Stem cells can help enhance a persons life which is why there are many people who think that it is good to research about stem cells to help provide a longer life span. People may disagree with me because there are many ethnical reasons why people think that experimenting with stem cells are bad. This includes Catholics who think that experiment with stem cells is like intefering from a human being being born. Which is like killing a human being without even being born. This is because they believe (very religious catholics) that they can not wear protection while having sexual reproduction which means that every time they do it they make a baby. So if you reserach with stem cells its like taking a life away.
