Controversial

So i was thinking we have not had a controversial blog topic in a while and since we dont have class i am missing the thrill of sharing and hearing feelings on controversial topics :). I am wondering if any of you know much about stem cell research and what your stance is on the subject. I recently learned a little more about it in my biology class and it really intrigues me. Is stem cell research "playing god" and "messing with human life", or is it a "positive scientific exploration" to help further and sustain human life? Let me know what you think.....
