October 31, 2011


The UN has pinpointed today, October 31st, 2011 as the day on which the world's population 'officially' reaches 7 billion people. The BBC has a fun application which commemorates this milestone in which you can work out what your personal number is. Apparently when I was born, I was the 5,073,149,636th person alive on Earth and the 80,017,084,400th person to have lived since history began. Crazy huh? It's difficult for anyone to conceptualise these numbers!

As the video goes on to explain though, the thing we should be trying to conceptualise is not literally the amount of space we are taking up as humans but rather, what kind of world is the seven billionth baby being born into?
