Reaching Seven Billion: The History of Population Control

Monday, October 24, 2011

The world's population is expected to reach seven billion on Monday, October 31, 2011. All this week The Takeaway looks at population growth and what it means for natural resources and the planet. High population growth has long concerned politicians and policymakers. The Earth's population first reached 1 billion in 1805, around the midpoint of the industrial revolution. From 1805 it took 123 years for the world's population to reach 2 billion. By contrast, it is estimated that it will only take 15 years until there are 8 million humans living on Earth.
