Had to write a couple of essays on the subject at university 4 years ago, one as a scientific report on cloning, the other on the ethics of it.
Strangely enough, with all the reading I did, I didn't touch upon the subject of cloning to harvest organs in my report.
I was too fascinated with the notion that living mammals can come into existence without the use of sperm. It still leaves me in wonder. Has there ever been anything so groundbreaking in biology? Or in the history of science?
But I guess the notion of conception in a test tube was just as inconceivable 100 years ago... maybe it takes time to get used to it.
Our lives are so short in the large scheme of things; we tend to be limited in our perspectives.
As much as I find the risk of the bleakest scenarios unacceptable to me personally (deformed births, uncertain consequences involving human life)... the itch of "what if" will never go away. And I'd bet my life there are thousands of scientists out there who have that itch a thousand fold. And people willing to risk all to fund it.
To the general population, it's about 'why should we do it'? To the scientifically oriented, it's too much to pass up on. This is the kind of stuff that drives scientists more than finding the cure for Aids and cancer. It has a unifying effect, fascinating physicists, chemists as much as they do geneticists. It has broader implications than 'improving life'.
If you understand the true nature of scientific research, you'd resign yourself to the inevitability of cloning. The laws will be there to restrict (which I'm for), but as far as trying to stop it... that boat didn't just sail, it sank at the pier.
All there needs to be is one autonomous jurisdiction anywhere in the world to loosen up the restrictions, and if any good comes out of it, others will NOT want to fall behind. Statistically speaking, that’s bound to happen.
The idea of building a railway to the moon never took off, and the intended goal was achieved through different means. Cloning is already underway; it's not a hypothetical concept. The means are here... it's the goal we're not sure of.
I agree with CndPatriot, that there is an element of fear because of the lack of knowledge.
I hope people learn about the process before getting into the moral discussion. Even for those dead set against it for whatever reasons, I hope they take the time to learn what it is.
