User blog comment:Glflegolas/Human Extinction -- are we approaching the Doomsday?/@comment-27723099-20150310140015

We will destroy ourselves (and most life on earth) a few days after the next world war started. USA and Russia still want more power by all means. New powers are rising. Ukraine nearly caused this war. There will be a time when we can't hold it off any longer. If some nuclear weapons are fired, everything (that survived the explosion) will be contaminated with the radioacvtivity. And it will take decades before the radioactivity falls to a level that would allow the unlikely survivors to go out of their bunkers. Nobody can survive it in the end.

That's the most likely scenario I can think of. We could probably adapt to climate changes. We can put whole regions under quarantine to stop diseases. Science usually has too strict safety rules to be any danger (a few examples: Most households regularly use stronger acids for cleaning or food than a chemist would deal with without a maximum of protection. The safest place in a nuclear power plant is probably the water pool where the used nuclear fuel is stored.). Terrorism doesn't want to destroy the world, and if they got nuclear weapons we had the same scenario as WW3. Since the sun will still need so long to cause problems, we will have found a way to leave earth until then. And a zombie apocalypse is as likely as someone forging the One Ring to rule us all.

I can't answer to any of the polls. It's like asking "What number of 1 to 10 will I roll with this dice?" There are too many possibilities. (And WW3 is not amongst them)

But one thing is for sure: We are only a part of the evolution and evolution will survive us. There will be other species that will be better adapted to the future and probably more advanced cultures, like us. But in the end only space and time will be forever.
