The increase in health and life expectancy was historically unevenly spread throughout the world.īut over the last 200 years, Long Life and Good Health have generally increased throughout most of the world, and this has contributed to our exponentially huge population increase. In 1960 the average age of death was 53 years old, but now it is around 75 years old. The death rate has reduced, and people now live a lot longer and many more children are produced and live longer. Here is an excellent two and a half minute video which shows the history of the world’s population increase: On a graph, the increase looks like this: The following video shows how Bacteria divide and multiply exponentially.īy the year 2000, there were around 10 times more people on Earth than there were just 300 years ago in 1700. In addition to the explosion of humans on our own planet, Animals and Bacteria also increase exponentially. The world’s accelerating population growth is a major concern in terms of how our planet can feed and provide fuel for the current 7.2 billion plus people who currently live in our world. In this lesson we look at Exponential Growth of Populations.Įxponential growth involves increases starting off as reasonably small, and then dramatically increasing at a faster and faster rate.
