I support any or all efforts to reach such a goal. Well, as long as we don't fall in to communism. I'd much rather live forever in a capitalist society than in a boring communist society.

Who wants to lose their own existance? Not me; and I'm pretty sure every human being, no matter how much they are ethically and/or morally against it, has some level of desire to continue living, and not die.

Oh, and there's a simple solution to the problem of overpopulation- have less kids. The thing is, people have too many kids; two or three should be the maximum. Also, discouraging reproduction, and, instead, encouraging education and/or entrepreneurship is another good way to help solve this problem.

Of course, with science and medical technology, we could find a way to alter the cell division process. People once thought artificial intelligence, genetic engineering, cloning, and so forth were impossible- but, as time shows, all of these ideas that would be found only in sci-fi media are coming true. Technology and science can allow us to become gods; it will take time, but there is no reason to doubt that the so-called impossible can be made possible. We've done it before; we can do it again.
