A
However, the idea of cloning humans still remains、 While many people feel that cloning human tissue, as for organs for transplant might be valuable, many others feel that cloning a whole human is unethical (不道德得).
From a moral standpoint, much has to do with how some reproductive clones are made、 Many believe that an embryo, even when simply fertilized sperm (精子) and egg is a human and thus should not be destroyed、 Experimenta-tion of embryos to produce clones often results in embryo death、 Further some feel that cloned embryos might be used specifically to harvest body parts and then killed、
Some further feel that the harvesting of stem cells from an embryo is also wrong, or that creating embryos for the purpose of harvesting stem cells is unethical、 Others ar-gue that stem cell research may point the way toward cu-ring diseases for which there is currently no cure、 It should be noted, however, that fewer people object to the idea of cloning a body part than cloning a human、
Others are concerned about the cloning of extinct or endangered animals、 In fact Michael Crichton's novel Ju-rassic Park dealt with this theme、 Especially since actual dinosaur DNA has been found recently, in enough abun-dance to clone, some scientists are concerned about the en-vironmental impact that could result from reproducing a long dead species、
In some countries, stem cell research has been stopped, when it involves cloning human embryos、 Other scientists research on the possibility of finding stem cells elsewhere, as in the umbilical cord(脐带) blood of newbo-rns、 It is suspected that some countries may be attempting to clone a whole human, but have not yet achieved this、
Though cloning is much in the news, it is still an im-perfect science with more failures than successes at pres-ent、 This suggests that scientists may not fully understand all the mechanisms(机制) involved in creating an exact copy of another organism、 With further research, such mechanisms may be understood and clear the way toward making clones、 Yet, doing so is likely to result in continued argument、
