The arbitrary line for me is that I feel that every species that was here
when we arrived should be allowed enough habitat to continue to exist as a
species.  In other words, I draw the line at extinction.

This makes the problem of decision making simpler, since if you preserve
enough "safe" habitat for the most threatened, the less threatened will be
given a home.  That means that we need only focus upon a relatively few
indicator species in danger of being driven to extinction.  Robins and gray
squirrels are not among them.
