About 25 million vertebrate animals are used yearly in research, testing and education but it is unknown what purposes they are used for. The most common animals used in research (ordered from most to least frequent use) are mice, rats, birds, rabbits, guinea pigs, hamsters, farm animals, dogs, primates and cats. The experiment animals are purpose bred and are mostly obtained from class A dealers. When an experiment ends the majority of animals have already been killed or are euthanized afterwards. It is very rare that animals are adopted out or placed into a sanctuary afterwards. The Humane Society of the United States advocates an end to use animals in biomedical research that is harmful to the animals. Diseases that are artificially induced in animas in laboratories are never identical to those that occur naturally in humans which makes the testing pointless. Medical doctor Christopher Anderegg states that animal testing has also been found to make little to no contribution towards treatment of human patients.We have the potential to replace or reduce animal use so that the animals experience less suffering or physical harm and should take advantage of this so these defenseless creatures do not …show more content…
Circuses, zoos, and aquatic attractions are considered “fun”, “entertaining” , “artistic” and “cultural” but none justify the forcing of animals into confinement, to suffer and to die for our benefit. Animal circuses travel many miles to different sites and the animals are kept into confined areas during travel. Not to include the abusive training that is used on lions, tigers, elephants and domestic animals. Trainers inflict pain on these animals with whips and often leave marks onto them. Circus’ teach viewers nothing about natural animal behavior; the only thing they are taught is that it is acceptable to enslave these animals to do what we want. Using animals only for tricks and entertainment implies that the animals’ lives hold no value in their own right. Zoos are basically prisons for wildlife animals. Cages deprive animals from the opportunity to develop and fulfill their interests and basic needs. Many of these zoo animals suffer from zoochosis. Zoochosis describes meticulous behaviors such as swaying from side to side, head bobbing and pacing. Social animals such as elephants and giraffes are often forced to live alone in solid confinement. Wildlife animals’ social relationships and emotional relationships are destroyed while kept in captivity. Visiting a zoo is not a good way to view animals in their natural habitats; it is stunted and unnatural.
