Recently I read a business magazine article reporting that China is importing 1 million tons of iron ore from Australia per day. I tried to wrap my head around the meaning of a million tons (2 billion pounds) of iron ore. Well, that is a little less than 5 ounces per day for each person on earth. In a year, this is about 114 pounds for each person on earth. Hmm. The yearly weight of iron ore being moved from Australia to China is perhaps 2/3 weight of the entire world’s population. I try to imagine 4.4 billion people a year moving to China.
All of this deep thinking reminded me of the “Sixteen Tons” song. Quoting from http://en.wikipedia.org/wiki/Sixteen_Tons:
