Although some find embryonic stem cells unethical, supporting embryonic stem cell research will benefit humanity in many ways. While many support embryonic stem cell research, some people who oppose it say it is an unethical practice. According to these people, embryonic stem cells require the killing of a baby, human life is defined by rational beings, capable of rational thought or consciousness. To be rational, one must first have consciousness, the ability to think thoughts and feel pain. “For a fertilized egg, there is no consciousness and no history of consciousness either” (Stem). If abortions are allowed in the United States, why shouldn't embryonic stem cell research be allowed? Another claim against embryonic stem cell research is that it devalues ​​human lives. “Some argue that embryonic stem cell research will lead us to cloning technology” (Embryonic). Although embryonic cloning is a possibility, we already have the capabilities to clone, so cloning is an invalid argument. The final argument against embryonic stem cell research is that there are alternatives, such as adult stem cells. Although adult stem cells can be used, they will not be as effective. Embryonic stem cells are not only effective but also renewable. They can be grown in a culture where adult stem cells are extremely rare, if any. They are only found in mature tissues. Isolating these extremely rare cells is challenging and results in a high failure rate if not harvested correctly. “A major difference between adult and embryonic stem cells is their different capabilities 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 specific 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 must accept that their child will survive them. People suffer and die. If more research was done on embryonic stem cells, healing damaged hearts would be easier and more effective. Patients and families would not have to wait months or years to receive warmth to help their children, mothers, sisters or brothers. We have the ability and obligation to help countless people. As humanity, we have an obligation to help others in need. Supporting embryonic stem cell research can and will benefit humanity in many ways, from curing men and women with diseases around the world to helping us understand in depth how our cells work..
