Pros and Cons About Animals Testing

Pros and cons about animals testing

By: Evelize Fonseca Dantas

Researches on living animals have been practiced since at least 500 BC. The humans use the animals for applying scientific research as to develop medical treatments, for commercial purposes as cosmetics products and for pure scientific research as improve humans’ knowledge. They are conducted inside universities, medical schools, pharmaceutical companies, farms, defense establishments and commercial facilities that provide animal testing services to industry. It was esteemed in 2006 about 670,000 that 57 percent of the animals (not including rats, mice, birds, or invertebrates) were used in procedures that did not include more than momentary pain or distress. This practice is regulated to various degrees in different countries. However, some reporters allege that only a few scientists use painkillers with animals in testing. Unfortunately there is an enormous perceptual that do not do equal and it has been increasing over time. Although, it is a topic that brings many controversies into society. Some people defend that it is wrong and other ones argue that it is right.

The supporters of animal defend the animals as if they were their fathers. Their conception involves ground of morality and humanity. They affirm that a huge percent of animals are killed or discarded after bee used. Besides that others remain in jails and patients until die. They believe that animals deserve to live without disturbance, without suffering caused by man. They think it is not just what men do with them. The men use the power that they have in their hands to hurt and take advantage of these animals. Although animal testing generally costs an enormous amount of money, as the animals must be fed, housed, cared for and treated with drugs or a similar experimental substance. Moreover, some people argue that these tests are not significant and there are others who claim that some scientists have accommodated with these types of experiments, which does not have courage to invest in new ones keeping it in old practices without reason. There are many cheaper and faster alternative methods that produce more accurate information as include artificial human skin and robotic technology that can screen thousands of chemicals at once using cells grown in the lab. Others argue that the reaction of an animal to a drug is quite different than that of a human being. Therefore, they will not react to the drugs in the same form compared to their potential reaction in a natural environment. This argument further weakens the validity of animal experimentation. The other topics that can testify the failure in animals testing are: artificially inducing stroke in animals does not recreate the complex physiology that causes the natural disease in humans, which may develop over decades and artificially inducing in animals the underlying conditions that lead to human stroke does not replicate the processes that occur in humans.

As it was mentioned, many animals are used in these experiences, however, some of them are the most commonly used. For example, 20 million rats and mice are subdued experience a year. Mice are widely considered to be the best model of inherited human disease and share 99 percent of their genes with humans and it can be generated to order and can provide models for a range of human diseases. Rats are also widely used for physiology, toxicology and cancer research, but genetic manipulation is much harder in rats than in mice, which limits the use of these rodents in basic science. The cats are used in neurological research. Over 25,500 cats were used in the U.S. in 2000, around half of whom were used in experiments which, according to the American Anti-Vivisection Society, had the potential to cause pain and/or distress. The dogs are widely used in biomedical research, testing, and education particularly beagles, because they are gentle and easy to handle. They are used as models for human diseases in cardiology, endocrinology, and bone and joint studies, research that tends to be highly invasive, according to the Humane Society of the United States. The primates are used in toxicology tests, studies of AIDS and hepatitis, studies of neurology and behavior. By the other hand, the use of animal testing as a lucrative purposes as some beauty
