Here you will find a listing of essential facts about the planet earth, the home to all of humanity:
Human Population of the Earth: 6,660,000,000 (6.66 billion) as of April 2008
World Population Growth: 1.14% - 2006 estimate (this means at the current rate of growth, the earth's population will double in 61.4 years)


Countries of the World: 195
Earth's Circumference at the Equator: 24,901.55 miles (40,075.16 km)
