Can we survive

This article raises a very cool question on if the world can sustain life past nine billion people. I find it funny that as the world continues to increase in population the number of people that are thought to be sustainable continues to rise. We find new ways to do something and new ways to make something better. Personally, I think a disease is going to sweep through the world and wipe out people to control the population, just like what happens in nature to control the population. If the world is able to sustain the population, then another question arises as to if the world is big enough to hold all of the extra people. My opinion is that the world will never make it that big but if it is able to get there, it will be interesting to see how we were able to do it.
