I remember an old college lecture, where our prof highlighted that the Earth can sustain 30 billion people.The problem is human management..That's 30 billion people spread out and not concentrated. 30 billion people spread out and on the same page would be fantastic really!..Think of the innovations and creations that would come out of such a large pool of humans. but sadly we would screw it up, like we have done and keep doing.
