CLONING LIVING THINGS

I think that cloning humans is not necessary really because humans can reproduce themselves without some clones ;And one of the problems of cloning humans is that the humans that are cloned can not reproduce like the normal humans. To use the clonation correctly we have to put limits to do this things that are not so usefull even for the nature and also for the humans , im not saying that it is not great but i will give a suggestion and it is that when all the cloning animals or humans can reproduce and use it with animals in danger of extinction for that time , and i would say that dont use it on humans because we will contribute to the overpopulation in the planet earth. Other problem on cloning living things that can move is that there are possibilities that the human or the animal that is being cloned will be with 5 legs , 2 heads and some things like that. Is like technologybecause when it first used it is not so good but some years or months later you retry it and it is better than when you first use it , and this are some photos of the possibilities when the clonig goes wrong (this is natural)
