OK, now we're making some progress.
Quoted message said:What Is [censored] Sapiens' Place in Nature,
From an Objective (Biocentric) Point of View?
Michael J. Vandeman, Ph.D.

Quoted message said:"For hundreds of millenia, evolving humanity was a native species ... in
Africa and Asia. ... The modern Races of [censored] sapiens were a true alien
species when they colonized the rest of the world, from Australia to
the New World and finally the distant oceanic islands." E.O. Wilson,
p.98.
Quoted message said:"The behaviours animals use to avoid predators are both genetically
based and learned. The genetic component is acquired through natural
selection and so can only slowly be developed. This may account in
part for the fact that most of the world's surviving large mammals
live in Africa, for it was there that humanity evolved, and it was
only there that animals had the time to acquire the genetically based
behaviours that allowed them to cope with the new predator." Tim
Flannery, p.198.
These are valid points, but apply not only to man but to any species
that expands his range.
Quoted message said:"... his dominance and his faculties for upsetting so much of the rest
of life serve to rule him out of what we think of as 'natural'
relationships of living things". Paul Errington, p.41.
That's merely Errington's opinion based on his observations. I don't
agree with him. Man's
superior reasoning abilities give him an advantage over other animals,
but do not take him out
of the natural equation.
Quoted message said:Many answers have been given to this question, but none, to my
knowledge, based on science. Even scientists, apparently, often avoid
applying their knowledge when it may be inconvenient (e.g., interfere
with our preferred lifestyle). For example, open any biology textbook
and find where it defines "exotic species". Do you see any mention of
the fact that humans are, throughout most of our range, an exotic
species -- or even a discussion of whether we are an exotic species?
If biology is so valuable (which I think it is), why do we shy away
from using it?
Don't get the terms "exotic" and "invasive" confused. A predator that
naturally expands his range into an area where he did not previously
exist may be invasive, but he is not exotic. Early man expanded his
range into North America, for example, in search of better food and
shelter - natural drives.
For a species to be considered exotic requires the intervention of
man, either intentionally or unintentionally. I know that you don't
accept that definition, but scientists do.
Quoted message said:Another example: it is often claimed that humans are a natural
part of our environment -- we are just an animal like any other
animal. If that is true, then why aren't humans mentioned in the vast
majority of natural histories? The fact is, we consider ourselves a
part of our ecosystems when it's convenient (e.g. when we want to
justify recreation in wildlife habitat), and not, when it's not
convenient (e.g. when choosing where to live: in a house!). When you
die, will you re-enter the ecosystem just like any other dead
organism? No! We are either cremated, or buried in a box, specifically
to avoid the natural process of decay.
I rather prefer the Tibetan sky burial where the bodies of the dead
are offered to the vultures. Read about it at
http://www.ciolek.com/WWWVLPages/TibPages/tib-burial.html It seems
to be in closest harmony with nature.

This all boils down to whether one is a conservationist or a
preservationist. I am a conservationist. You are a preservationist.
Here's a pretty good explanation of the difference:
"Conservation & Preservation
"Those who are concerned with protecting the environment often use the
words conservation and preservation. These two terms are often
confused and are used to mean the same thing, although differences
exist.
Conservation is the sustainable use and management of natural
resources including wildlife, water, air, and earth deposits. Natural
resources may be renewable or non-renewable. The conservation of
renewable resources like trees involves ensuring that they are not
consumed faster than they can be replaced. The conservation of non-
renewable resources like fossil fuels involves ensuring that
sufficient quantities are maintained for future generations to
utilise. Conservation of natural resources usually focuses on the
needs and interests of human beings, for example the biological,
economic, cultural and recreational values such resources have. The
rain forest for example, contains a wide range of biodiversity,
providing food stocks for local populations and a source of timber and
medicines for other countries. Conservationists accept that
development is necessary for a better future, but only when the
changes take place in ways that are not wasteful. What the
conservationist opposes is not the harnessing of nature for mankind's
progression, but the fact that all too often the environment comes off
the worse for wear.
"Preservation, in contrast to conservation, attempts to maintain in
their present condition areas of the Earth that are so far untouched
by humans. This is due to the concern that mankind is encroaching onto
the environment at such a rate that many untamed landscapes are being
given over to farming, industry, housing, tourism and other human
developments, and that we our losing too much of what is 'natural'.
Like conservationists, some preservationists support the protection of
nature for purely human-centred reasons. Stronger advocates of
preservation however, adopt a less human-centred approach to
environmental protection, placing a value on nature that does not
relate to the needs and interests of human beings. Deep green ecology
argues that ecosystems and individual species should be preserved
whatever the cost, regardless of their usefulness to humans, and even
if their continued existence would prove harmful to us. This follows
from the belief that every living thing has a right to exist and
should be preserved."
