There are thousands of people losing hope on a daily basis of receiving necessary organs that will prolong their mortal life. Scientists are working on the process of transplanting organs from animals to humans. Currently there are five times more patients needing organs than there are organs available (http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2005/09/10/nba10.xml&sSheet=/news/2005/09/10/ixhome.html). The concern of ethics may be brought up. Personally, I feel that if the patient is in such dier need and is willing to risk the chance of becoming infected with various animal viruses then the individual should be able to make that decision. However, my concern is whether this will lead to an increase in the cloning of animals in order to produce prime organs for humans. This is where science needs to draw the line. Research and development is key in any organization. In fact billions of dollars are spent each year in this category and we benefit greatly from that. Yes, I appreciate new innovations, but I do not think we should start altering animals in order to make a "preferred match" for a transplant patient.
