The cloning of human beings can corrupt the natural foundations of childbirth, consanguinity, motherhood and fatherhood. A child can become a sister to her mother, a brother to his father or a daughter to his or her grandfather. The psychological consequences of cloning are also extremely dangerous. A human being, who came to being as a result of this procedure, can feel not like an independent person but only "a copy" of someone who lives or lived before. It should be also considered that experiments with human cloning will inevitably produce as "by-products" numerous unfulfilled lives and, most probably, the emergence of a numerous unsustainable posterity. At the same time, the cloning of isolated organic cells and tissues is not an encroachment on the dignity of the personality and in a number of cases has proved helpful in the biological and medical practice.
