In 1997 a controversy came up to ban human cloning after a sheep named Dolly was successfully cloned. Dolly was created entirely out of cells taken from a full-grown adult sheep at the Roslin Institute in Scotland. {Ref: #1 & #3}.
People all over the world argue that cloning humans is wrong, and that humans should not be treated as guinea pigs. .
Since Dolly's arrival to this world, scientists have cloned mice, pigs, calves, and monkeys using new technologies. Now doctors and scientists want to perform these experiments on human beings. How dare they mess with Gods creation? Don't they realize that each human's life is unique, born of a miracle that reaches beyond any laboratory or science? Don't they value the life of a real person? People all over the world argue that cloning a human would be morally wrong. {Ref. #3 & #4}.
To clone is to make an exact copy of something or even someone. A clone is actually a group of genetically identical cells. Scientists through out the world have always had a fantasy of cloning a human being. This fantasy developed as early as 5000 B.C. when early humans discovered that if they plant seeds produced by the heartiest plants, the next crop would be a strong one. {Ref. #2 & #3}.
Even with all the discoveries that have followed since, experts believe that cloning is dangerous. There are too many unknown factors that could lead to negative effects on humans. Just by looking back at the creation of Dolly before she came to this world, scientists experienced many deaths of embryos and newborns before success was achieved. {Ref. #2}.
How many deaths should occur before a perfect human clone would walk this earth? The answer is none! If scientists can't go through the process without hurting anyone, they should not even consider the subject of cloning humans.
Cloning might also lead to the creation of genetically engineered groups of people for specific purposes, such as warfare or slavery.
