I think it's arrogance as a species. Until the sun goes, or until there's a catastrophic impact of some kind, there's no real armageddon, no apocalypse. We may end, human-kind, and other species may end, but the earth will still be here, and the earth will go on. Eventually it will repopulate, in some way.
As for kids, I'll never have any, but it doesn't have anything to do with a sense of foreboding about the future of the species. It's just not something I've ever really wanted, and I'm getting to the point in my life, age-wise, where it's too late.
