From what you say, lots of people die naturally while they're still at the embryo stage. Surely with all the natural mishaps that occur that only makes the ones that do make it even more precious? Surely what they need is all our humanity and help, not our murderous intervention? - No, what I think Bee means is that lots of embryos never become people, and that is the way that nature works - you always have more than can survive so that those that do, will be the strongest. That doesn't make the ones who are not going to survive precious - it makes them expendable, and needing to be expended to keep the species going. The wolf keep the caribou strong, in other words.

And if only rich people benefit from science, that is a failing in society, not in science. The point here is to keep people from dying in ways that are preventable - like diseases and accidents - not to keep people from dying at all. Death at the end of a fulfilled life is not tragic; premature death is.
