Environmental Ethics: Week 1. Introduction
Environmental problems have been at the centre of modern public debate.
This course deals with the ethical issues raised by those environmental
problems and the different philosophical approaches that have been applied
to those issues.
As a way of beginning to think about those issues it is perhaps best
to begin with some particular examples.
1. Case studies
Exercise: Follow the links below to examine in more
detail one or more of the following examples:
Exxon-valdez
‘No
one anticipated any unusual problems as the Exxon Valdez left the Alyeska
Pipeline Terminal at 9:12 p.m., Alaska Standard Time, on March 23, 1989.
The 987foot ship, second newest in Exxon Shipping Company's 20-tanker
fleet, was loaded with 53,094,5 10 gallons (1,264,155 barrels) of North
Slope crude oil bound for Long Beach, California. Tankers carrying North
Slope crude oil had safely transited Prince William Sound more than 8,700
times in the 12 years since oil began flowing through the trans-Alaska
pipeline, with no major disasters and few serious incidents. This experience
gave little reason to suspect impending disaster. Yet less than three
hours later, the Exxon Valdez grounded at Bligh Reef, rupturing eight
of its 11 cargo tanks and spewing some 10.8 million gallons of crude oil
into Prince William Sound.
Until the Exxon Valdez piled onto Bligh Reef, the system designed to carry
2 million barrels of North Slope oil to West Coast and Gulf Coast markets
daily had worked perhaps too well. At least partly because of the success
of the Valdez tanker trade, a general complacency had come to permeate
the operation and oversight of the entire system. That complacency and
success were shattered when the Exxon Valdez ran hard aground shortly
after midnight on March 24.
No human lives were lost as a direct result of the disaster, though four
deaths were associated with the cleanup effort. Indirectly, however, the
human and natural losses were immense-to fisheries, subsistence livelihoods,
tourism, wildlife. The most important loss for many who will never visit
Prince William Sound was the aesthetic sense that something sacred in
the relatively unspoiled land and waters of Alaska had been defiled.
Industry's insistence on regulating the Valdez tanker trade its own way,
and government's incremental accession to industry pressure, had produced
a disastrous failure of the system. The people of Alaska's Southcentral
coast-not to mention Exxon and the Alyeska Pipeline Service Company-would
come to pay a heavy price. The American people, increasingly anxious over
environmental degradation and devoted to their image of Alaska's wilderness,
reacted with anger. A spill that ranked 34th on a list of the world's
largest oil spills in the past 25 years came to be seen as the nation's
biggest environmental disaster since Three Mile Island.’

Climate change
‘Climate
change is with us…Climatologists reporting for the UN Intergovernmental
Panel on Climate Change (IPCC) say we are seeing global warming caused
by human activities.
People are causing the change by burning nature's vast stores of coal,
oil and natural gas. This releases billions of tonnes of carbon dioxide
(CO2) every year, although the changes may actually have started with
the dawn of agriculture, say some scientists.
The physics of the "greenhouse effect" has been a matter of
scientific fact for a century. CO2 is a greenhouse gas that traps the
Sun's radiation within the troposphere, the lower atmosphere. It has accumulated
along with other man-made greenhouse gases, such as methane and chlorofluorocarbons
(CFCs). Some studies suggest that cosmic rays may also be involved in
warming.
If current trends continue, we will raise atmospheric CO2 concentrations
to double pre-industrial levels during this century. That will probably
be enough to raise global temperatures by around 2°C to 5°C. Some
warming is certain, but the degree will be determined by cycles involving
melting ice, the oceans, water vapour, clouds and changes to vegetation.
Warming is bringing other unpredictable changes. Melting glaciers and
precipitation are causing some rivers to overflow, while evaporation is
emptying others. Diseases are spreading. Some crops grow faster while
others see yields slashed by disease and drought. Clashes over dwindling
water resources may cause conflicts in many regions.
As natural ecosystems - such as coral reefs - are disrupted, biodiversity
is reduced. Most species cannot migrate fast enough to keep up, though
others are already evolving in response to warming.
Thermal expansion of the oceans, combined with melting ice on land, is
also raising sea levels. In this century, human activity could trigger
an irreversible melting of the Greenland ice sheet. This would condemn
the world to a rise in sea level of six metres - enough to flood land
occupied by billions of people.’

On the one hand:
'We have to recognise that tigers cannot coexist with high density
human settlements living off market-driven economic activities like
agriculture and forest biomass exploitation. Therefore, human and livestock
population densities need to be reduced inside prime tiger habitats
through sensible and fair relocation policies, to allow wild ungulate
prey to recover from habitat pressures, poaching and competition with
livestock'.

On the other:
‘[E]every attempt by the people of Nagarahole to defend their
rights has come under attack. The people have not alternative but to
resort to peaceful non-cooperation and protest. They however believe
that they have the right and knowledge to manage their traditional territories
in the best interests of conservation of biodiversity and wild life…
The Nagarahole forests must be under the direct supervision of the adivasi,
in tune with their indigenous identity and with due recognition and
powers to their conservation idioms with the guarantee that there would
be no forced re location of any of these adivasi families from their
habitat.’

The ruddy duck problem:
'The UK's Ruddy Duck
Problem'
As
numbers of ruddy ducks have increased in the UK, so have the numbers
of birds recorded in continental Europe. There have been over 900 records
of some 1,500 ruddy ducks in 21 European and North African countries.
Ruddy ducks were first seen in Spain in 1983 and records have since
become more frequent, with about 20 birds occurring annually. The two
species have begun to interbreed, producing fertile hybrid offspring.
International conservation organisations and European governments believe
that hybridisation with ruddy ducks poses a very serious threat to the
survival of the globally threatened white-headed duck. Ruddy ducks are
naturally more promiscuous in their mating behaviour than white-headed
ducks. If the number of ruddy ducks reaching Europe from the UK is allowed
to continue to increase, there is a danger that the more competitive
ruddy duck will inundate the Spanish white-headed duck population. The
likely result would be a population of hybrid birds with individual
birds showing, over time, fewer and fewer characteristics of white-headed
ducks. The population would eventually comprise solely ruddy ducks…Not
only are ruddy ducks reaching Spain, they have recently been recorded
in Turkey - the wintering grounds of the main central Asian population
of white-headed ducks. If ruddy ducks become established here and spread
eastwards, control would be impossible due to a lack of infrastructure
and resources. Therefore, there is an urgent choice to make: act now
to combat this threat, or allow ruddy ducks to continue to increase
and spread across Europe, placing the world population of white-headed
ducks in jeopardy. The evidence strongly suggests that UK birds are
responsible for the ruddy duck's spread across Europe. Without control
of this core population in the very near future, conservation measures
on the continent are unlikely to succeed. RSPB

Animal Aid will be at the Wildfowl and Wetlands Trust (WWT), Slimbridge
on Good Friday (April 2nd) to protest against the organisation's support
for the government's planned slaughter of thousands of ruddy ducks…The
WWT protest concludes a Week of Action directed at the major cull supporters.
Demonstrations have also taken place at the Royal Society for the Protection
of Birds, the Countryside Council for Wales and English Nature. The
protests are the opening salvos in a sustained campaign designed to
force a cancellation of the planned killing…The supposed 'logic'
behind the killing is that ruddys, introduced to Britain from North
America by the WWT itself, have bred and spread to Spain where they
are mating with the endangered white-headed duck (endangered because
it has been hunted and its habitat destroyed by people). The result
of this mating is an 'impure' hybrid. Those promoting the cull are deeply
offended by this mixing of blood, even though the ruddys and the white
headed ducks can produce healthy offspring and are therefore close genetic
kin. Animal

Poverty and pollution:
Everyone should have the right to live in a clean, safe environment.
There is no place in a modern society for factories spewing out thousands
of tonnes of carcinogenic chemicals. This alone should be cause for
strong action to reduce pollution from factories. But the fact that
this pollution is also in the most deprived areas of the country makes
action even more vital. It is morally wrong that on top of all the other
problems that poorer communities face, they should have to bear the
burden of factory pollution as well… 'Pollution
and Poverty - Breaking the Link'
Consider one or more of the cases above in detail and
answer the following questions:
- a) What environmental goods and bads are in dispute?
Why does the environment matter in these cases?
- b) To whom does the environment matter?
- c) What conflicting human interests are involved?
- d) What impact does the problem have on individual
animals; on other individual organisms; on species as a whole; on ecosystems?
- e) Do you think these impacts are bad or good? What
would constitute "bad" and "good" in each case?

and A. Light Values and the Environment.
2. Why do environments matter?
There are a variety of different ways in which our environments and the
other beings who share those environments matter to us.
- we live from them - they are the means to our existence.
- we live in them - they are our homes and familiar places in which
everyday life takes place and draws its meaning, and in which personal
and social histories are embodied.
- we live with them - our lives take place against the backdrop of a
natural world that existed before us and will continue to exist beyond
the life of the last human.
1. Living from the world
We live from the world: we mine its resources; cultivate and harvest its
fruits; shape the contours of the land for human habitation, roads, minerals
and agriculture; dredge rivers for transport. And all these activities
are subject to the action of the natural world: flood, drought, hurricane,
earthquake and landslide can be a source of ruined endeavour and human
sorrow. Human life, health and economic productivity is dependent upon
the natural and cultivated ecological systems in which we live - on their
capacity to assimilate the wastes of economic activity and to provide
its raw materials. The damage that economic activity does to these capacities,
accordingly, is a major source of increased environmental concern.
2. Living in the world
We live in the world. The environment is not just a physical precondition
for human life and productive activity, it is where humans (and other
species) lead their lives. Environments matter to us for social, aesthetic
and cultural reasons. Some of this dimension often comes under the heading
of 'recreation value' in economic texts, and for some part of the role
that the environment plays in human life the term is a quite proper one:
it catches the way in which forests, beaches, mountains, and rivers are
places in which social and individual recreation - of walking, fishing,
climbing, swimming, of family picnics and play – take place. However
the term 'recreation' can be misleading in the sense that it suggests
a view of the natural environment as merely a playground or spectacle,
which might have substitutes in a local gym, or art gallery, whereas the
places in question might have a different and more central part in the
social identities of individuals and communities. Particular places matter
to both individuals and communities in virtue of embodying their history
and cultural identities. The loss of aesthetically and culturally significant
landscapes or the despoliation of particular areas matters in virtue of
this fact.
3. Living with the world
We live with the world: the physical and natural worlds have histories
that stretch out before humans emerged and have futures that will continue
beyond the disappearance of the human species. This fact is one to which
environmentalists often make appeal. Correspondingly a source of growth
in environmental concern has been the life sciences and nature conservation
movement. The loss of biodiversity, the disappearance of particular habitats
and the extinction, local and global, of particular species of flora and
fauna have all become increasingly central to public debate and policy
making. A good part of people’s concern is not about the conservation
of natural resources or about cultural significance, as such, but about
the natural world as a direct object of value, often quite independent
of any use it might have for individuals. This concern has been voiced
by philosophers in terms of the 'intrinsic value' of nature and by economists
in terms of its 'existence value'. Whether either term has done much to
clarify the issues is a moot point to which we return later.
Exercise:
Consider how these three different dimensions
figure in the cases outlined above.
3. Value conflicts
Conflicts can exist between different kinds of value that might be attributed
to the environment. For example, the drainage of marshland from the economic
perspective of agricultural productivity and the possibility of increasing
sustainable agricultural yields over time might count as improvement;
but from the perspective of biodiversity or the cultural significance
of ancient marshes it may be damaging. Conversely, a farmer might see
the decision to flood as damaging and will worry about the growing influence
of conservation policy on the future of his livelihood.
Exercise:
Consider the cases with which we started. What are the
conflicts involved?
How do you think they might be properly resolved?
4. The distribution of goods and harms.
Environmental choices have a clear distributional dimension. They take
place in the context of inequalities in property and power; they have
consequences for the subsequent distribution of damages and goods across
different groups, often falling hardest on the poorest. Public decisions
and actions distribute environmental goods and harms among different persons
and beings. They raise problems of the equity or justice of the actions.
Exercise:
Consider
the cases above. How are different goods and harms distributed among the
affected parties?
Who is damaged and who gains the benefits?
How should we decide if a given distribution is justified
or not?
5. Addressing conflicts
Environments are sites of conflict between different values and different
social groups. They are also sites of conflict within social groups and
even within individuals, where they appear as dilemmas. These conflicts
occur at a number of different levels - at the local level in the management
of environmentally significant sites, at the level of decisions about
specific economic and environmental projects, at the level of policy and
at the level of regulation. They are conflicts that concern both citizen
and policy maker.
Exercise:
Consider the conflicting interests and values in the
cases with which we started. How should such conflicts to be resolved?
6. Utilitarianism
One response to the problem of value conflict is to find a common measure
of values through which the gains and losses in different values can be
traded off one with another. The most well-known version of this position
is utilitarianism which still dominates a great deal of public policy
making.
The utilitarian tradition approaches the issue of apparent conflicts
between different values and interests by attempting to find some measure
through which different ends can be traded off with each other so as to
maximise the total welfare of affected agents.. Hence we need a measure
of welfare such that gains and losses in welfare can be appraised and
the choice that produces the greatest total welfare be discerned. Thus
utilitarianism, understood as an account of decision making, recommends
the policy that maximises the welfare of affected agents.
Classical Utilitarianism: The right action is that which has the consequences
which maximises the well-being or happiness of affected agents i.e. the
best action is that which produces the greatest improvement in well-being
of affected agents.
Exercise:
What
implications do you think the utilitarian approach would have for the
cases you have examined above?
What problems did you have in applying the case?
Do you think the utilitarian approach to that case looks
plausible?
Next week we will consider this utilitarian approach in more detail.
