Stem cell research is another ethical issue. Stem cells are cells from an early embryo that can become any type of cell like a heart, lung, liver, or skin cell. The reason people are researching these cells are because you can actually grow new tissues and organs to replace damaged ones. For instance, it may be possible to grow a new set of lungs for someone dying of lung cancer. The ethical issue with this type of research is that in order to get this type of stem cells you have to destroy an embryo so it will never grow into a person. Do you think this research should be done? Why or why not?
