Do the Causes Outweigh the Affects?

In the article," The Cons Of Stem Cell Research," Dr. Fran Manista asserts that the use of embryotic cells is hazardous to man down to every last, microscopic molecule in our bodies.  Firstly Dr. Manista points out the blatant ethical problems in the field of stem cells.  Also, he contends that the practice of these stem cells proves to be unstable.  Lastly, the research of stem cells is not thorough enough to prove the plausibility that it would be effective and healthy for humans; that the difficulty and making these suitable for the human body would be an extremely difficult affair to accomplish.

            Although the benefit of stem cells could be great, there would need to be human test subjects, for the plausibility of the testing to be proven.  And with no-one on the verge of wanting to risk their life for science, at the moment I believe that this research would something very difficult to strive for.  At this point in my research, the causes do not seem to out way the effects.  Also it would take hundreds, or even thousands of dollars to just produce a tiny amount of these cells, which we do not know may even be stable, in the long run, for our bodies.  Also, going to the ethical, moral side of the argument, is morally wrong to end the life of any human.  Life begins at conception; therefore these are all human beings.  Although one day, maybe this may cure many lives, does ending another curing life out way healing another?  Do the causes outweigh the affects?

Why Stem Cells?

There are many reasons to be excited about a topic so debated as this one.  The reason I was drawn toward this topic is one of great content and compassion.  Having people in my life who I know who have abused substances such as alcohol and tobacco and the effects that this has on the body, the effectiveness of stem cell research on the body proves that it may be able to help repair the tissues damaged in the acts of abuse.  I have seen first hand what happens to the people who take part in such acts and have seen how much differently they act after the many years of the continual behavior; especially memory loss.  With the new technology that stem cells has to offer, these destroyed parts of the brain or another other tissue in the body damaged for any other reason, can be repaired.  We could cure hundreds of diseases, cancer and even aids at one point.
