With word that scientists succeeded in cloning an adult mammal being spread in air, it turns to a heated discussion that whether cloning will bring fortunes or misfortunes to human society. Many believe that the advantages of cloning weigh over its disadvantages. They insist that cloning can save the rare wild lives from dying out. Also, cloning can throw light on some serious diseases. Maybe it can save peoples lives. While others argue that world with cloning is disastrous. They hold the view that cloning will destroy the ecological balance and an increasing number of transplants will be sold illegally. From their view of claim, cloning will make our world in chaos. As for me, I stick to the opinion that every coin has two sides. Thats to say, anything new-born will undoubtedly bring fortunes and misfortunes to the world. Therefore, it is we human beings that depend its trend. We should make full use of its fortunes and carefully avoid its misfortunes. In that way, I believe the future of cloning will be bright.
