Would it be possible to even make a median, do you think? I mean, if you look at the median of a bunch of numbers, there is a logical progression from the beginning to the end; but there's no such progression if you take all of the people of the world and try to line them up next to each other.
I find all of the stories about the earth's population - 7 billion, by the end of 2010 - extremely fascinating, especially since I'm currently taking a course on world poverty and we've discussed many issues relating to population growth, and the effects on the environment, on cities, on development...
Incidentally, I also recently watched Last Train Home
, a documentary that explores the experience of a family of migrant workers. 130 million
of these migrant workers return home only once per year, for Chinese New Year - and just seeing the sheer amount of people in the train stations, traveling home to rural farms and rural towns, was really eye-opening.
(By the by, if you enjoy watching documentaries, Last Train Home
happens to be available on Netflix
There's an interesting article in the 7 Billion
series about humanity ushering in a new epoch called the "Age of Man"
, or officially termed the Anthropocene. It was a term created by a stratigapher (a type of geologist) and bandied about in the geologic community because of the suspected human impact on the world - on the atmosphere, on the environment, etc. - and whether or not that impact will be something of geologic significance. There's currently a debate on whether or not Anthropocene should be officially incorporated into the geologic time scale.
