As adults we make our decisions as best we can. We can’t not make decisions, and the ones we do affect future generations whether they like it or not. That’s just life.

Having said that I worry about the sustainability of these projects. If these are not indefinitely sustainable on arrival, then future generations are doomed to die out with no hope of survival. I’ve no problem with a carefully judged risk, there are no guarantees in life, but there has to at least be a reasonable chance.

There's no need to worry about something that will never actually happen.

Would it be any more cruel than having children as a serf on a farm, where your family has worked for countless generations, knowing that they're likely to have the same fate?

No, cause you need hands to work the land. And you end up having a dozen cause a few won't make it. /s

The whole "cruel to children" aspect is flawed. It only self-identifies individuals with a world view that is very earth-centric. We need a societal system where such a position is seen as an honorable one. That's why I liked the Antarctica bit of the submission. We ALL need to learn and change.
