Title: The Ethics of


1
The Ethics of Animal Research
2
Animal Testing
  • Previously we looked at the use of animals in
    spaceflight to further our understanding of the
    space environment.
  • The use of animals in scientific testing has
    always been, and will continue to be a
    controversial subject.

3
Animal Testing
  • While controversial, it is an unavoidable fact
    that animal research has allowed the development
    of medicines and vaccines, surgical techniques
    and advanced scientific understanding in many
    areas.

4
Animal Testing
  • It is estimated that between 50 and 100 million
    animals are used in research each year.
  • Some are purpose bred for testing but many are
    still caught in the wild.

5
Measuring Pain and Suffering in Animal Testing
  • The U.S. Department of Agriculture defines a
    painful procedure as one that would reasonably
    be expected to cause more than slight or
    momentary pain or distress in a human being to
    which the procedure was applied
  • Do you think this is a valid way to measure
    suffering in animal tests?

6
Measuring Pain and Suffering in Animal Testing
  • In the UK experiments are classified as mild,
    moderate or substantial in the amount of
    suffering they cause an animal.
  • A fourth category of unclassified is used when
    the animal is anaesthetized but killed before
    regaining consciousness.

7
Measuring Pain and Suffering in Animal Testing
  • In December 2001 the breakdown of experimental
    licenses was
  • 39 mild
  • 55 moderate
  • 2 substantial
  • 4 unclassified
  • Does this seem a reasonable breakdown to you?

8
Is Animal Testing Morally Right?
  • The argument between pro-animal testing parties
    and opponents to animal testing hinges on whether
    it is ethical.

9
Is Animal Testing Morally Right?
  • Advocates for animal testing say
  • Human life has greater intrinsic value than
    animal life
  • Legislation protects all lab animals from
    cruelty or mistreatment
  • Millions of animals are killed every year for
    food, is medical research not a more worthy death
  • Few animals feel pain and are killed before they
    suffer

10
Is Animal Testing Morally Right?
  • Opponents to animal testing say
  • Animals have as much right to live as humans
  • Strict controls have not prevented some animals
    being abused, though such instances are rare
  • Deaths for research are unnecessary
  • Animals suffer while they are locked up and how
    do we know when they do and dont feel pain

11
The Three Rs
  • The guiding principles for the use of animals in
    research are the three Rs
  • Replacement Use alternative, non-animal methods
    to achieve the same scientific aim
  • Reduction Use statistical methods so that a
    smaller number of animals are required
  • Refinement Improve the experiments so that
    animals do not suffer

12
Ethical Dilemmas
  • British law requires that any new medicinal drug
    to be used on humans must undergo a substantial
    testing program including testing on at least two
    different species of live mammal.
  • One of which must be a large non-rodent.
  • This of course means that any company wanting to
    release a medical drug must, by law, undertake
    animal testing regardless of how they fell about
    it ethically.

13
Ethical Dilemmas
  • Animal researchers say it will be impossible to
    eliminate all animal tests but scientists are
    always working on ways to minimise the suffering
    of animals and to ensure as few animals as
    possible will be required.

14
Case Study Laika
  • Laika, a mixed bred dog recruited into the
    Soviet space program after being found on the
    streets of Moscow.
  • Laikas mission would make her the first creature
    to orbit the Earth in an attempt to study the
    prolonged effect of weightlessness on a living
    being.

15
Case Study Laika
  • Laika was 3 years old when she was launched on
    the Sputnik 2 spacecraft on November 3rd, 1957.
  • She was secured in a special pressurised capsule
    3 days before launch and provided with a high
    nutrition gel for food and water.

16
Case Study Laika
  • Laika experienced minimal ill effects during
    launch but her heart rate did rise to three times
    its resting rate and she appeared to be quite
    agitated, eventually calming down.
  • It appeared that weightlessness alone did not
    cause major changes to the vital physiological
    functions of a living creature.
  • This was good news for human spaceflight.

17
Case Study Laika
  • Cabin temperature begun rapidly climbing to
    unacceptably high levels.
  • Temperature control inside the capsule was
    failing.
  • Between 5 and 7 hours into the flight telemetry
    showed that there were no signs of life within
    the capsule.
  • Laika had died from stress and overheating,
    undoubtedly a painful and distressing death.

18
Case Study Laika
  • As the world began to learn of the second
    Sputnik, no word of Laikas death was released.
  • The Sputnik 2 capsule that carried Laika into
    orbit was not retrievable and it had been
    intended that Laika would die in orbit.
  • But at the time the world believed that Laika may
    be recovered.

19
Case Study Laika
  • Protests from animal protection groups began
    around the world.
  • On November 5th a newspaper article in the New
    York Times included a report from an unnamed
    Russian scientists that the dog could not live
    much longer.
  • Other articles talked about the importance of the
    information being learned by sending an animal
    into space.

20
Case Study Laika
  • On November 7th Soviet scientists were still
    claiming that Laika was in good health when she
    had in fact been dead for four days.
  • Eventually the truth of the dogs fate emerged
    and on November 11th the Soviets confirmed that
    Laika was dead.
  • The exact cause of Laikas death remained a
    mystery for decades.

21
Case Study Laika
  • The truth was not confirmed until 2002 when
    Russian scientists confirmed that Laika had died
    between 5 and 7 hours after launch due to heat
    and stress.
  • Russian scientist Oleg Gazenko who worked on the
    Soviet Space Program stated that the more time
    passes, the more Im sorry about it. We did not
    learn enough to justify the death of dog.

22
Case Study Laika
  • Laika became a hero to the Soviet people and
    captured the imagination of the world.
  • Her flight immediately proved the near term
    capability for human spaceflight.

23
Case Study Laika
  • The question of whether the sacrifice of Laika
    was justified for the progress of space
    technology is still debateable in the context of
    ethics of animal research.
  • Could the flight have been postponed until
    recovery of the capsule was possible?
  • The political climate and the tensions between
    the United States and the Soviet Union during the
    Space Race meant that the ethical
    considerations of the mission were not properly
    considered.

24
Case Study Discussion
  • Do you think the mission was justified?
  • How could the experiment have been improved?
  • Was the outcome of putting the first man in space
    a valid aim for sacrificing Laika?
  • Did the fact that the Russian scientists covered
    up Laikas death make the experiment more
    unethical?
