Nowadays science has got to the point that we can edit a genomic material of a living being, it's even possible to do it with humans, but is it beneficial? Well, let's think a little bit about it.
One of the main reasons humans edit a genomic material is to get something out of it, for example, nowadays we eat a lot of GM food, that is modified genetically to grow bigger, to have more resistance agains plagues. That's one way of thinking, but we need to be careful, there's always a second side of the story, it could be used for reasons that are not ethical or that it needs to be discussed first, and that needs to be taken into consideration.
For you to modify a gene of something or someone, for example, a baby, we are going to start dealing with religion's problems, and there's a need for respect in the world nowadays, that's why this matter needs to be discussed. If you are in a college, before doing something, ask your professors about it, the area that deals with your type of study and stuff like that, that way you can avoid these problems.
