Today we turned 7 billion people on the earth. When I grew up in the 1980s, I remember we talked about turning 5 billion people. A magical number that made us learn about the world population in several weeks in school; discussing and drawing more or less successful children sketches of our multi-faceted and common world. My father has seen the world population triple fold in his life time; In 1940 there were 2,3 billion world citizens according to UN. UN estimates that the growth rate will now decline some, but still we will probably turn 9 billion people in 2050. What does these figures imply for manufacturing industries worldwide?
