exist. Many of the ethical standards that we accept today can |
be explained in these terms. Some are universal and can be |
expected to be beneficial to the community in virtually any |
conditions in which humans live. Obviously a society in which |
members of the community are permitted to kill each other with |

impunity would not last long. Conversely, the parental virtues |
of caring for children, and other virtues like honesty, or loyalty |
to the group, would foster a stable and lasting community. Other |
prohibitions may reflect specific conditions: the practice among |
the Eskimo of killing elderly parents no longer able to fend for |
themselves, is often cited as a necessary response to life in a |
very harsh climate. No doubt the slow pace of changing climatic |
conditions, or of migration to different regions, allowed time |
for systems of ethics to make the necessary adjustment. |
Now we face a new threat to our survival. The proliferation |
of human beings, coupled with the by-products of economic |
growth, is just as capable as the old threats of wiping out our |
society - and every other society as well. No ethic has yet developed |
to cope with this threat. Some ethical principles that |
we do have are exactly the opposite of what we need. The |
problem is that, as we have already seen, ethical principles |
change slowly and the time we have left to develop a new |
environmental ethic is short. Such an ethic would regard every |
action that is harmful to the environment as ethically dubious, |
and those that are unnecessarily harmful as plainly wrong. That |
is the serious point behind my remark in the first chapter that |
the moral issues raised by driving a car are more serious than |
those raised by sexnal behaviour. An environmental ethic would |
find virtue in saving and recycling resources, and vice in extravagance |
and unnecessary consumption. To take just one example: |
from the perspective of an environmental ethic, our |
choice of recreation is not ethically neutral. At present we see |
the choice between motor car racing or cycling, between water |
skiing or windsurfing, as merely a matter of taste. Yet there is |
an essential difference: motor car racing and water skiing require |
the consumption of fossil fuels and the discharge of carbon |
dioxide into the atmosphere. Cycling and windsurfing do not. |
Once we take the need to preserve our environment seriously, |
motor racing and water skiing will no more be an acceptable |
form of entertainment than bear-baiting is today. |

Practical Ethics |
The broad outlines of a truly environmental ethic are easy to |
discern. At its most fundamental level, such an ethic fosters |
consideration for the interests of all sentient creatures, including |
subsequent generations stretching into the far future. It is accompanied |
by an aesthetic of appreciation for wild places and |
unspoiled nature. At a more detailed level, applicable to the |
lives of dwellers in cities and towns, it discourages large families. |
(Here it forms a sharp contrast to some existing ethical beliefs |
that are relics of an age in which the earth was far more lightly |
populated; it also offers a counterweight to the implication of |
the 'total' version of utilitarianism discussed in Chapter 4.) An |
environmental ethic rejects the ideals of a materialist society in |
which success is gauged by the number of consumer goods one |
can accumulate. Instead it judges success in terms of the development |
of one's abilities and the achievement of real fulfilment |
and satisfaction. It promotes frugality, in so far as that is |
necessary for minimising pollution and ensuring that everything |
that can be re-used is re-used. Carelessly to throw out material |
that can be recycled is a form of vandalism or the theft of our |
common property in the resources of the world. Thus the various |
'green consumer' guides and books about things we can |
do to save our planet - recycling what we use and buying the |
most environmentally friendly products available - are part of |
the new ethic that is required. Even they may prove to be only |
an interim solution, a stepping-stone to an ethic in which the |
very idea of consuming unnecessary products is questioned. |
Wind-surfing may be better than water-skiing, but if we keep |
on buying new boards in order to be up to date with the latest |
trends in board and sail designs, the difference is only marginal. |
We must re-assess our notion of extravagance. In a world |
under pressure, this concept is not confined to chauffeured limousines |
and Dom Perignon champagne. Timber that has come |
from a rainforest is extravagant, because the long-term value |
of the rainforest is far greater than the uses to which the timber |
is put. Disposable paper products are extravagant, because an- |

cient hardwood forests are being converted into wood-chips |
and sold to paper manufacturers. 'Going for a drive in the country' |
is an extravagant use of fossil fuels that contributes to the |
greenhouse effect. During the Second World War, when petrol |
was scarce, posters asked: 'Is your journey really necessary?' |
The appeal to national solidarity against a visible and immediate |
danger was highly effective. The danger to our environment is |
less immediate and much harder to see, but the need to cut out |
unnecessary journeys and other forms of unnecessary consumption |
is just as great. |
As far as food is concerned, the great extravagance is not |
caviar or truffles, but beef, pork, and poultry. Some 38 per cent |
of the world's grain crop is now fed to animals, as well as large |
quantities of soybeans. There are three times as many domestic |
animals on this planet as there are human beings. The combined |
weight of the world's 1.28 billion cattle alone exceeds that of |
the human population. While we look darkly at the number of |
babies being born in poorer parts of the world, we ignore the |
over-population of farm animals, to which we ourselves contribute. |
