(Via BBC) Half of humanity set to go urban according to a prediction by the United Nations. There are concerns that, in developing countries, basic provisions in cities will lag behind population growth. Observers will see increased pressure placed on resources and services as humankind becomes an urban species. Despite almost four millennia as centres of civilisation, it was only fairly recently that cities attracted more than a small percentage of the global population. With hindsight, the 20th Century was the century of urbanisation. In 1900, only 14% of humanity lived in cities. By the century's close, 47% of us did so. This change is revealed in the growth of the number of medium-sized cities. In 1950, there were 83 cities with populations exceeding one million; but by 2000, this had risen to 411.
