Please check my essay for FCE:) "Has genetic science gone too far?" Genetic science in the science which moving forward in different ways using range of various experements. In my opinion, genetic science should move slowly in order to verify the influence of its experiments on human life. On the one hand, there are many good medical reasons for experementing with genetic engineering. It can help to trace diseases in order save the lives of millions people. In addition to that, it can help in solving famine problems in the world. Once scientists succeeded in clonning animals for food, there will be plenty of food for everyone. On the other hand, changing the way thing happen naturally can poses many risks. Working against natural order of things can cause negative effect on environment. All things considered, the genetic science needs to be more controlled in order to explore both positive and negative influence on mankind and environment, before it is too late.
