Cloning in the 21st century
Cloning is some thing that people have probably always thought about. We'll now it might happen. As of Febuary 2014 scientist have looked at human cloning. They are turning animal cells and human into totipotent cells.
We have been able to clone a sheep but never a human and it could end up happening. Only a mouse has been cloned healthy. It is more complex to clone something bigger
Cloning could be very useful. But people could take advantage of cloning. People could use them for slaves and the only useful time to clone is when you are a baby because when you are older they won't have your memories.
