The Pros and Cons of Genetic Engineering

There is no doubt that genetic engineering has become one of the

most controversial topics in recent years. On the one hand, it

promises to bring about many benefits for humanity. On the other

hand, there are immense ethical and safety concerns associated

with it. In this essay, I will discuss both the potential positive and

negative aspects of genetic engineering.

The most apparent benefit of genetic engineering is the potential to

eliminate diseases that affect humans. As scientists are capable of

manipulating genes and replacing them with more beneficial ones,

genetic engineering can be used to rid people of inherited diseases.

This possibility gives hope to families with a history of hereditary

diseases, as generations of suffering can be put to an end.

Furthermore, genetic engineering could also be used to enhance

physical attributes and create ‘superhumans’ of various kinds.

However, genetic engineering also carries some ethical concerns.

While it has the potential to rid people of medical conditions, it

may also be used to enhance physical attributes beyond what is

natural or desirable. This could lead to a society filled with humans

who have been artificially made ‘better’ than others, which may

create serious social problems. Additionally, altering gene

composition to achieve a certain outcome does not come without

risks. It is impossible to predict the long-term effects of any

genetic modifications done on humans, and this uncertainty can

cause fear amongst people.

In conclusion, genetic engineering is a complex yet powerful

technology that can be used for both good and bad. As with all

advancements in science, it is essential to weigh the pros and cons

carefully before making any decisions.
