Should Biotechnology Be Used This is the 54th day. The debate on whether biotechnology should be used to alter and echence humans has come to the fore. Personally, biotechnology ought to be utilized under limitations and supervision. True, the state-of-the-art technology carries a host of threats. One of them is about security. If a criminal changes his face to be another person by biotechnology, it will be hard to detect him and then arrest him. Consequently, odds are that he will commit more crimes and provoke other person's illegal behaviors. Nontheless, biotechnology can produces more rewards. For a start, people are able to improve health and cure fatal diseases with the help of the advanced technology, thus living a healthier and happier life. Another windfall is that biotechnology can relieve people's stress and reduce their disappointment and other negative emotions, as many researchers have proved. All in all, biotechnology should have a prominent role to play to benefit human beings in my eyes. And I believe with relative laws and policies, this technology will be widely employed and show its formidable power. I am grateful to everyone, especially to my family, friends and teachers. Good night.
