Against animal testing

Animal testing is unreliable.

- Animal tests do not reliably predict results in human beings:

 94% of drugs that pass animal tests fail in human clinical trials.
 Out of 93 dangerous drug side effects, only 19% could have been predicted by animal tests, a
recent study found

- Animals are very different from human beings and therefore make poor test subjects.

 The anatomic, metabolic, and cellular differences between animals and people make animals
poor models for human beings. Paul Furlong, Professor of Clinical Neuroimaging at Aston
University (UK), states that “it’s very hard to create an animal model that even equates closely
to what we’re trying to achieve in the human.”

- Drugs that pass animal tests are not necessarily safe.

The 1950s sleeping pill thalidomide, which caused 10,000 babies to be born with severe deformities,
was tested on animals prior to its commercial release. Later tests on pregnant mice, rats, guinea pigs,
cats, and hamsters did not result in birth defects unless the drug was administered at extremely high
doses. Animal tests on the arthritis drug Vioxx showed that it had a protective effect on the hearts of
mice, yet the drug went on to cause more than 27,000 heart attacks and sudden cardiac deaths before
being pulled from the market.

Alternative counter argument: Computer models, tissue and cell cultures, and a number of other non-
animal related research methods are used today in biomedical research. However, animal testing
remains a neccesity. For example, blindness cannot be studied in bacteria and it is not possible to study
the affects of high blood pressure in tissue cultures.

The living system is extremely complex. The nervous system, blood and brain chemistry, gland and
organ secretions, and immunological responses are all interrelated, making it impossible to explore,
explain, or predict the course of diseases or the effects of possible treatments without observing and
testing the entire living system of an animal

2. For animal testings

Animal testing contributes to life-saving cures and treatments.

The California Biomedical Research Association states that nearly every medical breakthrough in the last
100 years has resulted directly from research using animals. Animal research has contributed to major
advances in treating conditions such as breast cancer, brain injury, childhood leukemia, cystic fibrosis,
multiple sclerosis, tuberculosis, and more, and was instrumental in the development of pacemakers,
cardiac valve substitutes, and anesthetics.

Take measles vaccine which used animal testing for example. Before the vaccine was invented in 1963,
nearly every kid on earth contracted it at some points and about 135 million people died a year bcz of
measles Measles vaccination resulted in a 73% drop in measles deaths. So whithout animal testing then
there would now still be millions of people die each year because of cancer.

It is totally normal and legitimate goal of humans to live healthily. You may say this method of
experimenting is killing animals but if we have to choose between humans’ life and animals’life, what
would be a wiser choice. Is it more humane to put the wellbeing of other species first rather than that of
your own fellow humans?
