It's important to realize that cloning is just another way to make babies. A clone would be just like everybody else, except that they would happen to have the same DNA as the donor. This is already true of identical twins, who are naturally-occurring clones.
If we want to clone you, we would have to take a cell from you, pull the nuclues out of that cell, and insert it into a human egg cell whose original nucleus has been removed. (The technology to do this exists and is quite simple). We would then place that egg cell into the uterus of a surrogate mother, and nine months later she would give birth to a baby. The baby would have your DNA, and it would look an awful lot like you did as a baby, but it would be an independent person, with a completely different personality, and would of course continue to differentiate from you as it grew up under different circumstances than you did.
The study of epigenetics is making it clearer and clearer that DNA is not destiny; there are a lot of other factors involved in making you who you are.There is, or at least was, a company in California that would clone your cat or dog for you; they had a lot of problems with dissatified customers, because the cloned animal didn't have the same personality as the original pet. With the cats sometimes there was not a lot of physical resemblance either; things like how spots and blotches of color develop are epigenetic and/or fractal and are not the same in spite of the DNA similarities.
That said, I can't see any good reason to clone humans (or cats or dogs), there are already more of us around than the planet really needs.
Here's a link to an article that shows pictures of a couple of the cloned cats, so you can see what I mean:
I think it's going to be a fascinating but extremely challenging evolution to observe the biomedical ethics try to catch up with the science of cloning. I'm grateful that I won't be involved in trying to make the decisions and definitions that are going to be required.
Cloning of organs or tissues is something that I can see as potentially being very beneficial to human life. I find the possibility of cloning entire persons truly frightening. Even without cloning, science is coming close to being able to serve some of the purposes that cloning would serve - with all the ethical challenges of that process. Remember the book and subsequent movie "My Sister's Keeper"? The novel was fictional, but based on real medical possibilities...
I disagree with the idea of cloning humans. I am curious however about the ability to clone particular organs and tissues of an individual. If this is possible I think it would be of great benefit in fighting diseases such as cancer.
This seems like an open and shut issue, but I think it will become more complicated over time. At some point (we are very close to this technology) we will be able to clone individual tissues and organs. Imagine if your kidney transplant was made with one of your own kidneys, cloned from your own cells and DNA. No rejection drugs, no donor waiting list. There are a number of cloning tecnhologies that could dramatically increase our life expectancy and quality of life.
Inevitably, someone will try to clone a human altogether, which I don't support at all. We have a much more reliable and time tested method of making humans I tend to prefer.
From your post, it's clear that you are referring to cloning human beings. I do not support cloning people at all. My reason for this is that there is absolutely no good reason to clone people. When we clone animals, we might do it because A) there aren't enough of them -- like with an endangered species or B) because we want to replicate the qualities of a given individual (like a prize bull). Neither of these applies to people. We already have plenty of people with no prospect of running out. We have no reason to try to replicate individuals because we do not really prize people's physical attriubtes. Cloning would not create a person with the same personality and experiences, which are the things that really make a person important.
So, I see no benefit to this.
As number 8 said, clones are just another way to make another organism, but just with the same DNA. If it was up to me I would allow cloning, even though though I am overall against clones. If you would want another child, instead of making a clone, just have another child, or adopt one. I know we have the technology to clone any organism including human beings, but do we really want to use it?
