I am sorry, I should explain myself. I am all for using adult stem cells, too. However, adult stem cells have been researched since the 60s and enryonic is still fairly new, the late 90s. It took a while to come up with results from adult stem cells, too. Embryonic stem cell research has not been given much of a chance yet and if we can do it without harming a fetus, then I am for it.
I do not think it is right to produce embryos only to destroy them. I had heard of procedures which would not destroy them. This is why I say that we would not be preventing lives. At times, fertility clinics have to get rid of embryos, and these may as well be used for research rather than thrown away. At one point, I had heard of the possiblity of using aborted fetuses. If people are going to abort, we may as well use the cells.
The reason that embryonic stem cell research could prove valuable is that they harvest them at one week of age, before any tissues have formed and it is a mass of cells. Therefore, they can use them for researching any type of tissue.
"Recently, Advanced Cell Technology, Inc. reported a technique to generate human embryonic stem cells using an approach that does not harm embryos. "http://www.stemcellresearchfoundation.org/WhatsNew/August_2006.html
