@ Funny: Thanks for Calling me, Girl! I have decided to let the land of power for "younger trees" to grow. Scientists did spend hundreds of years to prove that most trees couldn''t develop under the dark shadow of bigger ones.
But my spirit is always around you. Don''t cry for me, Argentina.

Who Will Clone?
Not all cloning would involve creating an entirely new human being. Cloning is seen as a possible way to aid some people who have severe medical problems. One potential use of cloning technology would involve creating a human repair kit. In other words, scientists could clone our cells and fix mutated genes that cause diseases. In January 2001, the British government passed rules to allow cloning of human embryos to combat diseases such as Parkinson''s and Alzheimer''s.
While it may take time for cloning to be fully accepted, therapeutic cloning will likely be the first step in that direction. Therapeutic cloning is the process by which a person''s DNA is used to grow an embryonic clone. However, instead of inserting this embryo into a surrogate mother, its cells are used to grow stem cells. These stem cells can be used as a human repair kit. They can grow replacement organs, such as hearts, livers and skin. They can also be used to grow neurons to cure those who suffer from Alzheimer''s, Parkinson''s or Rett Syndrome.
Here''s how therapeutic cloning works:
* DNA is extracted from a sick person.
* The DNA is then inserted into an enucleated donor egg.
* The egg then divides like a typical fertilized egg and forms an embryo.
* Stem cells are removed from the embryo.
* Any kind of tissue or organ can be grown from these stem cells to treat the sick.
Others see cloning as a way to aid couples with infertility problems, but who want a child with at least one of the parent''s biological attributes. Zavos and Antinori say that helping these couples is the goal of their research. Zavos said that there are hundreds of couples already lined to to pay approximately $50,000 for the service. The group said that the procedure would involve injecting cells from an infertile male into an egg, which would be inserted into the female''s uterus. Their child would look the same as the father.
Another use for human cloning could be to bring deceased relatives back to life. Imagine using a piece of your great-grandmother''s DNA to create a clone of her. In a sense, you could be the parent of your great-grandmother. This opens the door to many ethical problems, but it''s a door that could soon be opened. One American couple is paying $500,000 to Clonaid to clone their deceased daughter using preserved skin cells.

Those clones that do survive suffer from genetic abnormalities. Some clones have been born with defective hearts, lung problems, diabetes, blood vessel problems and malfunctioning immune systems. One of the more famous cases was a cloned sheep that was born but suffered from chronic hyperventilation caused by malformed arteries leading to the lungs.
Opponents of cloning point out that while we can euthanize the defective clones of other animals, it''s much more morally problematic if this happens during the human cloning process. Advocates of cloning respond that it is now easier to pick out defective embryos before they are implanted into the mother. The debate over human cloning is just beginning, but as science advances, it could be the biggest ethical dilemma of the 21st century.

Mr.Killer, developing with full of sunshine and fat land is not the good way for " younger trees " . We like obstacles, difficulties and the dark . It help us to realize that we has to grow to find the sunshine.
In difficulty, we can grow only
Under the ground of big tree, we can mature
We like your coming ^&^

Topic is cool, but I feel something not... very right with the head of it:
It can help to improve the medical and we will get benefits from this but it is inhuman.
- Shall medical be replaced with health or something else?
- Who claim it is inhuman so soon? Debate has yet to happen, right?
God bless us all!
