Stem cell controversy

The article "how fetal tissue is used in medical research" discusses both uses and ethical controversies of stem cell research. It goes through actual progress made, such as vaccines, and mentions possible treatments that could be derived from this research. It discusses legal changes that have occurred, either making it legal, illegal, or legal with numerous requirements. It shows both sides of the argument fairly well, telling why stem cells are used, the claims against it, the response to the claims, and the moral controversy between those who think an immoral means can not justify a good end and those who think it is completely justifiable. It shows both sides appeal to logos, such as how cure have been derived from stem cells and how there have been cases, or at least claims, in which planned parenthood employees have broken the law. It also shows their pathos in which those who support stem cell research mention how practically everyone benefits from it and those against it by saying how they think something that is absolutely wrong can not be justified even if it helps others.
