Society Increased food security for growing populations If the low success rates can be improved (Dolly was only one success out of 276 tries),reproductive cloning can be used to develop efficient ways to reliably reproduce animals with special qualities.For example,drug-producing animals or animals that have been genetically altered to serve as models for studying human disease could be mass-produced.Reproductive cloning also could be used to repopulate endangered animals or animals that are difficult to breed.In 2001,the first clone of an endangered wild animal was born,a wild ox called a gaur.The young gaur died from an infection about 48 hours after its birth.In 2001,scientists in Italy reported the successful cloning of a healthy baby mouflon,an endangered wild sheep.The cloned mouflon is living at a wildlife center in Sardinia.Other endangered species that are potential candidates for cloning include the African bongo antelope,the Sumatran tiger,and the giant panda.Cloning extinct animals presents a much greater challenge to scientists because the egg and the surrogate needed to create the cloned embryo would be of a species different from the clone.Therapeutic cloning technology may some day be used in humans to produce whole organs from single cells or to produce healthy cells that can replace damaged cells in degenerative diseases such as Alzheimer's or Parkinson's.Much work still needs to be done before therapeutic cloning can become a realistic option for the t

While cloning provides many immediately obvious benefits, it also opens a Pandora box that will destroy social orders as we know it. Human society functions based on succession of generations and on each generation's DNA being different from the previous. With cloning, both of those will be changed forever. Cloning will allow those who can afford to produce fully transplantable organs to replace their aging organs and therefore possibly live to be hundreds of years old. Some may attempt to clone a complete copy of themselves and it means two generations will have exactly the same genetic composition. With line of generations blurred and unique genetic compositions across generations no longer a guarantee, human society as we know it will no longer be possible. And once this Pandora box is opened, it can never be closed again.

Our society should encourage the development of cloning technology, for the potential benefits it can bring us. The most obvious application of cloning technology is in medical field. Instead of waiting for mercy of organ donors, you would be able to just replace your entire body with that of the cloned version of yours. In that sense, all diseases can be cured, for then your body is just like any other industrially produced products that can be replaced. So why not cloning?
