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.
