Cloning is the process of making an exact copy on something. Human cloning is illegal in many countries and is unethical. Animal cloning has been tried and has been successful in many species from fruit flies to water buffalo. The first cloning took place in 1952 on a tadpole but, the first result of the first cloning from adult cells was Dolly the lamb in 1996. Dolly lived for 6 years and died of respiratory infection in 2003.
Cloning could save lives, because if you cloned your heart at age 18, once your 40 if you need a heart transplant you will have a perfectly good working heart says Jennifer Chan . Cloning could also be the cure to infertility. Reproductive cloning or somatic nuclear transfer, which was how Dolly was cloned. Cloning technology offers infertile couples the promise of greatly improving the odds of having a baby.
Cloning can be used to save endangered species. Rather than breeding endangered species, why not just clone them? We could also use it to advance in medicine like cancer or Parkinson's. Although most states in the U.S. have banned reproductive cloning, there are still a few states that allow it and then we might have a chance to find answers and improve the human life.
Some say cloning is very dangerous. Most countries have banned it for religious reasons or they think that it is unethcial. Political wars have been started because of biological copying. If some future dictator got a hold of cloning technology they could wipe out anything by cloning toxins and selling it to every store in the world waltzing in and taking over!
