A semana em que o mundo mudou

"A major demographic shift took place on Wednesday, May 23, 2007: For the first time in human history, the earth's population is more urban than rural. According to scientists from North Carolina State University and the University of Georgia, on that day, a predicted global urban population of 3,303,992,253 exceeded that of 3,303,866,404 rural people. In the US, the tipping point from a majority rural to a majority urban population came early in the late 1910s."
