I will not state my opinion on this matter, just give you the views of both sides.
On side one, we have those who are for stem cell research, they want this because there are many diseases, such as cancer, that can be cured with this kind of research. This would be helpful because many people in the world suffer from this disease. We could save the human race.
On side two, we have those who are against it. They tend to take this side, because they do not think it is right to take the life of the embryo. It's not that they are against the research, and will usually support it if its taken from the bone marrow, or from the umbilical cord.
There are a few religious groups that endorse stem cell research, such as anti-christism, who try to bring about the end of the world by sinning en masse.
