A gold star for Bill D!

The history of life on earth is full of examples of species becoming wildly sucessful, exploding across a habitat, exploiting every resource until they deplete or poison their habitat, or until they themselves create a ripe habitat for another species (e.g. another predator, or more likely a microbe).

Although we are the first species to be aware of this history, we certainly can't seem to overcome our overwhelming self-interest long enought to learn from it. The human population crash IS coming. Only questions are how soon, how sudden, how complete. My answers: in my daughters' lifetimes (aaaahhhh!), very sudden via pandemic or (less likely) nuclear holocaust, and not complete (the cycle will repeat...please read "A Canticle for Leibowitz").

What a lovely train of thought to start the day...
But everyone should be thinking it.
