Why is embryonic stem cell research controversial?

Answer 1

The stem cell controversy is the consideration of the ethics of research involving the development, use and destruction of human embryos.

The majority of the discussions around human embryonic stem cells center on two main points of contention: 1) what limitations should be placed on research employing these cells, and 2) is it morally right to destroy an embryo if it has the potential to cure countless numbers of patients?

Instead of using human embryos, some stem cell researchers are trying to create methods for isolating stem cells that have the same potency as embryonic stem cells.
