16 Integral Pros and Cons of Animal Experimentation

❶Many of those animals are purposely bred for the experiments being performed as well, which means millions of animals are at a higher risk of suffering from abuse or neglect in a field that is often poorly regulated.

All mammals have the same essential internal organs, and these all fall victim to the same general maladies, such as heart disease and various cancers. For these reasons, scientists can confidently apply the results of a panoply of medical experiments on animals to human beings and be more confident when it's time to experiment on humans directly in clinical trials.

One of the leading arguments against animal testing is that it is simply a waste of scientific energy and resources, because the results of tests done on other species often cannot be reliably extrapolated to humans. For example, in a study at the Mayo Clinic by David Wiebers and his colleagues aimed at identifying drugs to treat ischemic stroke, the researchers found that 25 compounds that reduced the damage done by such events in cats, rodents and other animals had no beneficial effect whatsoever in people.

Unfortunately, the world of animal experimentation is rife with examples such as these. As technology moves forward, there is less and less need for animal experimentation. Human genes cloned into microorganisms can yield more specific toxicology results, for example, than simply administering toxins to animals. While much scientific research cannot be adequately done without animals, commercial safety testing, such as by cosmetics companies, is increasingly being done without the use of animals.

Meanwhile, improving the well-being of laboratory animals, such as providing an "enriched environment" for rats rather than keeping them isolated in traditional lab cages, can do much to ease the suffering of animals used in research. Some nations have an average life expectancy of over 80 years.

In comparison, a mouse has a lifespan of years, allowing researchers the opportunity to study through research and experimentation how something may affect the life cycle. Any long-term research involves mice and rats because of this unique aspect to the research. There are protections in place for the animals. Although animal research may have ethical concerns, the US has regulated its practice since Veterinarians are required to inspect the living conditions of the animals.

Committees must approve animal research and be held responsible for the humane treatment of each animal. Access to food and water is mandatory, as are shelters that follow minimum sizing standards.

Many of the items that are tested are never used. Animal testing may provide safety benefits for new products, but some of the items that are tested will never be used. That means animals will likely be sacrificing their lives to determine the safety of a product that a human will never even know was being developed.

With no direct societal benefit produced, what is the benefit of an animal suffering from the testing process? It can be an expensive practice. Caring for an animal requires a large investment. Some of the animals that are used for testing are bought at auction or taken from the wild, which brings additional costs into the process. Now multiple those costs over an entire laboratory and the cost of animal research becomes very high, very quickly.

It may not offer valid results. That means animal research can be more unreliable than even researchers claim it may be. Several drugs have passed animal testing, but have been found to be harmful to humans. Nearly vaccines for HIV showed potential in primates, but failed in humans. That means the results that animal research can produce may not even be valid. Many facilities are exempt from animal welfare laws. That means there are more than 20 million animals who could be at a high risk of abuse or neglect in the name of research.

There are a good number of animal research opponents who are primarily against animals used in cosmetics testing, but not against using animals for testing with human health benefits. The most significant research today using animals pertains to diabetes and cancer using primarily mice.

Secondarily, rats, pigs, and sheep are used. Birds and fish are used less frequently. The animal which shares the most similar patterns for diabetes is a cat; cats who become overweight do indeed become predisposed to the same kind of diabetes that humans do in the same situation.

In addition, animals have similar enough bodily constitutions to make the comparisons relevant and effective. If an animal is chosen for a particular line of research, its DNA structure has been determined to be similar to humans. In this way, humans may be prevented from the harms that are caused to the animals during the testing. The animal tests serve as a precursor to the commencing trial tests done on humans. Also, if the research conducted is beneficial to humans, it may well be beneficial to animals.

If a cure for a condition is discovered, the animal reaps the benefits of the cure as well. Through animal testing, drugs have been developed to treat human and veterinary ailments. Using animals in research is a costly methodology. Often it is not even possible without the companies or organizations asking for outside funding from third parties.

The costs of feeding, housing, caring for, and treating the animals must be considered, as well as the price of the animals in the first place.

Pros of Animal Research To begin, research using animals may lead to new medications being discovered. Examples of medications that have been the result of animal testing are Penicillin, several asthma treatments, cancer and HIV drugs, vaccines, antibiotics, and insulin.

Pros of Animal Testing. To decide whether animal testing is beneficial or not, it is best that you start learning its positive sides first like the following: Treatments Developed Have Saved Lives Animals are the most common subject of medical testing. This includes new drugs as well as possible cures for many different medical problems. List of Pros of Animal Experimentation. 1. Contributes to many cures and treatments that save many human lives The majority of the medical breakthroughs that have happened in the last years were direct results from animal research and experimentation, according to .

An example of this issue is aspirin. It is a dangerous product for animals to have, but think of the millions of lives that have been improved or saved because of the drug. Insulin causes animal birth defects, but it saves lives every day. That is the reality of animal research. The pros and cons of animal research will always be controversial. On the contrary, animal research ethics and the integrity and morality of such tests have been questioned by environmentalists. Pros PETA (People for the Ethical Treatment of Animals) supporters will stand in unison against the support of animal testing.
