It's true that cloning could help produce a superior race, provide hope to those in need of an organ transplant and help people suffering from Parkinson's disease.
Parents could design their babies and decide on their IQ, talents and appearance ... soon enough, the whole human race would become superior and perfect. Ah, perfectionism. Each and every individual has unique features, strengths and weaknesses. No one is perfect.
That's why our society functions smoothly and orderly - each person takes up a role they are good at.
We communicate, co-operate and learn because the strengths of others can make up for our own weaknesses.
If everybody was perfect, imagine what our world would be like. Everyone would be isolated: they would achieve whatever goals they wanted on their own. Everyone would become selfish.
Moreover, a human clone is a human life, too. They think and have emotions like we do. How would they feel if they were produced as a substitute or for medical treatment?
