The cities of the planet are growing in both numbers and influence. United Nations predicts that in 2050 about 66% of the human population on this planet will not live in rural but in urban areas. Comparing this to 30% in 1950 the global rate by which the cities are growing is amazing. In Sweden, where I live, the urbanized part of the population today is 86% and is predicted to rise to 90% in 2050 i e 9 out of 10 people are soon living in cities in Sweden. For a country which was late into the industrialization and urbanization game this shift is quite extraordinary even if it currently being dwarfed by many fast urbanizing countries outside the West.
