@aperson,
The whole is "when is an embryo alive?" question is a big factor in the embryonic stem cell research controversy. I can not easily prove that the embryo IS alive without bringing in the Bible, which I don't know if you believe. Concerning the debate about whether stem cell research is ethical, I do tell you that each of us is special from the second we were conceived. We each had many things programmed into us for the future, such as the way we were going to talk, look, act, and what our talents were going to be. Even if you don't think that someone isn't alive until they leave the womb, we must consider the future for an unborn baby. Later, it will go on to have a life like ours. But what if it was used for stem cell research? Think about that. YOU could've been used for stem cell research. But you weren't, and that's why you are here today, reading this. An embryo used for SCR (stem cell research) is dead before it had a life. That is why embryonic SCR is so cruel. My point is that it doesn't even matter WHEN you believe the exact moment that someone becomes alive is, because an embryo is a human. Yes, a small human. Small indeed. But as Dr. Suess said, "A person's a person, no matter how small." Yes, yes, an embryo is a person. It just hasn't left the womb yet. And sacrificing this person for science, even if it is for the sake of another person, is wrong. Look back in history. Mayans and Aztecs sacrificed humans to please spirits, their gods, or the dead. (The following statement is said in all due respect:) you have to admit that this is crazy and obviously not right. Why kill an innocent person (the one sacrificed) for the life of another ( the people sacrificing)? This can be applied to stem cell research: why kill an innocent person (an embryo) for the life of another (the person with a disease)? And the funny thing is, umbilical cords and induced pluripotent stem (iPS) cells can be used for the same purpose as embryos WITHOUT sacrificing an unborn child. Of course, you may argue that embryos are better and cannot be so easily replaced. But in fact, iPS cells are incredibly easy for scientists to make. The only problem is that they are still researching and experimenting with iPS's and so they aren't ready for use yet. But until then, umbilical cords can be put to use! It is fact that 4.3 births occur per second (371, 163 per day). Also, there is one umbilical cord per birth. Think about that. Umbilical cords are very common. Why shouldn't THEY be used in stem cell research?
I am NOT against stem cell research. I am against EMBRYONIC stem cell research. Embryonic SCR should not be allowed. It is destructive and completely not ethical. Embryos are also replaceable, and I am all in favor of the new phase in the stem cell field: iPS's.
