Why is the use of embryonic stem cells controversial?

Stem cell therapies are not new. Doctors have been performing bone marrow stem cell transplants for decades. But when scientists learned how to remove stem cells from human embryos in 1998, both excitement and controversy ensued.

The excitement was due to the huge potential these cells have in curing human disease. The controversy centered on the moral implications of destroying human embryos. Political leaders began to debate over how to regulate and fund research involving human embryonic stem (hES) cells.

Newer breakthroughs may bring this debate to an end. In 2006 scientists learned how to stimulate a patient's own cells to behave like embryonic stem cells. These cells are reducing the need for human embryos in research and opening up exciting new possibilities for stem cell therapies.

I recommend you to try analyzing this excerpt in order to compile your own response towards the depicted situation. As for me, there is one stated truth: if someone is really wise and assured that his sphere of occupation is reasonable , this person would never persuade people to believe him/ her and stand on his/her side, because this person does not have doubts about that.
