There are two distinct forms of cloning such as reproductive cloning (making copies of entire organisms) and therapeutic cloning (making copies of embryonic stem cells). With very rare exceptions, the vast majority of researchers and medical professionals are against the idea of reproductive cloning in humans. However, there is a growing popularity for the pursuit of therapeutic cloning since the promises of stem cell research are so enticing. As the result, some people think that both are unacceptable, others think both fine and some are in favour of one but not the other.
According to me, therapeutic cloning is fine whereas reproductive cloning is unacceptable.
Firstly, therapeutic cloning can be used to understand human biology. For example, scientists can do experiments based on therapeutic clones of human organs. In addition, they could grow to repair a serious burn, grow new heart muscle to repair an ailing heart, grow new kidney tissue to rebuild a failing kidney.
Secondly, reproductive cloning is unacceptable. The reason is that by cloning an organism, scientist just copy the organism. When there are lots of copies for an organism, genetic differences cannot be seen between those copies. In the long term, those organisms can cause genetic illnesses because of the fertilization between those clones. For this reasons, reproductive cloning shouldn't be used to protect the genetic diversity between the organisms whereas therapeutic cloning can be used for experiments and growing human organs for illnesses.
