Cloning a human is a very new science, and I feel that not much research or time has gone into this subject matter for us to know what risks are involved when cloning. Who knows? we might clone to save a life, but what if it costs another life, or causes some irreversible damage?
If we started cloning humans, different problems could arise. If someone was cloned who had diseases that ran in the family, such as cancer or MS, they could pass those on to the clone. The person could also pass on negative emotions, such as aggression and rage. Cloning could also cost money that we should not spend, especially when people can just have a child.
While cloning humans does not transfer experiences and memories, it does copy a person's genetic code. This will cause many problems, most visibly affecting the justice system. When there are 2 or even more people out there with the same DNA, it would make DNA testing as evidence to convict someone of a crime unreliable. Just think of all the crimes that are solved, and the criminals convicted, by use of DNA evidence.
Cloning and biotech in general are fraught with potential safety issues. I think that we will need adequate oversight both for safety and ethics. All new technologies can be dangerous in the wrong hands. That said, I do not think that we should stop the research - just be careful about it.
On the issue of safety, clearly a procedure to clone humans would be risky. A first-order problem would arise from the moral hazard the medical team undertaking the procedure would inherit. All of a sudden, they, and not nature, are responsible for the clone entity. That is a responsibility that would normally only be encumbered on the parentage.
Safety would be in peril if full humans were to be cloned. Every country or political group would eventually have access to this science and could clone and replace people in power anywhere to make sure their own agenda is followed. Identities would be next to impossible to prove since the clone would have the same DNA and finger prints as the original person.
There would be safety problems as a result of trying to clone human beings because there hasn't been enough scientific research into human cloning. It is one thing to clone a sheep, but humans are a different animal altogether. There is far too much of a chance of something going wrong, and I think science is a very long way from actually cloning a person.
Given that human cloning is still a fairly unexplored arena, there is no way to know if this is a safe thing to do. There are many moral issues with human cloning, which has allowed little research to be done. Whether or not it is morally correct or incorrect, there is no real way to know if it is safe to do. Considering that only animal cloning has been successfully experimented with, we can have no idea of the long term physical or mental effects to a cloned person.
After Dolly, the sheep, was cloned, people thought that human cloning would be around the corner and were concerned. But there is a very real concern about cloning that is often forgotten. A cloned creature has shorter telomeres, a part of the DNA that is a factor on lifespan. I would not want to clone humans, because it would be unfair to the cloned being. The cloned person would not be identical to the person they were cloned from - environmental factors would be too different - but they would have a shorter life expectancy. That would be wrong.
Cloning of humans, should be watched for cases of mentality and breeding. Instable reproduction can cause detrimental effects for our own race as a whole, and even with manipulation a chance of stagnating it. Safety problems will be a thing to watch for.
Seriously, are we watching a little too many science fiction movies? Every bit of research done in this area could easily unlock the door to a new scientific breakthrough. It seems like people are always ready to jump out their doors with torches and pitchforks in hand. But, I can say, without a shadow of a doubt, that we're not going to have an issue with doppelgangers. Even if the situation required more security, it would be handled with the utmost efficiency.
I don't exactly know what "safety problems" could arise from human cloning that wouldn't also be safety problems when performing a heart transplant or delivering a baby. Certainly, some safety issues could occur. But, as to if that is a problem, I don't believe it would be, any more than it would be for any other medical or scientific procedure.
While it is difficult to foresee all the ramifications of human cloning, there is no reason to believe that it is more unsafe than other laboratory procedures. On the other hand, human cloning may offer promising solutions to problems, such as organ failure or other health issues, negating the minor safety issues that may arise.
This same issue has been raised before, concerning the creation of test tube babies with donor sperm and egg cells. Somehow, when something is done by standards which some consider unnatural, it is automatically labeled as dangerous by those who are ignorant of the processes and precautions taken. I would like to know what the specific safety concern is, to be honest. If a human is cloned correctly, they should walk, talk and function just as any other human. In fact, cloning offers some things that natural procreation lacks, such as controlled conditions, the ability to select the most desirable traits, and being able to weed out potential birth defects. The child born will still be as much of a blank slate as a natural born human, because there are more dangers in the nurturing stages, which last for years, than in the 9 months of gestation, at the beginning. A clone would be equal and carry the same potentials for good or bad, as influenced by those around them, as a natural human has demonstrated for hundreds of thousands of years, or that test tube-grown humans have demonstrated in the last three decades, themselves. Perhaps those opposing this associate "unsafe" with "evil", mistakenly.
Man is trying to recreate something that is done through nature. This has the potential to cause many issues, many of which we may not even be able to predict. An experiment gone wrong could create many safety problems to the person, the scientist, and the world.
In fact, cloning humans (or any other mammal) may result in LESS safety problems due to avoidance of certain genetic, natural mishaps. Additional safety is provided due to the sterile environment cloning would need; extremely reduced chance of infection or biological contaminations.
Cloning with stem cells has been used to create materials for transplants. Creating new humans is not a likely use of cloning. Stem cell therapy undergoes clinical trials to ensure safety and efficacy like any other medical procedure.
