1. Cloning is beneficial in many ways. It can help those people with no fertility to have their own babies. For the disabled people and those with fatal diseases, cloning technique will bring them a chance to recover. Endangered species can also benefit from the research of cloning because it may help them to increase their population. The agricultural industry may greatly improve both in quantity and quality because of cloning technology. To conclude, I think the research and practice of cloning should be encouraged rather than banned.

2. Cloning must be banned for it is dangerous in some aspects. Firstly it is against nature. We must draw a line for getting involved in natural events. If we are not careful, cloning may result in genetic disasters. Suppose a population of organisms had the same genetic information, then a fatal disease would wipe out the entire population. Secondly, some people may abuse the cloning technique and produce, say, a hundred Hitlers. Also, cloning may lead to ethical and emotional problems. If a child grows up knowing her mother is her sister and her father is her brother-in-law, she would suffer unbearable emotional pressures trying to establish her identity. To conclude, I think the research and practice of cloning should be banned.
