7 Billion

Description:

Scientists estimate that on Halloween 2011 the global population reached 7 billion. In this lesson we’ll explore how many people the Earth is adding and losing each minute, and use this to determine the [exponential] growth rate. We’ll also predict what the world population will be in the future, and what life will be like with more and more people.
