Although some believe that embryonic stem cells are unethical, supporting embryonic stem cell research will benefit humanity in many ways. While many support embryonic stem cell research, some people oppose it, saying it is an unethical practice. According to these people, embryonic stem cells require killing a child, human life is defined by rational beings, capable of rational thought or consciousness. To be rational you need to have a conscience, the ability to have thoughts and feel pain, for starters. “For a fertilized egg there is no consciousness or even history of consciousness” (Stem). If abortions are allowed in the United States, why shouldn't embryonic stem cell research be? Another charge against embryonic stem cell research is that it devalues ​​human life. “Some argue that embryonic stem cell research will lead to cloning technology” (Embryonic). Although embryo cloning is a possibility, we already possess the capabilities to clone, so cloning is an invalid argument. The final argument against embryonic stem cell research is that alternatives exist, such as adult stem cells. While adult stem cells can be used, they will not be as effective. Embryonic stem cells are not only efficient but also renewable. They can be grown in a culture where adult stem cells are extremely rare, if any. They can only be found in mature tissues. Isolating these extremely rare cells is challenging and has a high failure rate if not harvested properly. “One of the major differences between adult and embryonic stem cells is their different capacity in the number and type of differentiated cell types they can become” (Stem). Using adult stem cells we may never understand our development from conception... middle of paper... n years. Matching a human heart to a particular person is difficult. Most families describe the most difficult part of the heart replacement procedure as waiting for a compatible heart. Some people never find one and have to accept that their baby will survive. People suffer and die. If research on embryonic stem cells were more thorough, healing damaged hearts would be simpler and more effective. Patients and families should not have to wait months or years for treatment to help their children, mothers, sisters or brothers. We have the ability and obligation to help countless people. As human beings we have an obligation to help others in need. Supporting embryonic stem cell research can and will benefit humanity in countless ways, from curing men and women affected by disease around the world to helping us gain a deeper understanding of how our cells work..
