If ecology is the study of organisms and their evolution and interactions
with their environment, living and non-living (or in other similar words),
one of the most fundamental observations that can be made in that regard is
that only one species is so organized as to INTENTIONALLY go beyond its
needs in its interactions.
Most organisms' populations fluctuate, in smaller or greater part, in some
kind of relation to the feedback loop of consequences that result from the
direct and indirect effects of its actions upon its environment, and, in
smaller or greater part, are affected by the consequences of the actions, in
the aggregate and in the particular, of other species.
Each species has limited control of some of the variables affecting itself,
but even that control is an action that will, sooner or later, feed back
(blowback?) to each species and other species.
I respectfully offer these points for review, criticism, and revision.
