The world is a city

Let's look at the bright side. 1. The human race will not disappear in the near future. According to a new UN report, the world’s population will reach 6.5 billion this year, and could reach 7 billion in 2012 and stabilize at 9 billion in 2050. 2. Because of the global urbanization trend we will never feel living alone again. 50% of the world's population will live in cities in 2 years. That's up from 30% in 1950. U.N. Commission on Population and Development estimates that number will be 61% of the global population by 2030. 20 cities now have 10 million or more inhabitants, compared with just 4 - Tokyo, New York, Shanghai and Mexico City - in 1975 and just 4 - New York and Tokyo - in 1950.
