Genetic engineering Genetic engineering technology is controversial in my country. Many people are against this technology because they think is dangerous and it can be used for bad uses. In my opinión this technology will let us to advance in medicine and many diseases will be erradicated very soon. Obviously, people who have enough money will try to use to make changes superficial such as choosing color eyes for their children or sex. The goverments will have to control what type of uses these techniq will have and also they have to provide information about risks of this technology.
