gorillas over those of grasses. If, however, the point is that
|
humans, gorillas, yeasts, and grasses are all parts of an interrelated
|
whole, then it can still be asked how this establishes that
|
they are equal in intrinsic worth. Is it because every living thing
|
plays its role in an ecosystem on which all depend for their
|
survival? But, firstly, even if this showed that there is intrinsic
|
worth in micro-organisms and plants as a whole, it says nothing
|
at all about the value of individual micro-organisms or plants,
|
since no individual is necessary for the survival of the ecosystem
|
as a whole. Secondly, the fact that all organisms are part of an
|
interrelated whole does not suggest that they are all of intrinsic
|
worth, let alone of equal intrinsic worth. They may be of worth
|
only because they are needed for the existence of the whole,
|
and the whole may be of worth only because it supports the
|
existence of conscious beings.
|
The ethics of deep ecology thus fail to yield persuasive answers
|
to questions about the value of the lives of individual living
|
beings. Perhaps, though, this is the wrong kind of question to
|
ask. As the science of ecology looks at systems rather than
|
individual organisms, so ecological ethics might be more plausible
|
if applied at a higher level, perhaps at the level of species
|
and ecosystems. Behind many attempts to derive values from
|
ecological ethics at this level lies some form of holism - some
|
sense that the species or ecosystem is not just a collection of
|
individuals, but really an entity in its own right. This holism is
|
made explicit in Lawrence Johnson's A Morally Deep World.
|
Johnson is quite prepared to talk about the interests of a species,
|
in a sense that is distinct from the sum of the interests of each
|
member of the species, and to argue that the interests of a
|
species, or an ecosystem, ought to be taken into account, alongside
|
individual interests, in our moral deliberations. In The Ecological
|
Self, Freya Mathews contends that any 'self-realising
|
system' has intrinsic value in that it seeks to maintain or preserve
|
282
|
The Environment
|
itself. While living organisms are paradigm examples of selfrealising
|
systems, Mathews, like Johnson, includes species and
|
ecosystems as holistic entities or selves with their own form of
|
realisation. She even includes the entire global ecosystem, following
|
James Lovelock in referring to it by the name of the
|
Greek goddess of the earth, Gaia. On this basis she defends her
|
own form of biocentric egalitarianism.
|
There is, of course, a real philosophical question about
|
whether a species or an ecosystem can be considered as the sort
|
of individual that can have interests, or a 'self' to be realised;
|
and even if it can, the deep ecology ethic will face problems
|
similar to those we identified in considering the idea of reverence
|
for life. For it is necessary, not merely that trees, species,
|
and ecosystems can properly be said to have interests, but that
|
they have morally significant interests. If they are to be regarded
|
as 'selves' it will need to be shown that the survival or realisation
|
of that kind of self has moral value, independently of the value
|
it has because of its importance in sustaining conscious life.
|
We saw in discussing the ethic of reverence for life that one
|
way of establishing that an interest is morally significant is to
|
ask what it is like for the entity affected to have that interest
|
unsatisfied. The same question can be asked about selfrealisation:
|
what is it like for the self to remain unrealised? Such
|
questions yield intelligible answers when asked of sentient
|
beings, but not when asked of trees, species, or ecosystems. The
|
fact that, as James Lovelock points out in Gaia: A New Look at
|
Life on Earth, the biosphere can respond to events in ways that
|
resemble a self-maintaining system, does not in itself show that
|
the biosphere consciously desires to maintain itself. Calling the
|
global ecosystem by the name of a Greek goddess seems a nice
|
idea, but it may not be the best way of helping us to think
|
clearly about its nature. Similarly, on a smaller scale, there is
|
nothing that corresponds to what it feels like to be an ecosystem
|
flooded by a dam, because there is no such feeling. In this respect
|
trees, ecosystems, and species are more like rocks than they are
|

Practical Ethics
|
like sentient beings; so the divide between sentient and nonsentient
|
creatures is to that extent a firmer basis for a morally
|
important boundary than the divide between living and nonliving
|
things, or between holistic entities and any other entities
|
that we might not regard as holistic. (Whatever these other
|
entities could be: even a single atom is, when seen from the
|
appropriate level, a complex system that 'seeks' to maintain
|
itself.)
|
This rejection of the ethical basis for a deep ecology ethic does
|
not mean that the case for the preservation of wilderness is not
|
strong. All it means is that one kind of argument - the argument
|
from the intrinsic value of the plants, species, or ecosystems -
|
is, at best, problematic. Unless it can be placed on a different,
|
and firmer footing, we should confine ourselves to arguments
|
based on the interests of sentient creatures, present and future,
|
human and non-human. These arguments are quite sufficient
|
to show that, at least in a society where no one needs to destroy
|
wilderness in order to obtain food for survival or materials for
|
shelter from the elements, the value of preserving the remaining
|
significant areas of wilderness greatly exceeds the economic
|
values gained by its destruction.

DEVELOPING AN ENVIRONMENTAL ETHIC
|
In the long run, the set of ethical virtues praised and the set of
|
ethical prohibitions adopted by the ethic of specific societies will
|
always reflect the conditions under which they must live and
|
work in order to survive. That statement is close to being a
|
tautology, because if a society's ethic did not take into account
|
whatever was needed for survival, the society would cease to
