I suspect the cloning debate goes a lot deeper than most of what has been discussed.
The religious right is concerned that if a whole person is cloned, in the true sense of the word, then a direct copy will be produced artificially and will that copy have a soul? True cloning is making a being outside of the womb from cell scrapings, not taking a viable egg and implanting genetic material, then replanting it in the womb.
Also, we evolve steadily through mutations caused by the radiation of our sun. Even now, several new species of animals thought to be recent mutations have been discovered in the world. Cloning humans basically stops the evolutionary process for that human. If that clone has off spring naturally, the evolutionary process will continue but will have been delayed. Clone too many people and you delay evolution.
Evolution is a good thing because it enriches the species through environmental adaptation. Like, it is known evolution made us different colors to adapt to our home environments. Now, since we are more mobile, it is speculated that through interbreeding, eventually we will ‘homogenize’ into one color. Evolution gave the Black man high resistance to skin cancer and the White man high resistance to cold.
Clone animals and you might be both benefiting mankind and hurting it at the same time because you’ll be keeping any genetic disorders intact that might have phased out over time.
Pure cloning, which is not what we have today, would enable organs to be grown for transplant in tissue cultures from a cell sample of the donor.
Actually, the processes being used today are but the very first steps towards real cloning.
Besides, we have a problem with cloning food animals. Several problems in fact. The first is stopping the long term evolution of a breed and, through cloning, keep inherited diseases intact that might have been bred out. A grand example is many pure bred animals have nasty inherited diseases that are kept because of the tight inbreeding.
The second is commercial. So, we breed a low fat, more nutritious cow, and clone it. The costs for a hardy breed drop, meet is more plentiful. Well, the breeders will loose out because the end sellers will maximize profits by increasing or maintaining the price. Even today, we have enough beef to make the price at the store cheaper, but the middlemen and retailers know we will pay high prices for it and do not drop them. So, creating better, cheaper food animals will not do much to make food cheaper.
We see that now with genetically engineered vegetables. Designed to stay fresher longer, to resist diseases that ruins them in the field, to be more nourishing and easier to grow, they cost more at the cash register.
So, there are a whole range of problems involved.
Last but not least is the Chinese Problem. China has strict birth laws. One child per family unless you can afford a wavier to have another. The male child his more highly valued than the female. Female children are being aborted faster than males so now, the Chinese have a lopsided male to female ratio which is causing problems.
Suppose you have a choice of what type of child to birth? Nature balances out the sexes just fine and mixes the genetic pool thoroughly. So people decide they want more boys than girls, with higher intelligence, blue eyes, and the natural build of a football player and, suddenly, we have several hundred thousand of the guys floating around and a shortage of natural selection. That screws up evolution. It could screw up the division of the sexes.
Now, if cloning reaches the level skillful enough to wipe out selective imperfections per-birth, that is different. It is also genetic manipulation. Your family has a history of cancer, heart disease, senility at 40 and allergies. So, your doctor manipulates the genetics of sperm and egg to remove all of these traits, clones the new eggs, implants what you need and stores the rest. Your children come out better than you are, without all of the inherited problems. Good?
Well, probably, but right now we have several sections of society not happy about such possibilities.
Like, Dwarfs. They’re not real happy about knowing that, soon, their whole line could be ‘corrected’ and wiped out.
The deaf seem to have problems with this also, because many resist hearing implants, having developed a whole deaf culture. Many are not happy about the possibility that cloning could wipe out deaf culture.
How about homosexuality? Genetic manipulation and cloning could wipe them out by making their descendants ‘normal’ and the wild card genetics which produces them in the first place could be eliminated.
Then comes the possibility of ‘superbeings’. People cloned and genetically altered to be better soldiers, more resistant to pain and injury, able to put on more muscle mass, to have stronger bones, more durable, stronger, faster, better than the normal mix we have today. That opens up a nasty nest of speculative problems.
You just KNOW the big money sports industry will get into the mix, breeding future football stars, preferably with monster bodies, low intelligence, keen agility and natural aggressiveness.
There is no way we can keep cloning from being abused at this time.
Plus, would a true clone be considered a free person and have all of the rights we have? Suppose we clone 27 identical Albert Einstein’s? Would they be free people or slaves of the state?
There are a lot of things to consider and science fiction writers, thankfully, have already brought up potential problems through the years that most of us would not have thought of, in relation to cloning.
