“Psychologically it is an important step for mankind,” Hania Zlotnik, director of the United Nations Population Division, told the BBC. 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. “It’s an increasing trend that is becoming more obvious. People do not realise how rural the world was until recently. That is changing,” Zlotnik said. BBC
