Is it possible for human beings to live forever in the future?

I think it is possible, but this technology involves not only medical problems, but also many moral problems, so even if we have reached a considerable level in medicine and can develop drugs or other medical supplies that will make human beings live forever, it is still impossible to put it into use.

Because once human beings live forever, they have actually broken the law of the growth and development of all things in the universe to a certain extent, making the whole ecosystem chaotic. Moreover, natural selection, if human beings always choose to live forever, the world population may increase dramatically, and then everyone hopes that they can have this ability, isn't it terrible?
