Humanity is not going to be wiped out. Why and how should it? Anything short of a proper extinction event will be but a set-back. We in the west don't know it anymore, but humans are very durable and very adaptable. It's why we're where we are now.
civilizations and species have appeared and disappeared from this planet. Why should humanity as whole be the exception? We are not so far away from nature that we can exist without it. There are quite a few events that have at least the potential to kill the human race of which some might be man made while other situations by nature or even cosmic events, like asteroids or super vulcanoes which are a realistic if unlikely dangers. The explosions of super vulcanoes like yellowstone caldera have the potential to turn the ecosymstem of this planet upside down. Not to mention there is still the event of mass extinction which happend millions of years ago, it might happen again in the far future. Who knows. I mean if suddenly 70% of the species on this planet (in some cases even 90%) would dissapear that would definitely have a huge effect on us as well.
We are today in a very unique position though, historically speaking, with technology like nuclear science at our hand we now possess the weapons to pretty much end human life, I know its a bit more complicated then that, but I guess its pretty obvious that a nuclear war would be a quite devastating thing. On a global scale.
Then you have the pollution, its a fact that we change our world again, on a global level, I am not going in here detail with global warming now, because I know that its again a rather complex topic and either you believe in it or you don't. But what is undeniable, is the that we as race change the face of this planet, there are already many places that are not habitable for humans and I am not only talking about Tschernobyle.
For example, we can also no longer ignore cases like the Great Pacific garbage patch where we don't even know all the consequences yet on marine biology, because particles of polymer find their way in the food chain.
The big issue for us humans is that we are currently on top of the food chain, literally, we eat our way trough nature. That means though that any changes in nature will hit us last. But when it hits us, it will be pretty hard.
I agree that destroying humanity as species would require quite some cataclysmic event on a global level, but we should not be so arrogant to believe that we are not more then a footnote for our planet, leave alone for our universe. We always had as species a huge arrogance. Time to change that or we might disappear one day really.

The universe is made of chaos, so I'd be extremely surprised if we'd ever go insane from extreme normality and lack of want.
Actually space is quite logic, if you think about it. There is not really a lot of room for chaos.
