Stem cell research is one such area where the world does not have a unanimous decision and where some people are against it, some are in favor of it and others simply don’t know what to do. The controversy associated with embryonic stem cell research is with regards to the destruction of the embryo when cells are extracted and though embryos are being used for in-vitro fertility treatment there are a number of people who are opposed to stem cell research on the basis that embryos are just the start of human life. People who are for embryonic stem cell researches state that embryo should not be given the same importance as the fetus and though they agree that embryos are being destroyed but they further say that the benefits offered are far more when compared to the downside. People who oppose embryonic stem cell research are pro life campaigners who believe that destruction of embryos leads to the destruction of human life and these people are generally against embryonic stem cell research rather than stem cell research. There are also some people who are against stem cell research since they feel that it would lead to reproductive cloning. The controversy associated with stem cell research is expected to continue until and unless a proper consensus is reached on this issue.
