Release fears and make the chance for the healthier generation

From mechanical kinetics to the Internet, from improvements in various surgical techniques to outer space landings and embryo cloning, the development of science and technology in the 20th century has progressed at a pace beyond imagination. Especially in the last forty to fifty years. Breakthroughs in medical science have transformed and extended human life. The up coming Human Cloning technology could help us solve lots of medical problems caused by gene.

The process of creation of hereditarily identical person either living or dead is known as Human Cloning. It includes the production of clone tissue also from the individual. The presence of identical DNA makes no difference in their being different personalities. The scientific community all over the world is still investigating the question how similar the original and its clone would depend up on how much of personality is determined by genetics. But this technology do helps providing people with more choices in terms of human reproduction.

 With cloning, infertile couples could have children. Despite getting a fair amount of publicity in the news current treatments for infertility, in terms of percentages, are not very successful. One estimate is that current infertility treatments are less than 10 percent successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before possible.

Also we could fight with defective genes. The average person carries 8 defective genes inside them. These defective genes allow people to become sick when they would otherwise remain healthy. With human cloning and its technology it may be possible to chose the healthy genes for next generation and ensure that we and at least our next generation would no longer suffer because of our defective genes.

This new technology heralds a new era of unparalleled advancement in medicine if people will release their fears and let the benefits begin.
