Getting crowded

In a rather underpublicized lecture last week Gen. Michael Hayden (CIA Director) said that one of the most important trends of the new Century is the population boom in poor countries. I recently heard George Gallup predict that we will hit 9 million in the next few decades. The problem is that we aren't acting like it. We are worrying about how to feed a few hundred thousand in some corner of the world instead of another 2 billion. What will that mean for planning? Will a few extra lots in South Brunswick suddenly pale in comparison?
