The destruction of the environment can bring long term
harm to all species.
A utilitarian argument will balance that harm against any short
term gain found in exploiting or using nature and its resources.
Bentham
A quantitative utilitarian
Would weigh up the amount of pleasure and pain
humans from present and future generation
would gain
Pleasure was to be preferred to
pain because that is how it is in
nature.
Believed in the important of sentient animals
beings considered wen discussing
environmental issues.
'the question is not, Can they reason? nor,
Can they talk? but, Can they suffer?'
Mill
A qualitative utilitarian
Would see the enjoyment of nature and a higher
pleasure and so may want to preserve the
environment.
Believed animals should be treated with
dignity but this is because a denial of this
would produce harmful effects on humans.
E.g. dog fighting is morally wrong since by causing
unnecessary suffering to animals those involved
degrade themselves
Singer
A preference utilitarian
Aims to maximise the pleasure of
all sentient beings.
Animals are capable of experiencing pain and
pleasure and their desire should be
considered. Speciesism is as wrong as racism
or sexism.
Singer however disregards the preferences of future
generations, his focus is on maximising preference
satisfaction for the current population.
Believed Christianity was bad for ecology
because of the belief that humans are more
important than animals.
Criticisms
Allows for people to exploit nature for
short-term human benefit.
Difficult to make a utilitarian calculation of
the consequences as we cannot know with
certainty what long term effects or
consequences of an action will be.
What may seem advantageous for the
environment may in the longer term
prove harmful.
Should future generations be included in the
consideration?
Case study
Bakun hydroelectric dam in Sarawak.
Destoryed rainforests, farmland and displaced indigenous people.
On the upside it is estimated that the dam could supply 20 million
homes with electricity.
