As to Aristotle stated, non-human creature were viewed as living for the human’s interest. This was anticipated as the Great Chain of Being, where all life forms were represented as existing for the purpose of those forms higher within the chain, this infers that humans are of a higher rank. Therefore, those creatures were treated as contemptible and were produced to serve the people. In late 18th to the 19th century, a few reformers advocated anti-cruelty treatments that animals were being received, this created an emergence of the fight for animal authorities. Some people began realizing the brutal and unfair behavior that had been set on non-human creatures and hoped to give them the morality that they deserved, which made the topic of “animal rights” a huge argumentative topic. Non-human creatures are not as different from us as we think, so why do we treat them so unfairly and irrationally? We both are actually familiars. The Origins of Animal Exploratory Lab Testing: Animal testings was a method that had been used understand the human bodies and the capacity of organism in 500 B.C., before advanced technology was discovered. Many Roman physicians first used human bodies as their testing subjects but soon were forbidden by the Roman Law, which states that human bodies must not be kept captivated as testing subjects. The Romans created this law because they assumed that the disturbance that is made to a dead body was sinful and may anger the gods, which may result in tragedies to the country (O’Neill). During the early 500s BC, physician scientists such as Aristotle, Galen, and Rene Descartes operated procedures on animals to discover the functions of living organisms. They all explained their beliefs of to why they had only applied animals for these testings. Aristotle, an ancient Greek philosopher and scientist, assumed that animals lacked intelligence, therefore the notions of justice and injustice should not be certained to them. Galen, a Roman physician and philosopher, presumed that the vivisection of animals without sympathy and sorrow is a better method to understanding anatomy without breaking the Roman law of dissecting human cadavers. Rene Descartes, a French philosopher, assumed that non-humans cannot consciously sense pain nor suffer the same way as the human race (Background of the Issue). Thus, non-human subject laboratory experiments began in Rome and the cause of animal subject examination that are still going on in the modern day.The Harmful Actions That Impact Animals’ Lives: Due to the unthoughtfulness decisions that the homosapiens race made, animals had been having a difficult time surviving in the wild. According to Justin Worland’s article “Here’s How Many Trees Humans Cut Down Each Year”, 15 billion trees were cut down each year, which resulted in a decrease of 46% of the tree count since infrastructuring had began and 90% of native forests have been removed (Logging: Cutting Down Wildlife Habitats). This meant that the 70% of Earth’s land animals lose their habitat, food sources, and shelter. These animals, such as tree kangaroos, giant pandas, saolas, orangutans, and African forest elephants, will decrease in population growth (Living among the trees…, Population). Millions of those creatures are also terminated by humans for clothings and accessories, which is another factor to animal population decrease (Animals Used for Clothing). This may result in very extreme consequences such as a disruption in the food chain, which will trigger in limited food source. Also, trees produce oxygen in which humans need. Therefore, cutting down trees also restricts the humans’ oxygen sources.Large Numbers of the Animal Population that Were Terminated for Lab Testing: Over 25 million of creatures were used for the human body’s biology and medical research experimentation, product and cosmetic testing, and science education each year (Animal Testing, Harm and Suffering). These animals that are subjected to undergo these testings includes dogs, cats, ferrets, rabbits, pigs, sheep, monkeys, chimpanzees, and many others. Although many types of creatures are being tested, the majority of animals in laboratories are rodents and birds. Very few animals may be able survive the experimenting process but, they will eventually get executed after the studying is accomplished (Harm and Suffering). Pollutions: Not only the laboratorial purposes may harm the animal population, pollutions can also impact animal populations greatly (Population). There may be many types of pollutions that affects wildlife and ecosystems such as liter and light. Light may not be seem as much of an impact but scientist had studied and concluded that artificial lights have a greatly negative influence on nocturnal animals and may result in unnatural behaviors. Nocturnal animals are creatures who sleeps during the daytime and are active at night, such as owls. The unnatural lights disrupts and alters animals’ environment by turning night into day from the ultraviolet and infrared radiations given off of the unnatural lights. A research scientist named Christopher Kyba had stated that homosapiens had greatly changed the night animals’ environment from the creation of electrical composed lights. He explains that preys needed the darkness to camouflage and stay hidden from predators. Also, the glare from the artificial lights interferes with amphibians’ reproduction. Birds that migrate and predate by moonlight and starlights are also affected by the unnatural lights. Over millions of birds collides into buildings and towers each year due to the unnecessary lights that causes them to wander off towards dangerous areas. The artificial lights also confuses the seasonal schedules for birds to start their migration, some may migrate too early or too late. This resulted in missed ideal climate conditions for nesting and foraging (Light Pollution Effects on Wildlife and Ecosystems). Hunting: Hunting activities had became an inherently unequal sport over periods of time, which is a disadvantage and unjustifying to animals’ moral. Hunting is considered unfair because while the hunters have powerful weapons such as rifles, shotguns, and muzzleloaders, the mammals are defenceless, unguarded and vulnerable (Wild Animals). Also, a majority of hunters execute animals not for the sake of resource but instead, for the pleasure of power. Those hunters are mostly known as trophy hunters. Trophy hunters are hunters who view hunting as a wild game and the trophy of the game is the animal or part of the creature that can be used for display to represent the success of the chase. Hunting is also then turned into a contest where hunters have to compete and kill as many animal as they can in order to win. The injured animals are then left behind to die slowly in a painful death. The most common animals that are executed in trophy hunts are lions, boars, buffalos, rams, antelopes, elks, and rhinoceros. Trophy hunts, also known as canned hunts, are private or commercial trophy hunts where animals are raised or captured from the wilderness and released into a confined area to be hunted. Due to the fact that hunters hunt animals that would make the best trophy, the strongest members of the population are terminated, which result in weakening and decreasing the animal population (Carmody). Animal Entertainment: Animals are held imprisoned to amuse the human race. Creatures are placed in circuses, zoos, aquariums, dog fighting, horse racing, and bullfighting against their will in order to entertain human beings. Although circuses may seem colorful, fun, and cheerful, animals are silently suffering. Animals had to endure long distance travels in box without any climate control, abusive training process, and perform several time a day. Visitors who come to watch the animal performance never learn about the animals’ conditions. The animals were enslaved and caged in the circuses for about 96 percent of their lives and are forced to learn new tricks to perform so the circus owner can make a profit. During the trainings, the animals were disciplined by getting physical abused and shocked with electrical prods. In conclusion, this is how cruel animals are handled in the circuses (PAWS, Entertainment). Zoos are like animal prisons, where animals are caged for the visitors’ joyment. Animals are caged for life and lose control over their lives and the environment they live in. Before the Endangered Species Act in 1973, wildlife parks capture and caged endanger animals from their natural habitants and were merchandised throughout the continent (Exposed). Many zoo animals experience zoochosis. Zoochosis is a range of psychological problems associated with mammals that are held in prolonged captivity such as head bobbing and pacing (Entertainment). In conclusion, having zoos are like having the right to enslave animals and enforce that the non-humans are only alive for humans’ entertainment. Aquariums are another form of animal prisons but the only animals found in an aquarium are marine animals. These marine animals, such as fishes, dolphins, sharks, and octopuses are condemned to spend the rest of their lives in tanks for people to watch them. Like the other animal captive places, the marine animals are enslaved for humans’ amusement as well (Entertainment). Farm Factories: Farm factories are another factor which endangers animal lives. Farm factories are large industries which operates to raise large numbers of animals for resource. Within these farms, animals are not being treated well. For example, animals are being incarcerated, overcrowded and cramped in one area, indoor confined with poor air quality and unnatural lightings, neglect of sick and suffering animals, and abused (Factory Farms Abuse Animals). These horrible conditions that the creatures obtained also affect humans as well. Due to the misuse, overuse, and dependence on antibiotics that are fed to the creatures may create dangerous, drug-resistant strains of bacteria to spread among both people and animals. Also, the industries’ system contaminates the environment, polluting the water, land, and air in neighboring communities. In conclusion, farm factories are very harmful to both people and animals (Farm Animals Welfare). In conclusion, animals have been ill-treated by human beings since 500 BC. Humans manipulate animals for lab testings on medical, cosmetic, and human body biology uses, entertainment, and profit. Along with being unrightfully used for the people’s benefits, animals’ homes are taken away from them for building human’s buildings and roads. Human beings also impacted and disrupt animals’ ecosystems without realizing how much of an impact it may cost animals to survive. After what was being said in this paper, do you think animals should have their own rights as humans does? Do animals only live for the humans’ sake?
