There are some who claim that the government must allow fetal tissue and embryonic stem cell research because it could potentially save many adult lives.
However, there are many problems with this claim.
First, it must be noted that there are actually two different types of stem cell research: adult stem cell research and embryonic stem cell research.
While adult stem cell research does not involve the destruction of human embryos, embryonic stem cell research does .
Embryonic stem cell research requires that the living embryo be killed for its stem cells to be harvested and used. While human features are not yet developed on the embryo, this does not mean that the preborn life should be used in whatever manner a researcher sees fit.
Additionally, it is actually adult stem cell research that holds far more promise than embryonic stem cell research .
Kim Lehman, of the John Paul II Stem Cell Research Institute, has said that, “Embryonic Stem Cell research has not only ethical concerns, but safety concerns and the reason is because they are generically unstable and they cause tumors, where, in contrast, adult stem cell research is very promising and doesn’t have ethical concerns…” 
Even if embryonic stem cell research would lead to effective medicines for adults, one should be hard-pressed to find people who admits they believe innocent lives should be destroyed so they can prolong their own.
It is our duty to protect all human beings at all ages. Preborn human embryos are living and should be given equal protection as any other life.
