This week's Please Explains is the second in our series on how to save the world—ways to approach complex global problems such as climate change, food supply, garbage disposal, the global water supply, and violence. Today we're looking at the population explosion—there are now 7 billion people on the planet. We're joined by Hania Zlotnik, director of the population Division at the Department of Economics and Social Affairs at the United Nations, and Dr.Joel E. Cohen, mathematical biologist and the head of the Laboratory of Populations at Rockefeller University and Columbia University, and author of How Many People Can the Earth Support?

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.
