Animal testing causes horrific suffering to animals and should be illegal.
To begin with, animal testing should be illegal because testing produces negative effects on the animals. When locked up these animals suffer a tremendous amount of stress. The stress that most animal encounter in labs can affect the way experiments work, making the results meaningless. If under stress, they can have permanently raised concentrations of stress hormones, reduced concentrations of sex hormones, and compromised immune systems. These are variables that are uncontrolled and make the animals unsuitable for scientific research. Even though penicillin has been proven to save many human lives it kills cats and guinea pigs. Many people agree that “Many experiments are not painful to animals and are therefore justified.” (P.E.T.A. NP) The Animal Welfare Act, is the only U.S. law that governs the use of animals in laboratories. This act allows animals to be shocked, burned, isolated, starved, poisoned, forcibly restrained, addicted to drugs, and brain-damaged. (P.E.T.A. NP) No experiment, no matter how painful, is prohibited. Pain killers are not required. There are plenty of alternatives to testing available, but the law does not require that they are used. “A 2009 survey by researchers at Newcastle University found that mice and rats who underwent painful, invasive procedures such as skull surgeries, burn experiments and spinal surgeries were provided with post-procedural pain relief about 20 percent of the time.” (P.E.T.A. NP) Deaths through research are absolutely unnecessary. Therefore it is morally no different from murder. According to the Animal Welfare Report published by the USDA, research facilities are not required to report the number of rats, mice, or birds that are used in laboratories. Ironically, this group of animals represents an estimated 90% of the laboratory animal population. For all we know, all of these animals
