Input: Consider Input: Context: I'm sure many of you have seen Star Wars, Jurassic Park, Multiplicity, or many of the other movies that describe cloning. Most of what you see in these movies is false. What you don't know is that cloning could be dangerous, to the clone and to our society as a whole. I think human cloning is wrong mainly for four reasons. What about identity? Humans are promised the right to their own personalities. What would happen if we ignore those rights by giving them someone else's genetic identity? True, Cloning may prevent people from possessing their identities. Also, these is a large power struggle here. Cloning means a degree of power and controls over another person's physical identity and that ignores their rights and their only personalities. The person doing the cloning would have more power than any parent would have. Cloning would also deal with killing embryos . You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. cloning means running the risk of wasting too much effort Cloning someone, at this present time, would be extremely dangerous to the birth mother and the clone. In studies done on cows, 4 out of 12 birth mothers died. There is a very high failure rate, which is shown in the cloning of Dolly. Even if you had a few good embryos, failures have been noticeable in animal tests. So, should we work ahead in the world of cloning? I say no. the risks are greater than the benefits. It's dangerous to the clone and to the birth mother. We would be killing human lives in the process. It would also be a violation of the clone's right to its own genetic identity and personality. 
 Question: According to the article, what is the author's opinion about identity?


Output: cloning may prevent people from possessing their identities.
