Human cloning has been a major issue over the past decade or so, at the beginning we started to changed the structure of plants, etc like tomatoes because of the food sources, we made them immune to diseases so that they grew bigger and lasted longer. Nobody thought that was made, then the scientists managed to clone sheep the first to be called 'Dolly' but they did not want to stop there and they wanted to clone human beings. About that, there are many argument in the world today regarding the disadvantage of cloning.
People believe that cloning could be immoral, because some human characteristics are more important then a clones body. It could destroy human nature and the fact that cloning denies the 'Sanctity of Life'.
Besides that, cloning mammals is still a highly experimental technique. Scientists involved in cloning various mammals have reported many technical problems. A large majority of the clones die during gestation or soon after birth. Placental malfunction seems to be a major cause of death. Many of the surviving clones are plagued with serious physiological and genetic problems. During embryological development, cloned sheep, cows, pigs, and mice tend to become unusually large. Although some scientists suggested that human clones might not experience the problems encountered in cloned animals, the risks remains very high and quite unpredictable.
On the other sides, there are still a lot of benefit of cloning. Clones would be the best organ donors. Imagine your mother suddenly gets cancer in her kidneys and she needs to have a transplant. Assuming you love your mother and would do anything for her, you decide to be her donor. Then after the operation, her body rejects the new, foreign organ, and the kidney fails. The doctor says that the only way she would survive would be to find a kidney with the same type of tissue as her original, healthy tissue. The solution to your mother's problem and the answer to your prayers would be cloning. Because a clone is an exact copy, she would have no worries about her body accepting the organ or not. This would be the only way to save her.
In addition, infertile couples could have biologically related children. For years, couples everywhere have been facing problems of infertility, meaning they are unable to reproduce. Many of these unfortunate couples still want children, so they settle for adoption. The problem with that is that the kids are not actually blood related, and this leaves an empty hole in so many people's lives. With cloning, these couples could finally have children with their genes. They would be exact copies of one parent's DNA. Cloning is the perfect solution for making many people incredibly happy, and helping the human race grow.
In conclusion, there are more serious negative effect of cloning although its advantages can be detect. In my opinion, human should not be cloned. We have to face the nature – dead which should process by every human beings.
