In 1804, the global population reached one billion. In 2011 the global population reached 7 billion.

Because of better medicine and living conditions, means there is a higher life expectancy for children, which is dramatically increasing the world population.

Fortunately, we are still nowhere near running out of space, although resources are a higher concern.

Let’s find out the science between how we got to this point by checking out the video below to explain it all!
