6.6 billion people!

UNFPA was announced that the world's population had exceeded 6.6 billion. Three high rank countries are China, India, and the United States . The population of Japan is 128.3million people, and continuous the tenth places for three years. It is said that more than 3.3 billion people come to live in the city part in 2008, and the number becomes about five billion people in 2030. This is the very big number! More expansion of the area development is predicted as this result, but it has the possibility to bring the aggravation of the poverty and the aggravation of the environment, too. Anyway, the environment that surrounds us will change more greatly.
