Normally therapeutic cloning is termed only as embryo cloning. This is not correct. Scientists do not copy embryos. They just take genetic material from a cell and put it into an empty egg cell. With this type of technology, they can develop nerve tissues, heart muscles as well as brain cells. Scientists believe that by cloning, any damage caused by illnesses can be repaired.
Cloning involves high risks. The first drawback with it is that it’s very expensive and also inefficient. There are certain cases that have been unsuccessful. For example, in 2001, scientists reported that they had cloned the first human embryo, however the only embryo that survived divided into only six cells. More than 100 nuclear transfer procedures could be required to produce one viable clone. Research shows that cloned animals have high rates of infection, tumor growth and low immune systems. Cloned mice live in poor health and die early. Clones have been known to die mysterious deaths like the first cloned Australian sheep was fit and healthy when it died and causes of death were not revealed even after autopsy.
Cloning is done not only for organs but also for an entire human body. Some people like Hitler and Saddam Hussein wanted human replicas of themselves. That’s creepy. To have someone with the same intellect, intelligence and personality as your own kills your individuality. Also if the actual Hitler died, a clone would still be moving around and that’s a scary thought. It’s also unethical as our bodies are sacred; we have no right to destroy any part of it intentionally. We cannot attempt to take nature into our hands. Lots of religious groups say that the male involvement in the process of reproduction becomes useless if cloning becomes successful, and that is not right. Also if this technology falls into the wrong hands, it can be used to perform criminal acts. Moreover, if done inefficiently, it can cause defects in the clone of a human.
