Sigh! How unfortunate that the wont of the human condition is to measure prosperity in terms economic growth, which is achieved by an increasing human population consuming more and more natural resources ... and polluting what's left. It doesn't take rocket science to realize that the bubble will burst sooner or later; we will either all perish from famine and pestilence or from wars fighting over increasingly fewer resources. I'd say there are maybe two or three human generations left on Earth, which further goes to make me wonder why humans are still popping kids. But, then, we aren't very good at seeing further than next quarter's profits ... or learning from our historical mistakes.
