I agree. Isn't it obvious that an "indefinite population growth" will collide with a "finite planet earth" (Or even a finite universe for our believers in technology :-)? Somebody posted a nice video on the exponential function in my "Ponzi" diary.
The problem is that the mainstream economic religion says that our economy needs growth. And population growth is "Growth for Dummies" to paraphrase popular book titles. This reminds me of my old diary Beyond Ponzi Economy
