Cloning
Reproductive cloning may help human families gain children, but there’s also a benefit（益处） for the animal world. It brings hope to people eager for（渴望） children but unable to have their own or adopt. It can also bring about the recreation（再创造） of species that have long since died, allowing scientists to fully study the species as a living creature instead of simply looking at images or bones.
Many believe that cloning can be used to replace failing（衰竭的） organs. This will reduce the waiting list for organ donations and allow more people to be saved. Not only that , but because the organ is , in fact, your own organ , there would be less chance of rejection（排斥反应）.
While the cloning of body organs（器官） can help extend human life, it could also cause a lot of malpractice（玩忽职守）. Along with（随着） the ability to clone desired characters, there could be the possibility of people deliberately（故意地） reproducing undesired（不渴望的） characters. This could lead to a rise（上升） in malpractices within society.
