Some people believe that cloning can help cure many diseases and save lots of people’s lives. However, others insist cloning is dangerous both technologically and ethically. They think cloning , especially human cloning , violates the laws the nature.
This is to encourage students’ interest in the unit topic as it may be unfamiliar to most of them. You can ask students to surf the Internet first to refer to other sources for further information
