Cons of designer babies
society
 -   A society of pretty, healthy, and intelligent people may sound reasonable and even favorable, until the full social implications are considered. Designing a baby costs money, and will most likely continue to cost lots of money; Genetic engineering for non medical reasons is not necessary for living life and it is doubtful that those who could not afford it would get reimbursed by insurance companies. This cost will mean that not everyone will be able to pay to design their baby, and suddenly people will encounter prejudice, not for their race, but for their inferior genetic makeup. It creates a new class system made up of genetically designed people and naturally made people. The people who were not genetically engineered would experience a loss of opportunity based on a chance that their defective genes will be expressed. In this new society, people with a 50% chance of cancer would get passed over for a job in favor of the person with .01% chance of cancer. That kind of social stratification can be frightening. Even if privacy laws the way they are now stay in place and people’s genetic information is not shared, it could be obvious which children were designed and which were not, creating the same stratification

one gender or other important characteristic is favored over the other.
-In countries such as China and India where boys are favored over girls, this technology could be used so that every set of parents that wants a baby boy will get one. However, that is not evolutionarily favorable. If a generation of only boys were to be made, the human race would die out.

-Without diversity in the species, adaptation to the new environment is more difficult without a wide range of individuals to choose from. The evolution of humans has spanned about 2 million years and has resulted in the types of people we see today: people who have imperfections and people who are very different from one another. A large scale of organisms in a particular species is necessary for that species to continue to be competitive with other species and be successful. By creating a generation of genetically similar people, the human species loses its ability to adapt to changing environments

going against ethical values.
-Furthermore, on moral grounds, whether it is believed that humans evolved or were created by God, it is wrong to try to perfect something that has been perfected over a large span of time or made by God. This is also considered as going against ethical values.

The Embryos

The choosing of embryos brings to the forefront a large moral issue with designer babies. Many embryos are created, and not as many are implanted into the mother. The embryos that do not fit the specifications set by the parents will get thrown away. Had these embryos have been allowed to grow, they could have had long and fulfilled lives, however the ones that are thrown away lose that potential life. Many people, especially those who are pro-life, view this aspect as a huge problem in the creation of designer babies. If many embryos are going to be thrown away, they should not be created.

Author's POV

"Genetic engineering and designer babies could potentially be a very good thing; however, like any technology, it cannot be abused without rampant ramifications. It is true that many of the scenarios mentioned are worst case. On the other hand, any degree of the scenarios above is still somewhat terrifying. We do not think that the ideas surrounding designer babies are all bad though as there are also advantages to it"
