Watch how fast the population of the world increases every second

The population of the earth is well on its way to 7 billion. Watch the geometric progression happen in real time on this site. Your computer should be able to run the Java applet that the site utilizes for the computation. Will we reach the point where there won’t be space enough for everyone on the planet? With food production increasing arithmetically, will there be mass starvation?
