Subject: Re: Limits, We don't have no stinkin' Limits
I have a science fiction image of the inverse relationship of the extinction of species with the growth of human populations.
What happens to all those sentient animals we have killed and continue to kill off? The great mystery, in an effort to maintain balance, rather than creating humans a la The Island of Doctor Moreau, "souls" migrate from the former to the latter.

Humans have become rather matter of fact about the whole process without really examining it.
