Should we ban human cloning? Arguments against cloning

Here are three reasons why we should say no to cloning - disadvantages:

1. Health risks from mutation of genes

An abnormal baby would be a nightmare come true. The technique is extremely risky right now. A particular worry is the possibility that the genetic material used from the adult will continue to age so that the genes in a newborn baby clone could be - say - 30 years old or more on the day of birth. Many attempts at animal cloning produced disfigured monsters with severe abnormalities. So that would mean creating cloned embryos, implanting them and destroying (presumably) those that look imperfect as they grow in the womb. However some abnormalities may not appear till after birth. A cloned cow recently died several weeks after birth with a huge abnormality of blood cell production. Dolly the Sheep died prematurely of severe lung disease in February 2003, and also suffered from arthritis at an unexpectedly early age - probably linked to the cloning process.

Even if a few cloned babies are born apparently normal we will have to wait up to 20 years to be sure they are not going to have problems later -for example growing old too fast. Every time a clone is made it is like throwing the dice and even a string of "healthy" clones being born would not change the likelihood that many clones born in future may have severe medical problems. And of course, that's just the ones born. What about all the disfigured and highly abnormal clones that either spontaneously aborted or were destroyed / terminated by scientists worried about the horrors they might be creating.

2. Emotional risks

A child grows up knowing her mother is her sister, her grandmother is her mother. Her father is her brother-in-law. Every time her mother looks at her, she is seeing herself growing up. Unbearable emotional pressures on a teenager trying to establish his or her identity. What happens to a marriage when the "father" sees his wife's clone grow up into the exact replica (by appearance) of the beautiful 18 year old he fell in love with 35 years ago? A sexual relationship would of course be with his wife's twin, no incest involved technically.

Or maybe the child knows it is the twin of a dead brother or sister. What kind of pressures will he or she feel, knowing they were made as a direct replacement for another? It is a human experiment doomed to failure because the child will NOT be identical in every way, despite the hopes of the parents. One huge reason will be that the child will be brought up in a highly abnormal household: one where grief has been diverted into makeing a clone instead of adjusting to loss. The family environment will be totally different than that the other twin experienced. That itself will place great pressures on the emotional development of the child. You will not find a child psychiatrist in the world who could possibly say that there will not be very significant emotional risk to the cloned child as a result of these pressures.

3. Risk of abuse of the technology

What would Hitler have done with cloning technology if available in the 1940s? There are powerful leaders in every generation who will seek to abuse this technology for their own purposes. Going ahead with cloning technology makes this far more likely. You cannot have so-called therapeutic cloning without reproductive cloning because the technique to make cloned babies is the same as to make a cloned embryo to try to make replacement tissues. And at the speed at which biotech is accelerating there will soon be other ways to get such cells - adult stem cell technology. It is rather crude to create a complete embryonic identical twin embryo just to get hold of stem cells to make - say - nervous tissue. Much better to take cells from the adult and trigger them directly to regress to a more primitive form without the ethical issues raised by inserting a full adult set of genes into an unfertilised egg.

    right now, I am writing a essay on why cloning is wrong. i am not focusing on the ethical views but more of the facts. it causes premature death, costs tons of money, has seen a lot of failure, the clones life will be awful, and it reduces a sense of individually among people. good points or no?any ideas for more points?

    1. kk ·

      you know that people are not cloning people that will live in today's society. they will be fetuses without a brain or a heart and as long as something is cloned with no defects it will have a perfect life (unless cloned from you). also, every early experiments experiences a lot of failures.

      the are plenty of argument against human cloning -especially humans -ranging

      from scientific issues,to the practicality of cloning to religious objection

  2. TheOwundian ·

    I read a lot of these comments and thought them to be very entertaining..

    Also I think cloning would be useful for things like replacing organs and other stuff.

    I think that it would be cool to have a brother or sister that was a clone of myself but I realize that would kinda be selfish and too late ( it would be weird having a younger version of yourself running around causing chaos) another reason having a cloned sister or brother would be that their personality might not be the same as yours and its not positive they will even get along with you. so I would be better off with my actual brother or sister. I do think cloning extinct animals would be awesome, as long as its not like Jurassic Park. Also if I had a clone I would not fear being replaced it because its a different person than me it just looks like me and if it somehow had the same mind as I did I probably wouldn't care who was the clone and who wasn't and same with the clone. Anyhow I believe it could be useful but is not necessary

    I THINK CLONING SHOULD NOT BE DONE BECAUSE IT COULD HURT OUR ENVIORMENT AND DO STUFF THAT WE REGULARLY DO NOT DO AND SOME GENE COMPLICATIONS COULD GO WRONG

    cloning is not ok

      Yes cloning is wrong but there is no reason to fight about it see some people are right and some people are wrong there is no right answer

    cloning should never be aloud by united nations and it should be totly band because it will have many disadvantages for exampel peopel can be created throgh cloning and they can be forced to fight against a country

    Its hard for me to believe that someone would do this...although there are definitely medical benefits to be gained this is not without consequence. I don't need a PHD in science to know that if you take something away from nature, you eventually have to give it back. What Im trying to say is that with cloning life, this earth and us as humans will lose our identity as a whole race.

    We humans are an amazingly resourceful species, but while this helped us to survive all sorts of devastations in the past we should stop at a certain point. Its part of the natural world as a human experience to being born, growing up and exploring the world. We should stop trying to cheat nature and bending rules that existed for ions to our own will.

    Remember guys that life is not cruel, its the people who try to control the natural process of life that make it cruel.

    Peace everyone

    The only reason that I think cloning is looked upon as a bad idea, because it would change the world as we know it it would break down the morals and values of normal religions and people themselves. People wouldn't know how to act towards religion anymore. It would have seemed they we have been lied to all these years just so that we could be taught right from wrong, good from the bad.

    All the people that say it is a lack of human respect and thinking thescientist will look at themselves as Co-creators, is all a shame. In my opinion they are trying to stop us fromfinding out that there is really nothing to believe in and that we did just come from dust. The catholics and other religions have that correct we did come from dust or should I say elements tea ting in such a way that it was perfect and life could thrive, but as people we see that as to big of a step and that it is imposibble. But it is not my friends somewhere else in the universe we are not alone. I promise you that. But this would be blasfomouse wouldn't it? Saying god did not put us on this earth and that humans were made just by sheer coincidence. Well get it through your heads because that's what happened! Lol... I will say that if we do clone a human and it acts the same as everyone else(it will be like teaching a baby all over gain yes of course)then it will prove that there is faulty in the Catholic and other religions. just think a world without religion (did you think of koas) because that's how it would be. Religion is a passifier to hale the human race and give it meaning, and a reason to work together. You all seriously aren't dumb enough to think it was real were you?? God and all the other ma in religions are creation story's and ways so that we can see life has a meaning and a higher purpouse but it doesn't we are just moving along in space like normal elements and particles of dust. You might say "well what about the big bang huh???" the truth is no one knows a DAMN thing about the big bang air how the universe got started get it through your heads. Religions are just a creation story to tell us how we magically came to be poof we are here. No that didn't happen! Cloning would prove every religion wrong and say god or whoever it is is not the sout create of life god would cease to exist and the world would turn to turmoil. This is my imput on the subject. I say if catholics are against cloning, then they are scared to be proven wrong. I challenge science and religion to go head to head on this and figure out once and for all if there is a god at all or gods science will provail trust me.

    To "In every advanced technology humans make there's an equal consequence it maybe be good or bad. Weigh things first, if cloning has more advantages than cons, then maybe it only means we have to go for it." I agree. Like when we were trying to learn about our world, and what it's made up of, we discovered the atom. In 1905, Albert Einstein wrote the mass-energy conversion equation. And Sir James Chadwick, a student and co-worker of Lord Rutherford, in 1932, discovered the third fundamental particle of the atom, the neutron. This would provide an ideal projectile for splitting the nucleus of the atom. These steps helped to create the atom bomb, even though the research was meant to further our knowledge of the universe. There's going to be people who turn something wonderful or helpful, into something destructive. But if we let this stop us, we will never move forward. Yes, cloning has 'bugs' right now, but in the future they'll be worked out. Cloning can help save lives. Why would you prevent that? To this question, don't explain it with religion, because I too, am religious, yet cloning, I feel, is not against religion. Give it a chance before you condemn an idea. Give cloning a chance to prove it's worth before you lash out in protest. Think about it. If it helps more than it harms, can it really be that bad?

      what if you clon something that can damage the world and might bring something that can kill people

  17. Trinity Heckathorn ·

    What are all of the cons of human cloning???

    1. alexis hills ·

      Here are some that i did find:

      1) Cloning would/will undermine individually and identity.

      2) Cloning would potentially pose a threat to human diversity and cause a deduction of genetics

    I think cloning is only good in the medical field for science reasons.
