resources and climate change, but this really puts things in perspective.
