The Pros And Cons Of Genetically Modified Animals

1245 Words5 Pages

This allowed for the understanding of emotional bonds in animals allowing generalisations to be made such as when animals are orphaned by their parents, they need to see one of the same species to survive. This is because the young animal with imprint with what they first see and therefore learn the characteristics and behavior needed for survival in the wild. Therefore, if this is the case then genetically modified animals would need to be around wild individuals of the same species to exhibit the same behavioral characteristics. This means that animals could not be simply created in a lab and then be expected to behave in the same way as an individual born in the wild. Following this, it would then be unjustified to create genetically modified …show more content…

They argue that this allows for greater control and objectivity than there would be is the experiment used humans. Also, humans and animals are highly similar physiologically therefore allowing for generalisations from animal experiments to be made to humans benefitting society. It was Rudolf Jaenisch and Beatrice Mintz in 1974 who produced the first genetically modified animal when investigating the process of tumours by implanting embryos in female mice which had been injected with the Simian virus 40 DNA (Jaenisch & Mintz, 1974). Using these GM animal’s scientists can study disorders in many aspects from neurological, immunological and inflammatory to cancers as well as developing effective treatments such as gene and pharmaceutical therapy (Bedell et al., 1997). GM animals are also used in the xenotransplantation. This is where living cells, tissues or organs are transplanted from a non-human source into a human. There are lots of people on the transplant list hoping for organs to become available and a lot die from such waits though xenotransplantation provides a substitute for human organs and ease the demand for organ supply. However, there is an issue with the choice of animal used. Chimpanzees and baboons are similar to humans however there is higher in the risk of cross-species infection according to XJ Meng et al. (1997). Pigs are a better choice their organs are similar in size to humans, they have large amounts of offspring which quick to reach maturity and are easily in a clean environment. On the other hand, according to XJ Meng (2003) pigs can carry endogenous retrovirus which could be difficult to eradicate. Therefore, due to such complications with xenotransplantation, the public still are too wary of its use to ease the current of shortage of organs successfully. GM animals are also used for agricultural

This risk not only affects the organ receiver but also everyone that comes in contact with the recipient “creating new and dangerous diseases” (par.17). The main problem with Xenotransplantation is that they use pigs which “harbor a variety of other known and unknown bacteria and viruses” (par.18) transferring into human DNA. No good is going to come from using a foreign organ in a human’s body since most likely the “recipient's immune system is suppressed” causing the organ to “be

The disease raises many scientific and ethical questions. When scientists are studying ethics of Xenotransplantation and consider new technology they overlook many basic questions. They also look over the broad question that raises risks and is difficult to evaluate and is very important to consider. The organ transmission also has many risks. Since transplant patients now have to use immunosuppressants, that raises a risk to the environment.

Organ transplant saves thousands of lives every year, and is arguably one of the most significant medical innovations of the past century. However, the demand for organs far outweighs that of the supply, with many people not being able to receive the lifesaving organs they need. That is where Xenotransplants come in; Xenotransplantation involves the transplantation of nonhuman tissues or organs into human recipients. This essay will look at whether Xenotransplantation should be allowed by exploring the negative aspects of the procedure. Interspecies organ transplant is an operation that has more risks than benefits and that’s not to mention the ethical point of view.

Doctors would then have to inject the body with immunosuppressive drugs, and the recipients would most likely have to take these drugs for the rest of their life, costing them hundreds of dollars (Joo, Kim, Kang, and Lee, 2010). In the end, my opinion on the subject has changed since I first began my research. I am now against the testing and research of Xenotransplantation, and would rather have scientists and doctors focus on ways on how to use human cells as a solution to the organ shortage, as I had mentioned in my personal

Bioengineering is deliberately modifying certain characteristics of an organism by changing its genetic makeup. It is commonly used all around the world, especially in the agricultural and medical fields. Recently however, there has been a new idea introduced. Scientists want to start modifying animals. This proposal is both morally and ethically wrong.

Xenotransplantation is a medical procedure that involves the transplanting of living cells, tissues or organs from one species to another. Xenotransplantation includes many different forms of animal to human transplants such as the transplanting of organs and cell which may include the transplanting of pigs neural and pancreatic islet cells, tissue transplants and bridging transplants. While the technology providing xenotransplantation gives hope to curing many fatal diseases it also carries potential health risks. The procedure also raises ethical issues about the treatment of animals. In New Zealand research into xenotransplantation has been underway and there are organisations that are for it and some that are against it.

Xenotransplant is the process of transplanting non-human organs or tissues, into a human body. To put it differently, it replaces the damaged organ in the human with a healthy organ from an animal. It can also involve the combining or transplant of body fluids, tissues and cells by having their cells come into contact with another species outside of the recipient 's body, also referred to as bridging transplants. This is seen during a liver dialysis when the recipients blood passes through a genetically modified pig liver as a temporary dialysis machine until the recipient receives a new human organ. This has been done since the 1900 's but most have failed due to the unawarness of the body 's immune system and its possibility to reject a

If the creation of organs is “playing God,” then the use of modern-day transplants should also be considered that because scientists and doctors are already prolonging life. Bioengineering is solely another, more innovative way of transplanting that turns out to be not as risky as traditional methods. Humans are always looking for ways of innovation, and this is the next big step. The evolution of technology should not be prohibited, but embraced. If one feels like this new step in science is not right, then that person does not have to participate.

Today, doctors use donors’ organs to treat patients, who are in need of organ transplants. The patient's body can reject the organ if the prescribed medication is not taken regularly. The whole procedure can be expensive and not affordable to everyone. If doctors could replace the defective organ with a new one, which is developed by replicating the original organ, the process could be cheaper and extend the life of the patient without any complications. “Stem cells could potentially be used to grow a particular type of tissue or organ if directed to differentiate in a certain way” (Medical News Today).

Organ transplantation was, and still remains, one of the most significant medical breakthroughs in recent medical history *Note that differing margins and spacing have been permitted. According to the Cockrell School of Engineering, an average of 20,000 Americans undergo life-saving organ transplants annually; such operations have effectively served to improve the well-being and health of its recipients. However, although the UNOS (The United Network for Organ Sharing) waiting list has the potential to save a large number of lives, twenty patients who fail to receive an organ die daily. The most promising solution to this deficit is xenotransplantation: a process in which live tissues, organs, and cells are transplanted from a donor animal

Most people think that xenotransplantation is the best thing that scientists have come up with because it will end the need for organs that we are at a loss of, but in fact, there is more to xenotransplantation than people realize. “Just over 15 years ago, Baby Fae became a household name when American doctors replaced her ailing heart with the heart of a baboon...20 days after the transplant... Baby Fae died.” (Knell 15). Due to the lack of information on xenotransplantation, and lack of knowledge about the diseases included, this family lost their child.

The impression of many is that the presence of the Holy Spirit is accompanied by activity and often, loud noise. The mental picture, created by the account of the first outpouring of the Holy Spirit in Acts chapter 2, comes to mind. The scripture tells what raucous effect the Holy Spirit on this group of people had. They became noticeably noisy. There was something different about this noise.

This essay will look more on the advantages and disadvantages of genetic engineering. Genetic engineering has some advantages. Firstly it allows for faster growth rate .Genetic engineering allows of plants or animals to be modified so their maturity can occur at a quicker pace outside of the normal growth conditions that are favourable without genetic changes as well .Secondly, it may also provide a cure for disease to improve health (apecsecadmin, 2014). Genetic engineering can be used to eradicate a number of incurable and deadly disease which could be done by identifying the genes that cause these disease, and manipulate them to prevent people from contracting these potentially deadly diseases.
