Suzuki on exponential growth

On November 28, Tony created a post that has proven to be one of our most popular ever.  It was a blast at the techno-pessimists and spoke of hopeful possibilities.  It was called Would'ya like a serving of hope for Thanksgiving?

Even though I am not willing to go so far as to claim that shortages are the result of bad economics, his post was quite persuasive.  I want to make this blog more upbeat.  But I also want to keep things mathematically literate.

I already have a highlight post that covers this subject—Elevator Speech #2--Continuous geometric growth in a finite biosphere is impossible.  Look for it on the left side.  But I also found this little gem starring David Suzuki that describes the problem of geometric growth about as well as it can be done.

In short, I want to get more optimistic but I intend to remain firmly grounded.
