Animal experimentation

A difficult event

In 1997 Dr Jay Vacanti and his team grew an ear on the back of a mouse

Brute experiments are widely used to develop new medicines and to examination the rubber of other products.

Many of these experiments cause hurting to the animals involved or reduce their quality of life in other means.

If information technology is morally incorrect to crusade animals to suffer then experimenting on animals produces serious moral problems.

Animal experimenters are very aware of this ethical problem and acknowledge that experiments should be made as humane equally possible.

They also agree that it's incorrect to utilise animals if alternative testing methods would produce equally valid results.

Two positions on beast experiments

• In favour of creature experiments:
• Experimenting on animals is acceptable if (and only if):
  • suffering is minimised in all experiments
  • human benefits are gained which could not be obtained past using other methods
• Against fauna experiments:
• Experimenting on animals is e'er unacceptable because:
  • it causes suffering to animals
  • the benefits to human beings are not proven
  • any benefits to human beings that animal testing does provide could be produced in other ways

Impairment versus benefit

The example for animal experiments is that they will produce such great benefits for humanity that it is morally acceptable to harm a few animals.

The equivalent case against is that the level of suffering and the number of animals involved are both so high that the benefits to humanity don't provide moral justification.

The three Rs

The three Rs are a set of principles that scientists are encouraged to follow in order to reduce the impact of enquiry on animals.

The iii Rs are: Reduction, Refinement, Replacement.

• Reduction:
• Reducing the number of animals used in experiments past:
  • Improving experimental techniques
  • Improving techniques of data assay
  • Sharing data with other researchers
• Refinement:
• Refining the experiment or the way the animals are cared for and then equally to reduce their suffering by:
  • Using less invasive techniques
  • Better medical intendance
  • Better living conditions
• Replacement:
• Replacing experiments on animals with alternative techniques such as:
  • Experimenting on jail cell cultures instead of whole animals
  • Using computer models
  • Studying human being volunteers
  • Using epidemiological studies

Drug condom

Beast experiments and drug safe

Scientists say that banning animal experiments would mean either

• an end to testing new drugs or
• using man beings for all safe tests

Animal experiments are not used to show that drugs are safe and constructive in human being beings - they cannot exercise that. Instead, they are used to help decide whether a particular drug should be tested on people.

Animal experiments eliminate some potential drugs as either ineffective or too unsafe to utilize on human beings. If a drug passes the animate being test it's then tested on a small human group before large scale clinical trials.

The pharmacologist William D H Carey demonstrated the importance of creature testing in a letter to the British Medical Journal:

We have 4 possible new drugs to cure HIV. Drug A killed all the rats, mice and dogs. Drug B killed all the dogs and rats. Drug C killed all the mice and rats. Drug D was taken by all the animals upwardly to huge doses with no sick consequence. Question: Which of those drugs should we requite to some good for you young human being volunteers as the commencement dose to humans (all other things existence equal)?

To the undecided (and non-prejudiced) the answer is, of course, obvious. It would also be obvious to a normal 12 year erstwhile child...

An alternative, acceptable answer would exist, none of those drugs because even drug D could cause impairment to humans. That is true, which is why Drug D would be given as a single, very small dose to human volunteers under tightly controlled and regulated conditions.

William DH Carey, BMJ 2002; 324: 236a

Are creature experiments useful?

Are animal experiments useful?

Animal experiments just benefit human beings if their results are valid and can be practical to man beings.

Non all scientists are convinced that these tests are valid and useful.

...animals have non been as critical to the advancement of medicine equally is typically claimed by proponents of animal experimentation.

Moreover, a slap-up bargain of fauna experimentation has been misleading and resulted in either withholding of drugs, sometimes for years, that were subsequently constitute to be highly beneficial to humans, or to the release and utilize of drugs that, though harmless to animals, have actually contributed to human suffering and death.

Jane Goodall 'Reason for Hope', 1999

The moral status of the experimenters

Animal rights extremists oftentimes portray those who experiment on animals as being so roughshod as to have forfeited any own moral standing.

Merely the argument is nearly whether the experiments are morally right or wrong. The general moral character of the experimenter is irrelevant.

What is relevant is the ethical approach of the experimenter to each experiment. John P Gluck has suggested that this is often lacking:

The lack of ethical self-examination is common and generally involves the denial or abstention of fauna suffering, resulting in the dehumanization of researchers and the ethical degradation of their research subjects.

John P. Gluck; Ideals and Behavior, Vol. one, 1991

Gluck offers this advice for people who may demand to experiment on animals:

The apply of animals in enquiry should evolve out of a potent sense of ethical self-examination. Upstanding self-examination involves a careful self-assay of 1'due south ain personal and scientific motives. Moreover, information technology requires a recognition of fauna suffering and a satisfactory working through of that suffering in terms of one'south ethical values.

John P. Gluck; Ethics and Behavior, Vol. 1, 1991

Fauna experiments and fauna rights

The issue of animal experiments is straightforward if we accept that animals have rights: if an experiment violates the rights of an animal, then it is morally wrong, because information technology is wrong to violate rights.

The possible benefits to humanity of performing the experiment are completely irrelevant to the morality of the case, because rights should never be violated (except in obvious cases similar self-defense force).

And as one philosopher has written, if this means that in that location are some things that humanity volition never be able to acquire, then be it.

This bleak result of deciding the morality of experimenting on animals on the basis of rights is probably why people always justify animal experiments on consequentialist grounds; by showing that the benefits to humanity justify the suffering of the animals involved.

Justifying fauna experiments

Those in favour of animal experiments say that the good done to human being beings outweighs the harm washed to animals.

This is a consequentialist statement, because information technology looks at the consequences of the actions nether consideration.

It can't exist used to defend all forms of experimentation since there are some forms of suffering that are probably impossible to justify even if the benefits are exceptionally valuable to humanity.

Ethical arithmetic

Brute experiments and ethical arithmetics

The consequentialist justification of animal experimentation tin be demonstrated by comparing the moral consequences of doing or non doing an experiment.

This process can't be used in a mathematical fashion to help people decide upstanding questions in do, but it does demonstrate the issues very clearly.

The bones arithmetic

If performing an experiment would cause more harm than non performing it, then it is ethically wrong to perform that experiment.

The damage that volition result from not doing the experiment is the upshot of multiplying 3 things together:

• the moral value of a human existence
• the number of human being beings who would have benefited
• the value of the benefit that each human being won't become

The harm that the experiment volition cause is the result of multiplying together:

• the moral value of an experimental creature
• the number of animals suffering in the experiment
• the negative value of the impairment done to each animal

But information technology isn't that elementary because:

• it's virtually impossible to assign a moral value to a existence
• information technology's near impossible to assign a value to the harm done to each private
• the damage that will exist done by the experiment is known beforehand, but the benefit is unknown
• the harm done by the experiment is caused by an activity, while the impairment resulting from not doing it is caused by an omission

Sure versus potential harm

In the theoretical sum in a higher place, the damage the experiment will do to animals is weighed against the impairment done to humans by non doing the experiment.

But these are two conceptually different things.

• The damage that will be done to the animals is certain to happen if the experiment is carried out
• The harm done to homo beings by non doing the experiment is unknown considering no-one knows how probable the experiment is to succeed or what benefits it might produce if it did succeed

So the equation is completely useless every bit a manner of deciding whether information technology is ethically adequate to perform an experiment, because until the experiment is carried out, no-i can know the value of the do good that it produces.

And there's another factor missing from the equation, which is discussed in the next section.

Acts and omissions

The equation doesn't deal with the moral difference between acts and omissions.

Most ethicists think that we have a greater moral responsibility for the things we do than for the things nosotros neglect to do; i.e. that it is morally worse to exercise harm by doing something than to do impairment by not doing something.

For case: we recollect that the person who deliberately drowns a child has done something much more incorrect than the person who refuses to wade into a shallow pool to rescue a drowning child.

In the animal experiment context, if the experiment takes place, the experimenter volition carry out actions that harm the animals involved.

If the experiment does not take place the experimenter will not practise anything. This may cause damage to homo beings considering they won't benefit from a cure for their disease because the cure won't be adult.

So the acts and omissions argument could lead u.s. to say that

• it is morally worse for the experimenter to damage the animals by experimenting on them
• than it is to (potentially) harm some human beings by non doing an experiment that might find a cure for their illness.

And and so if we want to continue with the arithmetic that we started in the section above, nosotros need to put an additional, and different, gene on each side of the equation to deal with the different moral values of acts and omissions.

Other approaches

Other approaches to animal experiments

One writer suggests that we tin can cut out a lot of philosophising about animal experiments by using this test:

...whenever experimenters claim that their experiments are important enough to justify the employ of animals, we should inquire them whether they would be prepared to employ a brain-damaged human being at a like mental level to the animals they are planning to use.

Peter Vocalist, Creature Liberation, Avon, 1991

Sadly, in that location are a number of examples where researchers have been prepared to experiment on human beings in ways that should not have been permitted on animals.

And some other philosopher suggests that information technology would anyway exist more than effective to inquiry on normal man beings:

Whatever benefits animal experimentation is thought to hold in store for us, those very aforementioned benefits could exist obtained through experimenting on humans instead of animals. Indeed, given that problems be considering scientists must extrapolate from animal models to humans, one might recollect there are proficient scientific reasons for preferring human subjects.

Justifying Animal Experimentation: The Starting Signal, in Why Animal Experimentation Matters: The Utilize of Animals in Medical Inquiry, 2001

If those human subjects were normal and able to give gratuitous and informed consent to the experiment then this might not be morally objectionable.

Proposed EU directive

Proposed Eu directive

In November 2008 the European Union put forward proposals to revise the directive for the protection of animals used in scientific experiments in line with the three R principle of replacing, reducing and refining the use of animals in experiments. The proposals have three aims:

• to considerably improve the welfare of animals used in scientific procedures
• to ensure fair contest for industry
• to heave enquiry activities in the European Matrimony

The proposed directive covers all alive non-man vertebrate animals intended for experiments plus certain other species likely to experience hurting, and too animals specifically bred so that their organs or tissue can exist used in scientific procedures.

The master changes proposed are:

• to brand it compulsory to carry out ethical reviews and require that experiments where animals are used be subject to authorisation
• to widen the scope of the directive to include specific invertebrate species and foetuses in their concluding trimester of development and also larvae and other animals used in basic research, education and training to ready minimum housing and care requirements
• to require that only animals of second or older generations be used, subject to transitional periods, to avoid taking animals from the wild and exhausting wild populations
• to state that alternatives to testing on animals must be used when available and that the number of animals used in projects be reduced to a minimum
• to require member states to improve the breeding, adaptation and care measures and methods used in procedures then as to eliminate or reduce to a minimum any possible pain, suffering, distress or lasting harm caused to animals

The proposal also introduces a ban on the use of cracking apes - chimpanzees, bonobos, gorillas and orangutans - in scientific procedures, other than in infrequent circumstances, but there is no proposal to stage out the apply of other non-homo primates in the immediate foreseeable future.
